Pulmonary arterial hypertension (PAH) is characterized by progressive increase in pulmonary vascular resistance leading to right ventricular hypertrophy and failure. There is a need to find new biomarkers to detect PAH at its early stages and also for new, more effective treatments for this disease. miRNAs have emerged as key players in cardiovascular diseases and cancer development and progression and, more recently, in PAH pathogenesis. In this review, we focus on the potential of miRNAs as biomarkers and new therapeutic targets for PAH.

Achieving precise delivery of extracellular vesicles (EVs) to treat pulmonary arterial hypertension (PAH) remains challenging. Here, we propose a strategy using hypoxia-induced and glucuronic acid (GA)-modified mesenchymal stromal-cell-derived EVs (MSC-EVs) to enhance their functionalities and therapeutic targeting. The hypoxia-induced EVs (Hypo-EVs) exhibit enriched exosomal signatures and display heightened inhibition of the proliferation of pulmonary arterial smooth muscle cells (PASMCs) compared to normoxic EVs (Norm-EV).

Pulmonary arterial hypertension (PAH) is a rare progressive disease characterized by pulmonary artery vascular remodeling, increased vascular resistance, and subsequent right ventricular hypertrophy and right heart failure. It is triggered by disrupted transforming growth factor (TGF)-β signaling, including loss-of-function mutations in the bone morphogenetic protein (BMP) receptor 2. Emerging treatments aim to inhibit elevated TGF-β levels or enhance diminished endothelial BMP signaling.

Acute pulmonary embolism (APE)-induced pulmonary artery hypertension (PAH) is a fatal disease. The miR-34-3p/DUSP1 has inhibitory effects on the thickening of the pulmonary arterial walls in APE rats and the proliferation of platelet-derived growth factor-BB (PDGF-BB)-induced human pulmonary arterial smooth muscle cells (hPASMCs). Herein, the lncRNAs regulating the miR-34a-3p/DUSP1 axis in APE and PAH are further explored in vitro and in vivo.

The pathogenesis of pulmonary arterial hypertension (PAH) is closely linked to the abnormal proliferation of pulmonary artery smooth muscle cells. Studies have demonstrated that microRNAs play pivotal roles in the progression of pulmonary hypertension. We found that microRNA-637 (miR-637) and microRNA-661 (miR-661) are expressed at low levels in the serum of PAH patients.

Objectives: This study explored the expression and diagnostic value of differentially expressed miR-3591-5p in congenital heart disease-associated pulmonary arterial hypertension (CHD-PAH).
Methods: A total of 110 CHD patients were divided into four groups based on their mean pulmonary artery pressure (PAPm). The plasma miR-3591-5p expression was determined by reverse transcription polymerase chain reaction.
