Salidroside suppresses PI3K and Akt protein expression in bladder cancer cells. (A) Salidroside suppresses PI3K and Akt protein expression, as revealed via western blotting. The protein expression levels of (B) PI3K and (C) Akt were quantified. *P<0.05, vs. the control group. PI3K, phosphoinositide 3-kinase; Akt, protein kinase B; p-, phosphorylated.
