The Emerging Role of MicroRNA-155 in Cardiovascular Diseases

Abstract EN

MicroRNAs have been demonstrated to be involved in human diseases, including cardiovascular diseases.

Growing evidences suggest that microRNA-155, a typical multifunctional microRNA, plays a crucial role in hematopoietic lineage differentiation, immunity, inflammation, viral infections, and vascular remodeling, which is linked to cardiovascular diseases such as coronary artery disease, abdominal aortic aneurysm, heart failure, and diabetic heart disease.

The effects of microRNA-155 in different cell types through different target genes result in different mechanisms in diseases.

MicroRNA-155 has been intensively studied in atherosclerosis and coronary artery disease.

Contradictory results of microRNA-155 either promoting or preventing the pathophysiological process of atherosclerosis illustrate the complexity of this pleiotropic molecule.

Therefore, more comprehensive studies of the underlying mechanisms of microRNA-155 involvement in cardiovascular diseases are required.

Furthermore, a recent clinical trial of Miravirsen targeting microRNA-122 sheds light on exploiting microRNA-155 as a novel target to develop effective therapeutic strategies for cardiovascular diseases in the near future.
