Abstract:
Objective To study the influence of Annao tablet on the expression of transforming growth factor beta 1 (TGF-β1) in acute graft-versus-host disease (aGVHD) murine and to explore the interventional mechanism of TGF-β1 on aGVHD. Methods Hematopoietic stem cells of male Balb/c mice were transplanted to female C57BL/6 mice for the development of aGVHD murine model. Recipient mice were divided into Annao group and blank group randomly and respectively administrated with Annao soup (a kind of Chinese herb) and 0.9% sodium chloride intragastrically. Clinical symptom, survival time and body weight were recorded at 14th and 30th day and some sections of liver, small bowel and skin were taken for histological changes. Serum level of TGF-β1 were measured by enzyme-labeled immunosorbent assay (ELISA), splenocyte protein of TGF-β1 by Western Blot and TGF-β1 mRNA by fluorescent quantitation polymerase chain reaction (PCR). Results Serum level of TGF-β1 in both groups had no statistical difference (P = 0.305), but it rose to (148.31 ± 7.95) ng/mL at 14th day and (183.48 ± 5.91) ng/mL at 30th day in Annao group, which had significant difference when compared with that in blank group (P = 0.000). IOD/IODβ-actin value of TGF-β1 protein in Annao group was 0.33 ± 0.05 at 14th day and 0.56 ± 0.04 at 30th day, which was higher than that in blank group (P = 0.000) and the expression of TGF-β1 mRNA of splenocyte in Annao group was 1.24 ± 0.04 at 14th day and 2.14 ± 0.33 at 30th day which was much higher than that in blank group (P = 0.000). Conclusion Annao tablet helps to relieve symptoms of acute GVHD by raising serum level of TGF-β1 and intensifying expression of protein of TGF-β1 and its mRNA.
