CASC2 is down-regulated in hypoxia-induced PASMCs. a Expression of CASC2 was detected using qRT-PCR in PASMCs following O₂ exposure (21, 10, 3 and 1%) for 24 h. b CASC2 expression in PASMCs exposed to 3% O₂ for 0 h, 12 h, 24 h, 36 h and 48 h was measured by qRT-PCR. Experiments were performed in triplicate. *P < 0.05, ***P < 0.001
