Target DEGs of miR-30c in our analysis were mostly related to the anti-apoptosis of abnormal tumor cells, including MAP3K9 in lung cancer (46), ST6GALNAC5 in prostate cancer (51), CSRNP3 in clear renal cell carcinoma (52), ZNF703 in breast tumors (53), and CLSPN in brain tumors (54). The gene discussed is ST6GALNAC5; the disease is clear cell renal carcinoma.
