ZIC2 knockdown sensitized NCI-H1299 cells to cisplatin and paclitaxel treatment. (A) Effects of ZIC2 knockdown on the response to different concentrations of cisplatin in NCI-H1299 cells were evaluated by CCK-8 assays. (B) Effects of ZIC2 knockdown on the response to different concentrations of paclitaxel in NCI-H1299 cells were evaluated by CCK-8 assays. (C) Colony formation assays were conducted to evaluate the effects of ZIC knockdown on cisplatin resistance in NCI-H1299 cells; two concentrations (10 and 20 mM) were selected according to the results of CCK-8 assays. (D) Colony formation assays were conducted to evaluate the effects of ZIC knockdown on paclitaxel resistance in NCI-H1299 cells; two concentrations (0.01 and 1 mM) were selected according to the results of CCK-8 assays. (E) Apoptosis rates of ZIC2-KD and corresponding parental NCI-H1299 cells under different concentrations of cisplatin treatments were determined by FACS. (F) Apoptosis rates of ZIC2-KD and corresponding parental NCI-H1299 cells under different concentrations of paclitaxel treatments were determined by FACS.
