Objective To establish two-dimensional electrophoresis profiles with high resolution and reproducibility from subcellular immortalized human endocervical cell (H8) and cervical cancer cell (Caski), and to identify the differential expressions of subcellular proteins (cytoplasmic, membranous and nuclear proteins). Methods H8 cells and Caski cells were incubated, and subcellular proteins of H8 cells and Caski cells were extracted and separated by means of immobilized pH gradient-based two-dimensional gel electrophoresis (2-DE). Then the selected differential protein spots were analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and SWISS-PROT database. Results We obtained well-resolved, reproducible 2-DE patterns; 6 differentially expressed cytoplasmic proteins and 3 differentially expressed membranous proteins and 9 differentially expressed nuclear proteins were defined in 2-DE gels. Conclusion Subcellular proteins of cervical precancerous lesion and cervical cancer are separated and analyzed by means of 2-DE and MALDI-TOF-MS/MS. There are significant differences between H8 cells and Caski cells. These data may be valuable for research of cervical precancerous lesion and cervical cancer, or as diagnostic markers and therapeutic targets for cervical cancer.
