Chronic HBV infection, stemness pathways, and compromised immune surveillance in HCC development

Area of Science:

• Hepatology
• Molecular Oncology
• Virology

Background:

• Chronic hepatitis B virus (HBV) infection is a primary cause of hepatocellular carcinoma (HCC).
• Stemness transcription factors OCT4, Sox2, and NANOG play critical roles in cancer development.
• Understanding the link between HBV and these factors is crucial for HCC management.

Purpose of the Study:

• To elucidate the molecular mechanisms by which HBV infection upregulates OCT4, Sox2, and NANOG expression.
• To explore the role of these transcription factors in HBV-associated HCC pathogenesis.
• To identify potential biomarkers and therapeutic targets for HCC.

Main Methods:

• Comprehensive literature review of studies investigating HBV, stemness factors, and HCC.
• Analysis of molecular pathways including HBxAg effects, KDM5B activation, and viral integration.
• Examination of the association between factor dysregulation and clinical outcomes.

Main Results:

• HBV enhances OCT4, Sox2, and NANOG expression through mechanisms like HBxAg-induced chromatin remodeling, KDM5B activation, and HBx-ΔC integration.
• Chronic inflammation from HBV infection contributes to the overexpression of these factors.
• Dysregulated OCT4, Sox2, and NANOG correlate with increased tumor proliferation, metastasis, and poor prognosis in HCC patients.

Conclusions:

• HBV-induced alterations in OCT4, Sox2, and NANOG are critical oncogenic drivers in HCC.
• These transcription factors represent promising biomarkers for early HCC detection and prognosis.
• Targeting OCT4, Sox2, and NANOG offers potential therapeutic strategies for HBV-related HCC.
