Similarly, miR-223-3p, highly expressed in cancer renal tissue and positively correlated with ccRCC staging and progression, downregulates at protein level the solute carrier family 4, member 4 (SLC4A4), which also regulates KRAS, therefore favoring proliferation and metastasis [114]. The gene discussed is SLC4A4; the disease is nonpapillary renal cell carcinoma.
