For the TCTP-mediated anti-apoptotic response to CTLs, we noted an increase in anti-apoptotic protein MCL-1, a signature molecule rendering tumor cells resistant to CTL-induced killing in previous studies12,14,19, in CT26 P3 cells as well as CT26 TCTP cells, relative to P0 or CT26-no cells, respectively (Supplementary Fig. 11c and Fig. 3a). This evidence concerns the gene DDX53 and neoplasm.
