Expression of TGFBR2 and IGF1R were altered following overexpression and knockdown of miR-320a. Normal human pulmonary fibroblasts were transfected with miR-320a mimics, miR-320a inhibitors, and scramble as control. a–c mRNA levels of TGFBR1, TGFBR2, and IGF1R were determined by SYBR Green real-time polymerase chain reaction analysis. d Protein was analyzed by western blot. Experiments were repeated at least 3 times. Values are means ± SD. *p < 0.05 versus scramble controls. **p < 0.01 versus scramble controls. ***p < 0.001 versus scramble controls
