摘要:: To study the inhibition and significance of pigment epithelium-derived factor (PEDF) in the development and metastasis of prostate cancer.,The expression of PEDF was examined in the normal prostate tissue, benign prostatic hyperplasia, prostate cancer tissue and prostate cancer cell lines, PC-3 and Lncap by immunohistochemical SP method and Western blot. In combination with clinical data, statistical analysis was performed to evaluate the relation of the expression level of PEDF in prostate cancer and the relationship between different histological grades of prostate cancer.,In normal prostate tissue and benign prostate tissue, the expression of PEDF were elevated and it was far higher than the prostate cancer and prostate cancer cell line. The expression of PEDF and the pathological grade of prostate cancer were related to the differentiated carcinoma of prostate tissue, and the expression level of PEDF in poorly differentiated carcinoma below the highly differentiated carcinoma of prostate cancer. In metastatic prostate cancer, the expression of PEDF was lower than that of prostate cancer without metastasis (12% vs 43.1%).,The expression of PEDF and the incidence of prostate cancer have a negative correlation. The lower grade of prostate cancer cells, the less the tissue expression of PEDF and the higher tendency of invasion and metastasis.
