Contribution of p53 to EMT-related transcriptional factors in A549 cells under miR-34a overexpression. The cells were transfected with NC (20 pmol/well) or miR-34a mimic (20 pmol/well) under the control siRNA (siCont.; 10 pmol/well) or sip53 (10 pmol/well) for 24 h. After 24 (A) or 72 h (B), the mRNA expression levels of SNAIL, SLUG, ZEB1, and TWIST were measured by real-time PCR. Each value represents the mean ± S.E.M. (n = 3). * p < 0.05, ** p < 0.01, significantly different from miR-34a mimic under siCont. condition.
