SLC4A4 and renal carcinoma: 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.
