Similar methods were applied to verify the downstream modulation, including tumor weight and size (Figure 6A‐C), quantitative RT‐PCR examination of miR‐193a‐3p and KRAS mRNA (Figure 6D,E), western blotting of KRAS protein level (Figure 6F,G), and H&E/Immunohistochemical staining (Figure 6H,I) after 28‐day xenograft growth in the mice. Here, KRAS is linked to neoplasm.
