The dysregulation of circ_0068655, miR-498, and PAWR in cardiomyocytes subjected to hypoxic insult. A The expression of circ_0068655, miR-498, and PAWR in HCMs subjected to hypoxia treatment for 3, 6, and 12 h was evaluated by qRT-PCR. B The protein expression of PAWR in HCMs subjected to hypoxia treatment for 3, 6, and 12 h was evaluated by western blotting. The data are expressed as the mean ± SD. *p < 0.05; **p < 0.01
