Abstract: To screen out cervical carcinoma related protein markers by a comparative proteome analysis. Methods: Twodimensional gel electrophoresis maps of the proteins extracted from H8 and Caski were applied respectively. The differential expression proteins were identified by MALDITOFMS; Western blot was used to detect M2PK expression from normal cervix and cervical carcinoma tissues. Results: The 2DE maps of H8 cells and Caski cells were established, and the protein M2PK was identified successfully. Western blot confirmed differential expression of M2PK on normal cervix and cervical carcinoma tissues. Conclusion: These proteins from H8 cells and Caski cells are differentially expressed. It will be helpful to find new molecular markers for early diagnosis and treatment of cervical cancer.
