摘要: AIM: To identify the differential proteins associated with colorectal cancer genesis and hepatic metastasis. METHODS: Hydrophobic protein samples were extracted from normal mucosa, primary lesion metastatic foci of cancer. With two-dimensional electrophoresis image analysis, differentially expressed spots detected, identified by matrix assisted laser desorption/ionization-time flight-mass spectrometry peptide mass fingerprint analysis. RESULTS: Significant alterations in number expression levels discovered foci, a was lost 25-40 ku, but increased 14-21 compared mucosa. Nine identified. Three metastasis, recognized as calmodulin, ribonuclease 6 precursor mannosidase-α. Proapolipoprotein progressively mucosa to metastasis. The beta-globin found tumor, lesion. Cdc 42, GTP-binding protein, C4 cancer, M7 M9 metastasis had less homology database. CONCLUSION: Variations hydrophobic initiation are significant can be observed electrophoresis. mannosidase-α is proapolipoprotein enhanced which 42 abnormally Protein C4, may
