Proteomic analysis of energy metabolism-related proteins of mice midbrain / 国际检验医学杂志

ABSTRACT

Objective To identify energy metabolism-proteins of mice midbrain by using the proteomic technique,and to investi-gate the relationship between these proteins and neural diseases.Methods Two-dimensional gel electrophoresis was used to sepa-rate totally soluble proteins extracted from mice midbrain.Some protein spots on two-dimensional gel electrophoresis gels were ana-lyzed by using matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS).Results 24 protein spots related with energy metabolism were separated by two-dimensional gel electrophoresis and identified by using MALDI-TOF MS successfully.Conclusion The establishment of energy metabolism-related proteins map of mice midbrain lays a foundation for the research on the involvement of these proteins in neural disease pathogenesis.
