Objective:To study the inhibitory effect of matrine on bladder cancer cell growth and invasion in vitro through PI3K/AKT signaling pathway. Methods:Human T24 bladder cancer cell lines were cultured and treated with different doses of matrine(0.25 mg/mL,0.5 mg/mL and 1.0 mg/mL) as well as 20 μmol/L PI3K inhibitor LY294002 for 24 h,and the cell proliferation activity,the number of invasive cells as well as the expression of p-PI3K,p-AKT,proliferation genes and invasion genes were determined. Results:Different doses of matrine could decrease the cell viability value,the number of invasive cells as well as the expression of p-PI3K,p-AKT,MMP2 and MMP9,and increase the expression of p16,p21 and p27 in dose-dependent manner; p16,p21 and p27 expression in cells of 20 μmol/L LY29002 group were significantly higher than those of 0 μmol/L LY29002 group while MMP2 and MMP9 expression were significantly lower than those of 0 μmol/L LY29002 group(P<0.05). Conclusions:Matrine can inhibit bladder cancer cell proliferation and invasion in vitro and regulate the expression of cell cycle-inhibiting molecules and invasion-related genes through PI3K/AKT signaling pathway.
