For adhesion, well diversifying turned out genes encoding laminins (LAMB3, LAMC1), myosin-x (MYO10), and cadherin 18 (CDH18) which are associated with breast cancer invasion and metastasis (Arjonen et al. 2014; Polyak and Weinberg 2009), collagens (COL9A, COL12A) claudin-4 (CLDN4) was previously found to control proliferation, migration, and apoptosis of MCF7 cells (Ma et al. 2015). This evidence concerns the gene CLDN4 and breast cancer.
