Overexpression of GRK3, Promoting Tumor Proliferation, Is Predictive of Poor Prognosis in Colon Cancer

GRK3 expression and survival in colon cancer patients. (a) Immunohistochemical staining of GRK3 in tissue microarray (TMA). Elevated GRK3 expression in colon cancer tissues (2: well-differentiated case; 3: moderately differentiated case; and 4: low differentiated case) compared to adjacent normal mucosa with negative staining (1). (b) Kaplan-Meier survival curves of overall survival (top) and disease-free survival (bottom) according to GRK3 expression. Both overall survival rate and disease-free survival rate of GRK3-positive patients were significantly lower than those of the GRK3-negative patients (log-rank test, ).
