Proteomics-based approach was applied to analyze and compare the difference of proteins among human nasal inverted papilloma (NIP), nasal polyposis and normal nasal mucosa, in order to screen different proteins as marker. The total proteins of NIP, nasal polyposis and normal nasal mucosa were separated by two-dimensional gel electrophoresis (2-DE). Protein image obtained by using the gel of Calibrated GS-800 Densitometer system, and determined different protein spots. Six differential proteins between NIP and nasal polyp tissue were identified, which were galectin-1, Manganese-superoxide dismutase, galectin-7, trichostatin A, prohibitin and transferring. All of them were increased in NIP. Six differential proteins were possibly involved in NIP, which provided a new way for discriminating NIP from nasal polyposis. The data would be good for the establishment of NIP protein 2-DE map.
