Abstract:

Background: In cancers of prostate, breast, oropharynx, lung, hypopharynx and skin, human tissue kallikreins has been demonstrated as a main role in these problems. There are many research works in which some human tissue kallikreins are expressed in salivary glands. In the present study, the main goal was to determine expression of human tissue kallikreins 4, 8, 10, 11 and 13 in pleomorphic adenomas and mucoepidermoid carcinomas. Methods: Sixty-six specimens (45 cases of pleomorphic adenomas and 21 cases mucoepidermoid carcinomas) were selected for final analysis by immunohistochemistry. For doing association test, clinical parameters obtained from the patients’ medical charts, which included age, gender were used and the nonparametric tests employed for statistical analyses. Results: The expression of human kallikreins 4, 8, 11 and 13 was more prominent in benign and malignant tumors compared to that in normal tissues and the difference was significant. In addition, the expression of human kallikreins 4, 8, 10 and 11 in malignant tumors was more than that in benign tumors, with statistically significant differences. Conclusion: The differences in the levels of human kallikreins 4, 8, 11 and 13 suggest that kallikreins may benefit in determining tumor behavior of salivary gland tumors.

Immunohistochemical Expression of p53 and bcl2 in Colorectal Adenomas and Carcinomas Using Automated Cellular Imaging System

Background & Objective: The current approaches to reduce the risk of colorectal carcinoma are through the detection and removal of the precursor lesion” adenomatous polyps”. The study was conducted to evaluate the immunohistochemical expression of p53 and bcl2 in colorectal adenomas and carcinomas. Patients and Methods: A total of 86 cases, 33 colorectal adenomas, 33 colorect...

Prognostic implications of the immunohistochemical expression of human kallikreins 5, 6, 10 and 11 in renal cell carcinoma.

Human kallikreins 5, 6, 10 and 11 (hK5, 6, 10 and 11) are expressed by many normal tissues, and it has been suggested that they may represent candidate tumor-diagnostic or -prognostic markers. In patients with renal cell carcinoma (RCC), outcome is unpredictable despite the use of conventional prognostic factors. The aim of this study is to evaluate the immunohistochemical expression and the pr...
