OBJECTIVE: To study the proteins related to paclitaxel-resistant of ovarian cancer cell line. METHODS: The total proteins of paclitaxel-resistant and paclitaxel-sensitive human ovarian cancer cell lines were separated by 2-dimensional gel electrophoresis (2-DE). The differentially expressed proteins were analyzed using image analysis software. The differential proteins were identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Western blot was used to determine the differential expression levels of the 2 proteins. RESULTS: Forty differentially expressed proteins were found by image analysis software, and 24 differential proteins were identified by mass spectrometry. These proteins included proliferation cell nuclear antigen (PCNA), nm23, prohibitin (PHB), annexin, alpha-enolase, heat shock protein (HSP), and so on. CONCLUSION: Twenty-four proteins in human ovarian cancer cell lines of paclitaxel-resistant and paclitaxel-sensitive are found by proteomic techniques, which may be involved in the paclitaxel-resistance of human ovarian cancer cells.
