[Effects of Siwu tang on serum protein of blood deficiency using proteomic technique].

OBJECTIVE: To research the effects of Siwu tang on serum protein of blood deficiency using proteomic technique and further explore its potential molecular mechanism to cure blood deficiency.

METHOD: The sera of normal, blood deficiency and cured group were collected. Proteomic protocol involving the high resolution two-dimensional polyacryamide gel electrophoresis, the computer-assisted image analysis, and the mass spectrometry was used to detect regulated protein by Siwu tang.

RESULT: Compared with normal group, there were 15 proteins changed, in which 11 increased and 4 decreased expressed proteins in sera could be recovered by Siwu tang. The up-regulated proteins involved haptoglobin, clusterin, complement component C4B and GTP binding protein 2, while the down-regulated proteins involved transthyretin and heamoglobin beta.

CONCLUSION: Siwu tang could regulate serum protein, which include immunology, apoptosis, DNA injury repair, and blood ingredients. This might be the mechanism of Siwu tang to cure blood deficiency.
