Abstract:
Aim To study the molecular basis of protection on myocardial ischemic injuries of total flavones of choerospondias axiaris fructus(TFC). Methods The microarray analysis for the protein expression in myocardium provide a strong tool to explore the key protein candidates involved in the pathogenesis of ischemic injury.Surface enhanced laser desorption/ionization(SELDI) mass spectrometry with protein chip IMAC3,SAX2 and NP20 was used to compare the differentially expressed protein in TFC-treated and untreated ischemic myocardium in rats and the results were analysized with Proteinchip Software 3.0.2.Results Seven differentially expressed proteins were indentified in TFC treated myocardium.These differential effects correlated with the expression of five downregulated proteins and two upregulated proteins,and four of them were discovered on the IMAC3 chip and one of them was discovered on the SAX2 chip.Conclusions The myocardial protection of TFC may be mediated by the differential expression of these proteins which could be the key protein candidates for further investigation.
