Table 3 Immunohistochemical analysis as a function of age of subject

From: The serine protease prostasin (PRSS8) is a potential biomarker for early detection of ovarian cancer

  1. Tissue samples from healthy subjects, patients with benign lesions, and OVC patients were tested by immunohistochemistry for the appearance of PRSS8. Correlation analysis between PRSS8 and age of subject was performed
