The miR-125b/STARD13 regulatory axis has been confirmed in our previous studies [20–22, 26], and we indicate that STARD13 3’UTR suppresses breast cancer stemness by inhibiting YAP/TAZ activity through co-regulating Hippo and RhoA (Ras homolog gene family, member A) signaling [23]. This evidence concerns the gene STARD13 and breast cancer.
