Blocking CPT1A/CPT2 synergizes radiation in eliminating clonogenic RBCs cells. Representative images (A) of colonies generated with 1 × 103 MCF7, MCF7/C6, MCF7/C6 CPT1A KO, and MCF7/C6 CPT2 KO cells treated with or without 5 Gy IR, 40 μM ETX, or combined. All colonies were fixed at day 14 and quantitated (B). (C,D) Same as (A,B) except that MDA231, MDA231/C4 CPT1A KO, MDA231/C4 CPT2 KO, and MDA231/C4 cells were tested. In all experiments, n = 3; Error bars in (B,D) represent mean ± SD; significance was determined by one-way ANOVA test, **p < 0.01, ***p < 0.001.
