Objective:The study aims to screen chemosensitivity-associated proteins in colorectal carcinoma tissues by using two-dimensional gel electrophoresis (2-DE) and mass spectrometry,then identify some differentially-expressed proteins. Methods:The patients with advanced colorectal carcinoma were confirmed by clinical diagnosis. Fresh carcinoma specimens were collected by biopsy and preserved in liquid N2. The tissues were classified into two groups: high sensitivity group (HS) and low sensitivity group (LS) based on drug sensitivity test. The total proteins were extracted and separated by 2-DE. The images were composed, compared, and differentially analyzed to identify the proteins with differential expression in HS and LS groups. Then the differentially-expressed protein spots were incised from the gels and digested by trypsin. The peptide mass fingerprintings (PMF) was acquired after matrix assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) and the proteins were identified by data searching in the Mascot database. Two proteins with differential expression were detected by Western blotting.Results:The 2-DE spectrum of HS and LS groups were established. Most protein spots were distributed in the area with pH 4-8 and relative molecular weight of (20-100)×10~3. The average number of the protein spots was 842±23 in HS group and 793±19 in LS group,respectively. The mean matching rate was 90.7%. The number of differentially-expressed dots between HS and LS group was 79.00±13.56. Thirty protein dots were selected for mass spectrum and bioinformatic analysis, and 9 proteins were identified. Conclusion:Colorectal carcinoma with different chemosensitivity had differential protein expression profiles. The differentially expressed proteins may be associated with chemosensitivity and could be used for prediction of chemosensitivity of colorectal carcinoma.
