a qPCR analysis of ectopic overexpression of miR-203 and miR-200c in 16B/TNF cells transfected with pre-miR-203, pre-miR-200c, or a combination of both miRNAs. Scramble oligonucleotides were transfected into 16B/TNF cells as a control. The relative amount of miRNAs in 16B/TNF cells transfected with pre-miRNAs was plotted as fold induction compared to that in 16B/TNF cells transfected with the scramble control 6 days post transfection. b The effect of miR-203 and miR-200c on the self-renewal of 16B/TNF cells was determined by a tumor sphere formation assay. *P< 0.01 compared to the scramble control by two-tailed Student’s t test. c Effect of miR-203 and miR-200c on migration of 16B/TNF cells was determined by transwell migration assay. *P< 0.05. d Effect of miR-203 and miR-200c on chemoresistance of 16B/TNF cells was determined by chemosensitivity assay. Five hundred cells were seeded in 96-well plates and treated with 40 µmol·L−1cisplatin (Cisp) or 25 µmol·L−1 methotrexate (Meth) for 4 days. *P< 0.05 compared to scramble. e The effect of miR-203 and miR-200c on the Notch pathway was determined by Western blotting using an antibody against the activated form of Notch1 protein (NICD). f Effect of miR-203 and miR-200c on the NICD downstream target Hes-1 was determined by qPCR. *P< 0.05 compared to the scramble control.
