Summary
Hepatocellular carcinoma (HCC) is linked to Hepatitis B virus (HBV) infection. Occult HBV infection, even without surface antigen, poses a significant risk for HCC development through similar mechanisms as overt HBV.
Area of Science:
- Hepatology
- Virology
- Oncology
Background:
- Hepatocellular carcinoma (HCC) development is multifactorial, with Hepatitis B virus (HBV) infection being a primary risk factor.
- Chronic inflammation and cytokine activity are critical in liver fibrosis and cell proliferation, contributing to hepatocarcinogenesis.
- Direct cellular effects from HBV DNA integration or protein expression can influence liver cell function.
Purpose of the Study:
- To elucidate the role of occult Hepatitis B virus (HBV) infection in Hepatocellular carcinoma (HCC) development.
- To explore the mechanisms by which occult HBV infection contributes to liver cancer.
- To compare the oncogenic potential of occult HBV with overt HBV infection.
Main Methods:
- Review of existing evidence on HBV infection and HCC.
- Analysis of studies investigating occult HBV infection.
- Examination of molecular mechanisms linking HBV to liver cell proliferation and fibrosis.
Main Results:
- Occult HBV infection, defined by the presence of HBV DNA in HBsAg-negative individuals, is identified as a risk factor for HCC.
- The mechanisms driving tumorigenesis in occult HBV infection appear to mirror those of overt HBV infection.
- HBV DNA integration and protein expression are implicated in altering cellular functions relevant to cancer development.
Conclusions:
- Occult Hepatitis B virus infection represents a significant, yet often undetected, risk factor for Hepatocellular carcinoma.
- The pathogenic pathways involved in occult HBV-induced HCC are largely consistent with those of overt HBV infection.
- Further research into occult HBV is crucial for comprehensive HCC prevention and management strategies.

01:25Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
01:28Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
01:51Mechanisms of Retrovirus-induced Cancers
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

01:23Cirrhosis I: Introduction
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
