Bufalin-induced apoptosis in bladder cancer cells through inactivation of Na+-K+-ATPase. (A) The protein expression of Na+/K+-ATPase α1 and α3 was detected by western blot analysis. GAPDH was used as a loading control. (B) The mRNA level of Na+-K+-ATPase α1 α2 and α3 was detected by qRT-PCR with specific primers of α1 α2 and α3 isoforms. GAPDH was used as a loading control. Data are presented as means ± SD of three independent experiments (*P<0.05 vs. control group). qRT-PCR, quantitative real-time PCR.
