Immunohistochemical evaluation of PCNA, p53, HSP60, HSP10 and MUC-2 presence and expression in prostate carcinogenesis

Anticancer Res. Mar-Apr 2003;23(2B):1325-31.

Abstract

Background: The study of the expression of different biological markers in non-neoplastic, pre-neoplastic and neoplastic lesions of prostate could help to better understand their role in carcinogenesis and to find new diagnostic and prognostic tools.

Materials and methods: In the present work we evaluated, by immunohistochemistry, the presence and the expression of PCNA, p53, HSP60, HSP10 and MUC-2 in a series of nodular hyperplasia, low- and high-grade prostatic intraepithelial lesions and adenocarcinomas.

Results: Our data confirmed that: 1) PCNA expression could be related to the grade of progression of cancer; and that 2) p53 mutation could be a late event in prostate carcinogenesis. Moreover, we reported that: 1) HPS60 and HPS10 were overexpressed early in prostate carcinogenesis; and that 2) MUC-2 is absent in both tumoral and non-tumoral prostatic tissue.

Conclusion: We suggest the further examination, by molecular and genetic studies, of the role of HSP60 and HSP10 during carcinogenesis of the prostate as well as of other organs.
