| Outline of Final Research Achievements |
Of all gastrointestinal carcinomas, pancreatic cancer (PaCa) has the most unfavorable prognosis. Anti-apoptotic members of the Bcl-2 protein family are often over-expressed in human cancers and are thought to mediate the resistance to chemotherapeutic drugs. Thus, a better understanding of the anti-apoptotic mechanisms and the development of potent and non-toxic strategies to overcome the pro-survival mechanisms in PaCa cells are of utmost importance to improve the outcome of PaCa patients.
In this reseach, we first showed that the expression and localization of anti-apoptotic Bcl-2 family proteins in PaCa cells. Then, we used siRNA targeting to Bcl-2, Bcl-xL, and Mcl-1 to confirm the importance of anti-apoptotic Bcl-2 family proteins in PaCa cell survival. Simultaneous knock-down of Bcl-xL and Mcl-1 induced apoptosis strongly through Bax/mitochondria pathway. These results suggest that Bcl-xL and Mcl-1, which are over-expressed in PaCa may be potential therapeutic targets.
