TP inhibits docetaxel-induced autophagy via mTOR signaling pathway activation in PC3 and DU145 cells. a PC3 cells were cultured in Doc (100 ng/ml) for 4 h with or without TP pretreatment (20 μM, 30 min), and western blot was used to detect protein expression. b PC3 and DU145 cells were cultured in Doc (100 ng/ml) for 4 h with a different concentration of TP pretreatment (30 min), and western blot was used to detect protein expression. c PC3 and DU145 cells were cultured in Doc (100 ng/ml) for 4 h with or without TP (20 μM, 30 min) or RAPA (100 nM, 30 min), and western blot was used to detect protein expression. *P < 0.05, **P < 0.01
