Fig. 1From: Dysregulation of the miR-30a/BiP axis by cigarette smoking accelerates oral cancer progressionCSC significantly increased BiP expression in OSCC cells in dose- and time-dependent manners. A and B Dose-dependent effects (40 and 120 μg/ml) of CSC on the expression of BiP in YD38 and SCC25 cells were investigated by qRT-PCR and Western blot analysis. C and D Time-dependent effects of CSC (24 and 48 h) on the expression of BiP were examined by qRT-PCR and Western blot analysis. GAPDH was used as the internal control. All data are presented as the mean ± SEM. SEM, error bars. *P < 0.05 by one-way ANOVA followed by Bonferroni’s post hoc testBack to article page
