title: Proteomic study of serum proteins in a type 2 diabetes mellitus rat model by Chinese traditional medicine Tianqi Jiangtang Capsule administration.
abstract: Proteomics technology was for the first time applied to investigate the changes of serum proteins levels in type 2 diabetes mellitus (T2DM) rat model after treated by Chinese traditional medicine Tianqi Jiangtang Capsule (ten normal Wistar rats, ten with T2DM and ten with T2DM administrated by Tianqi Jiangtang Capsule). In addition to two-dimensional polyacrylamide gel electrophoresis (2-DE), serum protein profiling in the three groups was further performed using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-TOF-TOF/MS). 11 visualized spots were differentially regulated and identified as diabetes-associated proteins. All the samples in three groups were then analyzed by ELISA and estimated the 7 proteins which were found to vary. The distinct effect of T2DM induction on the pattern of rat serum includes the down-regulation of Apolipoprotein E, Apolipoprotein A-I, Ig gamma-2A chain C region, and up-regulation of Transthyretin (TTR), Haptoglobin (Hp), Serum amyloid P-componen (SAP), Prothrombin. The majority of those protein levels were interestingly restored to those of healthy rats after Tianqi Jiangtang Capsule treatment.
