Phosphorylation of Phylogenetically Conserved Amino Acid Residues Confines HBx within Different Cell Compartments of Human Hepatocarcinoma Cells

Molecules, 2021
Hepatitis B virus (HBV) is a circular, and partially double-stranded DNA virus. Upon infection, the viral genome is translocated into the cell nucleus, generating the covalently closed circular DNA (cccDNA) intermediate, and forming a mini chromosome ...

Silicon Nanowire Field-Effect Transistor as Label-Free Detection of Hepatitis B Virus Proteins with Opposite Net Charges

Biosensors, 2021
The prevalence of hepatitis B virus (HBV) is a global healthcare threat, particularly chronic hepatitis B (CHB) that might lead to hepatocellular carcinoma (HCC) should not be neglected.

Codelivery of HBx-siRNA and Plasmid Encoding IL-12 for Inhibition of Hepatitis B Virus and Reactivation of Antiviral Immunity

Pharmaceutics, 2022
Chronic hepatitis B is a critical cause of many serious liver diseases such as hepatocellular carcinoma (HCC). The main challenges in hepatitis B treatment include the rebound of hepatitis B virus (HBV)-related antigen levels after drug withdrawal and ...

The hepatitis B virus X protein activates nuclear factor of activated T cells (NF-AT) by a cyclosporin A-sensitive pathway. [PDF]

, 1998
The X gene product of the human hepatitis B virus (HBx) is a transcriptional activator of various viral and cellular genes. We recently have determined that the production of tumor necrosis factor-alpha (TNF-alpha) by HBV-infected hepatocytes is ...

Expression of X protein and hepatitis B virus replication in chronic hepatitis

Hepatology, 1991
The X protein can act on the enhancer of hepatitis B virus in an in vitro system and elevate the transcriptional level of hepatitis B virus. However, because no relationship had been reported between X protein expression and hepatitis B virus replication in patients with chronic hepatitis B, we focused on its expression in the

Hepatitis B Virus X Protein: The X Factor in Chronic Hepatitis B Virus Disease Progression

Indian Journal of Medical Microbiology, 2019
Hepatitis B virus (HBV) is the most common aetiological factor causing hepatocellular carcinoma (HCC). HBx gene plays an enigmatic role in HBV-related HCC. In this study we have analysed amino acid substitutions in HBx from HBV-infected individuals of different clinical stages.HBV-infected individuals (n = 93) were recruited in the study.

Re-evaluation of the carcinogenic significance of hepatitis B virus integration in hepatocarcinogenesis [PDF]

, 2012
To examine the role of hepatitis B virus (HBV) integration in hepatocarcinogenesis, a systematic comparative study of both tumor and their corresponding non-tumor derived tissue has been conducted in a cohort of 60 HBV associated hepatocellular carcinoma

Hepatitis B virus X protein in liver tumor microenvironment [PDF]

Tumor Biology, 2016
Encoded by the hepatitis B virus, hepatitis B virus X protein (HBx) is a multifunctional, potentially oncogenic protein that acts primarily during the progression from chronic hepatitis B to cirrhosis and hepatocellular carcinoma (HCC). In recent decades, it has been established that chronic inflammation generates a tumor-supporting microenvironment ...

Hepatitis C virus p7 protein is crucial for assembly and release of infectious virions [PDF]

, 2007
Hepatitis C virus (HCV) infection is associated with chronic liver disease and currently affects about 3% of the world population. Although much has been learned about the function of individual viral proteins, the role of the HCV p7 protein in virus ...

Biochemistry and Functions of Hepatitis B Virus X Protein

Intervirology, 1995
Hepatitis B virus X gene codes for a small basic cytoplasmic protein and is able to transactivate viral and cellular genes, although X protein exhibits no DNA-binding activity. The mechanism of transactivation by X protein has been suggested to be via protein-protein interaction(s).
