Twist knockdown reduces cell growth potential in CisR OC cells. (A) Western blot analysis for DNA repair proteins, PARP1 and XRCC1. (B) The cell survival analysis assayed by clonogenic assay. (C) Western blot analysis for expression of ER stress signaling proteins, GRP78, cleaved ATF-6 and CHOP. Parental: non-transfected parental cells; siNC: cisplatin resistance cells transfected with non-targeting negative control siRNA; siTwist: cisplatin resistance cells transfected with Twist siRNA. Values were represented as mean ± SD. #
p < 0.05, compared with the parental group and * p < 0.05, compared with siNC group.
