ACKR3 and breast cancer: Although the precise mechanism of miR-101-3p in BC regulation is not entirely clear, miR-101-3p was observed to inhibit proliferation, invasion, and metastasis via targeting Stathmin1 (STMN1) and C-X-C chemokine receptor type 7 (CXCR7)(Wang et al., 2012; Li et al., 2015) and promote apoptosis by targeting Janus kinase 2 (JAK2) in BC cells (Wang et al., 2014).
