Differential methylation patterns in paternally imprinted gene promoter regions in sperm from hepatitis B virus infected individuals. BMC Mol Cell Biol 2024; 25:19. [PMID: 39090552 PMCID: PMC11295637 DOI: 10.1186/s12860-024-00515-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 07/24/2024] [Indexed: 08/04/2024] Open
Abstract
BACKGROUND Hepatitis B virus (HBV) infection poses a substantial threat to human health, impacting not only infected individuals but also potentially exerting adverse effects on the health of their offspring. The underlying mechanisms driving this phenomenon remain elusive. This study aims to shed light on this issue by examining alterations in paternally imprinted genes within sperm. METHODS A cohort of 35 individuals with normal semen analysis, comprising 17 hepatitis B surface antigen (HBsAg)-positive and 18 negative individuals, was recruited. Based on the previous research and the Online Mendelian Inheritance in Man database (OMIM, https://www.omim.org/ ), targeted promoter methylation sequencing was employed to investigate 28 paternally imprinted genes associated with various diseases. RESULTS Bioinformatic analyses revealed 42 differentially methylated sites across 29 CpG islands within 19 genes and four differentially methylated CpG islands within four genes. At the gene level, an increase in methylation of DNMT1 and a decrease in methylation of CUL7, PRKAG2, and TP53 were observed. DNA methylation haplotype analysis identified 51 differentially methylated haplotypes within 36 CpG islands across 22 genes. CONCLUSIONS This is the first study to explore the effects of HBV infection on sperm DNA methylation and the potential underlying mechanisms of intergenerational influence of paternal HBV infection.

Int J Epidemiol 2021; 51:448-457. [PMID: 34966942 PMCID: PMC9308392 DOI: 10.1093/ije/dyab262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Accepted: 12/07/2021] [Indexed: 02/03/2023] Open
Abstract
BACKGROUND Although viral hepatitis causes paediatric hepatocellular carcinoma and hepatic and extrahepatic cancers in adults, there are few epidemiologic studies on paediatric-cancer risks from parental viral hepatitis. In a nationwide study in a viral hepatitis endemic region and with confirmation in another population-based sample, we examined associations between parental hepatitis B (HBV) and C (HCV) infections and risks of cancers in offspring. METHODS We included all children born in Taiwan in 2004-2014 (N = 2 079 037) with 2160 cancer cases ascertained from the Cancer Registry. We estimated risks for paediatric cancers using Cox proportional-hazard regressions. We checked these associations in a nationwide case-control study in Denmark (6422 cases, 160 522 controls). RESULTS In Taiwan, paternal HBV was related to child's hepatoblastoma [hazard ratio (HR) = 1.77, 95% confidence interval (CI) = 1.05, 2.97] when identified at any time in the medical record, and when analyses were limited to hepatitis diagnoses occurring before the child's birth, risks increased (HR = 2.08, 95% CI = 1.13-3.80). Paternal HCV was related to child's non-Hodgkin lymphoma (HR = 2.06, 95% CI = 1.13-3.74). Maternal HCV was weakly related to increased risks of all childhood cancers [all types combined; HR = 1.45, 95% CI = 0.95-2.22]. The population-attributable fraction of hepatoblastoma for maternal, paternal and child HBV was 2.6%, 6.8% and 2.8%, respectively. CONCLUSIONS Parental HBV and HCV may be risk factors for hepatic and non-hepatic cancers in children. If associations are causal, then parental screening and treatment with antivirals may prevent some paediatric cancers.

Abstract
Interferon (IFN) α is used for the treatment of chronic hepatitis B virus (HBV) infection, but the molecular mechanisms underlying its antiviral effect have not been fully elucidated. Epigenetic modifications regulate the transcriptional activity of covalently closed circular DNA (cccDNA) in cells with chronic HBV infection. IFN‑α has been shown to modify cccDNA‑bound histones, but it is not known whether the anti‑HBV effect of IFN‑α involves methylation of cccDNA. The present study aimed to determine whether IFN‑α induced methylation of HBV cccDNA in a cell‑based model in which HepG2 cells were directly infected with wild‑type HBV virions. Methylation status of HBV cccDNA was assessed using global DNA methylation ELISA assay, methylation‑specific PCR and bisulfite sequencing. IFN‑α suppressed HBV DNA and RNA transcripts, but methylation profiles were similar between the control and IFN‑α treated groups. Chromatin immunoprecipitation results revealed binding of DNA methyltransferases (DNMT) 3A and DNMT3B to HBV cccDNA and treatment with IFN‑α suppressed the recruitment of DNMT3B to cccDNA. Taken together, these results suggest that IFN‑α does not induce methylation of HBV cccDNA. Therefore, it was concluded that methylation is unlikely to contribute to the anti‑HBV effect of IFN‑α in HepG2 cells, and that alternative mechanisms need to be sought to enhance cccDNA methylation as a novel therapy against HBV.

Abstract
Human sperm nucleus contains diverse RNA populations. This study aimed to screen and identify host microRNAs (miRs) that regulate gene expression of hepatitis B virus (HBV) during transmission from patients' sperm to sperm-derived embryos. Using microarrays, 336 miRs were found to be differentially expressed. After validation using real-time quantitative RT-PCR (RT-qPCR), four miRs were selected as targets. Using RT-qPCR and enzyme-linked immunosorbent assays, when patients' sperm were treated with mimics (or inhibitors) specific for hsa-miR-19a-3p and hsa-miR-29c-3p, the S gene transcription in sperm and translation in sperm-derived embryos was downregulated (or upregulated). There were significant differences in transcriptional and translational levels of the S gene between the test and control groups. These findings suggest that hsa-miR-19a-3p and hsa-miR-29c-3p significantly suppressed expression of the S gene, offering potential therapeutic targets for treating patients with HBV infection, and further reducing the negative impact of HBV infection on sperm fertilizing capacity.

Abstract
Hepatitis B virus (HBV) infection may affect sperm motility in patients with HBV. HBV surface protein (HBs) decreases mitochondrial membrane potential, impairs motility and induces apoptotic-like changes in human spermatozoa. However, little is known about how human spermatozoa respond to reactive oxygen species (ROS; mainly peroxides) induced by HBs. In this study, HBs induced supraphysiological ROS levels in human spermatozoa and reduced the formation of 2-cell embryos (obtained from hamster oocytes and human spermatozoa). HBs induced a pre-apoptotic status in human spermatozoa, as well as antioxidant defences by increasing glutathione peroxidase 4 (GPX4) and peroxiredoxin 5 (PRDX5) levels. These results highlight the molecular mechanism responsible for the oxidative stress in human spermatozoa exposed to HBV and the antioxidant defence response involving GPX4 and PRDX5.

Abstract
Hepatitis B virus (HBV) has infected one-third of world population, and 240 million people are chronic carriers, to whom a curative therapy is still not available. Similar to other viruses, persistent HBV infection relies on the virus to exploit host cell functions to support its replication and efficiently evade host innate and adaptive antiviral immunity. Understanding HBV replication and concomitant host cell interactions is thus instrumental for development of therapeutics to disrupt the virus-host interactions critical for its persistence and cure chronic hepatitis B. Although the currently available cell culture systems of HBV infection are refractory to genome-wide high throughput screening of key host cellular factors essential for and/or regulating HBV replication, classic one-gene (or pathway)-at-a-time studies in the last several decades have already revealed many aspects of HBV-host interactions. An overview of the landscape of HBV-hepatocyte interaction indicates that, in addition to more tightly suppressing viral replication by directly targeting viral proteins, disruption of key viral-host cell interactions to eliminate or inactivate the covalently closed circular (ccc) DNA, the most stable HBV replication intermediate that exists as an episomal minichromosome in the nucleus of infected hepatocyte, is essential to achieve a functional cure of chronic hepatitis B. Moreover, therapeutic targeting of integrated HBV DNA and their transcripts may also be required to induce hepatitis B virus surface antigen (HBsAg) seroclearance and prevent liver carcinogenesis.

Abstract
The stimulator of interferon genes (STING) plays a crucial role in the recognition of a viral infection and subsequent stimulation of an immune response. However, it is unclear whether methylation of the STING promoter affects STING transcription and response to antiviral therapy. The present study determined the methylation status of the STING promoter in patients with chronic hepatitis B (CHB).This study included 198 participants, of which 159 participants had CHB and 39 were healthy controls (HCs). Methylation-specific polymerase chain reaction was performed to detect the methylation status of the STING promoter. Reverse transcription-quantitative polymerase chain reaction was performed to determine STING mRNA level in peripheral blood mononuclear cells.The methylation frequency of the STING promoter was significantly higher and STING mRNA level was lower in the patients with CHB than in the HCs. Presence of hepatitis B virus (HBV) DNA was independently correlated with an increased risk of STING promoter methylation. Virological response frequency was higher in the patients with CHB receiving entecavir (ETV) than in those receiving adefovir (ADV). In the ETV group, the virological response frequency was evidently lower in the patients with CHB having methylated STING promoters than in those having unmethylated STING promoters. However, there was no significant difference in the virological response frequency between ADV-treated patients having methylated and unmethylated STING promoters.These results indicate that the hypermethylation of the STING promoter and thus the transcriptional repression of STING weaken the effect of STING in inhibiting HBV replication and decreases the effectiveness of antiviral therapy.

Abstract
PURPOSE This study aimed to determine the effect of paternal hepatitis B virus (HBV) infection on reproductive outcomes of couples undergoing frozen-thawed embryo transfer (FET). METHODS This retrospective cohort study included FET cycles performed between January 2014 and March 2017 in couples with a hepatitis B surface antigen (HBsAg)-positive male partner and an HBsAg-negative female partner, which was categorized as HBsAg group. The FET cycles underwent by couples with both HBsAg-negative partners were randomly selected as controls. The primary outcome was clinical pregnancy. RESULTS A total of 117 FET cycles, comprising 39 in the HBsAg group and 78 in the control group, were included. Couples with HBsAg-positive male partners had significantly lower clinical pregnancy rate (17.9 vs 41.0%, P = 0.013), lower implantation rate (11.1 vs 24.5%, P = 0.014), and lower live birth rate (12.8 vs 30.8%, P = 0.034) compared with the control group. Moreover, the multivariate logistic regression analysis showed that paternal HBV infection was negatively associated with clinical pregnancy (odds ratio = 0.297, 95% confidence interval 0.108-0.817, P = 0.019). The miscarriage rate was not significantly different between the two groups (28.6 vs 25.0%, P = 1.000). CONCLUSIONS Paternal HBV infection resulted in a lower frequency of clinical pregnancy after FET, a difference that was probably attributed to a detrimental effect of HBV on the ability of embryos to survive freezing and thawing.

Abstract
Hepatitis B virus (HBV) can invade the male germline, and sperm-introduced HBV genes could be transcribed in embryo. This study was to explore whether viral gene transcription is regulated by host genes. Embryos were produced by in vitro fertilization of hamster oocytes with human sperm containing the HBV genome. Total RNA extracted from test and control embryos were subjected to SMART-PCR, SSH, microarray hybridization, sequencing and BLAST analysis. Twenty-nine sequences showing significant identity to five human gene families were identified, with CSH2, EIF4G2, PCBD2, PSG4 and TTN selected to represent target genes. Using qRT-PCR, when CSH2 and PCBD2 (or EIF4G2, PSG4 and TTN) were silenced by RNAi, transcriptional levels of HBV s and x genes decreased (or increased). This is the first report that host genes participate in regulation of sperm-introduced HBV gene transcription in embryo, which is critical to prevent negative impact of HBV infection on early embryonic development.
