LncRNAs Ride the Storm of Epigenetic Marks

Advancements in genome sequencing technologies have uncovered the multifaceted roles of long non-coding RNAs (lncRNAs) in human cells. Recent discoveries have identified lncRNAs as major players in gene regulatory pathways, highlighting their pivotal role in human cell growth and development. Their dysregulation is implicated in the onset of genetic disorders and age-related diseases, including cancer. Specifically, they have been found to orchestrate molecular mechanisms impacting epigenetics, including DNA methylation and hydroxymethylation, histone modifications, and chromatin remodeling, thereby significantly influencing gene expression. This review provides an overview of the current knowledge on lncRNA-mediated epigenetic regulation of gene expression, emphasizing the biomedical implications of lncRNAs in the development of different types of cancers and genetic diseases.
