Poly [ADP‐ribose] polymerase 1 (PARP‐1) expression level in pulmonary arterial smooth muscle cells (PASMCs) cultured under normal or hypoxic conditions after transfection. Other targets of miR‐223 were measured, including PARP‐1. A, After being cultured in either normoxic or hypoxic conditions for 36 h, Western blot analysis was performed to measure the protein level in all groups. B, Relative integrated density value (IDV) analysis of PARP‐1. All experiments were performed in triplicate. **P < 0.01 compared with the blank control in the normoxia treatment group; ^## P < 0.01 compared with blank control in the hypoxia group
