The most upregulated genes that were associated with the invasion of cells and ILK and integrin signaling are breast cancer antiestrogen resistance 3 (BCAR3), Cav1, α-actinin-1 (ACTN1), paxillin (PXN), and parvin-β (PARVB), with most of them being involved in cytoskeleton organization, cell adhesion, and focal contacts formation. This evidence concerns the gene ACTN1 and cancer.
