Fig. 5: circIFNGR2 sponges miR-30b to reduce KRAS expression.

a RT-qPCR was used to detect the relative expression level of WT-KRAS in the indicated cells. b Western blotting was performed to determine the protein expression of WT-KRAS in the indicated cells c, e RT-qPCR was used to detect the relative expression level of WT-KRAS in the indicated cells. d, f Western blotting was performed to determine the protein expression of KRAS and its downstream proteins. The error bars represent the means ± SDs from three independent experiments. *p < 0.05, **p < 0.01, ***p < 0.005.
