Non-coding RNAs in alcohol-associated liver disease.

Area of Science:

• Molecular Biology
• Hepatology
• Genetics

Background:

• Non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), regulate gene expression.
• Chronic alcohol consumption significantly impacts ncRNA expression and function in the liver and circulation.
• Dysregulated ncRNAs are implicated in the pathogenesis of alcohol-associated liver disease (ALD).

Purpose of the Study:

• To provide a comprehensive overview of the roles of ncRNAs in ALD.
• To elucidate the mechanistic contributions of ncRNAs to ALD development and progression.
• To discuss the potential of ncRNAs as diagnostic biomarkers and therapeutic targets for ALD.

Main Methods:

• Literature review of studies investigating ncRNAs in alcohol-associated liver disease.
• Analysis of ncRNA involvement in key pathways such as hepatocyte injury, lipid metabolism, inflammation, and hepatic stellate cell activation.
• Examination of the role of extracellular vesicles in ncRNA-mediated intercellular communication in ALD.

Main Results:

• ncRNAs critically regulate gene expression and cellular functions relevant to liver health.
• Disrupted ncRNA expression in ALD exacerbates steatosis, inflammation, and fibrosis.
• Extracellular vesicles mediate ncRNA communication, amplifying liver damage and fibrosis in ALD.

Conclusions:

• ncRNAs play multifaceted roles in the pathogenesis and progression of ALD.
• ncRNAs represent promising diagnostic biomarkers for ALD.
• ncRNAs hold significant translational potential as therapeutic targets for ALD.
