A: Representative immunohistochemistry for HuR (upper panels) and TUBB3 (lower panels) on ovarian cancer samples. The panels on the left represent an ovarian cancer with a nuclear staining pattern for HuR (Hur N, see text) and a faint staining of TUBB3; the panels on the right represent a sample with a nuclear and cytoplasmic staining pattern for HuR (Hur C) and a marked staining of TUBB3 (magnification 400X). In insets, lower magnification is shown. B: Kaplan Meier analysis of overall survival (top) and progression free survival (bottom) for ovarian cancer patients according to TUBB3 protein expression. P values are added when the differences between the two curves are significant by Wilcoxon test.
