RHOA and pulmonary arterial hypertension: [312] found that PAXIP1‐AS1 expression in lung tissue and serum of MCT‐induced PAH rats and hypoxia‐induced HPASMCs was significantly increased, promoting cell viability and migration of HPASMCs through the ETS1 (ETS proto‐oncogene 1, transcription factor)/WIPF1 (WAS/WASL interacting protein family member 1)/RhoA pathway [312].
