Abstract:
:Chemoresistance is a major impediment to the successful treatment of cancer. It involves various mechanisms, including defects in the apoptosis program that is induced by anticancer drugs. To further explore the mechanisms underlying the development of chemoresistance in ovarian carcinoma after cisplatin (CDDP) treatment, we compared the effect of CDDP on expression of X-linked inhibitor of apoptosis protein (XIAP), a direct inhibitor of caspase-3, -7, and -9, Fas, Fas-ligand (Fas-L), and pro- and antiapoptotic proteins in a CDDP-sensitive human ovarian carcinoma cell line (2008) and its CDDP-resistant subclone (2008C13). In this article, we show that cisplatin treatment led to a differential expression of distinct apoptotic targets in the CDDP-sensitive cell line (2008) and its CDDP-resistant subclone (2008C13). The acquisition of cisplatin resistance was associated with the ability of the treated cells to enhanced expression of XIAP, whereas the death inducer Fas-L was abrogated in 2008C13 following treatment with CDDP. However, the CDDP-sensitive cells failed to activate XIAP but increased Fas-L expression, indicating that distinct regulatory mechanisms are operative. These findings suggest that the expression of XIAP and downregulation of Fas-L are linked to chemoresistance in ovarian carcinoma cells and may represent one of the potential antiapoptotic mechanisms involved during this process.
