TRIM9 and triple-negative breast carcinoma: METTL14 activates miR-29c-3p through m6A and regulates the ubiquitination of pyruvate kinase isoform M2 (PKM2) mediated by the tripartite motif containing 9 (TRIM9), driving aerobic glycolysis of glucose and promoting the progression of triple-negative breast cancer (TNBC) (94).
