(1). Driving breast cancer cells into quiescence through reducing the expression of CXCL12 (2). The DTCs can promote BMSCs to express abundant distinct miRNAs such as miR222/223 and miR23b, all of which can result in the dormancy of certain DTCs by suppressing the TGF-b pathway. This evidence concerns the gene TGFB1 and breast carcinoma.
