A Olaparib inhibited the PI3K/AKT pathway in STAD cells, and up-regulation of ClC-3/SGK1 axis enhanced olaparib-induced PI3K/AKT pathway inhibition (n = 3). vector, empty vector-transfected cells; ClC-3 ClC-3 overexpression cells. B Nude mice were subcutaneously injected with SGC-7901 cells, and representative images of STAD tumor xenografts were exhibited (n = 7 mice/group). C Down-regulation of ClC-3 attenuated olaparib-induced tumor weight reduction. D Down-regulation of ClC-3 attenuated olaparib-induced tumor volume decrease. E The expression of PCNA and MMP2 in tumor tissues was detected by IHC staining. F The proposed mechanism model of olaparib in STAD growth and migration. *P < 0.05.
