Beta1 subunit of integrin is an adhesion molecule involved in cell survival and cancer resistance to radiotherapy and chemotherapy [2-4], sharing common downstream signaling elements with EGFR, such as the phosphatidylinositol 3-kinase/AKT and extracellular signal-regulated kinase-1/2 (ERK1/2) pathways [5-9]. Here, MAPK3 is linked to cancer.
