Abstract

Objective: Identification of proteomic alterations in epithelial ovarian tumorigenesis may facilitate the understanding of progression of this disease. Methods: Specific protein peak patterns were identified in 20 microdissected epithelial ovarian tumors (13 epithelial ovarian cancers (EOCs) and 7 low malignant potential (LMP) tumors), as well as in the matched normal cells. Protein profiles were generated by surface-enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS) from all the different types of cells. Results: Among seven protein peaks from EOC cells, six were significantly increased while one was decreased compared with normal cells, and three peaks from LMP cells were markedly increased while one was decreased compared with normal cells. Conclusions: The combination of SELDI and laser capture microdissection (LCM) is effective in finding the key molecules in ovarian tumorigenesis. Further identification of these protein peaks is important and these malignant protein signatures lend themselves to identification of populations at high-risk for EOC and for monitoring response to EOC chemopreventive agents.
