Abstract

Background: Potential targets for prostate cancer therapy are urgently needed for curative of patients. Cyclosporine-A (CsA), an immunosuppressive and a selective cyclooxygenase-2 (COX-2) inhibitor, exerts antitumor activity. However, the molecular effects of CsA is not fully understood in prostate cancer. In this research, we sought to determine role and mechanism of CsA in prostate cancer. Materials and methods: PC3 and DU145 cells were treated with CsA time (12, 24, 48 h) and dose dependent (2.5, 10, 25 mu M) and cell survival, migration, colony formation, expression of apoptosis related proteins/genes using MTT assay, scratch assay, Western blotting/qPCR. At the same time, cells treated with CsA to test on the effects of COX-2 promoter activity using luciferase reporter plasmid. Lastly, functional role in the CsA treatment prostate cancer cells were interrogated for relationship of TGF beta, Akt, caspases and COX-2. Results: These study findings provided direct evidences that the CsA induced apoptosis and downregulated migration. Conclusions: CsA downregulated Akt as well as COX-2 and upregulated TGF beta, resulting in the suppression of cell migration which was augmented a potential therapeutic of CsA in prostate cancer cells.
