AI Article Synopsis

  • Recent studies show that methylation in the hepatitis B virus (HBV) genome could play a role in controlling how the virus replicates and is transcribed.
  • The connection between this methylation and occult hepatitis is still uncertain.
  • Research found specific CpG sites in the HBV genome that are often hypermethylated in liver cancer patients, but not in those with chronic hepatitis.

Article Abstract

Recent studies have identified the presence of methylation in the hepatitis B virus (HBV) genome and have suggested that it may be an important mechanism regulating transcription and replication of the HBV virus. However, it remains unclear whether this phenomenon is associated with occult hepatitis. Here, we performed a detailed analysis of DNA methylation in the HBV genome in liver samples of patients at different stages of hepatocarcinoma development and in in vitro infected hepatocytes and found discrete CpG sites in the HBV genome that are recurrently hypermethylated in cancer but not in chronic hepatitis tissue.

Hepatitis B virus (HBV) DNA integration into the host cell genome is reportedly a major cause of liver cancer, and a source of hepatitis B surface antigen (HBsAg). High HBsAg levels can alter immune responses which therefore contributes to the progression of HBV-related disease. However, to what extent integration leads to the persistent circulating HBsAg is unclear.

Background: In regions with a high prevalence of chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, coinfected patients face a heightened risk of developing hepatocellular carcinoma (HCC), termed HBV/HCV-related HCC (HBCV-HCC). We aimed to investigate the contribution of preexisting chronic hepatitis B (CHB) and subsequent chronic hepatitis C (CHC) to the development of HBCV-HCC.

Methods: We examined HBV's involvement in 93 HBCV-HCC cases by analyzing HBV DNA integration as an indicator of HCC originating from HBV-infected hepatocytes, compared with 164 HBV-HCCs and 56 HCV-HCCs as controls.

Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) are known as the most common blood-borne viral infections worldwide. Individuals referring to drop-in centers (DICs) are considered high-risk people exposed to infection with blood-borne viruses. The purpose of this study was to investigate the prevalence of HIV, HBV, and HCV infections among women referred to DICs in Lorestan Province, western Iran.

Immune checkpoint inhibitor (ICI) therapy is the new standard treatment for advanced or metastatic hepatocellular carcinoma (HCC); however, many patients still fail to respond. This study explored the expression and prognosis of programmed death ligand 1 (PD-L1), cluster of differentiation 24 (CD24), and cluster of differentiation 47 (CD47) in patients with hepatitis B virus-associated HCC (HBV-associated HCC). We analyzed sequencing data from the Cancer Genome Atlas (TCGA) and investigated the expression of PD-L1, CD24, and CD47 in HBV-associated HCC patients by immunohistochemistry and their relationship with prognosis and clinicopathological factors.

Hepatitis B is a viral infection of the liver caused by the hepatitis B virus (HBV). Entecavir (ETV) is considered the primary therapeutic option for HBV treatment, primarily functioning by inhibiting HBV replication. Ubiquitin-specific peptidase 7 (USP7), a deubiquitinating enzyme, plays a crucial role in regulating DNA repair mechanisms.
