Mechanisms of Action and Biomarker Potential of ncRNAs in Hepatocellular Carcinoma and Liver Fibrosis: A Review.

Liver diseases constitute a major global health burden, contributing substantially to morbidity and mortality worldwide. Although effective therapeutic strategies have been developed for key risk factors, such as hepatitis C infection, therapeutic options for most other liver diseases remain limited. Noncoding RNAs (ncRNAs), which regulate diverse cellular and molecular processes, have emerged as promising therapeutic targets and biomarkers in liver diseases. In this study, we summarize the mechanisms of action and functional roles of ncRNAs, such as long ncRNAs (lncRNAs), circular RNAs (circRNAs), and PIWI-interacting RNAs (piRNAs), to improve therapeutic strategies and diagnostic precision in liver diseases, such as liver fibrosis and hepatocellular carcinoma (HCC).
