| Research Abstract |
RCAS1 can induce apoptosis in immune cells including peripheral lymphocytes and natural killer cells after converted to a secreted type by ectodomain shedding. Because RCAS1 not only helps tumor cells to evade immune surveillance but also induces cancer stromal tissue remodeling, RCAS1 is believed to exaggerate aggressive characteristics of human malignancies. Clinically, RCAS1 expression correlates with several pathological variables including tumor size, stage, invasion depth, and lymph node metastasis and is a negative predictor of overall survival in 15 different kinds of cancer. Novel therapeutic strategies against cancer are now under development by targeting an intriguing biomarker RCAS1.
