Fig. 3From: Role of RASEF hypermethylation in cigarette smoke-induced pulmonary arterial smooth muscle remodelingEffect of 5-Aza on CSE-induced HPASMCs proliferation and apoptosis changes. HPASMCs pretreatment with various concentration of 5-Aza (0, 0.5, 1, 2, 5, and 10 μM) for 48 h decreased DNMT1 protein levels (a, b) but did not affect the number of apoptotic cells (c). d CCK8 assay revealed pretreatment with 5-Aza (2 μM) inhibited CSE-induced increases in HPASMCs viability. Data are displayed as the mean ± standard error of the mean (n = 3); *P < 0.05, **P < 0.01Back to article page
