Expression of two potential downstream effectors of SOX11 signalling we recently identified in breast cancers cells, Mex3a and Rcor2, which have links to stem cell proliferation and reprogramming, respectively, were also substantially reduced in Brca1.3 cells with reduced Sox11 levels (Fig. 3D) (Barriga et al., 2017; Pereira et al., 2013; Yang et al., 2011). The gene discussed is SOX11; the disease is breast carcinoma.
