[PMID: 36561345 PMCID: PMC9764015 DOI: 10.3389/fphar.2022.1027687] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 11/09/2022] [Indexed: 12/09/2022] Open
Abstract
Objective: Curcumae Rhizoma-Sparganii Rhizoma (CR-SR) is a traditional botanical drug pair that can promote blood circulation, remove blood stasis, and treat tumors in clinics. The aim of the present study was to investigate the therapeutic material basis and potential mechanisms of CR-SR, CR, and SR for the treatment of liver cancer. Method: The chemical profile analyses of CR-SR, CR, and SR were performed by molecular networking and UPLC-LTQ-Orbitrap MSn. The anti-liver cancer activities of CR-SR, CR, and SR were assessed by using a zebrafish xenograft model in vivo for the first time and detected by the HepG2 cell model in vitro. Combining the network analysis and molecular docking, real-time quantitative polymerase chain reaction (RT-qPCR) experiments were undertaken to further explore the mechanisms of CR-SR, CR, and SR for the treatment of liver cancer. Results: In total, 65 components were identified in CR-SR, CR, and SR. Based on the clusters of molecular networking, a total of 12 novel diarylheptanoids were identified from CR-SR and CR. By combining our results with information from the literature, 32 sesquiterpenoids and 21 cyclic dipeptides were identified from CR-SR, CR, and SR. The anti-liver cancer activities were observed in both the drug pair and the single botanical drugs in vitro and in vivo, and the order of activity was CR-SR > CR > SR. They could downregulate the expression of proto-oncogene tyrosine-protein kinase Src (SRC), epidermal growth factor receptor (EGFR), estrogen receptor-α (ESR1), prostaglandin endoperoxide synthase 2 (PTGS2), and amyloid precursor protein (APP). Conclusion: Taken together, the present study provided an experimental basis for the therapeutic material basis and potential molecular mechanisms of CR-SR, CR, and SR. This study provided a novel insight for objective clinical treatment of liver cancer.

Unique Features of Hepatitis B Virus-Related Hepatocellular Carcinoma in Pathogenesis and Clinical Significance. Cancers (Basel) 2021; 13:cancers13102454. [PMID: 34070067 PMCID: PMC8158142 DOI: 10.3390/cancers13102454] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 05/12/2021] [Accepted: 05/14/2021] [Indexed: 02/07/2023] Open
Abstract
Simple Summary Hepatitis B virus (HBV) infection is the major risk factor for hepatocellular carcinoma (HCC). Understanding the unique features for HBV-induced HCC can shed new light on the unmet needs in its early diagnosis and effective therapy. During decades of chronic hepatitis B, hepatocytes undergoing repeated damage and regeneration accumulate genetic changes predisposing to HCC development. In addition to traditional mutations in viral and cellular oncogenes, HBV integration into the cell chromosomes is an alternative genetic change contributing to hepatocarcinogenesis. A striking male dominance in HBV-related HCC further highlights an interaction between androgen sex hormone and viral factors, which contributes to the gender difference via stimulating viral replication and activation of oncogenes preferentially in male patients. Meanwhile, a novel circulating tumor biomarker generated by HBV integration shows great potential for the early diagnosis of HCC. These unique HBV-induced hepatocarcinogenic mechanisms provide new insights for the future development of superior diagnosis and treatment strategies. Abstract Hepatitis B virus (HBV) infection is one of the important risk factors for hepatocellular carcinoma (HCC) worldwide, accounting for around 50% of cases. Chronic hepatitis B infection generates an inflammatory microenvironment, in which hepatocytes undergoing repeated cycles of damage and regeneration accumulate genetic mutations predisposing them to cancer. A striking male dominance in HBV-related HCC highlights the influence of sex hormones which interact with viral factors to influence carcinogenesis. HBV is also considered an oncogenic virus since its X and surface mutant proteins showed tumorigenic activity in mouse models. The other unique mechanism is the insertional mutagenesis by integration of HBV genome into hepatocyte chromosomes to activate oncogenes. HCC survival largely depends on tumor stages at diagnosis and effective treatment. However, early diagnosis by the conventional protein biomarkers achieves limited success. A new biomarker, the circulating virus–host chimera DNA from HBV integration sites in HCC, provides a liquid biopsy approach for monitoring the tumor load in the majority of HBV–HCC patients. To maximize the efficacy of new immunotherapies or molecular target therapies, it requires better classification of HCC based on the tumor microenvironment and specific carcinogenic pathways. An in-depth study may benefit both the diagnosis and treatment of HBV-related HCC.

Abstract
Post-transplant liver fibrosis (PTLF) is a common and severe complication in liver recipients. In this study, we assessed the impact of donor liver genetics on the development of PTLF. A total of 232 patients undergoing liver transplantation were included. Twenty-two single nucleotide polymorphisms (SNPs) associated with liver fibrosis were analyzed. Univariate analysis revealed seven donor SNPs to be associated with PTLF. In a multivariate analysis, independent risk factors of PTLF were genetic variation of donor GRP78 rs430397 (OR = 8.99, p = 0.003), GSTP1 rs1695 (OR = 0.13, p = 0.021), miRNA-196a rs12304647 (OR = 16.01, p =0.001), and TNF-α rs1800630 (OR = 79.78, p = 0.001); blood tacrolimus levels at maintenance > 7 ng/ml (OR =7.48, p <0.001); and post-transplant diabetes mellitus (OR = 7.50, p = 0.001). A predictive model that included donor SNPs showed better prognostic ability for PTLF than a model with only clinical parameters (AUROC: 0.863 vs 0.707, P < 0.001). Given that donor gene SNPs are associated with an increased risk of PTLF, this model integrated with donor gene polymorphisms may help clinicians predict PTLF.

Abstract
OBJECTIVE Acute-on-chronic liver failure (ACLF) is an extreme condition after severe acute exacerbation of chronic hepatitis B; however, the underlying genetic factors involved in its onset and progression are currently unclear. DESIGN We carried out a genome-wide association study among 399 HBV-related ACLFs (cases) and 401 asymptomatic HBV carriers (AsCs, as controls) without antiviral treatment. The initial findings were replicated in four independent case-control sets (a total of 901 ACLFs and 1686 AsCs). The roles of risk variants on clinical traits of ACLF were also analysed. RESULTS Among 1300 ACLFs and 2087 AsCs, we identified rs3129859 at human leucocyte antigen (HLA) class II region (chromosome 6p21.32) associated with HBV-related ACLF (combined P dominant =2.64×10-20, OR=1.83). Analysis identified HLA-DRB1*12:02 as the top susceptible HLA allele associated with ACLF (p=3.94×10-6, OR=2.05). The association of rs3129859 was robust in ACLF subgroups (ACLFs with liver cirrhosis, p=1.36×10-16; ACLFs without liver cirrhosis, p=1.52×10-7), and patients at low-replicative phase (p=6.36×10-11, OR=2.29) or HBV e antigen-negative chronic hepatitis B phase (p=1.51×10-14, OR=1.86). Clinical traits analysis in patients with ACLF showed that the risky rs3129859*C allele was also associated with prolonged prothrombin time, faster progression to ascites development and higher 28-day mortality. CONCLUSIONS Our genome-wide association study identified HLA-DR as the major locus for susceptibility to HBV-related ACLF. Our findings highlight the importance of HLA class II restricted CD4+ T-cell pathway on the immunopathogenesis of HBV-related ACLF.

Ayurgenomics for stratified medicine: TRISUTRA consortium initiative across ethnically and geographically diverse Indian populations. JOURNAL OF ETHNOPHARMACOLOGY 2017; 197:274-293. [PMID: 27457695 DOI: 10.1016/j.jep.2016.07.063] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/18/2016] [Revised: 07/02/2016] [Accepted: 07/21/2016] [Indexed: 06/06/2023]
Abstract
BACKGROUND Genetic differences in the target proteins, metabolizing enzymes and transporters that contribute to inter-individual differences in drug response are not integrated in contemporary drug development programs. Ayurveda, that has propelled many drug discovery programs albeit for the search of new chemical entities incorporates inter-individual variability "Prakriti" in development and administration of drug in an individualized manner. Prakriti of an individual largely determines responsiveness to external environment including drugs as well as susceptibility to diseases. Prakriti has also been shown to have molecular and genomic correlates. We highlight how integration of Prakriti concepts can augment the efficiency of drug discovery and development programs through a unique initiative of Ayurgenomics TRISUTRA consortium. METHODS Five aspects that have been carried out are (1) analysis of variability in FDA approved pharmacogenomics genes/SNPs in exomes of 72 healthy individuals including predominant Prakriti types and matched controls from a North Indian Indo-European cohort (2) establishment of a consortium network and development of five genetically homogeneous cohorts from diverse ethnic and geo-climatic background (3) identification of parameters and development of uniform standard protocols for objective assessment of Prakriti types (4) development of protocols for Prakriti evaluation and its application in more than 7500 individuals in the five cohorts (5) Development of data and sample repository and integrative omics pipelines for identification of genomic correlates. RESULTS Highlight of the study are (1) Exome sequencing revealed significant differences between Prakriti types in 28 SNPs of 11 FDA approved genes of pharmacogenomics relevance viz. CYP2C19, CYP2B6, ESR1, F2, PGR, HLA-B, HLA-DQA1, HLA-DRB1, LDLR, CFTR, CPS1. These variations are polymorphic in diverse Indian and world populations included in 1000 genomes project. (2) Based on the phenotypic attributes of Prakriti we identified anthropometry for anatomical features, biophysical parameters for skin types, HRV for autonomic function tests, spirometry for vital capacity and gustometry for taste thresholds as objective parameters. (3) Comparison of Prakriti phenotypes across different ethnic, age and gender groups led to identification of invariant features as well as some that require weighted considerations across the cohorts. CONCLUSION Considering the molecular and genomics differences underlying Prakriti and relevance in disease pharmacogenomics studies, this novel integrative platform would help in identification of differently susceptible and drug responsive population. Additionally, integrated analysis of phenomic and genomic variations would not only allow identification of clinical and genomic markers of Prakriti for application in personalized medicine but also its integration in drug discovery and development programs.

Abstract
The aim of this study was to investigate possible involvement of estrogen receptor α (ESR1) in responding to pegylated interferon alpha-2a (PEG IFNα-2a) therapy in chronic hepatitis B (CHB) patients. A total of 106 HBeAg-positive patients and 52 healthy controls were enrolled into this study. ESR1 messenger RNA (mRNA) expression in peripheral blood mononuclear cells was quantified at the baseline, during treatment (weeks 4 and 12), and at the end of treatment (week 48) by real-time reverse transcriptase-polymerase chain reaction assay (RT-PCR). The sequence polymorphism of ESR1 (rs2077647, rs2234693, rs9340799, and rs9322354) was analyzed using the Sequenom MassARRAY Analyzer. Our results suggested that the most accurate prediction of nonresponder in female patients was the baseline alanine aminotransferase (ALT) in combination with ESR1 expression at week 4 of treatment (area under the receiver operating characteristic curve [AUC] = 0.908). Combining the baseline ALT with ESR1 mRNA expression at the end of treatment showed the best prediction of sustained virological response in male patients (AUC = 0.818). Internal validation was assessed by bootstrap cross-validation. These results may have clinical relevance and warrant future validation in studies with larger cohorts.

Abstract
Hepatitis B virus (HBV) is a common human pathogen transmitted worldwide, and its chronic infection is a well-known risk factor for hepatocellular carcinoma (HCC). The sex disparity of HBV-related liver diseases has been noticed for a long time, which could be attributed to sex hormone effects, other than gender behaviors or environmental impact. This difference is experimentally confirmed in HBV transgenic mice, as well as in immunocompetent mice receiving hydrodynamic delivery of HBV. Androgen and estrogen pathways were identified to play opposite regulations of HBV transcription by targeting viral enhancer I at molecular level. In addition to the direct effects on HBV life cycle, sex hormones may be also involved in the immune response to HBV infection and the progression of associated liver diseases, although the detailed mechanisms are still unclear. Besides, several unaddressed issues such as HBV entry, microRNA profiles, viral integration, and adaptability in which androgen and estrogen axes might be involved are warranted to be delineated. The comprehensive understanding of the sex disparity in HBV virology and pathogenesis will be helpful to provide newly biomarkers for clinical diagnosis and develop novel drugs to manage HBV-related HCC patients.

Abstract
Hepatitis E virus (HEV) infection causes high mortality in pregnant women. However, the pathogenic mechanisms of HEV infection in pregnant women remain unknown. In this study, the roles of pregnancy serum in HEV infection were investigated using an efficient cell culture system. HEV infection was exacerbated by supplementing with pregnancy serum, especially theat in third trimester of pregnancy. Oestrogen receptors (ER-α and ER-β) were activated in cells supplemented with pregnancy serum and were significantly inhibited during HEV infection. Type I IFN, especially IFN-β, showed delayed upregulation in HEV-infected cells supplemented with the serum in the third trimester of pregnancy, which indicated that delayed IFN-β expression may facilitate viral replication. Results suggested that pregnancy serum accelerated HEV replication by suppressing oestrogen receptors and type I IFN in the early stage of infection.

Yang D, Hanna DL, Usher J, LoCoco J, Chaudhari P, Lenz HJ, Setiawan VW, El-Khoueiry A. Impact of sex on the survival of patients with hepatocellular carcinoma: a Surveillance, Epidemiology, and End Results analysis. Cancer 2014; 120:3707-16. [PMID: 25081299 DOI: 10.1002/cncr.28912] [Citation(s) in RCA: 97] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2014] [Revised: 04/07/2014] [Accepted: 04/23/2014] [Indexed: 11/10/2022]
Abstract
BACKGROUND Men are 4 to 8 times more likely to develop hepatocellular carcinoma (HCC) than women. Preclinical models have suggested a role for sex hormones in the development of HCC. In the current study, the authors investigated the impact of age, sex, race, and ethnicity on the survival of patients with HCC using the Surveillance, Epidemiology, and End Results (SEER) database. METHODS Patients diagnosed with HCC from 1988 through 2010 were identified from the SEER registry. Hazard ratios (HR) for overall survival (OS) were derived using the Cox regression model adjusted for race, year of diagnosis, marital status, treatment, birthplace, tumor differentiation, and tumor size. RESULTS A total of 39,345 patients were identified; 76% were men and 34% were women (50% white, 12% African American, 21% Asian, 16% Hispanic, and 1% Native American). The median age at the time of diagnosis was 61 years for men and 67 years for women. Approximately 84% of patients had liver-limited disease and 16% had metastatic disease. Treatment information was available for patients diagnosed after 1998 (34,674 patients): 11% received liver-directed therapy, 11% underwent surgical resection, and 7% underwent liver transplantation. The HR for the OS of women versus men was 0.83 (95% confidence interval [95% CI], 0.77-0.88) for patients aged <55 years. The protective effect of sex on OS was found to be greatest in patients aged 18 to 44 years (HR, 0.75; 95% CI, 0.65-0.86 [P<.001]), especially those with surgically resected tumors (HR, 0.68; 95% CI, 0.54-0.86 [P = .001]) and those who were African American (HR, 0.85; 95% CI, 0.78-0.92 [P<.001]). There was no survival difference between sexes noted among Hispanics or patients aged >65 years. CONCLUSIONS Sex appears to be associated with survival in patients with HCC. The role of androgens and estrogens in the development and progression of HCC warrants further investigation.

[PMID: 25469118 PMCID: PMC4250527 DOI: 10.7555/jbr.28.20130162] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2013] [Revised: 11/28/2013] [Accepted: 04/07/2014] [Indexed: 01/04/2023] Open
Abstract
Several studies investigated associations of IFN-γ rs2430561 T/A, IL28B rs12979860 C/T and ERα rs2077647 T/C gene polymorphisms with outcomes of hepatitis B virus (HBV) infection, but the results were controversial. Therefore, we performed a meta-analysis of all published observational studies to address this inconsistency. Literature was searched in online database and a systematic review was conducted based on the search results. A total of 24 studies were included and dichotomous data were presented as odds ratio (OR) with a 95% confidence interval (CI). The rs2430561 T allele was associated with reduced persistent HBV infection risk (T vs. A: OR, 0.690; 95% CI, [0.490, 0.971]), while the rs2077647 T allele significantly increased the risk of persistent HBV infection (T vs. C: OR, 1.678; 95% CI, [1.212, 2.323]). Rs 2077647 CC might play a role in protecting individuals against HBV persistence (TT vs. CC: OR, 4.109; 95% CI, [2.609, 6.473]). Furthermore, carriers of the rs2430561 TT genotype were more likely to clear HBV spontaneously compared with those of the AA genotype (TT vs. AA: OR, 0.555; 95% CI, [0.359, 0.856]). For rs12979860 C/T polymorphism, no significant correlation with HBV infection outcomes was found. In subgroup analyses, the results were similar to those of overall analysis. However, for rs2077647 TT vs. TC+CC, significantly increased risks were observed in the Asian and hospital-based population, but not in the overall analysis. IFN-γ rs2430561 T/A and ERα rs2077647 T/C genetic polymorphisms were associated with outcomes of HBV infection, but no association was found between IL28B rs12979860 C/T and HBV infection.

Association of PvuII and XbaI polymorphisms in estrogen receptor alpha gene with the risk of hepatitis B virus infection in the Guangxi Zhuang population. INFECTION GENETICS AND EVOLUTION 2014; 27:69-76. [PMID: 25014269 DOI: 10.1016/j.meegid.2014.07.002] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/27/2014] [Revised: 06/30/2014] [Accepted: 07/03/2014] [Indexed: 12/14/2022]
Abstract
BACKGROUND AND OBJECTIVE Available evidence has suggested that estrogen receptor alpha (ESR1) is implicated in the pathogenic process of hepatitis B infection. Therefore, we evaluated the association of PvuII (rs2234693) and XbaI (rs9340799) in ESR1 and HBV infection in Guangxi Zhuang populations. METHODS A total of 389 subjects were divided into four groups: 112 patients with chronic hepatitis B (CHB), 65 patients with hepatitis B virus (HBV)-related liver cirrhosis (LC), 107 patients with HBV-related hepatocellular carcinoma (HCC), and 105 healthy controls. The polymerase chain reaction-restriction fragment length polymorphism strategy was used to detect ESR1 gene PvuII and XbaI polymorphisms. RESULTS Compared with healthy controls, binary logistic regression analyses show that the CC genotype of PvuII was associated with a significantly increased susceptibility to CHB compared with the TT genotype (OR=1.760, 95% CI 1.316-2.831; p=0.044). The PvuII CC genotype was also associated with significantly increased risk of HBV-related LC (OR=1.921, 95% CI 1.342-2.478; p=0.043). Similarly, the subjects bearing the homozygous CC genotype of PvuII polymorphism also had more than a 1.7-fold increased risk for development of HCC (OR=1.748, 95% CI 1.313-2.787; p=0.010) compared with those bearing the TT genotype. Furthermore, the AC haplotype was associated with a significantly increased risk of HCC with an OR of 1.456 (p=0.003). In contrast, there were no significant differences in the genotype and allele of XbaI polymorphisms in the ESR1 gene between the groups of patients and healthy controls. In addition, ESR1 polymorphisms were not significantly associated with susceptibility to HBV-related HCC when using CHB and LC patients as references. CONCLUSION We conclude that the CC genotype of PvuII in ESR1 is associated with an increased risk of CHB, HBV-related LC and HCC in Guangxi Zhuang populations.

Association of genetic variants in estrogen receptor α with HCV infection susceptibility and viral clearance in a high-risk Chinese population. Eur J Clin Microbiol Infect Dis 2014; 33:999-1010. [PMID: 24395301 DOI: 10.1007/s10096-013-2038-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2013] [Accepted: 12/15/2013] [Indexed: 12/15/2022]
Abstract
The purpose of this study was to test the hypothesis that genetic variants of estrogen receptor α (ERα) are associated with the outcomes of hepatitis C virus (HCV) infection. We genotyped the seven single nucleotide polymorphisms (SNPs) (rs2077647, rs9340799, rs2234693, rs1801132, rs9322354, rs2228480 and rs3798577) of ERα and conducted a case-control study in a high-risk Chinese population, including 429 HCV spontaneous clearance cases, 880 persistent infection cases and 1,174 uninfected controls. The C allele of rs2234693 was significantly associated with increased susceptibility to HCV infection [dominant model: adjusted odds ratio (OR) = 1.377, 95% confidence interval (CI) =1.126-1.778], and the risk effect remained significant among the younger (≤55 years) and hemodialysis subjects (all P < 0.007). The other three SNPs variant genotypes also showed significant correlation with elevated risk of HCV infection in different strata (rs2077647 in males; rs9340799 in blood donors; rs1801132 in younger subjects; all P < 0.007). It was also discovered that carriage of rs2228480 A allele was more prone to develop persistent HCV infection (dominant model: adjusted OR = 1.203, 95% CI = 1.154-1.552), and the risk effect was more evident in females and blood donors (all P < 0.007). Haplotype analyses (rs2077647, rs9340799 and rs2234693) showed that, compared with the most frequent haplotype TAT, CAC played a risk effect in subgroups of younger (P = 3.24 × 10(-3)) and male (P = 5.51 × 10(-4)), whereas CAT expressed a protective effect in females (P = 2.27 × 10(-4)) for HCV infection susceptibility. We first report that these SNPs (rs2077647, rs9340799, rs2234693, rs1801132 and rs2228480) in ERα can influence the outcomes of HCV infection in a high-risk Chinese population.

Abstract
AIM: To characterize high mobility group box chromosomal protein 1 (HMGB1) polymorphisms in patients infected with hepatitis B virus (HBV) and determine the different patterns in patient subgroups.
METHODS: A total of 1495 unrelated Han Chinese HBV carriers were recruited in this hospital-based case-control study. The HMGB1 1176 G/C polymorphism was genotyped by polymerase chain reaction-restriction fragment length polymorphism assay.
RESULTS: A significant association was observed between HMGB1 1176 G/C polymorphism and outcome of HBV infection. The subjects bearing 1176G/G genotype had an increased risk of susceptibility to chronic hepatitis B, liver cirrhosis and severe hepatitis B when compared with those bearing at least one 1176C allele.
CONCLUSION: Patients with 1176G/G genotype of HMGB1 gene are more likely to have a progressive status in HBV infection.

Polymorphism of estrogen receptor alpha (ESR1) is associated with virological response to entecavir (ETV) in nucleoside-naïve adult patients with chronic hepatitis B. Infection 2012; 41:371-8.

Abstract
INTRODUCTION Polymorphisms in estrogen receptor alpha (ESR1) are reported to be associated with the susceptibility to persistent HBV infection, HBV liver cirrhosis and HBV-related hepatocellular carcinoma (HCC). MATERIALS AND METHODS To test the hypothesis that polymorphisms in estrogen receptor alpha (ESR1) might influence the virological response to entecavir (ETV) therapy, we examined two polymorphisms (PvuII and XbaI) in 76 nucleoside-naïve chronic hepatitis B (CHB) patients. All of the patients (52 HBeAg-positive and 24 HBeAg-negative) were treated with ETV 0.5 mg daily and followed up for a median time of 96 weeks (range 48-96). Polymorphisms were determined using the polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) method. RESULTS Under an additive model, the univariate analysis showed that patients carrying the PvuII T/C genotype might have higher virological responders than those carrying the T/T and C/C genotypes at week 48 (87.7 vs. 57.1 vs. 58.3 %; P = 0.012) and week 96 (96.7 vs. 64.3 vs. 24 87.5 %; P = 0.018), although this difference disappeared with the multiple analysis at week 48 [95 % confidence interval (CI) 0.687-3.841; P = 0.269] and week 96 (95 % CI 0.861-18.016; P = 0.077). Conversely, the univariate analysis suggests statistical significance between the recessive model of PvuII (TT vs. TC/CC) and virological response at week 48 (57.1 vs. 81.1 %; P = 0.033) and week 96 (64.3 vs. 94.7 %; P = 0.017). Multiple regression analysis affirmed the significant and independent association between the recessive model of PvuII and virological response. In other words, patients carrying at least one PvuII C allele (TC/CC) had a better likelihood of achieving virological response compared with those carrying the T/T genotype at week 48 (95 % CI 1.026-14.785, P = 0.046) and week 96 (95 % CI 1.456-57.509; P = 0.018). XbaI polymorphisms were not significantly associated with virological response. CONCLUSION Our results suggest that the PvuII polymorphism may play an important role in determining ETV efficacy after 48 and 96 weeks of treatment, at least in this study population.

Abstract
BACKGROUND The sexual dimorphism of hepatitis B virus (HBV) -related liver diseases is related with estrogen and its receptors. Recent reports indicate that abnormal expression of estrogen receptor alpha (ESR1) may be a hallmark for the progression of liver disease and HBV carriers presenting variant ESR1 have an extremely aggressive clinical course. Here we examine whether the ESR1 polymorphisms or its haplotypes are related to HBV-related acute liver failure (ALF) risk among chronic HBV carriers in a Chinese population. METHODS A total of 1216 unrelated Han Chinese HBV carriers were recruited in this hospital-based case-control study, including 359 HBV surface antigen (HBsAg) carriers affected with ALF and 857 asymptomatic HBsAg carriers. Two ESR1 haplotype tagging polymorphisms, c.30 T > C (rs2077647) and c.453-397 T > C (rs2234693), were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. RESULTS We observed a significantly increased susceptibility to HBV-ALF associated with the c.30 C allele (P = 8.65 × 10-4), c.453-397 C allele (5.37 × 10-4) and [c.30 C; c.453-397 C] haplotype (Dominant model, P =0.0004, odds ratio = 1.53, 95% CI 1.23 ~ 1.96) compared with the T alleles and [c.30 T; c.453-397 T] haplotype of c.30 T > C and c.453-397 T > C polymorphisms, respectively. CONCLUSIONS Our study suggests that [c.30 C; c.453-397 C] haplotype may be a risk factor for genetic susceptibility to HBV-related ALF in the Chinese population. It also emphasizes the importance of ESR1 in the pathophysiology of HBV-related ALF on the population level.

Limited effects of bile acids and small heterodimer partner on hepatitis B virus biosynthesis in vivo. J Virol 2011; 86:2760-8.

Abstract
Multiple nuclear receptors, including hepatocyte nuclear factor 4α (HNF4α), retinoid X receptor α (RXRα) plus peroxisome proliferator-activated receptor α (PPARα), RXRα plus farnesoid X receptor α (FXRα), liver receptor homolog 1 (LRH1), and estrogen-related receptors (ERRs), have been shown to support efficient viral biosynthesis in nonhepatoma cells in the absence of additional liver-enriched transcription factors. Although HNF4α has been shown to be critical for the developmental expression of hepatitis B virus (HBV) biosynthesis in the liver, the relative importance of the various nuclear receptors capable of supporting viral transcription and replication in the adult in vivo has not been clearly established. To investigate the role of the nuclear receptor FXR and the corepressor small heterodimer partner (SHP) in viral biosynthesis in vivo, SHP-expressing and SHP-null HBV transgenic mice were fed a bile acid-supplemented diet. The increased FXR activity and SHP expression levels resulting from bile acid treatment did not greatly modulate HBV RNA and DNA synthesis. Therefore, FXR and SHP appear to play a limited role in modulating HBV biosynthesis, suggesting that alternative nuclear receptors are more critical determinants of viral transcription in the HBV transgenic mouse model of chronic viral infection. These observations suggest that hepatic bile acid levels or therapeutic agents targeting FXR may not greatly modulate viremia during natural infection.
