Abstract
The field of ribonucleic acid (RNA) biology has revealed an array of noncoding RNA
species, particularly long noncoding RNAs (lncRNAs), which play crucial roles in liver
disease pathogenesis. This review explores the diverse functions of lncRNAs in liver
pathology, including metabolic-associated steatotic liver disease, hepatocellular
carcinoma, alcohol-related liver disease, and cholangiopathies such as primary sclerosing
cholangitis and cholangiocarcinoma. We highlight key lncRNAs that regulate lipid metabolism,
inflammation, fibrosis, and oncogenesis in the liver, demonstrating their diagnostic
and therapeutic potential. Emerging RNA-based therapies, such as mRNA therapy, RNA
interference, and antisense oligonucleotides, offer approaches to modulate lncRNA
activity and address liver disease at a molecular level. Advances in sequencing technologies
and bioinformatics pipelines are simultaneously enabling the identification and functional
characterization of novel lncRNAs, driving innovation in personalized medicine. In
conclusion, this review highlights the potential of lncRNAs as biomarkers and therapeutic
targets in liver disease and emphasizes the need for further research into their regulatory
mechanisms and clinical applications.
