MIOS and pulmonary arterial hypertension: In this study, the role of YULINK in cell migration, proliferation and glycolysis in PASMCs treated with PDGF or PASMCs derived from rats with MCT-induced PAH was examined, and the results indicated that the level of YULINK expression was correlated with cell migration and proliferation in PASMCs treated with PDGF or PASMCs derived from rats with MCT-induced PAH (PAH-PASMCs).
