Functional long non-coding RNAs in hepatocellular carcinoma.

Area of Science:

• Molecular Biology
• Oncology
• Genetics

Background:

• Hepatocellular carcinoma (HCC) is a major global cancer with poorly understood molecular drivers.
• Long non-coding RNAs (lncRNAs) have emerged as critical regulators in hepatocarcinogenesis.
• Dysregulated lncRNAs are linked to HCC-associated liver diseases like viral hepatitis and cirrhosis.

Purpose of the Study:

• To review the biogenesis and function of lncRNAs in HCC.
• To summarize lncRNA roles in key HCC malignant hallmarks.
• To discuss lncRNA involvement in pre-cancerous liver conditions and their potential clinical applications.

Main Methods:

• Literature review of studies on lncRNAs in HCC.
• Analysis of lncRNA regulatory mechanisms in cancer development.
• Synthesis of current knowledge on lncRNA functions in liver disease and HCC.

Main Results:

• lncRNAs modulate critical HCC phenotypes including proliferation, apoptosis resistance, metabolism, immune evasion, angiogenesis, and metastasis.
• lncRNA dysregulation is implicated in the progression of liver diseases that predispose to HCC.
• lncRNAs represent promising targets for early HCC diagnosis and therapy.

Conclusions:

• lncRNAs play multifaceted roles in HCC development and progression.
• Targeting lncRNAs could offer novel avenues for HCC treatment and prevention.
• Further research into lncRNA regulatory networks is crucial for advancing HCC management.
