Chronic infection with hepatitis B virus (HBV) is a major risk factor for the development of hepatocellular carcinoma (HCC). The HBV encoded oncoprotein, HBx, alters the expression of host genes and the activity of multiple signal transduction pathways. Short chain fatty acids (SCFAs) having anti-inflammatory and anti-neoplastic properties can block the progression of chronic liver disease (CLD) to HCC.
Each patent, publication, and non-patent literature cited in the application is hereby incorporated by reference in its entirety as if each was incorporated by reference individually.

Liver cancer is the sixth most commonly diagnosed and second most lethal cancer worldwide. HCC accounts for about 80% of global primary liver cancer diagnoses. The incidence of HCC continues to increase, with rates tripling in the U.S. over the past twenty years. Chronic infection with HBV is a major risk factor for HCC. HBV has infected roughly 2 billion people worldwide, and among these, an estimated 250 million become carriers who are at increased risk for the development of hepatitis, cirrhosis, and HCC. In the U.S., the two-year survival rate from the time of diagnosis is less than 50%, and 5 year survival rate is only 8.9%, thereby highlighting the urgent need for more effective therapeutic options.
Chronic infection with hepatitis B virus (HBV) is a major risk factor for the development of hepatocellular carcinoma (HCC). The HBV-encoded oncoprotein, HBx, alters the expression of host genes and the activity of multiple signal transduction pathways. HBV encoded HBx can contribute centrally to the development of HCC.
Recurrent cycles of cell death and regeneration in CLD are associated with increased integration of the HBx gene into host DNA, and production of functional HBx, thereby leading to alterations of host gene expression, chromosomal instability, and altered signaling pathways crucial to cell survival, inflammation, angiogenesis, and immune responses. Among the signaling pathways altered by HBx, the PI3K, Ras, and NF-κB signaling pathways promote cell survival and growth. Aberrant activation of PI3K, PDGF, VEGF, Ras, and NF-κB by HBx can lead to HCC initiation and progression. HBx can also alter host gene expression through epigenetic regulation, by stimulating histone deacetylases (HDACs) and DNA methyltransferases (DNMTs), HBx is capable of silencing tumor suppressors and activating host oncogenes to promote carcinogenesis.
HCC change can alter the composition of the gut microbiome. This change can correspond to changes in the levels and ratios of pro-inflammatory and anti-inflammatory metabolites in the gut. SCFAs are produced by the anaerobic fermentation of dietary fiber carried out by gut microorganisms. SCFAs regulate cell growth and differentiation, prevent or lessen the likelihood of inflammation, inhibit cell proliferation, and induce apoptosis in cancer cells. SCFAs can oppose the actions of HBx on many of the same molecules and pathways that HBx exploits in carcinogenesis. For example, SCFAs can reduce cell proliferation by inhibiting histone deacetylases (HDACi), whereas HBx stimulates the activity of selected HDACs. Thus, SCFAs can reverse the epigenetic effects of HBx on chromatin structure. SCFAs inhibit pro-inflammatory NF-κB signaling, while HBx stimulates NFκKB and associated inflammation. Specifically, HBx expression and activity are increased in an oxidative environment characteristic of inflammation. Further, the intensity and distribution of intrahepatic HBx expression correlates with the severity of CLD, thereby suggesting that a chronic inflammatory environment potentiates the actions of HBx.

SCFAs were used to treat colitis-associated colorectal cancer, which develops on a background of chronic inflammation, as does HCC from CLD. Thus, experiments were designed to test the hypothesis that SCFAs delays the development of dysplastic nodules and/or HCC in an HBx transgenic (HBxTg) mouse model that closely recapitulates many steps in the pathogenesis of CLD and HCC seen in human HBV carriers. To determine the impact of SCFAs on the development of dysplastic nodules, HBxTg mice were treated with SCFAs or PBS from 6-9 months of age (henceforth referred to as ‘9-month group’). To determine the impact of SCFAs upon HCC development, an additional group of mice was treated with SCFAs or PBS from 9-12 months of age (henceforth referred to as ‘12-month group’).
At the end of treatment, livers from 9-month and 12-month groups were evaluated for histopathology and 12-month group livers further analyzed by proteomics (
TABLE 1 shows liver histopathology in 9-month old mice after three months of treatment. TABLE 2 shows liver histopathology in 12-month old mice after three months of treatment. Livers were assessed for hepatitis, steatosis, dysplasia, and HCC in 5 different sections from different parts of each lobe. At this age, HCC nodules were not visible. Plus sign (+) indicates the presence of disease stage and the minus sign (−) indicates absence. The number of lesions were counted and listed in parentheses.
Further, SCFAs reduced the number of mice that developed HCC compared to control mice in the 12-month group (TABLE 3, P<0.001). TABLE 3 shows tumors in SCFA-treated and control mice at 9-months and 12-months of age.
Among those mice that developed tumors, SCFA-treated mice had predominantly small sized tumors compared to predominately large tumors that developed in PBS treated mice (
When liver sections from 9-month and 12-month old mice were examined for histopathology by light microscopy, HCC was only present in the livers of mice that also had other lesions characteristic of CLD (
Since SCFAs were able to delay tumor development in the HBxTg mice, additional experiments were designed to evaluate whether SCFAs had an impact on human HCC cell viability. When previously described Hep3Bx and Huh7x human hepatoma cell lines constitutively expressing HBx were treated with SCFAs, cell viability decreased in a dose-dependent manner over a 24-hour period. In contrast, the viability of primary human hepatocytes was unaffected by SCFA treatment at the same doses and time-period (P<0.01;
-), and Hep3Bx (
). All measurements were performed in triplicate. Results are expressed as the percent viability of SCFA-treated compared to PBS-treated cells. * indicates p<0.01. SCFAs, short chain fatty acids.
Mass spectrometry-based proteomics was performed on SCFA-treated and control 12-month old HBxTg mouse livers to determine the effect of SCFAs on protein expression in biological processes and signaling pathways at the age when tumors appear. Accordingly, three biological replicates were included in each group analyzed. Tissue from different lobes of the liver were taken from each sample. Although these may have included microscopic tumors, the vast majority of the cells in these samples were non-tumor. Among the more than 3,000 proteins identified, 222 proteins were differentially expressed in the 12-month group. Differentially expressed proteins include those detected in SCFA compared to PBS-treated groups at levels significantly different from one another (P<0.05), as well as proteins detected in the majority or all samples in one group and not detected in any samples of the comparison group. The mass spectrometer used in this study, Q exactive, is capable of detecting proteins present in as little as 1 ng of sample, making it a very sensitive mass spectrometer with a low limit of detection.
Differentially expressed proteins in livers of SCFA-treated compared to PBS-treated mice were arranged by their GO biological processes (
Among the 14 differentially expressed genes that mediate protein transport, 13 of them were detectable in the control livers, but were below the limit of detection in the SCFA-treated samples. This observation suggests that SCFAs down-regulate protein transport (TABLE 4), including down-regulated expression of proteins involved in trafficking between the Golgi and endosome (MON), a protein regulating exocytosis (exocyst complex components 2 and 5), nuclear import and export (importin-5, exportin-7, importin subunit α-1, nuclear pore complex protein Nup98), and NF-KB signaling (ELKS/Rab6 interacting CAST) family member.
TABLE 4 shows differentially expressed proteins associated with biological processes that are altered by SCFAs compared to PBS in the 12-month old liver
1+, proteins that are strongly up-regulated by SCFA treatment and undetectable in PBS controls; −, proteins that are strongly up-regulated in PBS controls and undetectable in SCFA treated livers. Proteins with numerical values represent the fold change in SCFA treated compared to PBS treated mice.
Further, 10 proteins involved in apoptotic pathways were differentially expressed after SCFA treatment. This observation suggests that SCFAs may promote apoptosis (via increased expression of STE20-like ser/thr kinase, ATP-dependent RNA helicase DDX47, and the tumor suppressor DAB2), or protect from apoptosis (via up-regulation of the baculoviral IAP repeat-containing protein 6, down regulation of β-catenin-like protein 1, and the tumor suppressor protein prune homolog). In transcriptional regulation, SCFAs are known transcriptional regulators via histone deacetylase inhibition, and treatment results in the up-regulated expression of transcription elongation factor A protein 3, ENY2, actin-like protein 6A, and leucine-rich repeat flightless-interacting protein 1 (a transcriptional repressor), as well as down-regulated expression of β-arrestin-1, TFIID subunit 5, and cryptochrome-1.
Transcription may also be altered by differential expression of the chromatin remodeling proteins SWI/SNF complex subunit of SMARCC2 and nucleoplasmin-3. The expression of 6 mitochondrial proteins are also altered, being detectable in PBS control livers but undetectable in the livers of SCFA-treated mice. The expression of smaller numbers of proteins are also altered in a variety of other pathways (
Pathway analysis of 12-month old livers showed that SCFA treatment was associated with the downregulation of pathways known to be activated by HBx in hepatocarcinogenesis. These pathways include inflammation, PI3K, PDGF, FGF, IGF, EGF, Wnt, VEGF, and Ras (
The results above showed that SCFA treatment was associated with a decrease in the size and appearance of HCC nodules in some mice, and smaller tumors in others (
The Ras/Raf/MEK/ERK signaling cascade drives cell proliferation, differentiation, apoptosis, and tumorigenesis, and is activated in 50-100% of human HCCs. HBx activates Ras by promoting Shc-Grb2-Sos complex formation. Dab2 inhibits Ras activation by competitively blocking the formation of this complex. To validate the results of the proteomics with regard to the Ras pathway, IHC was performed. For HBx, many of the SCFA-treated and placebo-treated mice showed diffuse, lobular and scattered tissue staining in the nuclear and cytoplasmic compartments of cells, although the differences were not statistically significant. However, the intensity of HBx staining decreased in SCFA-treated mice compared to controls (compare
Ras is a small GTPase that cycles between the active, GTP-bound form, and the inactive, GDP-bound form. Experiments were then designed to determine the levels of the active form of Ras (Ras-GTP) in the 12-month old SCFA-fed and PBS-fed livers using a GST-pulldown assay. SCFA-treated HBxTg mouse livers showed a 4-fold decrease in expression of Ras-GTP compared to control samples (
Experiments were designed to identify changes occurring in the liver of HBxTg mice at the time when HCC nodules develop. SCFAs significantly reduced the number of mice that developed dysplasia by 9 months of age (TABLE 3). In 12-month old mice, treatment reduced the number of mice that developed dysplasia and HCC (TABLE 3). Unexpectedly, the incidence of steatosis was higher in both treated groups compared to controls, although these differences were not statistically significant. This may be due to a higher intake of fatty acids in the treated group, as previously reported. The 12-month group treated with SCFAs had smaller tumors than control mice (
To distinguish the nature of these changes in signaling pathways and patterns of gene expression that underlie the effects of SCFAs, proteomics was conducted in multiple liver samples harvested from 12-month old mice. The results showed differential expression of many proteins in a variety of biological processes (
In addition, NF-κB, which is constitutively activated by HBx and contributes importantly to the pathogenesis of HCC, is epigenetically down-regulated by SCFAs, especially butyrate. Among the downregulated cancer-related pathways herein, Ras, PI3K, VEGF, FGF, and EGF are all activated by HBx in HCC, and all crosstalk with NF-κB, thereby suggesting that NF-κB inhibition may also occur. HBx protects infected cells from apoptosis by promoting activity of the PI3K and Ras pathways. This deregulation was found to promote HCC progression through unrestrained cell proliferation, invasion, and metastasis. Alternations in other pathways involving angiogenesis (VEGF signaling), cell death (apoptosis signaling), immune mediated destruction (T cell activity), sustained proliferative signaling (IGF, Ras, and PDGF), tumor promoting inflammation (chemokine and cytokine signaling), as well as invasion and metastasis (integrin signaling), all of which are down-regulated by SCFAs, are hallmarks of cancer that can underlie the delay in the multiple steps that ultimately result in the development of HCC.
Previously, HBx was shown to synergize with Kras to promote the formation and progression of HCC. This relationship also led to the deregulation of Akt, TGF-β, and β-catenin, among other proteins. Proteomic analysis of HBV-infected tissue confirmed HBx increases oxidative stress through interaction with HIF-1α, a pathway that was also demonstrated to be altered in the proteomic analysis herein. Further analysis of HBV-HCC tissue compared to adjacent non-tumor tissue showed altered expression of β-catenin-related proteins, NF-κB signaling components, ribosomal subunits, ubiquitin-related proteins, respiratory complex and metabolism-related protein, which corroborates changes also detected in the present study. This data presented herein establish that some of the proteins and pathways altered by HBx in the pathogenesis of HCC are reversed by treatment with SCFAs.
Treatment with the multi-kinase inhibitor, sorafenib, and related compounds, has been the standard of care for patients with late HCC. Specifically, the inhibition of the PI3K, PDGF, VEGF, IGF, TGF-β, and Ras pathways by sorafenib is largely regarded as responsible for the drug's chemotherapeutic effect. One problem limiting the efficacy of sorafenib may be that treatment is provided to patients with advanced HCC, and if many of the critical changes leading to cancer already occur prior to the development of tumors, earlier intervention may have prophylactic value. Because SCFAs had no effect on the viability of normal hepatocytes (
Given that SCFAs reduce the incidence of HCC in 12-month old treated livers, and that the Ras signaling pathway is both stimulated by HBx and is commonly activated in HCC, additional work was carried out to validate that the activity and differential expression of Ras pathway components that were differentially expressed by proteomics. The results in
The epigenetic silencing of Dab2 has been investigated in other human cancers. Treatment with Trichostatin A (TSA), a well-known HDACi, restored Dab2 expression in nasopharyngeal carcinoma, squamous cell carcinoma, and transitional carcinoma cells. This result indicates that HDAC-mediated chromatin modulation can play a role in Dab2 downregulation. SCFAs may be able to recover expression of epigenetically silenced genes in several ways. SCFAs may block HBx itself thus preventing it from mediating its alterations, as butyrate has been shown to block HBx expression by inhibiting the HDAC, SIRT-1. Butyrate has also been shown to inhibit the expression of HBx in HepG2.2.15 cells, which has also been observed in vivo. At the molecular level, SCFAs may render HDACs ineffective by competitively binding to their active sites, thus preventing the silencing of tumor suppressors. Decreased HBx expression in the liver of SCFA-treated mice (
A. Short chain fatty acids (SCFAs): SCFAs were purchased and used without further purification. The SCFAs were sodium salts of butyrate, propionate, and acetate.
B. Mice and treatments: In HBxTg mice (C57B1/6×DBA), hepatitis and steatosis develops in animals by 6 months of age, dysplasia by 9 months, and HCC nodules by 12 months. Sibling littermates, consisting of 6-month and 9-month old mice of both genders, were treated five days per week during daylight hours with SCFAs or phosphate buffered saline (PBS) by oral gavage for three months. Concentrations of each SCFA were 40 mM of butyrate, 67.5 mM of acetate, and 25.9 mM of propionate. After three months of treatment, livers were removed and then examined histologically. Tumor diameters were measured using a caliper for small (<0.5 cm), medium (0.5-1.0 cm), and large (>1 cm) nodules. Liver samples from three mice in the 12-month old group were prepared for proteomics (see below).
Controls were sibling littermates. All mice were fed the same diet and given water ad libitum. Mice were not fasted before treatment. Treatment was delivered during the light cycle at approximately the same time each day. Mice were housed in autoclaved cages with Bed-o'cob® and domes for enrichment. After three months of treatment, mice were anesthetized with a ketamine/xylazine cocktail and then perfused with PBS.
C. Immunohistochemistry: Immunohistochemistry (IHC) analyses were performed using paraffin-embedded sections of tissue samples. Primary antibodies were anti-HBx (anti-99), as well as rabbit polyclonal antibodies against Dab2 and Shoc2.
Livers from HBxTg mice were removed, fixed in formalin, and embedded in paraffin. 5-μm thick tissue slices were prepared from these paraffin blocks. For immunohistochemistry (IHC), slides were deparaffinized, dehydrated, incubated for 30 minutes in Unitrieve antigen retrieval solution, heated to 60° C., and stained using the UltraVision® detection system. Normal mouse immunoglobulin G (IgG) was used as a control for anti-Dab2 while pre-bleed rabbit serum from the same animal immunized to produce anti-99 (anti-HBx peptide antibodies) was used as a control for HBx IHC. For Dab2 staining, rabbit polyclonal antibodies were used, and normal rabbit IgG was used as control. Antibody dilutions were used as recommended by the manufacturer. IHC results were recorded as + (<20% positive cells), ++ (20-70% positive cells), and +++ (>70% positive cells). IHC was also evaluated at the cellular level as scattered, (individual cells positive), lobular (groups of positive cells), or diffuse (most cells in a section positive). Subcellular localization for IHC was also assessed as membranous (M), nuclear (N), or cytoplasmic (C). Liver histopathology was evaluated using hematoxylin and eosin staining. Slides were evaluated independently by two investigators.
D. SDS/PAGE and Western Blotting: Protein lysates were prepared from snap frozen liver tissue from 12-month old control and SCFA-treated HBxTg mouse liver samples. Previously snap frozen liver tissues were homogenized in lysis buffer with protease inhibitor cocktail. Cell debris was removed by centrifugation twice at 14,000 g for 15 minutes. Protein extracts from cells were prepared using the same lysis buffer. For western blotting (WB), 100 μg of protein extracts from liver tissues were separated by SDS-polyacrylamide gel electrophoresis and transferred to nitrocellulose membranes. Membranes were incubated with anti-Dab2 or anti-Shoc2, and anti-β-actin. The blots were developed using the Odyssey ® western blotting kit. Secondary antibodies were IRDye® goat anti-mouse for β-actin detection or goat anti-rabbit IgG for Dab2 and Shoc2. Visualization was performed by Odyssey® Fc imaging system and quantification by Image Studio® software.
E. RAS Activity assay: A Ras activation assay was performed on control and SCFA-treated HBxTg mouse liver samples to isolate GTP bound Ras according to manufacturer's instructions. Once isolated, the samples were separated by SDS-PAGE and transferred to nitrocellulose membranes. Membranes were incubated with anti-ras and secondary antibody IRDye® goat anti-rabbit IgG. The blots were developed using the Odyssey® western blotting kit. Blots were visualized using Odyssey® Fc imaging system and quantified by Image Studio® software.
F. Cell culture: Huh7 and Hep3B cells were stably transduced with HBx gene by recombinant retroviruses (referred to as Huh7x and Hep3Bx, respectively) and cultured without the selection of individual clones as previously described. Primary human hepatocytes were purchased from Zen-Bio, Inc. and cultured according to manufacturer's instructions.
G. Cell viability and treatment: Cells were plated in 96 well plates in complete DMEM and incubated in 5% CO2 overnight. Treatment consisted of different concentrations of SCFAs (0, 1, 5, and 10 mM) for 24 hours. Cell survival was then determined in triplicate using the MTS assay according to manufacturer's instructions.
H. Proteomics and data analysis: Liver tissues from 12-month old control (n=3) and SCFA-treated (n=3) HBxTg mice were homogenized and extracted proteins were digested. Peptides were acidified and loaded onto an activated in-house-made cation stage tip, purified and eluted into three fractions. Mass spectrometry analysis was performed on these fractions. Differentially altered proteins were organized into functional pathways using the PANTHER (protein analysis through evolutionary relationships) classification system.
Samples were centrifuged at 14,000 g for 10 minutes. After protein concentration was determined using the Bradford assay, 100 μg protein was digested with the enzyme trypsin. Samples were fractionated and desalted according to in-StageTip processing protocol.
Label-free proteomic analysis was performed independently on these fractions from each mouse in each group. Peptide mixtures were fractionated by ion exchange chromatography and then identified by Q Exactive® mass spectroscopy using MaxQuant® software and further analyzed by PANTHER. Electrospray ionization (ESI) was delivered with an emitter (ID 30 μM, 40 mm length) at a spray voltage of −1800 V. MS/MS fragmentation was performed on the ten most abundant ions in each spectrum using collision-induced dissociation with dynamic exclusion (excluded for 10.0 s after one spectrum), with automatic switching between MS and MS/MS modes. The peptide false discovery rate (FDR) was 0.01, protein FDR 0.01, minimum peptide length was 7 amino acids, and the minimum razor and unique peptides was: 1, min. The generated peak list was processed through the Andromeda® software and searched against the SwissProt mouse database (release 2018_01; 16,950 sequences). Andromeda search parameters were set as Mus musculus (species); trypsin (enzyme); carbamidomethyl (fixed modification) on Cys; (variable modification), methionine oxidation and acetyl (protein N-term); 7 ppm mass tolerance for precursor peptide ions and 20 ppm mass tolerance for product ions. Data were filtered at 1% protein and peptide spectrum matches (PSMs) FDR.
I. Statistics: All data were analyzed using Excel® or GraphPad® software and further statistical analyses were performed as outlined below.
For proteomics, a t-test was performed on quantified proteins on select proteins with low variance within a group and on proteins that were differentially expressed to statistical significance between groups. Those proteins that were differentially expressed (greater than two-fold difference in magnitude compared with control mice and P<0.05) were selected for PANTHER pathway analysis. Additionally, those proteins that were detected in the majority or all samples from one group and no samples of the comparison group were selected for pathway analysis and literature searches.
Chi square analysis was used to determine significance between the percentage of treated vs. control HBxTg mouse livers that developed dysplasia and HCC. The Student's t test was used to evaluate significance in dysplastic nodule development in 9-month old treated vs control HBxTg mice as well as tumor development in 12-month old treated vs control HBxTg mice. The difference in staining intensity of Dab2 between treated vs controls was evaluated by chi square analysis. The difference in cell viability in cell lines was determined by Student's t test. Statistical significance was considered when P<0.05.
HBx transgenic mice (C57B1/6×DBA) are created and modified such that the mice develop hepatitis and steatosis by 6 months of age, dysplasia by 9 months of age, and HCC nodules by 12 months of age. Sibling littermates consisting of 6-month and 9-month old mice of both genders are treated 7 days per week during daylight hours with a Formulation 1 (40 mM butyrate, and 25.9 mM of propionate, and 9 mM Mg(OH)2) or treated with phosphate buffered saline (PBS). Formulation 1 or PBS are administered by adding Formulation 1 or PBS to the drinking water for three months. Water is changed daily with fresh Formulation 1 or PBS samples. Each group of mice consist of 10 mice with approximately equal numbers of male and female mice.
After three months of treatment with Formulation 1 (group 1) or placebo (group 2) from 6-9 months of age; or three months of treatment with Formulation 1 (group 3) or placebo (group 4) from 9-12 months of age; mice are bled out, euthanized, and livers are removed for further analyses. For additional experiments, mice are treated for 9 months (ages 3-12 months of age) with Formulation 1 (group 5) or PBS (group 6). Blood samples are screened for pro-inflammatory and anti-inflammatory markers and for the frequency of CD8+ T cells and FoxP3+ T cells by flow cytometry. HBx expression is assessed in the livers of Formulation 1 and PBS treated mice.
A total of 100 patients with a median age of 60 are recruited. The patients have ongoing HBV infections and associated liver inflammation and/or cirrhosis and no contraindication for butyrate. The patients are dosed with a formulation comprising 1 g sodium butyrate, 100 mg sodium propionate, and 0.0055 mg magnesium hydroxide three times daily or given placebo and included in a screening program for hepatocellular carcinoma (HCC). The subjects are followed for a median of 5 years. Just prior to treatment, patients are screened for ALT/AST, GGT; liver stiffness by fibroscan; pro-inflammatory and anti-inflammatory cytokines in blood (TNFalpha, IFNgamma, IL-2, IL-4, IL5-IL-10); and HBV markers (HBeAg, anti-HBe, and HBV DNA). The screenings are repeated yearly until completion of the study. Patients are analyzed by multivariate analysis for incidence of chronic liver disease (hepatitis and fibrosis), liver cancer, chronic liver disease related death (usually from cirrhosis), or transplantation in the treated and untreated cohorts.
