The present study aimed to analyze the clinical significance of epithelial membrane protein 1 (EMP1) expression in ovarian serous tumors. A total of 84 cases of ovarian serous tumor (50 patients with malignant ovarian serous tumors and 34 patients with borderline and benign serous tumors) were retrospectively analyzed. Differences in the expression levels of EMP1 between the malignant and non-malignant tumor groups were evaluated by immunohistochemical staining.

In this study, we investigated the immunohistochemical expression of MMP-2 and MMP-9 and the correlation between the expression levels and prognostic clinicopathological parameters in 140 patients with invasive ductal carcinoma (IDC). The staining scores for MMP-9 were negative in 21 cases (15%), mild in 27 cases (19%), and strong in 92 cases (66%).

We aimed to analyze the role of plakophilins in breast cancer and its clinical progress. We have performed immunohistochemical study of the PKP1,2,3 in breast carcinoma.

We explored the relationship between plakophilins (PKP1, PKP2, PKP3) to gastric cancer via immunohistochemical techniques.
Methods: We compared the immunohistochemistry of PKPs in 34 gastric adenocarcinomas and 20 normal gastric tissues.
