The Study of Signaling Pathways in MCP-1 Over-Expression/Interference of HUVECs / 天津医药

ABSTRACT

Objective To investigate the association between the signaling pathways of MCP-1-pCDH-GFP-trans?fected cells and deep venous thrombosis (DVT). Methods The cultured human umbilical vein endothelial cells (HUVECs) were tested by immunofluorescence and co-immunoprecipitation methods. The constructed MCP-1 over-expression/interfer?ence vector, and the change of transcription profile were detected by microarray assay and biological information technology analysis. Results MCP-1 over-expression/interference vector MCP-1-pCDH-GFP/MCP-1-LMP shRNAmir1 was con?structed and HUVECs were transfected. According to the microarray analysis we found that there were 18 down-expressed signaling pathways and 7 up-expressed signaling pathways in MCP-1-pCDH-GFP-transfected cells. There were 60 down-expressed signaling pathways and 15 up-expressed signaling pathways in the MCP-1-LMP shRNAmir1 transfected cells. Conclusion Signaling pathways of MCP-1 plays an important role in DVT formation,which may provide us a new way to study molecular mechanism of DVT.
