TCF4 and breast cancer: Although the direct relationship between miR-625-5p and BC has not been verified yet, some studies have found that miR-625-5p can form a feedback channel with Runx1t1/TCF4 and promote BC progression under the action of RBM24 [9], which also preliminarily reveals the possible close relationship between miR-625-5p and the occurrence and development of BC.
