Interestingly, one research paper described a subtype involved in the process of epithelial–mesenchymal transformation, characterized by the expression of genes encoding Desmocollin-3 (DSC3), Integrin Alpha-6 (ITGA6), Desmoplakin (DSP), and Cadherin-3 (CDH3), which correlates with recent findings describing the crucial role of CAFs in EMT in the cancer microenvironment [55]. This evidence concerns the gene ITGA6 and cancer.
