FOXC2 and neoplasm: While FOXC2 orchestrates the mesenchymal component of the EMT program (Mani et al., 2007), Slug, ZEB2, and Twist1 repress E-cadherin expression, a fundamental event in EMT, as well as the expression of proteins of tight junctions, gap junctions, and desmosomes, contributing to the de-differentiated state of tumor cells and facilitating EMT (Peinado et al., 2007; Sanchez-Tillo et al., 2012).
