LncRNA CASC2 inhibited hypoxia-induced cell proliferation in rat pulmonary arterial tissues. (a) The mRNA expression of PCNA was detected by qRT-PCR in rats′ PAs tissues. (b, c) The protein expression of PCNA was detected by western blot analysis in rat pulmonary arterial tissues. ##p < 0.01, compared with normoxia group. ###p < 0.001, compared with normoxia group. **p < 0.01, compared with hypoxia + pcDNA3.1 group
