Non-coding RNA and Atherosclerosis

The overwhelming majority of genes in the human genome encode RNA molecules that are not translated into proteins. These RNA molecules are named non-coding RNAs (ncRNAs). ncRNAs play a crucial role in the regulation of gene expression and abnormalities in ncRNAs can cause disease progression, including atherosclerosis. ncRNAs regulate different stages of atherosclerosis progression, such as foam cell formation and lipid metabolism. Diverse types of ncRNAs have been studied, but the best known and widely used are small non-coding (sncRNAs), specifically microRNAs and small interfering RNAs, which are ∼22 nucleotides long. The majority of drugs based on ncRNAs are composed of sncRNAs. There is strong evidence that besides sncRNAs, other types of ncRNAs, such as long ncRNAs and circular RNAs, take part in the regulation of gene expression. This review summarized recent advances in ncRNAs and atherosclerosis.
