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). This evidence concerns the gene WNT5A and invasive breast carcinoma.
