To determine whether SLC4A4 could reverse the oncogenic effects of miR-223-3p, we co-transfected renal cancer cells with miR-223-3p mimics and SLC4A4. The mRNA levels of miR-223-3p and SLC4A4 are shown in Figure 7A and 7B, while the protein levels of SLC4A4 and KRAS are shown in Figure 7C. This evidence concerns the gene KRAS and renal carcinoma.
