Interestingly, analysis of a previously published dataset, in which 52 breast cancer cell lines were transcriptionally profiled [31], revealed significant correlation between expression of αv integrin and the mesenchymal markers N-Cadherin, Slug and Vimentin. Moreover, αv integrin was found to be highly expressed in mesenchymal breast cancer, with an invasive and metastatic phenotype. This evidence concerns the gene SNAI2 and breast cancer.
