esiRNA to eri-1 and adar-1 genes improving high doses of c-myc-directed esiRNA effect on mouse melanoma growth inhibition
چکیده انگلیسی
Knockdown of c-myc expression via RNAi is expected to be an efficient approach to suppress tumor growth. In our preliminary study, we intraperitoneally injected different doses of c-myc-directed esiRNA (esic-MYC, c-myc-directed Escherichia coli expressed and enzyme digested siRNA) into C57BL6/6J mice with bearing B16 melanoma to investigate the inhibitory effect of esic-MYC on tumor growth. However, in high dose esic-MYC treatment groups, the tumor growth inhibition was less efficient than that of low dose treatment groups. Considering the negative regulation roles of eri-1 and adar-1 genes in RNA interference, we downregulated either/both of the two genes with c-myc gene by RNAi. Our results showed esiMERI-1 (esiRNA of mouse eri-1 gene) and esiMADAR-1 (esiRNA of mouse adar-1 gene) could rescue the tumor growth suppression in the high dose esic-MYC treatment groups obviously. The data strongly suggest that silencing of eri-1 and adar-1 homologs of human being should be concerned for cancer therapy by RNAi approach.
