ABSTRACT
Objective To observe the effects of therapy of tonifying kidney and replenishing essence on protein expression profile in testes of aged rats.Methods Twenty male SD rats with 22 months old were equally randomized into the blank control group and the treatment group.The treatment group received gastric gavage of herbs at the dose of 0.05g?kg-1.d-1,which has the actions of tonifying kidney and replenishing essence.The treatment lasted 60 days.After treatment,the right testes were taken out from the rats,and the differentially expressed proteins in the rats testes of two groups were analyzed by two-dimensional gel electrophoresis(2-DE).Results Compared with the model group,obvious changes were found in 7 kinds of differentially expressed proteins in rats testes of the treatment group,of which 4 kinds were up-regulated and 3 down-regulated.After digestion and identification by the matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrum,5 kinds from the 7 kinds of proteins were identified as phosphatidyl ethanolamine-binding protein(PEBP),heat shock 70 kDa protein 8,triose-phosphate isomerase,glyceraldehyde-3-phosphate dehydrogenase(GAPDH),and glutathione S-transferase Mu 1(GSTM1-1).Conclusion The anti-aging mechanism of therapy of tonifying kidney and replenishing essence is probably related with the regulation of testis protein expression in aged rats.
