Abstract
The role of miRNAs in PAH is fast expanding, and it is increasingly difficult to identify which molecules have the highest translational potential. This review discusses the challenges in miRNA analysis and interpretation in PAH and highlights 4 promising miRNAs in this field. Additional pre-clinical studies and clinical trials are urgently needed to bring miRNAs from the bench to the bedside soon.
Pulmonary arterial hypertension (PAH) is a rare, chronic disease of the pulmonary vasculature that is associated with poor outcomes. Its pathogenesis is multifactorial and includes micro-RNA (miRNA) deregulation. The understanding of the role of miRNAs in PAH is expanding quickly, and it is increasingly difficult to identify which miRNAs have the highest translational potential. This review summarizes the current knowledge of miRNA expression in PAH, discusses the challenges in miRNA analysis and interpretation, and highlights 4 promising miRNAs in this field (miR-29, miR-124, miR-140, and miR-204).
