In prostate cancer, a strong positive correlation was observed between high levels of E-cadherin protein expression and CDH1 transcript levels (Spearman R = 0.9429; P = 0.0167) (Significant regression equation: F (1, 4) = 9.654, P= 0.036, R2 = 0.7071). The gene discussed is CDH1; the disease is prostate cancer.
