Extract of Housefly (Musca Domestica) Maggot Anti-inflammatory Parts Could Regulate the Proliferation and Migration of TNF-α- stimulated Human Umbilical Vein Endothelial Cells

摘要

House fly maggot, Musca domestica (Linnaeus) (Diptera: Muscidae) is one of the traditional Chinese medicine (TCM). In our earlier studies, the anti-inflammatory and anti-atherosclerotic functions of the housefly maggot have been found and also the anti-inflammatory effective parts have been acquired. In this study, the effect of housefly maggot anti-inflammatory parts on proliferation and migration of TNF-α-stimulated human umbilical vein endothelial cells (HUVEC) were investigated. And the results showed that the proliferation index and the migration rates of HUVEC which stimulated by TNF-α were decreased significantly in housefly maggot antiinflammatory parts treatment group. And also the secretion of vascular endothelial growth factor (VEGF) was decreased too compared with only TNF-α treatment group. Based on the above, the housefly maggot anti-inflammatory parts could regulate the endothelial cell dysfunction through decreasing cell proliferation and migration and a reduction in VEGF expression might plays a key role in this process.
