Objective. To explore the possible role of miR-499a-3p in the function of primary human umbilical vein endothelial cells (HUVECs) and the expression of ADAM10 in primary HUVEC. Method. miR-499a-3p was first transfected into primary HUVECs via lentivirus vector. The viability, proliferation, and migration of stable transfected primary HUVEC were then determined by flow cytometry, CCK8 assays, scratch tests, and Transwell tests. The transcription of miR-499a-3p and ADAM10 was examined by reverse transcription-polymerase chain reaction (RT-PCR), and the expression of ADAM10 was examined by Western blot (WB). Results. After transfection, miR-499a-3p transcription was significantly increased (P<0.01), compared to the blank and nonspecific control (NC) groups, while both ADAM10 transcription and expression were significantly decreased (P<0.05). In contrast, in the inhibitors group, miR-499a-3p transcription was significantly reduced (P<0.05) whereas both ADAM10 transcription and expression were significantly increased (P<0.05). The viability, proliferation, and migration of primary HUVECs were significantly impaired (P<0.05) by the transfection of miR-499a-3p but enhanced by miR-499a-3p inhibitors (P<0.05). Conclusions. Upregulation of miR-499a-3p transcription will inhibit the expression of ADAM10 in HUVECs; cell migration and proliferation, however, promote apoptosis. And reverse effects were established by downregulation of miR-499a-3p transcription. All these effects may be achieved by regulating the transcription and expression of ADAM10. These results combined suggested that miR-499a-3p may affect the proliferation, migration, and apoptosis of endothelial cells and regulate AS by regulating ADAM10. miR-499a-3p may become a candidate biomarker for the diagnosis of unstable angina pectoris (UA).

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 anti-inflammatory 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.
