Super-Enhancer–Driven HCG20 Promotes Pulmonary Hypertension Through U2AF2 Splicing

Abstract excerpt

BACKGROUND: Pulmonary artery endothelial cell (PAEC) dysfunction is a pathological hallmark of pulmonary hypertension (PH). Yet, the roles of long noncoding RNAs (lncRNAs) driven by super-enhancers (SEs) in PAECs are not well understood. In this study, we focused on the PAEC-specific SE-associated lncRNA HCG20 (HLA complex group 20) and to elucidate its role and underlying mechanisms in the progression of PH....
