ABSTRACT
Cisplatin is one of the most widely used anticancer agents, but a major problem for successful chemotherapy is the development of drug resistance of tumor cells against cisplatin. Resistance to cisplatin is a multifactorial problem. A method to detect and identify intracellular cisplatin-protein adducts was developed using a fluorescent carboxyfluorescein-diacetate-labeled cisplatin analogue (CFDA-cisplatin), 2DE, and ESI-MS/MS. We identified several CFDA-cisplatin-protein adducts including members of the protein disulfide isomerase family (PDI). These are the first results of the detection of intracellular CFDA-cisplatin-protein adducts, which may help to understand the resistance mechanism of cisplatin.
