miR-96 expression was upregulated in human bladder cancer (BC) tissues and could negatively regulate the expression of CDKN1A in both BC cells and tissues. a Using quantitative real-time PCR, we found that the expression level of miR-96 was significantly increased in BC tissues (n = 60) compared with that in NBTC tissues (n = 40; BC vs. NBTC: 3.69 ± 0.91 vs. 1.86 ± 0.52, P < 0.001); b the predicted CDKN1A 3′UTR-wild and CDKN1A 3′UTR-mut binding sequences in miR-96. c Co-transfection with miR-96 inhibitor significantly increased the luciferase activity of the reporter containing the wild-type 3′-UTR (*P < 0.05); d Western blot analysis also showed that the expression level of CDKN1A protein was significantly up-regulated in two human BC cell lines T24 and EJ transfected with miR-96 inhibitor (**P < 0.001); e using quantitative real-time PCR, we found that the expression level of CDKN1A mRNA was significantly decreased in BC tissues (n = 60) compared with that in NBTC tissues (n = 40; BC vs. NBTC: 2.42 ± 1.05 vs. 3.71 ± 0.90, P < 0.001); f Spearman correlation analysis showed the negative correlation between miR-96 and CDKNIA mRNA expression levels in human BC tissues (rs = −0.34, P = 0.01)
