U2AF2 and neoplasm: According to Spearman’s rho, we observed that total beta-catenin and U2AF65 expression are highly significantly correlated in cytoplasmic and nuclear tumor extracts (p = 5.7e-6 and p = 3.1e-6, respectively), while their expression correlated significantly in normal nuclear extracts (p = 0.0018), and showed no significant correlation in normal cytoplasmic extracts (p = 0.15).
