RT Journal Article T1 VE-cadherin promotes vasculogenic mimicry by modulating kaiso-dependent gene expression. A1 Delgado-Bellido, Daniel A1 Fernández-Cortés, Mónica A1 Rodríguez, María Isabel A1 Serrano-Sáenz, Santiago A1 Carracedo, Arkaitz A1 Garcia-Diaz, Angel A1 Oliver, F Javier AB Aberrant extra-vascular expression of VE-cadherin (VEC) has been observed in metastasis associated with vasculogenic mimicry (VM); however, the ultimate reason why non-endothelial VEC favors the acquisition of this phenotype is not established. In this study, we show that human malignant melanoma cells have a constitutively high expression of phoshoVEC (pVEC) at Y658; pVEC is a target of focal adhesion kinase (FAK) and forms a complex with p120-catenin and the transcriptional repressor kaiso in the nucleus. FAK inhibition enabled kaiso to suppress the expression of its target genes and enhanced kaiso recruitment to KBS-containing promoters. Finally we have found that ablation of kaiso-repressed genes WNT11 and CCDN1 abolished VM. Thus, identification of pVEC as a component of the kaiso transcriptional complex establishes a molecular paradigm that links FAK-dependent phosphorylation of VEC as a major mechanism by which ectopical VEC expression exerts its function in VM.
