RUNX1T1 and breast cancer: Third, Runx1t1 interacted with the transcription factor TCF4, and this Runx1t1–TCF4 complex positively regulated RBM24 protein expression by suppressing the expression of the RBM24 negative regulator miR-625-5p, resulting in the formation of a positive feedback loop driving elevated RBM24 expression and BC cell proliferation.
