Embodiments described herein provide for uses of grape products, including, but not limited to Chardonnay grape products.
Nonalcoholic fatty liver disease (NAFLD) is recognized as a significant public health problem. Prevalence of NAFLD is 20% to 30% of the general population of Western countries. NAFLD ranges from steatosis (simple fatty liver) to nonalcoholic steatohepatitis (NASH), a condition that increases liver-related morbidity and mortality. Excessive hepatic lipid accumulation, oxidative and endoplasmic reticulum (ER) stress, and insulin resistance are the major manifestations of the progression of this disease. Without being bound to any particular theory, NAFLD can be caused, for example, by excessive hepatic lipid accumulation followed by increased oxidative stress and inflammation results in liver damage. NAFLD is a continuing problem. Embodiments described herein provide for solutions to these problems and others.

Embodiments described herein relate to uses of grape products. In some embodiments, the grape product is a Chardonnay grape product. Other grape products are also described herein.
In some embodiments, grape product is a grape seed product. In some embodiments, the seed products contain the defatted portion of seed (e.g. grape seed), such as pomace meal, pomace flour, seed meal, or, in some embodiments, seed flour. In some embodiments, the seed product includes the contents of defatted seeds that are not extractable by an organic solvent, e.g., are not extractable by ethanol and/or methanol. In some embodiments, the seed product is prepared from seeds having an epicatechin content of at least 600 mg of epicatechin per 100 g of seeds or an epicatechin content of at least 700 mg of epicatechin per 100 g of seeds. In some embodiments, the epicatechin content ranges from 600-800 mg/100 g of seeds or from 650-800 mg/100 g of seeds.
As described herein, the grape product can be whole pomace or a portion thereof, grape skin product, grape seed product, or any combination thereof, or any extract thereof. Each of the products or extracts thereof can be used alone or in any combination with one another. The products or extracts can be derived from Chardonnay grapes, Cabernet Sauvignon grapes, Pinot Noir grape products, Sauvignon Blanc grape products, White Riesling grape products, and the like, or any combination thereof. In some embodiments, the grape is a grape grown in a coastal region. In some embodiments, the grape is a grape grown in a Winkler region climate type I, II, III, IV or V.
For the avoidance of doubt, a grape product is not a whole intact grape, but rather is a grape that has been processed. Examples of grape products are described herein.
As used herein, “seed meal” is ground whole seeds and “seed flour” is ground seed after the oil has been extracted. Seed flour may be obtained using the “cold press”, “hot press” and solvent extraction processes as are known in the art to extract the oil from seeds yielding defatted seed flour. The meal or flour can be dried to the desired moisture content using conventional drying techniques suitable for drying food products.
The dried meal or flour can be further ground under ambient temperature conditions to form seed powder having free-flowing particles. In some embodiments, the free-flowing particles can range from a size not exceeding 841 microns (20 mesh) to a size not exceeding 37 microns (400 mesh). In certain embodiments, the size does not exceed 20 mesh, 40 mesh, 60 mesh, 80 mesh, 100 mesh, 200 mesh, 300 mesh, or 400 mesh.
In some embodiments, seed flour is made by separating and drying grape seeds, for example from the pomace produced after grapes are pressed to produce grape juice (e.g., to make wine). The grape seeds can be “cold-pressed” to defat them (producing seed oil as a byproduct). Grape seed flours are milled from the press cake after the oil is expelled. In one embodiment, after juicing the grape the seed is separated from the skins, cleaned, mechanically defatted, finely milled and sifted to create an 100-80 mesh (149-177 micron) flowable powder.
Seed flour can also be purchased from a variety of sources. For example, certain types of grape seed flour can be purchased from Aprés Vin (Yakima, Washington), Botanical Oil Innovations (Spooner, Wisconsin) or Fruitsmart, Inc. (Grandview, Washington). The seed flour can sometimes be purchased as an 80 mesh flowable powder. In some embodiments, this is product is further milled and sifted to produce a flour with a smaller particle size.
In some embodiments, skins, stems and leaves (the remainder of pomace) are removed from the seeds prior to pressing. Removal of the skins, stems, and leaves allows for optimal oil pressing.
In some embodiments, the grape product is whole grape pomace or a portion thereof including fractions of seed, skin, leaf, stem, and the like. These fractions can also be present in a mixture of different ratios.
“Seed extract” can be made by solvent extraction of grape seeds with a suitable solvent, such as ethanol or methanol. For example, a grape seed extract, such as, but not limited to Chardonnay seed extract, can be made using a 40% ethanol solution as the extraction solvent. The extraction process, in addition to the extract containing the solvent soluble components, also produces a residue of non-soluble solids. The seed extract can then be combined with other grape products described herein or be used alone. Other extracts of the pomace can also be used. Extracts of skins can also be used or prepared.
In addition to the grape seed products disclosed herein other grape products can also be used in the methods. The other grape seed products can be used in the place of, or in combination with, the Chardonnay seed products. Examples of other grape seed products include, but are not limited to, Syrah grape seed products, Cabernet Sauvignon grape seed products, Pinot Noir grape seed products, Sauvignon Blanc grape seed products, White Riesling grape seed products, and the like.
The seed products can be included in a variety of food products, such as nutritional beverages (e.g., nutritional shakes), baked goods (e.g., cookies, brownies, cake, breads, biscuits, crackers), puddings, confections (i.e., candy), snack foods (e.g., pretzels), ice cream, frozen confections and novelties, or non-baked, extruded food products such as bars, including health or energy bars. The Chardonnay seed product can also be provided as a nutritional supplement, either in tablet or capsule form, or as a powder for use as a nutritional food or beverage additive.
In some embodiments, the seed product can be blended with other dry food materials for use in the preparation of food products enriched with seed products. Dry food materials include, for example, dry starch-containing materials, dry protein-containing materials or combinations thereof. Suitable starch-containing materials may be derived from, for example, rice, corn, soybeans, hemp, sunflower, canola, wheat, oats, rye, potato, or any combination thereof. Suitable dry protein-containing materials may be derived from for example, meat, milk, fish or any combination thereof. For baking applications, the seed product is suitable used in an amount ranging from 3% to 15% of the dry food material (e.g., white or whole wheat flour). The dry food may optionally also include additional ingredients such as vitamins, mineral fortifiers, salts, colors, flavors, flavor enhancers or sweeteners.
Seed products can be incorporated into beverages, processed meats, frozen desserts, confectionery products, dairy-type products, sauce compositions, and cereal grain products.

Alternatively, the active ingredient can be in powder form for constitution with a suitable vehicle, for example, sterile pyrogen-free water, before use.
For administration by injection, the compositions can be administered in solution in a sterile aqueous vehicle which may also contain other solutes such as buffers or preservatives as well as sufficient quantities of pharmaceutically acceptable salts or of glucose to make the solution isotonic. In some embodiments, the pharmaceutical compositions may be formulated with a pharmaceutically acceptable carrier to provide sterile solutions or suspensions for injectable administration. In particular, injectables can be prepared in conventional forms, either as liquid solutions or suspensions, solid forms suitable for solution or suspensions in liquid prior to injection or as emulsions. Suitable excipients are, for example, water, saline, dextrose, mannitol, lactose, lecithin, albumin, sodium glutamate, cysteine hydrochloride, or the like. In addition, if desired, the injectable pharmaceutical compositions may contain minor amounts of nontoxic auxiliary substances, such as wetting agents, pH buffering agents, and the like. If desired, absorption enhancing preparations (e.g., liposomes) may be utilized. Suitable pharmaceutical carriers are described in “Remington's pharmaceutical Sciences” by E. W. Martin.
For administration by inhalation, the compositions may be conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebulizer, with the use of a suitable propellant, for example, dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide, or other suitable gas. In the case of a pressurized aerosol, the dosage unit can be determined by providing a valve to deliver a metered amount. Capsules and cartridges of, for example, gelatin for use in an inhaler or insufflator can be formulated containing a powder mix of the compound and a suitable powder base, for example, lactose or starch. For intranasal administration the compositions of the invention may be used, for example, as a liquid spray, as a powder or in the form of drops.
The compositions can also be formulated in rectal compositions, for example, suppositories or retention enemas, for example, containing conventional suppository bases, for example, cocoa butter or other glycerides.
Furthermore, the compositions can be formulated as a depot preparation. Such long-acting formulations can be administered by implantation (for example, subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compounds can be formulated with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.
The compositions can, if desired, be presented in a pack or dispenser device that can contain one or more unit dosage forms containing the active ingredient. The pack can, for example, comprise metal or plastic foil, for example, a blister pack. The pack or dispenser device can be accompanied by instructions for administration.
The compositions prepared according to the methods described herein may be administered to a patient at effective doses, including therapeutically effective doses, to prevent, treat, or control diseases and disorders described herein. They can also be used to restore or maintain a healthy liver as described herein. Pharmaceutical compositions may be administered to a patient in an amount sufficient to elicit an effective maintenance, protective, restorative, or therapeutic response in the patient. An amount adequate to accomplish this is defined as “therapeutically effective dose.” The dose will be determined by the efficacy of the particular composition employed and the condition of the subject, as well as the body weight or surface area of the area to be treated. The size of the dose also will be determined by the existence, nature, and extent of any adverse effects that accompany the administration of a particular compound or vector in a particular subject.
Toxicity and therapeutic efficacy of such compositions can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, for example, by determining the LD50 (the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index and can be expressed as the ratio, LD50/ED50. Compositions that exhibit large therapeutic indices are preferred. While compositions that exhibit toxic side effects can be used, care should be taken to design a delivery system that targets such compounds to the site of affected tissue to minimize potential damage to normal cells and, thereby, reduce side effects.
The data obtained from cell culture assays and animal studies can be used to formulate a dosage range for use in humans. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage can vary within this range depending upon the dosage form employed and the route of administration. For any composition used in the methods described herein, the therapeutically effective dose can be estimated initially, for example, from cell culture assays. A dose can be formulated in animal models to achieve a circulating plasma concentration range that includes the IC50 (the concentration of the test compound that achieves a half-maximal inhibition of symptoms) as determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Levels in plasma can be measured, for example, by high performance liquid chromatography (HPLC). In general, the dose equivalent of a modulator is from about 1 ng/kg to 10 mg/kg for a typical subject or as described elsewhere herein.
The amount and frequency of administration of the compositions will be regulated according to the judgment of the user or attending clinician considering such factors as age, condition and size of the patient as well as severity of the symptoms being treated. An ordinarily skilled physician or veterinarian can readily determine and prescribe the effective amount of the drug required to prevent, counter or arrest the progress of the condition. In general it is contemplated that an effective amount would be from 0.001 mg/kg to 10 mg/kg body weight, and in particular from 0.01 mg/kg to 1 mg/kg body weight or as otherwise described herein. In some embodiments, it is contemplated that an effective amount would be to continuously infuse by intravenous administration from 0.01 micrograms/kg body weight/min to 100 micrograms/kg body weight/min for a period of 12 hours to 14 days. It may be appropriate to administer the required dose as two, three, four or more sub-doses at appropriate intervals throughout the day. Said sub-doses may be formulated as unit dosage forms, for example, containing 0.01 to 500 mg, and in particular 0.1 mg to 200 mg of the composition per unit dosage form.
In some embodiments, the pharmaceutical preparation is in a unit dosage form. In such form, the preparation is subdivided into suitably sized unit doses containing appropriate quantities of the active component, e.g., an effective amount to achieve the desired purpose. The quantity of active compound in a unit dose of preparation may be varied or adjusted from about 0.01 mg to about 1000 mg, from about 0.01 mg to about 750 mg, from about 0.01 mg to about 500 mg, or from about 0.01 mg to about 250 mg, according to the particular application. The actual dosage employed may be varied depending upon the requirements of the patient and the severity of the condition being treated. Determination of the proper dosage regimen for a particular situation is within the skill of the art. For convenience, the total dosage may be divided and administered in portions during the day as required.

Diet-induced (DIO) hamsters were fed a high fat (HF) diet for 10 weeks. Animals that exhibited low glucose tolerance and were in the heaviest category were given the various treatments. Animals were fed diets containing partially defatted Chardonnay flavonoid-rich wine grape seed flour (ChrSd), commercial extracts, or laboratory produced ethanolic extracts of ChrSd for 10 and 20 weeks, respectively. Half were sacrificed and examined for signs of hepatic dysfunction at 10 weeks and the other half examined after 20 weeks. Animals on treatments benefited. Animals on ChrSd whole flour treatments showed no signs of ectopic fat in the liver, whereas those on the HF Control diet showed extensive fat deposition in the liver. Livers of animals under various treatments weighed significantly less than those on the HF Control. Blood lipid profiles of animals on various grape seed treatments showed improved blood lipid profiles. Accordingly, ChrSd can be used to maintain a healthy blood lipid profile, such as when the animal is subjected to a high fat diet.
Diet-induced obese (DIO) mice were fed high-fat (HF) diets containing either partially defatted flavonoid-rich Chardonnay grape seed flour (ChrSd) or microcrystalline cellulose (MCC, control) for 5 weeks in order to determine whether ChrSd improved insulin resistance and the pathogenesis of hepatic steatosis. The 2-h insulin and glucose areas under the curves were significantly lowered by ChrSd, indicating that ChrSd improved insulin sensitivity and glucose metabolism. ChrSd intake also significantly reduced body weight gain, liver and adipose tissue weights, hepatic lipid content, and plasma low-density lipoprotein (LDL)-cholesterol, despite a significant increase in food intake. Exon microarray analysis of hepatic gene expression revealed down-regulation of genes related to triglyceride and ceramide synthesis, immune response, oxidative stress, and inflammation, and up-regulation of genes related to fatty acid oxidation, cholesterol, and bile acid synthesis. Expression of leptin receptor was up-regulated, suggesting enhanced hepatic leptin sensitivity. Pathway analysis of the microarray data revealed that lipid and cholesterol metabolism, and infectious and metabolic disease pathways were differentially regulated by ChrSd. In conclusion, ChrSd ameliorated the effects of a HF diet on weight gain, insulin resistance, and progression of hepatic steatosis in DIO mice via modulation of hepatic expression of genes related to oxidative stress, inflammation, and lipid and cholesterol metabolism.
Animals and Diets. Male C57BL/6J mice were housed individually in an environmentally controlled room (20-22 C, 60% relative humidity, 12-h alternating light/dark cycle). The mice were acclimated and given ad libitum access to water and mouse chow diet (LabDiet 5015, PMI International, Redwood, CA, USA) for 1 week prior to initiation of the experimental diets. Mice were weighed and randomized into two groups of 30 mice each. Mice were fed ad libitum with either mouse chow diet or a HF diet containing 17% of energy as protein, 37% as carbohydrate, and 47% as fat, with 0.1% cholesterol. After 5 weeks, mice were weighed, and diet-induced obese (DIO) mice were identified as those having gained significantly more weight than the chow-fed mice. The DIO mice were then randomized into two groups (n=10 each) and fed ad libitum for 5 weeks with HF diets containing either 10% ChrSd (Sonomaceuticals, LLC/WholeVine Products, Santa Rosa, CA) or 5% microcrystalline cellulose (MCC, control diet; Dyets Inc., Bethlehem, PA) (Table 1). MCC, an insoluble fiber, has little effect on sterol metabolism (Horton, 1994 #56). Chardonnay grape pomace was obtained from coastal vineyards in Sonoma County, California. Seeds from the 2010 vintage were dried using heated air (55-70 C) and separated from skins and stems. The residual press cake was milled to pass through an 85 mesh sieve, after oil had been pressed from the seed. The total flavonoids, total catechins, catechin, and epicatechin contents of ChrSd were 12,000, 1610, 701, and 732 mg/100 g, respectively. Body weights were recorded weekly, and food intake was monitored twice per week. The study protocol, #P-04-02, was approved by the Animal Care and Use Committee, Western Regional Research Center, USDA, Albany, CA, USA.
Plasma and Liver Collection. Mice were feed-deprived for 12 h and anesthetized with isoflurane (Phoenix Pharmaceutical, St. Joseph, MO, USA). Blood was collected by cardiac puncture with syringes previously rinsed with potassium EDTA solution (15% w/v). The plasma was separated after centrifugation at 2,000×g for 30 min at 4 C. Livers and epididymal adipose tissues were collected, weighed, and immediately frozen in liquid nitrogen for later analysis. After freeze-drying, the powdered livers were weighed and mixed with 2 mL of CHCl3/MeOH (2:1), sonicated for 5 min, and then incubated overnight. The samples were centrifuged for 10 min at 1000 rpm, and the supernatant was removed. Another 2 mL of CHCl3/MeOH was added, sonicated, and allowed to stand overnight to extract. Solvent was removed from the combined extracts under nitrogen and the total hepatic total lipid content was determined gravimetrically.
Plasma Lipid Analysis. Plasma lipoprotein cholesterol was determined by size exclusion chromatography. Briefly, high-performance liquid chromatograpy (HPLC) was carried out using an Agilent 1100 HPLC chromatograph with a Superose 6HR HPLC column (Pharmacia LKB Biotechnology, Piscataway, NJ, USA) consisting of a mixing coil (1615-50 Bodman, Aston, PA, USA) in a temperature-controlled water jacket (Aura Industrials, Staten, NY, USA). A Hewlett-Packard HPLC pump (79851-A; Agilent Technologies, Palo Alto, CA, USA) was used to deliver cholesterol reagent (Roche Diagnostics, Indianapolis, IN, USA) at a flow rate of 0.2 mL/min. Bovine cholesterol lipoprotein standards were used to calibrate the signal on the basis of peak areas.
Glucose Tolerance Test (GTT) and Insulin Tolerance Test (ITT). After a 3-h fast, mice were administrated glucose intraperitoneally (2 g/kg body weight), and tail vein blood glucose levels were determined at 0, 15, 30, 60, and 120 min after glucose injection using a OneTouch Ultrameter (LifeScan Inc., Wayne, PA). ITT was performed after mice were administrated insulin intraperitoneally (0.5 U/kg body weight). Glucose levels were determined in tail vein blood at 0, 30, and 60 min after insulin injection using a OneTouch Ultrameter (LifeScan Inc.).
Gene Expression and Exon Microarray Analysis. Total liver RNA was extracted from three biological replicates within each group using a TRIzolplus RNA purification kit (Invitrogen, Life Technologies, Carlsbad, CA, USA). The total RNA quality was determined using a 2100 Bioanalyzer instrument and RNA 6000 Nano LabChip assay (Agilent Technologies, Palo Alto, CA, USA). Total RNA (10 μg) was then used to synthesize one-cycle cDNA (first-strand and second-strand cDNA synthesis) followed by clean-up of double-stranded cDNA, and biotin-labeled cRNA synthesis. The biotin-labeled cRNA was fragmented using One-Cycle Target Labeling and Control reagents (Affymetrix, Santa Clara, CA, USA). Fragmented cRNA samples were hybridized to an Affymetrix GeneChip Mouse exon 1.0 ST array, an expression and exon splicing array containing 1.2 million probe sets, representing 80000 genes. The hybridization signals were acquired and analyzed using the GeneChip Scanner 3000 High-Resolution Scanner (Affymetrix) and the Affymetrix GeneChip Operating Software (GCOS). Analysis of both gene expression and exon alternative splicing from the microarray data was performed using a GeneSpring GX version 11.0 program (Agilent Technologies, Santa Clara, CA). Gene expression was determined to be significant when the change was found to be 1.5-fold and above. The splice index was defined as the log of the ratio of exon-level expression over gene-level expression. A fold change in splice index value ≥2 between treatment and control groups was considered to be differentially spliced. Transcripts with at least one differentially spliced exon were considered to be differentially regulated splicing.
Statistical Analysis. All data were expressed as means±SE. Analysis of variance (ANOVA) was performed using the JMP7 statistical program (SAS Institute, Cary, NC, USA) to examine the effects of treatment on plasma lipid levels, body and tissue weights, total energy intake, and feed efficiency ratio. Significance was defined at P<0.05. Ingenuity Pathways Analysis tool (IPA version 8.7, Ingenuity Systems Inc., Redwood City, CA, USA; http://www.ingenuity.com) was used to analyze the exon microarray data determining biological mechanisms, pathways, and functions from the differentially expressed genes. Right-tailed Fisher's exact test was used to calculate the P value. P values represent the probability that the biological function of each data set, biological function and disease assigned to a particular network for each data set, and the association between the genes in a data set and the corresponding canonical pathway were explained by chance.
ChrSd supplementation of a HF diet for 5 weeks significantly lowered body weight gain of the DIO mice despite a significant increase of total energy intake, resulting in a 72% lower energy efficiency ratio in these mice (Table 2). The ChrSd supplemented diet significantly lowered the liver and epididymal adipose tissue weights by 38% and 35%, respectively, as compared with mice on the control diet (Table 2). Total hepatic lipid content was 43% lower in DIO mice fed ChrSd, as compared to control diet (P<0.05) (Table 2). Dietary ChrSd supplementation significantly lowered peak blood glucose response at 60 min (P<0.05) and the area under the curve (AUC) during a 2-h glucose response (
The comprehensive expression of hepatic genes in DIO mice fed HF diets supplemented with either 5% MCC or 10% ChrSd flour was assessed by exon microarray analysis. A number of genes were differentially expressed in mice fed 10% ChrSd, as compared to those fed 5% MCC (P<0.05, fold change ≥1.5) (Table 3). Among these genes, some were down-regulated and some were up-regulated. Table 3 shows the genes differentially down- and up-regulated by ChrSd, categorized by biological process. Chitinase-like 1(Chi3l1; fold change, −1.5), encoding a protein involved in the activation of nuclear factor-kappaB (NF-κB)-induced kinase activity, involved in inflammation and tissue remodeling, was down-regulated. A gene encoding an enzyme involved in cortiscosteroid biosynthesis (C21-steroid hormone biosynthesis, cytochrome P450, family 21, subfamily a polypeptide 1 (Cyp21a1; fold change, −1.6)) was down-regulated. The expression level of aquaporin 8 (Aqp8; fold change, −1.8), encoding a protein related to canalicular bile acid transport was down-regulated. Genes encoding proteins involved in diacylglycerol and triacylglycerol biosynthetic processes (stearoyl-coenzyme A desaturase 1 [Scd1]; monoacylglycerol O-acyltransferase 1 [Mogat1]) were down-regulated (fold change, −1.6 for both). Expression of odorant binding protein 2A (Lcn13), involved in glucose and lipid metabolism, was down-regulated (fold change, −3.5). Genes involved in immune system processes, including complement factor D (Cfd; fold change, −2.4), cathepsin E (Ctse; fold change, −1.7), orosomucoid 2 (Orm2, fold change, −1.7), retinoic acid receptor-related orphan receptor gamma (Rorc; fold change −1.5), and toll-like receptor 5 (Tlr5; fold change, −2) were down-regulated. Serine palmitoyltransferase, long chain base subunit 3 (Sptlc3; fold change, −1.7), which is involved in sphingolipid metabolism, was down-regulated. Expression of a lipid droplet-associated protein involved in triglyceride metabolic process, perilipin 4 (Plin4; fold change, −3.5), was also down-regulated in mice fed ChrSd, as compared to mice fed MCC. Interferon alpha 9 (Ifna9; fold change, 1.8), a gene encoding a protein related to host immune defense response, was up-regulated. The expression of genes encoding cytochrome P450, family 7, subfamily b, polypeptide 1 (Cyp7b1; fold change, 1.6) and cytochrome P450, family 17, subfamily a, polypeptide 1 (Cyp17a1; fold change, 2.5), related to bile acid metabolism, was up-regulated. Genes involved in cholesterol metabolism, including sterol 14-demethylase (Cyp51; fold change, 5.6), 3-hydroxy-3-methylglutaryl-coenzyme A reductase (Hmgcr; fold change, 2.5), hydroxysteroid (1743) dehydrogenase 7 (Hsd17b7; fold change, 2.8), insulin induced gene 1 (Insig1; fold change, 1.8), sterol-C4-methyl oxidase-like (Sc4 mol; fold change, 4.5), and leptin receptor (Lepr; fold change, 1.6) were up-regulated. The expression level of acyl-CoA synthetase long-chain family member 3 (Acsl3), which is involved in lfatty acid β-oxidation, was up-regulated.
Pathway analysis using the IPA System identified several biological functions and canonical gene pathways that were differentially regulated by ChrSd supplementation (Table 4). When grouped by biological function, the expression levels of genes related to lipid metabolism, hematological disease, and metabolic disease were significantly affected by ChrSd supplementation. In terms of canonical pathways, ChrSd affected the cholesterol biosynthesis superpathway and the zymosterol biosynthetic pathway. Networks involving lipid metabolism and infectious disease were affected by ChrSd supplementation. Insig1, which regulates cholesterol concentration, was identified as a major regulator effects networks (data not shown). Analysis of exon microarray data using the GeneSpring GX11.0 program resulted in the identification of 84 genes with SI>|2.0| in the presence of ChrSd supplementation (data not shown). Further analysis by using RT-PCR needs to be done to confirm the alternative splicing of these genes.
In the current study, exon microarray analysis was used to identify differentially expressed hepatic genes in DIO mice, to provide novel biological insights into the effects of ChrSd supplementation on HF diet-induced hepatic steatosis. We found that, in addition to affecting expression of genes involved in cholesterol, bile acid, and lipid metabolism, dietary ChrSd supplementation significantly affected the hepatic expression of genes involved in C21-steroid metabolism, immune system processes, inflammation, tissue remodeling, and lipid storage. ChrSd supplementation markedly up-regulated hepatic expression of genes related to bile acid and cholesterol synthesis (Cyp17a1, Cyp51, Hmgcr, and Insig1), and fatty acid β-oxidation (Acsl3), whereas it significantly down-regulated the expression of genes related to fatty acid biosynthesis (Scd1, Acot11, and Mlxipl/carbohydrate responsive element-binding protein [ChREBP]), triacylglycerol biosynthesis (Mogat1), oxidative stress (Growth differentiation factor 15, Gdf15), inflammatory and immune processes (Cfd, Chi3l1, Ctse, Orm2, Rorc, and Tlr5), ceramide biosynthesis (Sptlc3), and lipid storage (Plin4). These altered gene expression profiles in hepatic tissue were accompanied by significant reductions in plasma LDL-cholesterol concentration, liver, adipose, and body weights, feed efficiency ratio, and insulin resistance, as compared to the MCC supplemented control group. Notably, ChrSd supplementation lowered the hepatic expression of genes that have a role in obesity including Insig-1, lepR, Neurotrophic tyrosine kinase, receptor, type 2 (Ntrk2), Melanocortin 5 receptor (Mc5r), and Matrix metallopeptidase 7 (Mmp7).
Without being bound by any particular theory, we hypothesize that supplementation with ChrSd containing high amounts of flavonoids can up-regulate genes related to scavenging of reactive oxygen species (ROS) and free radicals, and down-regulate genes related to oxidative stress, inflammation, and fatty acid biosynthesis, leading to improved HF-induced insulin resistance and NAFLD. The suggested mechanisms involved in the antioxidant activity of flavonoids are: 1) free radical scavenging and metal chelating activities; 2) cell-to-cell signaling pathways; and 3) antioxidant enzyme gene expression. The antioxidant activity of grape seed products has been monitored in in vitro. The in vivo biological significance of in vitro activity is not clear because oligomers and larger flavonoids are poorly absorbed, while monomers are rapidly metabolized and cleared from the body. In the present study, expression of stress responsive genes (Gdf15 and ChREBP) was down-regulated following ChrSd supplementation. The hepatic expression of Gdf15, a member of the transforming growth factor (TGF) β superfamily, is related to hepatic steatosis under ER stress. Oxidative stress activates ChREBP, which transcriptionally modulates lipogenic and glycolytic genes, resulting in fatty liver. Taken together, these findings indicated that the flavonoid-rich ChrSd supplement can potentiate antioxidant activity and reduce oxidative stress, resulting in transcriptional down-regulation of ChREBP and lipogenic genes (Scd1, Acot11, Mogat1) in the liver. Despite the down-regulation of stress related genes, the canonical pathway analysis did not identify significant changes in the free radical and ER stress-related signaling pathways in the livers of DIO mice supplemented with ChrSd. Oxidative stress and inflammation are closely interlinked in obesity. However, whether improved oxidative stress and inflammation are secondary to or independent of reduction in hepatic lipid levels is not clear. Additionally, we cannot exclude the possibility that C57BL/6J mice fed a HF diet (47% of energy as fat) for 10 weeks may have already passed through the obesity-related ER stress response and entered the lipogenesis stage. This transition from ER stress to lipogenesis was shown in a previous study of ApoE3L mice on HF diets for 16 weeks; these animals exhibited an early phase hepatic response to the HF diet that was characterized by changes in genes linked to the stress pathways, followed by a late phase involving genes related to lipid accumulation. Likewise, the present study found few ChrSd-induced changes of genes related to free radicals and ER-stress response.
The C57BL/6J mouse has been used extensively to study hepatic steatosis. This animal model shows more susceptibility to HF diet-induced fatty liver disease than BALB/c mice. Genes related to the 26S proteasome and ubiquitin proteasome system in wild type C57BL/6J mice fed HF diets (40% energy as fat) for 15 weeks were up-regulated relative to transgenic mice with lowered proteasome activity, resulting in obesity and hepatic steatosis. In contrast, no significant modulation of genes related to ER-stress and inflammation was observed. In another study, C57BL/6J mice fed a HF diet (60% of energy as fat) developed hepatic steatosis and inflammation after 24 weeks. In the present study, we selected obesity responsive mice by feeding HF diet for 5 weeks and then selecting DIO mice for treatment with HF diets supplemented with either ChrSd or MCC (control) for an additional 5 weeks. The lower degree of free radical scavenging response may be due to the shorter duration of the ChrSd supplementation phase of the study and the lower level of dietary fat, as compared to previous studies showing an oxidative stress response.
Flavonoids have been reported to show immunomodulatory and anti-inflammatory properties, although most of these studies have been conducted in vitro, with very few in vivo or human analyses. In humans, the consumption of 600 mg/day grape seed extract for 4 weeks improved markers of insulin resistance (e.g. blood C-reactive protein [CRP] concentration) and inflammation in type 2 diabetic patients at high risk for cardiovascular disease. In this study, ChrSd supplementation down-regulated hepatic expression of genes related to immune and inflammation processes (Cfd, Chi3l1, Ctse, Orm2, Rorc, Tlr5). Cfd (adipsin) is a serine protease involved as a host response factor in the removal of foreign antigens and pathogens. The Chi3l1 gene is related to activation of NF-κB-induced kinase activity and inflammation. Ctse is an intracellular aspartic proteinase highly expressed in immune-related cells, such as macrophages, and its main role is related to macrophage infiltration, adipogenesis, and hepatic steatosis. Orm2 is expressed in hepatocytes and adipocytes, and secreted into plasma under metabolic and inflammatory stress as an acute phase reactant immunomodulator protein. Rorc regulates Th17 cell differentiation, controlling the production of inflammatory cytokines. Tlr5 is predominantly expressed in epithelial cells of the intestinal mucosa and its expression in liver and adipose tissue is relatively very low. Interestingly, HF diet has been shown to increase Tlr5 expression in mouse epididymal adipose tissue. It is activated by bacterial flagellin proteins and triggers innate immune responses and NF-κB. Although the biological significance of hepatic Tlr5 down-regulation is unclear, ChrSd supplementation may reduce the gut bacterial residence-derived inflammatory response to HF-induced stress. Our previous study suggested that hepatic cholesterol metabolism was influenced by the composition of intestinal microbiota and by intestinal fibroblast growth factor (FGF) 15 gene expression in hamsters following ChrSd supplementation. Collectively, these findings indicate that ChrSd supplementation may prevent HF diet-induced inflammation in the liver via down-regulation of hepatic expression of genes related to immune/inflammatory pathways.
ChrSd supplementation up-regulated hepatic leptin receptor expression by 1.5-fold, as compared with control. Leptin, a hormone produced by adipose tissue, regulates energy intake and expenditure and enhances fatty acid oxidation in liver and muscle. In DIO mice, down-regulation of hepatic leptin receptor expression was observed, suggesting that obesity induces hepatic insensitivity to leptin. Thus, the ChrSd-associated up-regulation in hepatic leptin receptor expression suggested that hepatic leptin sensitivity was improved by this supplement and this could, in part, contribute to reduced hepatic steatosis.
Several studies have suggested that oxidative stress may play an important role in the development of obesity-related complications such as insulin resistance and type 2 diabetes. Consumption of red grape extract improved fructose-induced ER-stress and insulin sensitivity in healthy overweight first-degree relatives of type 2 diabetic patients. Similarly, our study revealed that supplementation with the flavonoid-rich ChrSd significantly improved insulin sensitivity and glucose metabolism, as shown by the 26% and 19% reductions in AUC during 2-h ITT and GTT, respectively, as compared to the control. ChrSd supplementation also significantly lowered the fasting glucose concentration. Additionally, this improved insulin sensitivity was paralleled by down-regulation of hepatic Gdf15 expression. Gdf15 expression has been reported to be induced in response to oxidative stress and inflammation, and its levels are increased in individuals with abdominal obesity, CVD, and insulin resistance. It has been shown that suppression of the hepatic expression of genes related to inflammatory and immune processes was associated with improved liver function of HF-induced fatty liver. On the other hand, lipid derivatives such as ceramides are a critical modulator of cellular stress and their accumulation inhibits insulin signaling. It has been shown that flavonoids influence sphingolipid metabolism and are able to normalize the elevated ceramide content of damaged liver cells. These observations indicated a potential connection between the ChrSd-related down-regulation of hepatic Sptlc3, a gene related to ceramide biosynthesis, and the reduced hepatic lipid content and improved insulin sensitivity reported in the present study. Therefore, improved insulin resistance and reduced hepatic lipid content appeared to be mediated by a reduction in oxidative stress and inflammation in DIO mice supplemented with ChrSd.
Glucokinase (Gck) activation may induce fatty liver in rodents because this enzyme phosphorylates glucose to produce glucose-6-phosphate; this regulates hepatic glucose disposal and stimulates hepatic lipogenesis. Recent studies have shown that Gck overexpression in the liver increases hepatic lipogenesis and circulating lipid concentrations. Furthermore, hepatic Gck expression was associated with hepatic lipogenic gene expression and the lipid content of human liver biopsies. ChrSd supplementation down-regulated hepatic expression of Gck and Gckr (glucokinase regulatory protein) and this may also have contributed to reducing the HF-induced hepatic lipid content.
In summary, it has been demonstrated herein that flavonoid-rich ChrSd, a byproduct of winemaking, improved HF-induced hepatic steatosis, plasma lipid profiles, and weight gain, as well as insulin resistance. These improvements were associated with modulation of the hepatic expression of genes related to bile acid, cholesterol, and fatty acid metabolism, oxidative stress, inflammation, and immune responses. Analysis of exon microarray data revealed that pathways involved in lipid and cholesterol metabolism, and infectious and metabolic disease were differentially regulated by ChrSd. The decreased feed efficiency ratio, and reductions in hepatic lipid content, adipose tissue weight, hepatic ceramide synthesis, and oxidative stress may have contributed to the observed improvement in insulin sensitivity. These results indicate that consumption of flavonoid-rich ChrSd can be beneficial for the prevention and/or treatment of NAFLD and other metabolic diseases due to its reduction of oxidative stress and inflammation, modulation of cholesterol and bile acid synthesis, modulation of lipid metabolism in liver, and amelioration of insulin resistance, as well as promotion of overall liver health.
