title: [Establishment of protein expression profile of laser capture microdissection-purified nasopharyngeal carcinoma tissue].
abstract: OBJECTIVE
  To establish the protein expression map of nasopharyngeal carcinoma (NPC), and provide a basis for proteomic study of NPC.
  
  
  METHODS
  Laser capture microdissection (LCM) was used to isolate cancer cells from NPC tissues. Two-dimensional gel electrophoresis(2-DE) was used to separate the total proteins of LCM purified NPC cells. Matrix-assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF-MS) was performed to identify the proteins, and bioinformatics was used to construct the 2-DE database of NPC proteome.
  
  
  RESULTS
  A 2-DE reference map of NPC was established. On the 2-DE map, a total of (1 312+/-30) protein spots were detected, and 427 protein spots representing 241 non-redundant proteins were identified. The 2-DE database of NPC proteome was constructed. These data could be accessed at our website (http://www.xyproteomics.org).
  
  
  CONCLUSIONS
  A protein expression profile of LCM purified NPC tissues has been established for the first time, which provides useful information and source for proteomic study of NPC.
