Abstract:

In order to identify potential protein targets involved in colorectal cancer(CRC), we used a liquid chromatography coupled with mass spectrometry(LC-MS)/MS-based proteomics approach to characterize global protein expression patterns in malignant tissues and their adjacent healthy tissues from Dukes C stage CRC patients. A total number of 34 differentially expressed proteins were detected and identified by LC-MS/MS and database searching, which are supposed to be relevant to progression of colorectal tumor. Among these proteins, nucleophosmin 1(NPM1) was found to be remarkably up-regulated in colorectal carcinoma tissues, as compared with that in their normal counterparts. The results presented here could provide clues to elucidate the pathological significance of NPM1 in regulation of carcinogenesis of Dukes C stage colorectal tumors.
