英文摘要:

Thioredoxin reductase (TrxR) in conjunction with thioredoxin (Trx) is a ubiquitous intracellular oxidoreductase system with antioxidant and redox regulatory roles. The properties of TrxR in combination with the functions of Trx position this system at the core of cellular thiol redox control and antioxidant defense. In some human tumors, the thioredoxin system is found overexpressed. Because of its role in stimulating cancer cell growth and as an inhibitor of apoptosis, the Trx system offers a target for the development of drugs to treat and prevent cancer. In a previous research, we successfully synthesized a novel organoselenium compound BBSKE(1,2-[bis(1,2-Benzisoselenazolone-3(2H)-ketone)]ethane, BBSKE, PCT: CN02/00412) targeting the TrxR, and it has demonstrated the inhibitory effect on the growth of a variety of human cancer cells from various organs. In this study, we investigated the inhibitory effect of BBSKE on TrxR activity in PC-3 and DU145 human prostate cancer cell lines, and its antitumoral effect on these two cell lines. Treatment of BBSKE inhibited the TrxR activity in both of the cell lines in a dose-dependent manner and it also inhibited the proliferation of these two cell lines in a dose-dependent manner. Cell cycle analysis showed S phase arrest in both of the cell lines following 48 h exposure to BBSKE. During the S arrest, analysis of cell cycle regulatory proteins demonstrated that BBSKE increased the protein levels of cyclinA, cyclinE, and P21, but decreased the levels of cyclinB1, cyclinD1, and Cdk4. Furthermore, BBSKE decreased the protein level of Bcl-2 but increased the level of Bax, and induced apoptosis in PC-3 and DU145 human prostate cancer cell lines. These results suggest that this novel TrxR inhibitor inhibits the proliferation of prostate cancer cells via S phase arrest and apoptosis in association with the regulation of multiple molecules in the cell cycle.
