Mutations at Nucleotide 1762, 1764 and 1766 of Hepatitis B Virus X Gene in Patients with Chronic Hepatitis B and Hepatitis B-Related Cirrhosis
Abstract Background and objective: Hepatitis B virus (HBV) is a DNA virus with high tendency toward hepatic tissue. There are currently about 3 million HBV-infected people and 350 to 400 million chronic carriers of this virus in the world. X protein plays a role in the over-expression of oncogenes, carcinogenicity of liver cells and overlaps with the basal co...
متن کاملIn Silico Prediction and Docking of Tertiary Structure of Multifunctional Protein X of Hepatitis B Virus
Hepatitis B virus (HBV) infection is a universal health problem and may result into acute, fulminant, chronic hepatitis liver cirrhosis, or hepatocellular carcinoma. Sequence for protein X of HBV was retrieved from Uniprot database. ProtParam from ExPAsy server was used to investigate the physicochemical properties of the protein. Homology modeling was carried out using Phyre2 server, and refin...
متن کاملHepatitis B Virus X Protein and Hepatocarcinogenesis
Chronic hepatitis B virus (HBV) infection is one of the most associated factors in hepatocarcinogenesis. HBV is able to integrate into the host genome and encode the multi-functional hepatitis B virus x protein (HBx). Although the mechanism between HBx and carcinogenesis is still elusive, recent studies have shown that HBx was able to influence various signaling pathways, as well as epigenetic ...
متن کاملThe hepatitis B virus X protein transactivates viral core gene expression in vivo.
The function of the X protein in the life cycle of mammalian hepadnaviruses is unclear. Based on tissue culture experiments it has been suggested that this protein represents a transcriptional transactivator which might be essential for the expression of the viral core gene. Here we have examined whether the activity of the human hepatitis B virus (HBV) core gene in vivo depends on X coexpressi...
متن کاملHepatitis B virus X protein enhances androgen receptor-responsive gene expression depending on androgen level.
Persistent hepatitis B virus (HBV) infection is a major risk of hepatocellular carcinoma (HCC). One intriguing feature of HBV-related HCC is the male predominance, with a male to female ratio of 5-7:1. This dominance has been attributed to the elevated androgen level and the enhanced androgen receptor (AR)-mediated activity in the host. How HBV infection and AR signaling modulate HCC is unknown...
