Objectives: Benign prostatic hyperplasia and prostate cancer are important public health issues VSports手机版. However, histologic markers for these diseases are limited. .

Methods: Immunocytochemistry was used to analyze the cellular localization of AIbZIP, Cdc47, androgen receptor and estrogen receptor-beta markers. AIbZIP is a protein recently found to be more abundant in prostate cancer than in benign prostatic tissue, and Cdc47 is a cell proliferation-associated protein V体育安卓版. The localization and modulation of androgen receptor and estrogen receptor-beta through the carcinogenesis process have been examined in several studies but controversial results were obtained. These four proteins were evaluated as potential markers of prostatic diseases in 210 needle core biopsies, including normal prostate, benign prostatic hyperplasia, low-grade and high-grade prostatic intraepithelial neoplasia, and different Gleason grades of prostatic adenocarcinoma. .

Results: Androgen receptor and estrogen receptor-beta do not discriminate between benign and malignant specimens, while AIbZIP was able to distinguish between them. Cdc47, in contrast, discriminated not only between malignant and benign prostatic tissue, but also between benign prostatic hyperplasia and normal prostatic tissue. V体育ios版.

Conclusions: Cdc47 appears to be a sensitive marker of prostatic diseases since its expression gradually increased in parallel with the severity of the lesion. AIbZIP discriminated between benign tissue and cancer. AIbZIP and Cdc47 thus appear to be useful markers with diagnostic and prognostic values VSports最新版本. .
