PCBP1 and ovarian cancer: Among ovarian cancer cases, according to tumor node metastasis (TNM) classification, PCBP1 levels were especially lower in pT3 group (tumor with micro-metastasis of extra pelvic peritoneum confirmed by microscope) vs. pT1/2 group (tumor with or without pelvic spread) (Figures 1C,D), as well as the late clinical stage (stage III and IV) vs. early clinical stages (stage I and II) based on clinicopathologic features (Figures 1E,F).
