The phosphorylated YAP then moves from the cytosol to the nucleus, where it promotes the expression of genes that are tangled with contact inhibition of BC stem cells, including ankyrin repeat domain 1 (ANKRD1), connective tissue growth factor (CTGF), cysteine-rich angiogenic inducer 61 (Cyr61/CCN1), and inhibin βA (INHBA) [77]. This evidence concerns the gene CCN1 and breast cancer.
