sub:provenance { sub:assertiondcterms:description "[For these studies we have used the A2780 ovarian cancer cell line and its chemoresistant derivatives A2780/DDP and A2780/ADR, providing evidence that: (i) the three cell lines are either scarcely sensitive (A2780 and A2780/ADR) or moderately sensitive (A2780/DDP) to the cytotoxic effects of TRAIL; (ii) the elevated c-FLIP expression observed in ovarian cancer cells is a major determinant of TRAIL resistance of these cells; (iii) proteasome inhibitors (PS-341 or MG132) are able to exert a significant pro-apoptotic effect and to greatly enhance the sensitivity of both chemosensitive and chemoresistant A2780 cells to TRAIL; (iv) proteasome inhibitors damage mitochondria through stabilization of BH3-only proteins, Bax and caspase activation and significantly enhance TRAIL-R2 expression; (v) TRAIL-R2, but not TRAIL-R1, mediates the apoptotic effects of TRAIL on ovarian cancer cells.].
