Prostate cancer is one of the most commonly diagnosed cancers in American men. Apelin is an endogenous peptide identified as the ligand of the G protein-associated apelin receptor. Apelin and apelin receptor have many tissues distribution and they participate in pathological processes, such as cancer. Apelin stimulates cancer angiogenesis. However, there are insufficient data in the literature regarding the role of apelin/apelin receptor in normal tissue, highgrade prostatic intraepithelial neoplasia, and prostatic adenocarcinoma tissues. Therefore, this study aimed to investigate the apelin and apelin receptor expression levels in tissues of normal prostate tissue, high-grade prostatic intraepithelial neoplasia, and prostatic adenocarcinoma.In this study, 38 samples of patients undergoing radical prostatectomy were used. Among 38 samples; 20 patients were with prostatic adenocarcinoma, 18 patients were with high-grade prostatic intraepithelial neoplasia and adjacent normal prostatic tissue areas. The immunolocalisation of apelin and apelin receptor in these tissues were determined immunohistochemically.Apelin and apelin receptor expressions were higher in prostatic adenocarcinoma than normal prostate tissue and high-grade prostatic intraepithelial neoplasia. Apelin receptor expression was also increased in high-grade prostatic intraepithelial neoplasia compared to normal tissue.Apelin and apelin receptor are increase in the process of prostate carcinogenesis. This increase may adversely affect the clinical course of prostate cancer patients by stimulating angiogenesis, which is important for invasion and metastasis in prostate cancer. |
