RESUMEN
OBJECTIVE: To study the modulation of Jianjining Recipe (JJNR), a traditional Chinese compound herbal medicine for invigorating spleen and kidney on differential protein expression in spleen of rats with experimental autoimmune myasthenia gravis (EAMG). METHODS: EAMG rats were randomly divided into four groups: untreated group, JJNR-treated group, Qiangji Jianli capsule (QJJLC, a traditional Chinese compound herbal medicine)-treated group and prednisolone acetate (PA)-treated group. After therapeutic intervention with the above drugs for four consecutive weeks, the level of differential protein expression was analyzed by two-dimensional electrophoresis and matrix assisted laser desorption/ionization time-of-flight mass spectrometry. RESULTS: Twelve differential proteins were identified by comparing EAMG rats and normal rats. The levels of allograft inflammatory factor-1, peroxiredoxin I and actin-related protein 2/3 complex subunit 5 were significantly regulated by JJNR (P<0.01). These proteins were closely associated with immune response and cell movement. CONCLUSION: The results suggest that there are differential protein expressions between EAMG rats and normal rats. Furthermore, as a Chinese medicine prescription with effect of invigorating spleen and kidney, JJNR can effectively regulate the levels of some EAMG-related protein expression.
