Abstract:
Objective To establish two-dimensional electrophoresis(2-DE) profiles with high resolution and reproducibility in analysis of hypothalamuses in the spontaneous hypertension rats(SHR) with hyperactivity of liver-yang to analyze the difference on the total proteins of hypothalamuses between the SHR and normal rats.Methods The total proteins of hypothalamuses in the rats were separated by immobilized pH gradient-based two-dimensional gel electrophoresis.With coomassie blue staining,the 2-DE image was analyzed by PDQuest 7.0 software.Results The average matching rate of the 2-DE images of hypothalamuses in the two kinds rats was 92% with good reproducibility.Proteins were mainly displayed at range of pI3-8,Mr(14.4～75) kD.The average spots in the SHR with hyperactivity of liver-yang and in the normal rats were 777?27 and 780?31 respectively.There were 22 spots of proteins up-regulated more than two times and 25 spots down-regulated more than two times in the SHR with hyperactivity of liver-yang than those of the normal rats.Conclusion There are 22 spots of proteins up-regulated and 25 spots of proteins down-regulated in the SHR with hyperactivity of liver-yang,which may be involved in the development of hyperactivity of liver-yang.
