Other in vitro studies of breast cancer cells have led to the suggestion that WNT‐5A reduces the metastatic capability of invasive breast cancer by enhancing adhesion and decreasing migration (Dejmek et al., 2003; Jiang et al., 2013; Jonsson and Andersson, 2001; Medrek et al., 2009; Roarty and Serra, 2007; Safholm et al., 2006). Here, WNT5A is linked to breast cancer.
