Some genes associated with cell adhesion were analyzed from this radiation- and estrogen-induced experimental breast cancer model, including E-cadherin gene CDH1, DSC3, GJA1, the Integrin alpha 6 gene ITGA6, the Integrin beta 6 gene ITGB6, the Keratin genes KRT14, KRT16, KRT17, KRT6B, and LAMB3. Here, ITGA6 is linked to breast cancer.
