STARD13 and breast cancer: It has also been shown that STARD13 exerts its function in BC through its participation in many ceRNETs, such as the one involving a positive TGF-β/miR-9 regulatory loop mediated by the STARD13/YAP axis [216], the one involving hsa-miR-21-3p [217], or even the more complex network that involves five different miRs and that controls YAP/TAZ nuclear accumulation and transcriptional activity via modulation of Hippo and Rho-GTPase/F-actin signaling pathways [218].
