ABSTRACT

Objective:

To investigate the effect of modified Si Junzitang on angiogenesis in transplanted tumor of H22 tumor-bearing mice.

Method:

The effect of modified Si Junzitang on tumor inhibition and growth of peripheral blood vessels in tumor-bearing mice was observed by tumorigenesis experiment in mice. Hematoxylin-eosin (HE) staining and immunohistochemistry (IHC) were used to detect the distribution of blood vessels and the expression of vascular endothelial markers (CD31) in tumor-bearing mice. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the mRNA expression levels of vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor 2 (VEGFR2) and tumor necrosis factor-α (TNF-α) in tumor tissue.

Result:

The inhibition rates of modified Sijunzi Tang in low-dose group (ig, 11.83 mg·kg-1·d-1), middle-dose group (ig, 23.66 mg·kg-1·d-1) and high-dose group (ig, 47.32 mg·kg-1·d-1) were 29.97%, 59.80%and 82.34%, respectively. Compared with the model group, the average tumor weight was lower in middle and high-dose groups, with statistically significant differences (PPPα in middle and high-dose modified Si Junzitang groups were lower than those in the model group (P

Conclusion:

Modified Si Junzitang can inhibit the tumor growth of H22 tumor-bearing mice and the angiogenesis of transplanted tumors, which may be related to the reduction of TNF-α, VEGF and VEGFR2 expression levels.
