PRDX1 is an effective target enhancing cellular sensitivity to Ref-1 inhibitors in mouse PDAC cells. (A) PRDX1 knockdown efficiency in KC3590 Vector and C13 cell lines were greater than 80% comparing to scrambled control (SCR). Vinculin was used as loading control. (B–D) The cytotoxicity of Ref-1 inhibitors, APX3330, APX2009, APX2014 upon the condition of PRDX1 knockdown both in Vector and C13 were assessed. (E) cytotoxicity of RN7-58 was also evaluated along with Ref-1 inhibitors. Two-way ANOVA, **p < 0.01, ***p < 0.001. At least three independent experiments were performed (N = 3).
