BACKGROUND OF THE INVENTION

Alzheimer's disease (“AD”) has long been the subject of considerable efforts to develop accurate diagnostic methods, as well as therapeutic methods. Despite these efforts, there is an unmet need for methods of accurately diagnosing AD and differentiating it from non-Alzheimer's dementia (“non-ADD”). There is also an unmet need for effective methods of treating AD.

The cylinders above zero indicate up-regulation for that specific gene while the cylinders below zero indicate down-regulation. The blue cylinders indicate the current data, which were obtained from patients with high severity of AD/Non-ADD disease. The red, grey, and yellow cylinders represent our prediction of how the pattern of the 26 dysregulated genes would look like for lower severities, i.e., ½, ¼, and ⅛ of the current data, based on the assumption that disease severity linearly correlates with the FPKM percent change.





DETAILED DESCRIPTION OF THE INVENTION
Definitions

In this application, certain terms are used which shall have the meanings set forth as follows.


As used herein, “administer”, with respect to an agent, means to deliver the agent to a subject's body via any known method. Specific modes of administration include, without limitation, intravenous, oral, sublingual, transdermal, subcutaneous, intraperitoneal and intrathecal administration.


In addition, in this invention, the various agents can be formulated using one or more routinely used pharmaceutically acceptable carriers. Such carriers are well known to those skilled in the art. For example, oral delivery systems include tablets and capsules. These can contain excipients such as binders (e.g., hydroxypropylmethylcellulose, polyvinyl pyrilodone, other cellulosic materials and starch), diluents (e.g., lactose and other sugars, starch, dicalcium phosphate and cellulosic materials), disintegrating agents (e.g., starch polymers and cellulosic materials) and lubricating agents (e.g., stearates and talc). Injectable drug delivery systems include, for example, solutions, suspensions, gels, microspheres and polymeric injectables, and can comprise excipients such as solubility-altering agents (e.g., ethanol, propylene glycol and sucrose) and polymers (e.g., polycaprylactones and PLGA's). Implantable systems include rods and discs and can contain excipients such as PLGA and polycaprylactone.


As used herein, “Alzheimer's disease” means a concurrent affliction with the following three symptoms: (i) dementia; (ii) amyloid plaques; and (iii) neurofibrillary tangles. Dementia can be diagnosed during life. Cerebral amyloid plaques and neurofibrillary tangles can, for example, be diagnosed during autopsy. This definition of Alzheimer's disease is the one provided by the National Institute of Neurological Disorders and Stroke (NINDS) of the National Institutes of Health (NIH), and is known as the “gold standard.” All disease-afflicted subjects from whom samples were taken and studied, and for which data are presented herein, are autopsy-confirmed AD, non-ADD patients, and NDCs (who were hypervalidated because they were not demented at the time of biopsy collection).


As used herein, a gene's expression level is “consistent” with that gene's expression level in corresponding synchronized cells derived from AD patients if it is the same as, or close to, that expression level. For example, assume that gene X's TPM measure in synchronized cells derived from AD patients is 10 and its TPM measure is 100 in the same type of cells derived from non-ADD (or NDC) patients that are synchronized in the same way. A subject's gene X expression level would be consistent with gene X's AD expression level if it were, for example, below 50, below 40, below 30, below 20 or, ideally, 10 or lower.


As used herein, “culturing” lymphocytes is achieved, for example, by conducting the culturing at a temperature and in a growth factor milieu permissive of cell growth. In another embodiment, “culturing” lymphocytes is performed under conditions (e.g., those described herein for proliferation) that preserve lymphocyte viability. In one embodiment, the temperature, salinity and protein milieu permissive of cell growth is 37° C., RPMI 1640 Medium with 10% fetal bovine serum (“FBS”) and 1% penicillin (“PS”). In one embodiment of this invention, the lymphocyte-culturing step is performed for more than three hours. Preferably, the lymphocyte-culturing step is performed for more than six hours (e.g., overnight). B-lymphocyte can be cultured to over-confluence, i.e., high density/μl. The high density is determined as the plateau that is typically more then 90% in the growth curve. Then, the lymphocytes are starved overnight.


Methods for obtaining lymphocytes from a subject's blood are known, and include, for example, flow cytometry, Ficoll (a hydrophilic polysaccharide that separates layers of blood), and gradient centrifugation. Additionally, in the subject methods, the lymphocytes (e.g., B lymphocytes) can be used in immortalized or primary (i.e., non-immortalized) form. Methods for immortalizing lymphocytes (e.g., B lymphocytes) are known, and include, for example, treating the lymphocytes with Epstein-Barr virus (“EBV”).


As used herein, “culturing” skin fibroblasts is achieved, for example, by conducting the culturing at a temperature and in a growth factor milieu permissive of cell growth. In another embodiment, “culturing” skin fibroblasts is performed under conditions (e.g., those described below for proliferation) that preserve skin fibroblasts viability. In one embodiment, the temperature, humidity and protein milieu permissive of cell growth is 37° C., DMEM Medium with 10% fetal bovine serum (“FBS”) and 1% penicillin (“PS”). In one embodiment of this invention, the skin fibroblast-culturing step is performed for more than three hours. Preferably, the skin fibroblast-culturing step is performed for more than six hours (e.g., overnight).


Methods for obtaining skin fibroblasts from a subject's blood are known, and include, for example, skin punch biopsy, and growing cells out of explants. When cell confluence reaches 100%, cells are passaged. Typically after two passages, fibroblasts are purified in a proportion greater than 95%.


As used herein, cells “derived” from a subject are cells that arise through culturing and/or other physical manipulation performed on cells directly removed from the subject. For example, cultured skin fibroblasts derived from a subject are those skin fibroblasts that arise through culturing a sample of skin cells (e.g., contained in a punch biopsy) directly removed from the subject.


As used herein, “diagnosing Alzheimer's disease”, with respect to a symptomatic human subject, means determining that there is greater than 50% likelihood that the subject is afflicted with Alzheimer's disease. Preferably, “diagnosing Alzheimer's disease” means determining that there is greater than 60%, 70%, 80% or 90% likelihood that the subject is afflicted with Alzheimer's disease. As used herein, the phrase “determining whether the subject is afflicted with Alzheimer's disease” is synonymous with the phrase “diagnosing Alzheimer's disease.”


As used herein, “diagnosing non-ADD”, with respect to a symptomatic human subject, means determining that there is greater than 50% likelihood that the subject is afflicted with non-ADD. Preferably, “diagnosing non-ADD” means determining that there is greater than 60%, 70%, 80% or 90% likelihood that the subject is afflicted with non-ADD. As used herein, the phrase “determining whether the subject is afflicted with non-ADD” is synonymous with the phrase “diagnosing non-ADD.”


As used herein, “expression level”, with respect to a gene, includes, without limitation, any of the following: (i) the rate and/or degree of transcription of the gene (i.e., the rate at which, and/or degree to which, the gene is transcribed into RNA); (ii) the rate and/or degree of processing of the RNA encoded by the gene; (iii) the rate and/or degree of maturation of non-protein-coding RNA encoded by the gene; (iv) the rate at which, and/or degree to which, the RNA encoded by the gene is exported; (v) the rate at which, and/or degree to which, the RNA encoded by the gene is translated (i.e., the rate at which, and/or degree to which, the RNA is translated into protein); (vi) the rate at which, and/or degree to which, the protein encoded by the gene folds; (vii) the rate at which, and/or degree to which, the protein encoded by the gene is translocated; and (viii) the level of function (e.g., enzymatic activity or binding affinity) of the protein encoded by the gene.


As used herein, a gene is “differentially expressed between corresponding synchronized cells derived from AD patients and those derived from non-ADD patients” if, for example, the gene's TPM measure in synchronized cells derived from AD patients is different than in the same type of cells derived from non-ADD patients that are synchronized in the same way. For example, gene X would be differentially expressed between corresponding synchronized cells derived from AD patients and those derived from non-ADD patients if its TPM measure in synchronized cells derived from AD patients were 10 and its TPM measure were 100 in the same type of cells derived from non-ADD patients that are synchronized in the same way.


As used herein, an agent “favorably” affects the expression level of a gene whose expression level correlates with AD if it either decreases or increases that expression toward a level correlative with a non-AD (e.g., disease-free) state. For example, if the expression level of gene X is lower in an AD patient than in a non-afflicted patient, an agent favorably affecting the expression level of that gene would increase its expression level. Similarly, if the expression level of gene X is higher in an AD patient than in a non-afflicted patient, an agent favorably affecting the expression level of that gene would decrease its expression level.


As used herein, “measuring” the expression level of a gene means quantitatively determining the expression level via any means for doing so (e.g., Total RNA Sequencing (20 million reads, 2x75 bp PE)). Preferably, measuring the expression level of a gene is accomplished by measuring the number of RNA transcripts for that gene per million total RNA transcripts (i.e., “TPM” via FastQ data, and FPKM estimation per sample) present in the cell-derived RNA population being studied. For example, measuring the expression level of gene X in a synchronized cell population might yield a result of 50 TPM. In another embodiment, measuring a gene's expression level is done via protein quantification (e.g., via the known method of Western blotting). In a further embodiment, measuring a gene's expression level is done via a quantitative assay for protein function (e.g., via known methods for measuring enzymatic activity and/or protein binding strength).


As used herein, a subject afflicted with “non-Alzheimer's dementia” means a subject showing dementia such as, for example, that which characterizes Parkinson's disease, Huntington's disease and frontotemporal dementia.


As used herein, a “population” of cells includes any number of cells permitting the manipulation and study required to assess gene expression. In one embodiment, the population of cells includes at least 1,000,000 cells. In another embodiment, the population of cells includes between 100,000 cells and 1,000,000 cells, between 10,000 cells and 100,000 cells, between 1,000 cells and 10,000 cells, between 100 cells and 1,000 cells, between 10 cells and 100 cells, and fewer than 10 cells (e.g., one cell).


As used herein, the term “subject” includes, without limitation, a mammal such as a human, a non-human primate, a dog, a cat, a horse, a sheep, a goat, a cow, a rabbit, a pig, a rat and a mouse. Where the subject is human, the subject can be of any age. For example, the subject can be 50 years or older, 55 years or older, 60 years or older, 65 or older, 70 or older, 75 or older, 80 or older, 85 or older, or 90 or older. The instant methods are envisioned for all subjects, preferably humans (and preferably symptomatic).


As used herein, a human subject who is “suspected of being afflicted with AD or non-ADD” is a subject displaying at least one symptom (e.g., dementia) consistent with both AD and non-ADD.


As used herein, “synchronizing” a population of cells means placing at least a majority of cells in that population in the same cell cycle stage (namely, in the G1, S, G2 or M stage, and preferably in the G1, S or G2 stage). In one embodiment, synchronizing a population of cells means placing at least 60%, at least 70%, at least 80%, at least 90%, at least 95% or preferably at least 99% of cells in that population in the same cell cycle stage. In another embodiment, synchronizing a population of cells means placing the cells in that population in the same cell cycle stage that they would be in if cultured to over-confluence and then starved. Cell confluence followed by serum starvation typically arrests the cells in the G0/G1 stage [1-3].


Doses, i.e., “therapeutically effective amounts”, used in connection with this invention include, for example, a single administration, and two or more administrations (i.e., fractions). In one embodiment, the therapeutically effective amount of a drug approved for a non-Alzheimer's indication is the dose and dosing regimen approved for that non-Alzheimer's indication.


As used herein, “treating” a subject afflicted with a disorder shall include, without limitation, (i) slowing, stopping or reversing the disorder's progression, (ii) slowing, stopping or reversing the progression of the disorder's symptoms, (iii) reducing the likelihood of the disorder's recurrence, and/or (iv) reducing the likelihood that the disorder's symptoms will recur. In the preferred embodiment, treating a subject afflicted with a disorder means (i) reversing the disorder's progression, ideally to the point of eliminating the disorder, and/or (ii) reversing the progression of the disorder's symptoms, ideally to the point of eliminating the symptoms.


The treatment of AD can be measured according to a number of clinical endpoints. These include, without limitation, (a) lowering, stabilizing or slowing progression of (i) dementia, (ii) synaptic loss, (iii) amyloid plaques and/or (iv) neurofibrillary tangles, and/or (b) favorably affecting the expression level of a gene whose expression level correlates with AD.


Embodiments of the Invention

This invention provides accurate gene-based methods for determining whether a human subject is afflicted with AD or non-ADD when the subject is suspected of being afflicted with AD or non-ADD. The subject methods are based, at least in part, on the surprising discovery that synchronizing a patient's suitable cell population (e.g., lymphocytes, skin fibroblasts, pluripotent cells (such as iPSCs, and any progeny thereof)) and then measuring the expression levels of genes that are differentially expressed between AD and non-ADD cells permits accurately diagnosing the patient as having either AD or non-ADD. This invention also provides methods for treating AD using certain gene expression-altering agents.


Specifically, this invention provides a method for determining whether a human subject is afflicted with AD or non-ADD when the subject is suspected of being afflicted with AD or non-ADD, comprising the steps of

    • (a) synchronizing a population of suitable cells derived from the subject; and
    • (b) in the resulting synchronized cell population, measuring the expression level of a gene known to be differentially expressed between corresponding synchronized cells derived from AD patients and those derived from non-ADD patients,


whereby (i) the subject is afflicted with AD if the expression level measured in step (b) is consistent with that gene's expression level in corresponding synchronized cells derived from AD patients, and (ii) the subject is afflicted with non-ADD if the expression level measured in step (b) is consistent with that gene's expression level in corresponding synchronized cells derived from non-ADD patients.


In one embodiment of the subject method, the suitable cells derived from the subject are cultured skin cell fibroblasts. In another embodiment, the suitable cells derived from the subject are cultured B lymphocytes (preferably immortalized B lymphocytes).


Methods for synchronizing cell populations are known in the art. In one embodiment of the subject method, synchronizing the population of suitable cells comprises culturing the cells to over-confluence and then starving the resulting over-confluent cells.


Ideally in the subject method, the gene is known to be differentially expressed by a significant margin. In one embodiment, the gene is known to be differentially expressed by at least 50% between corresponding synchronized cells derived from AD patients and those derived from non-ADD patients. Preferably, the gene is known to be differentially expressed by at least 100% between corresponding synchronized cells derived from AD patients and those derived from non-ADD patients. Another way of expressing the degree of differential expression is “% change” or “% Ch”, which is equal to [ADexpression−Non-ADDexpression/Non-ADDexpression].


In another preferred embodiment of the subject method, the gene is selected from the group consisting of CFAP97, LINC01393, ZNF623, HAUS2, PAN3, PSMB9, ZFP28, TTC26, RFESDP1, ZNF444, WASF2, NHLH1, NPPA-AS1_3, NORAD, URB2, ADAM20, ZCWPW2, AC004057.1, AC092651.1, ACP6, ACP2, C2CD5, CARNS1, FAM149B1, GLIS3-AS1, ASXL2 and IL18R1.


In one embodiment, the gene expression levels set forth in Table 9, taken individually or collectively (e.g., one, two or more, three or more, four or more, and the like), are indicative of AD. In a preferred embodiment, the gene expression levels set forth in Table 10, taken individually or collectively (e.g., one, two or more, three or more, four or more, and the like), are indicative of AD. For example, as shown in Table 10, a PSMB9 expression level greater than 18 TPM is indicative of AD. In yet another embodiment, AD-indicative expression levels for each other gene disclosed herein are readily determined based on the data presented.


In a further preferred embodiment of the subject method, step (b) comprises measuring the expression levels of a plurality of genes, each gene being known to be differentially expressed between corresponding synchronized cells derived from AD patients and those derived from non-ADD patients. The plurality of genes can be of any suitable size, such as at least two genes, at least five genes, at least 20 genes, at least 100 genes, and at least 1,000 genes. Preferably, each gene of the plurality of genes is known to be differentially expressed by at least 50% (and more preferably by at least 100%) between corresponding synchronized cells derived from AD patients and those derived from non-ADD patients. In yet another preferred embodiment of the subject method, the plurality of genes comprises two or more genes selected from the group consisting of AC004057.1, AC092651.1, ACP6, ADAM20, ASXL2, C2CD5, CARNS1, FAM149B1, GLIS3-AS1, IL18R1, LINC01393, LZIC, MAP1LC3B2, NHLH1, NORAD, NPPA-AS1_3, OSMR-AS1, PAN3, PHBP8, PSMB9, RAB31P, RDH16, RFESDP1, RPL5, SCG2, SDHD, SHISA5, SLC45A3, SNHG14, TTC26, URB2, USMG5, WASF2, ZCWPW2, ZNF444, and ZNF70.


In the subject method where the expression levels of a plurality of genes are measured, the expression levels measured in step (b) are “consistent” with those in corresponding synchronized cells derived from AD patients if, for example, for at least a majority of gene expression levels measured, each such level is independently consistent with that gene's expression level in corresponding synchronized cells derived from AD patients.


In the subject method, measuring the expression level of a gene can be accomplished by any suitable method known in the art. In the preferred embodiment, measuring the expression level of a gene comprises measuring the number of that gene's RNA transcripts per number of total transcripts.


In a preferred embodiment, the subject invention provides a method for determining whether a human subject is afflicted with AD or non-ADD when the subject is suspected of being afflicted with AD or non-ADD, comprising the steps of

    • (a) synchronizing a population of cultured skin cell fibroblasts derived from the subject, wherein the synchronizing comprises culturing the fibroblasts to over-confluence and then starving the resulting over-confluent fibroblasts; and

This invention further provides a method for determining whether a human subject is afflicted with AD, non-ADD, or a disorder which is neither (i.e., a non-demented subject (also referred to as “NDS”, “NDS patient”, “NDS subject”, “NDC” (i.e., non-demented control), “NDC patient”, and “NDC subject”)) when the subject is suspected of being afflicted with AD or non-ADD, comprising the steps of

    • (a) synchronizing a population of suitable cells derived from the subject; and
    • (b) in the resulting synchronized cell population, measuring the expression level of a gene known to be differentially expressed between corresponding synchronized cells derived from AD patients, those derived from non-ADD patients and those derived from NDS subjects,


whereby (i) the subject is afflicted with AD if the expression level measured in step (b) is consistent with that gene's expression level in corresponding synchronized cells derived from AD patients, (ii) the subject is afflicted with non-ADD if the expression level measured in step (b) is consistent with that gene's expression level in corresponding synchronized cells derived from non-ADD patients, and (iii) the subject is afflicted with neither AD not non-ADD if the expression level measured in step (b) is consistent with that gene's expression level in corresponding synchronized cells derived from NDS subjects. The various embodiments of the diagnostic methods above for determining whether a human subject is afflicted with AD or non-ADD apply, mutatis mutandis, to this method.


This invention provides a method for determining whether a human subject is afflicted with AD or is a NDS when the subject is suspected of being afflicted with AD, comprising the steps of

    • (a) synchronizing a population of suitable cells derived from the subject; and
    • (b) in the resulting synchronized cell population, measuring the expression level of a gene known to be differentially expressed between corresponding synchronized cells derived from AD patients and those derived from NDS patients,


whereby (i) the subject is afflicted with AD if the expression level measured in step (b) is consistent with that gene's expression level in corresponding synchronized cells derived from AD patients, and (ii) the subject is a NDS if the expression level measured in step (b) is consistent with that gene's expression level in corresponding synchronized cells derived from NDS patients.


This invention also provides a method for determining whether a human subject is afflicted with AD or is a NDS when the subject is not suspected of being afflicted with AD, comprising the steps of

    • (a) synchronizing a population of suitable cells derived from the subject; and
    • (b) in the resulting synchronized cell population, measuring the expression level of a gene known to be differentially expressed between corresponding synchronized cells derived from AD patients and those derived from NDS patients,


whereby (i) the subject is afflicted with AD if the expression level measured in step (b) is consistent with that gene's expression level in corresponding synchronized cells derived from AD patients, and (ii) the subject is a NDS if the expression level measured in step (b) is consistent with that gene's expression level in corresponding synchronized cells derived from NDS patients.


In one embodiment of the subject method, the suitable cells derived from the subject are cultured skin cell fibroblasts. In another embodiment, the suitable cells derived from the subject are cultured B lymphocytes (preferably immortalized B lymphocytes).


Ideally in the subject method, the gene is known to be differentially expressed by a significant margin. In one embodiment, the gene is known to be differentially expressed by at least 50% between corresponding synchronized cells derived from AD patients and those derived from NDS patients. Preferably, the gene is known to be differentially expressed by at least 100% between corresponding synchronized cells derived from AD patients and those derived from NDS patients. Another way of expressing the degree of differential expression is “% change” or “% Ch”, which is equal to [ADexpression−NDSexpression/NDSexpression].


In a further preferred embodiment of the subject method, step (b) comprises measuring the expression levels of a plurality of genes, each gene being known to be differentially expressed between corresponding synchronized cells derived from AD patients and those derived from NDS patients. The plurality of genes can be of any suitable size, such as at least two genes, at least five genes, at least 20 genes, at least 100 genes, and at least 1,000 genes. Preferably, each gene of the plurality of genes is known to be differentially expressed by at least 50% (and more preferably by at least 100%) between corresponding synchronized cells derived from AD patients and those derived from NDS patients.


This invention further provides a method for treating a human subject afflicted with Alzheimer's disease comprising administering to the subject a therapeutically effective amount of an agent known to favorably affect the expression level of one or more genes whose expression levels correlate with Alzheimer's disease. Preferably, the genes are selected from the group consisting of AC004057.1, AC092651.1, ACP6, ADAM20, ASXL2, C2CD5, CARNS1, FAM149B1, GLIS3-AS1, IL18R1, LINC01393, LZIC, MAP1LC3B2, NHLH1, NORAD, NPPA-AS1_3, OSMR-AS1, PAN3, PHBP8, PSMB9, RAB31P, RDH16, RFESDP1, RPL5, SCG2, SDHD, SHISA5, SLC45A3, SNHG14, TTC26, URB2, USMG5, WASF2, ZCWPW2, ZNF444, and ZNF70. In one embodiment, the genes are selected from the group consisting of IL18R1, PSMB9, TTC26, WASF2, ACP6, CARNS1, NPPA-AS1_3, SCG2 and SDHD. In another embodiment, the gene is IL18R1, PSMB9, TTC26, WASF2, ACP6, CARNS1, NPPA-AS1_3, SCG2 or SDHD.

Example 2—Study 2; Synchronized Cell Cycle Gene Expression Test for Alzheimer's Disease; Cross-Validation of Genetic Differential Expression

The initial findings of the gene differential expression in synchronized skin fibroblasts, between the Alzheimer's Disease patients (AD; n=6) and the Non-Alzheimer's Disease Demented patients (Non-ADD; n=2), were cross-correlated with the second batch of samples (AD; n=2; Non-AD n=3). For the purpose of separating the two batches of samples, we called the first set of samples the “Training Set” and the second set of samples the “Validation Set.”


Methods


The genes were ranked in decreasing statistical significance order, i.e., with the highest statistical significance first (examples in Tables 4 and 5). The ranking is based on the t-test (two tailed, unequal variance) for the two groups of samples AD and Non-ADD. The comparison of the two lists of genes was made as described below.


Results


The number of statistically significant genes is similar in the training and validation sets (FIG. 8), with smaller differences for lower statistical significance (P<0.10) and larger differences for higher statistical significance (P<0.001). The larger difference for the higher statistical significance (P<0.001) could be due not only to the different number of samples in the validation set (5) when compared to the training set (8), but also to the different types of Non-ADD samples in the two sets. This difference suggests a high diversity of dysregulated pathways.


The majority of the genes (n=53) presented in Tables 4 and 5 are under highest statistical significance (P<0.001), and all of them are under high statistical significance (P<0.01). The presence of the first 40 genes from the training set (Table 4) was checked in the list of 2,077 genes from the validation set (P<0.10; FIG. 8). Similarly, the presence of the first 40 genes from the validation set (Table 5) was checked in the list of 2,103 genes from the training set (P<0.10; FIG. 8). The first 40 genes from Tables 4 and 5 are under highest statistical significance therefore it is very likely to have the highest impact in Alzheimer's disease detection, treatment, and pathways dysregulation. The cross-correlation of the first 40 genes in each set was made with a larger pool of genes from the opposite set (P<0.10) to accommodate the diversity in Non-ADD samples as well as to compensate for different numbers of samples in the validation (5) and training sets (8). However, in the end only the genes with similar statistical significance are considered as representing the core of dysregulation for AD.


The results of these initial findings in the highest statistically significant 40 genes suggests that about 81% of the genes which are dysregulated the training set are also dysregulated in the validation set. However, only about 7.5% of these genes show the same statistical significance in both training and validation set (Table 6).


Those genes showing the same statistical significance in the training and validation sets are at the core of the dysregulated pathways and will be very likely at the core of the genetic biomarkers for AD and at the core of the therapeutic targets for AD.

alias for



LOC100420889


3
ACP6
This gene encodes a member of the histidine acid phosphatase protein




family. The encoded protein hydrolyzes lysophosphatidic acid, which is




involved in G protein-coupled receptor signaling, lipid raft modulation,




and in balancing lipid composition within the cell. Alternative splicing




results in multiple transcript variants. ACP6-001-Acid phosphatase 6


4
ADAM20
This gene encodes a member of the ADAM (a disintegrin and




metalloprotease domain) family. Members of this family are membrane-




anchored proteins structurally related to snake venom disintegrins, and




have been implicated in a variety of biological processes involving cell-




cell and cell-matrix interactions, including fertilization, muscle




development, and neurogenesis. The expression of this gene is testis-




specific. Disintegrin and metalloproteinase domain-containing protein 20


5
ASXL2
This gene encodes a member of a family of epigenetic regulators that




bind various histone-modifying enzymes and are involved in the




assembly of transcription factors at specific genomic loci. Naturally




occurring mutations in this gene are associated with cancer in several




tissue types (breast, bladder, pancreas, ovary, prostate, and blood). This




gene plays an important role in neurodevelopment, cardiac function,




adipogenesis, and osteoclastogenesis. Putative Polycomb group protein




ASXL2


6
C2CD5
C2 domain-containing protein 5


7
CARNS1
CARNS1 (EC 6.3.2.11), a member of the ATP-grasp family of ATPases,




catalyzes the formation of carnosine (beta-alanyl-L-histidine) and




homocarnosine (gamma-aminobutyryl-L-histidine), which are found




mainly in skeletal muscle and the central nervous system, respectively




(Drozak et al., 2010). Carnosine synthase 1. Catalyzes the synthesis of




carnosine and homocarnosine. Carnosine is synthesized more efficiently




than homocarnosine.

GLIS3-AS1
GLIS3 Antisense RNA 1.


10
IL18R1
The protein encoded by this gene is a cytokine receptor that belongs to




the interleukin 1 receptor family. This receptor specifically binds




interleukin 18 (IL18), and is essential for IL18 mediated signal




transduction. IFN-alpha and IL12 are reported to induce the expression




of this receptor in NK and T cells. This gene along with four other




members of the interleukin 1 receptor family, including IL1R2, IL1R1,




ILRL.2 (IL-1 Rrp2), and IL1RL1 (T1/ST2), form a gene cluster on




chromosome 2q. Alternatively spliced transcript variants encoding




different isoforms have been found for this gene. Interleukin-18 receptor




1.

Long Intergenic Non-Protein Coding RNA 1393.


12
LZIC
Leucine zipper and CTNNBIP1 domain containing, isoform CRA_a.




Protein LZIC.


13
IMAP1LC3B2
Microtubule associated protein 1 light chain 3 beta 2.


14
NHLH1
The helix-loop-helix (HLH) proteins are a family of putative transcription




factors, some of which have been shown to play an important role in




growth and development of a wide variety of tissues and species. Four




members of this family have been clearly implicated in tumorigenesis via




their involvement in chromosomal translocations in lymphoid tumors:




MYC (MUM 190080), LYL1 (MIM 151440), E2A (MIM 147141), and SCL




(MIM 187040). Helix-loop-helix protein 1.


15
NORAD
Non-Coding RNA Activated By DNA Damage. Lee et al. (2016) found




that DNA damage induced NORAD expression in a p53 (TP53; 191170)-




dependent manner in HCT116 human colon cancer cells. Conditional




knockout or knockdown of NORAD expression caused multiple mitotic




errors, including anaphase bridges, mitotic slippage, and significant




aneuploidy. Mass spectrometric analysis of proteins that bound to




NORAD identified Pumilio-2 (PUM2; 607205), a protein that destabilizes




mRNAs by binding to PREs in their 3-prime UTRs. NORAD functions as




a molecular decoy for Pumilio proteins and stabilizes Pumilio target




mRNAs. Using combined RNA antisense purification and quantitative




mass spectrometry, Munschauer et al. (2018) showed that NORAD




interacts with proteins involved in DNA replication and repair in steady-




state cells and localizes to the nucleus upon stimulation with replication




stress or DNA damage. Cells depleted for NORAD or RBMX displayed




an increased frequency of chromosome segregation defects, reduced




replication fork velocity, and altered cell-cycle progression.


16
NPPA-AS1_3
Non-protein coding gene


17
OSMR-AS1
An RNA Gene, and is affiliated with the non-coding RNA class. OSMR =




Oncostatin M receptor This gene encodes a member of the type I




cytokine receptor family. The encoded protein heterodimerizes with




interleukin 6 signal transducer to form the type II oncostatin M receptor




and with interleukin 31 receptor A to form the interleukin 31 receptor,




and thus transduces oncostatin M and interleukin 31 induced signaling




events. Mutations in this gene have been associated with familial




primary localized cutaneous amyloidosis.


18
PAN3
PAN3 poly(A) specific ribonuclease subunit.PAB-dependent poly(A)-




specific ribonuclease subunit PAN3. The N-terminal zinc finger binds to




poly(A) RNA. Belongs to the protein kinase superfamily. PAN3 family.




Regulatory subunit of the poly(A)-nuclease (PAN) deadenylation




complex, one of two cytoplasmic mRNA deadenylases involved in




general and miRNA-mediated mRNA turnover. PAN specifically shortens




poly(A) tails of RNA and the activity is stimulated by poly(A)-binding




protein (PABP). PAN deadenylation is followed by rapid degradation of




the shortened mRNA tails by the CCR4-NOT complex. Deadenylated




mRNAs are then degraded by two alternative mechanisms, namely




exosome-mediated 3′-5′ exonucleolytic degradation, or deadenlyation-




dependent mRNA decapping and subsequent 5′-3′ exonucleolytic




degradation by XRN1. PAN3S acts as a positive regulator for PAN




activity, recruiting the catalytic subunit PAN2 to mRNA via its interaction




with RNA and PABP, and to miRNA targets via its interaction with




GW182 family proteins.


19
PHBP8
Prohibitin Pseudogene 8.


20
PSMB9
Proteasome subunit beta 9




The proteasome is a multicatalytic proteinase complex with a highly




ordered ring-shaped 20S core structure. The core structure is composed




of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha




subunits and 2 rings are composed of 7 beta subunits. Proteasomes are




distributed throughout eukaryotic cells at a high concentration and




cleave peptides in an ATP/ubiquitin-dependent process in a non-




lysosomal pathway. An essential function of a modified proteasome, the




immunoproteasome, is the processing of class I MHC peptides. This




gene encodes a member of the proteasome B-type family, also known




as the T1B family, that is a 20S core beta subunit. This gene is located




in the class II region of the MHC (major histocompatibility complex).




Expression of this gene is induced by gamma interferon and this gene




product replaces catalytic subunit 1 (proteasome beta 6 subunit) in the




immunoproteasome. Proteolytic processing is required to generate a




mature subunit.


21
RAB3IP
RAB3A interacting protein is a Protein Coding gene. Among its related




pathways are Cargo trafficking to the periciliary membrane and Vesicle-




mediated transport.


22
RDH16

23
RFESDP1
Rieske (Fe—S) Domain Containing Pseudogene 1 is a Rieske (Fe—S)




Domain Containing Pseudogene 1.


24
RPL5
Ribosomal protein L5. Ribosomes, the organelles that catalyze protein




synthesis, consist of a small 40S subunit and a large 60S subunit.




Together these subunits are composed of four RNA species and




approximately 80 structurally distinct proteins. This gene encodes a




member of the L18P family of ribosomal proteins and component of the




60S subunit. The encoded protein binds 5S rRNA to form a stable




complex called the 5S ribonucleoprotein particle (RNP), which is




necessary for the transport of nonribosome-associated cytoplasmic 5S




rRNA to the nucleolus for assembly into ribosomes. The encoded protein




may also function to inhibit tumorigenesis through the activation of




downstream tumor suppressors and the downregulation of oncoprotein




expression. Mutations in this gene have been identified in patients with




Diamond-Blackfan Anemia (DBA). This gene is co-transcribed with the




small nucleolar RNA gene U21, which is located in its fifth intron. As is




typical for genes encoding ribosomal proteins, there are multiple




processed pseudogenes of this gene dispersed throughout the genome.


25
SCG2
Secretogranin II. The protein encoded by this gene is a member of the




chromogranin/secretogranin family of neuroendocrine secretory proteins.




Studies in rodents suggest that the full-length protein, secretogranin II, is




involved in the packaging or sorting of peptide hormones and




neuropeptides into secretory vesicles. The full-length protein is cleaved




to produce the active peptide secretoneurin, which exerts chemotaxic




effects on specific cell types, and EM66, whose function is unknown


26
SDHD
Succinate Dehydrogenase Complex Subunit D. This gene encodes a




member of complex II of the respiratory chain, which is responsible for




the oxidation of succinate. The encoded protein is one of two integral




membrane proteins anchoring the complex to the matrix side of the




mitochondrial inner membrane. Mutations in this gene are associated




with the formation of tumors, including hereditary paraganglioma.




Transmission of disease occurs almost exclusively through the paternal




allele, suggesting that this locus may be maternally imprinted. There are




pseudogenes for this gene on chromosomes 1, 2, 3, 7, and 18.




Alternative splicing results in multiple transcript variant


27
SHISA5
Shisa family member 5. This gene encodes a member of the shisa




family. The encoded protein is localized to the endoplasmic reticulum,




and together with p53 induces apoptosis in a caspase-dependent




manner. Alternative splicing results in multiple transcript variants.




Related pseudogenes of this gene are found on chromosome X. Can




induce apoptosis in a caspase-dependent manner and plays a role in




p53/TP53-dependent apoptosis. Induced in a p53/TP53-dependent




manner in response to cellular stress.


28
SLC45A3
Solute carrier family 45 member 3. Hexose transport. Transport of




glucose and other sugars, bile salts and organic acids, metal ions and




amine compounds. Phenotype: microRNAs in cancer, transcriptional




misregulation in cancer, and metabolism.


29
SNHG14
Small Nucleolar RNA Host Gene 14. This gene is located within the




Prader-Willi Syndrome critical region on chromosome 15 and is




imprinted and expressed from the paternal allele. It encodes a




component of the small nuclear ribonucleoprotein complex, which




functions in pre-mRNA processing and may contribute to tissue-specific




alternative splicing. Alternative promoter use and alternative splicing




result in a multitude of transcript variants encoding the same protein.




Transcript variants that initiate at the CpG island-associated imprinting




center may be bicistronic and also encode the SNRPN upstream reading




frame protein (SNURF) from an upstream open reading frame. In




addition, long spliced transcripts for small nucleolar RNA host gene 14




(SNHG14) may originate from the promoters at this locus and share




exons with this gene. Alterations in this region are associated with




parental imprint switch failure, which may cause Angelman syndrome or




Prader-Willi syndrome.


30
TTC26
Tetratricopeptide Repeat Domain 26. Cytoplasmic expression in few




tissues, distinct in cilia. Component of the intraflagellar transport (IFT)




complex B required for transport of proteins in the motile cilium.




Required for transport of specific ciliary cargo proteins related to motility,




while it is neither required for IFT complex B assembly or motion nor for




cilium assembly. Required for efficient coupling between the




accumulation of GLI2 and GLI3 at the ciliary tips and their dissociation




from the negative regulator SUFU. Plays a key role in maintaining the




integrity of the IFT complex B and the proper ciliary localization of the




IFT complex B components. Not required for IFT complex A ciliary




localization or function. Essential for maintaining proper microtubule




organization within the ciliary axoneme.


31
URB2
URB2 ribosome biogenesis 2 homolog. High density


32
USMG5 alias
Up-regulated during skeletal muscle growth 5 homolog. Plays a critical



for ATP5MD
role in maintaining the ATP synthase population in mitochondria.




USMG5_HUMAN, Q96IX5 Transactivated by SBP1.


33
WASF2
WASP Family Member 2, This gene encodes a member of the Wiskott-




Aldrich syndrome protein family. The gene product is a protein that




forms a multiprotein complex that links receptor kinases and actin.




Binding to actin occurs through a C-terminal verprolin homology domain




in all family members. The multiprotein complex serves to tranduce




signals that involve changes in cell shape, motility or function. The




published map location (PMID: 10381382) has been changed based on




recent genomic sequence comparisons, which indicate that the




expressed gene is located on chromosome 1, and a pseudogene may




be located on chromosome X. Two transcript variants encoding different




isoforms have been found for this gene. Downstream effector molecule




involved in the transmission of signals from tyrosine kinase receptors




and small GTPases to the actin cytoskeleton. Promotes formation of




actin filaments. Part of the WAVE complex that regulates lamellipodia




formation. The WAVE complex regulates actin filament reorganization




via its interaction with the Arp 2/3 complex.


34
ZCWPW2
Zinc Finger CW-Type And PWWP Domain Containing 2.


35
ZNF444
Zinc finger protein 444. This gene encodes a zinc finger protein that




activates transcription of a scavenger receptor gene involved in the




degradation of acetylated low density lipoprotein (Ac-LDL) (PMID:




11978792). This gene is located in a cluster of zinc finger genes on




chromosome 19 at q13.4. A pseudogene of this gene is located on




chromosome 15. Multiple transcript variants encoding different isoforms




have been found for this gene.


36
ZNF70

Example 3—Study 2; TPM Values

Reference Intervals


The average and standard deviations were calculated for the transcripts per million (TPM) values for each of the two groups—Alzheimer's disease (AD) and Non-Alzheimer's Disease Demented (Non-ADD) for each gene. The reference intervals were then calculated according to Horn and Pesce (Reference Intervals: A User's Guide. Paul S. Horn and Amadeo J. Pesce. Washington, D.C.: AACC Press, 2005, ISBN 1-59425-035-9) as the average plus minus two standard deviations. The reference intervals calculated in this way assure that 95% of all the possible values in each population (AD or non-ADD) are considered.


Gap Between AD and Non-ADD


If there is no overlap between the reference intervals of AD and Non-ADD, there is a gap between the two bell-shaped curves and that indicates unequivocal diagnosis.


If there is an overlap in the reference intervals for AD and Non-ADD (light grey in Table 9), then there is a possibility of having a false positive or a false negative in the diagnosis. The genes that show overlap in the reference intervals, i.e., no gap (light grey) were eliminated from the final vector diagnosis. The genes that show an average of zero in one of the groups, either in the AD group or in the Non-ADD group, were also eliminated.


Cut-Off for Each Gene


The cut-offs for each of the remaining 26 genes (Table 10) was determined as the middle of the gap in the reference intervals.


Genetic Vector AD Diagnosis


The AD diagnosis is based on the 26 components/genes of the vector. For each one of the components, the greater than (>) or smaller than (<) the cut-off value is indicated for each gene, in the last column.

Claims
  • 1.-23. (canceled)
  • 24. A method for determining whether a human subject is afflicted with AD or is a NDS when the subject is suspected of being afflicted with AD, comprising the steps of (a) synchronizing a population of suitable cells derived from the subject; and(b) in the resulting synchronized cell population, measuring the expression level of a gene known to be differentially expressed between corresponding synchronized cells derived from AD patients and those derived from NDS patients,
  • 25. The method of claim 24, wherein the suitable cells derived from the subject are cultured skin cell fibroblasts.
  • 26. The method of claim 24, wherein the suitable cells derived from the subject are cultured B lymphocytes.
  • 27. The method of claim 26, wherein the B lymphocytes are immortalized.
  • 28. The method of claim 24, wherein synchronizing the population of suitable cells comprises culturing the cells to over-confluence and then starving the resulting over-confluent cells.
  • 29. The method of claim 24, wherein the gene is known to be differentially expressed by at least 50% between corresponding synchronized cells derived from AD patients and those derived from NDS patients.
  • 30. The method of claim 29, wherein the gene is known to be differentially expressed by at least 100% between corresponding synchronized cells derived from AD patients and those derived from NDS patients.
  • 31. The method of claim 24, wherein the gene is selected from the group consisting of AC004057.1, ACP6, ADAM20, RPL5, SHISA5, SNHG14, WASF2 and ZNF444.
  • 32. The method of claim 24, wherein step (b) comprises measuring the expression levels of a plurality of genes, each gene being known to be differentially expressed between corresponding synchronized cells derived from AD patients and those derived from NDS patients.
  • 33. The method of claim 32, wherein the plurality of genes is selected from the group consisting of at least two genes, at least five genes, at least 20 genes, at least 100 genes, and at least 1,000 genes.
  • 34. The method of claim 32, wherein each gene of the plurality of genes is known to be differentially expressed by at least 50% between corresponding synchronized cells derived from AD patients and those derived from NDS patients.
  • 35. The method of claim 34, wherein each gene of the plurality of genes is known to be differentially expressed by at least 100% between corresponding synchronized cells derived from AD patients and those derived from NDS patients.
  • 36. The method of claim 32, wherein the plurality of genes comprises two or more genes selected from the group consisting of AC004057.1, ACP6, ADAM20, RPL5, SHISA5, SNHG14, WASF2 and ZNF444.
  • 37. The method of claim 24, wherein measuring the expression level of a gene comprises measuring the number of that gene's RNA transcripts per number of total transcripts.
  • 38. A method for determining whether a human subject is afflicted with AD or is a NDS when the subject is not suspected of being afflicted with AD, comprising the steps of (a) synchronizing a population of suitable cells derived from the subject; and(b) in the resulting synchronized cell population, measuring the expression level of a gene known to be differentially expressed between corresponding synchronized cells derived from AD patients and those derived from NDS patients,
  • 39. The method of claim 38, wherein the suitable cells derived from the subject are cultured skin cell fibroblasts.
  • 40. The method of claim 38, wherein the suitable cells derived from the subject are cultured B lymphocytes.
  • 41. The method of claim 40, wherein the B lymphocytes are immortalized.
  • 42. The method of claim 38, wherein synchronizing the population of suitable cells comprises culturing the cells to over-confluence and then starving the resulting over-confluent cells.
  • 43. The method of claim 38, wherein the gene is known to be differentially expressed by at least 50% between corresponding synchronized cells derived from AD patients and those derived from NDS patients.
  • 44. The method of claim 43, wherein the gene is known to be differentially expressed by at least 100% between corresponding synchronized cells derived from AD patients and those derived from NDS patients.
  • 45. The method of claim 38, wherein the gene is selected from the group consisting of AC004057.1, ACP6, ADAM20, RPL5, SHISA5, SNHG14, WASF2 and ZNF444.
  • 46. The method of claim 38, wherein step (b) comprises measuring the expression levels of a plurality of genes, each gene being known to be differentially expressed between corresponding synchronized cells derived from AD patients and those derived from NDS patients.
  • 47. The method of claim 46, wherein the plurality of genes is selected from the group consisting of at least two genes, at least five genes, at least 20 genes, at least 100 genes, and at least 1,000 genes.
  • 48. The method of claim 47, wherein each gene of the plurality of genes is known to be differentially expressed by at least 50% between corresponding synchronized cells derived from AD patients and those derived from NDS patients.
  • 49. The method of claim 48, wherein each gene of the plurality of genes is known to be differentially expressed by at least 100% between corresponding synchronized cells derived from AD patients and those derived from NDS patients.
  • 50. The method of claim 49, wherein the plurality of genes comprises two or more genes selected from the group consisting of AC004057.1, ACP6, ADAM20, RPL5, SHISA5, SNHG14, WASF2 and ZNF444.
  • 51. The method of claim 38, wherein measuring the expression level of a gene comprises measuring the number of that gene's RNA transcripts per number of total transcripts.
