DDR1 and cancer: These antigens are involved in multiple, critical cancer pathways such as tissue invasion and metastasis (P5; Integrin β8 subunit precursor, P14; Junction plakoglobin and P15; EDDR1), evading apoptotic cell death (P3; BAP31) and providing the ability to resist anti-growth signals (P7; Abl binding protein C3)[5-9], with resultant specific immune responses expected to reduce the chance for progression of tumor escape variants[9,10].
