a, FOX-A1 expression in H1299 and SPC-A1 cell lines treated with different dose of Cisplatin. ⁎P < .05. FOX-A1 expression in cells treated with cisplatin at different time point was measured. ⁎P < .05. b, FOX-A1 expression in H1299 and SPC-A1 cell lines treated with different doses of PTX. ⁎P < .05, ⁎⁎P < .01. FOX-A1 expression in cells treated with PTX at different time point was measured.⁎P < .05, ⁎⁎P < .01. c, ABCB1 protein level in FOX-A1-overexpressed parental cell lines or in FOX-A1-downregulated docetaxel-resistant cell lines. Data are presented as means ± standard deviation.
