Study on Different Proteomics of Denuded tongue coating / 国际中医中药杂志

ABSTRACT

Objective To investigate the microbiostatic mechanism of denuded tongue coating, Proteomic methods were used to find differential expression proteins in denuded tongue. Methods The total protein of normal or denuded tongue coating was separated by means of immobilized pH gradient-based two-dimensional gel electrophoresis (2-DE). The differential expression protein was analyzed by using ImageMaster 2D analysis software. Image analysis software was used for comparative analysis to find differential expression proteins; Mass spectrometry (mass spectrometry) was applied to get the corresponding peptide fingerprint (peptide mass finger print_ PMF). Search the database to identify differences in protein.Results Establish two-dimensional gel electrophoresis for normal and denuded tongue; Segregation analysis on four groups of proteome of tongue coating showed that gel could be detected in the protein spots at 1082=t=105 and 1143±140 respectively; Compared with normal group, there are eight points of protein expression being regulated upward and seven points down.Altogether 9 differences in protein expression were identified. Conclusion The sound resolution and repeatability Two-dimensional electrophoresis silver staining pattern were established; Some differences in protein expression related to denuded tongue were identified.
