Figure Lengend Snippet: Mod_asiRNA10-6 was more efficient at downregulating MYC, RRM2, RAD51 and PARP1 than the other siRNAs. (A) The relative mRNA expression of MYC, (B) RRM2, (C) RAD51 and (D) PARP1 in the MDA-MB-231 cell line. (E) The viability of the MDA-MB-231 cell line. (F) The immunoblots of MYC, RRM2, RAD51 and PARP1 in MDA-MB-231 cells and (G) MDA-MB-157 cell lines. (H) The viability of MDA-MB-157 cell line. For the modification patterns of each asiRNA used, refer to and . The dose of all siRNAs was 20 nM. Scramble: negative control asiRNAs (stabilized by modifications similar to those of the target asiRNAs). The relative mRNA expression of MYC was normalized to that of the endogenous control, HPRT1. *** p <0.001, **** p <0.0001, and ns: nonsignificant. All the experiments were done in triplicate (n=3).
Article Snippet: The following primary antibodies were used: recombinant anti-c-MYC antibody [Y69] (#ab32072, Abcam, Cambridge, MA, USA), anti-beta actin antibody (#ab8227, Abcam); anti-GAPDH antibody [EPR16891] as a loading control (#ab181602, Abcam), anti-RAD51 antibody ([EPR4030(3)] (#ab133534, Abcam), PARP1 (46D11) rabbit mAb (#9532, Cell Signaling Technology, Danvers, MA, USA) and RRM2 (E7Y9J) XP ® rabbit mAb (#65939, Cell Signaling Technology).
