title: Over-expression of COX-2 induces human ovarian cancer cells (CAOV-3) viability, migration and proliferation in association with PI3-k/Akt activation.
abstract: COX-2 is involved in several pathological processes. The action of COX-2 on human ovarian cancer cell line (CAOV-3) and relative signal pathway has not been demonstrated. We explored the effects of COX-2 on the CAOV-3 viability and migration, moreover the proliferation of CAOV-3, and then ascertained the roles of PI3-k/Akt in these processes. The results showed that COX-2 increased the cells viability, migration and augment the number of CAOV-3. LY294002 could reduce COX-2 induce cells viability, migration and proliferation. These data indicate that COX-2 induce cells viability and migration, moreover promote the proliferation of CAOV-3 via PI3-k/Akt signal pathway.
