- Abstract
To construct a recombinant adenovirus vector expressing a RNAi for the Nuclear Factor kappa B (NF-κB)/p65 gene and use it to explore the role of the NF-κB pathway on the regulation of proliferation and apoptosis of vascular endothelial cells. A recombinant adenovirus containing a RNAi cassette targeting the p65 gene was constructed, and its silencing effect on p65 was detected by Western blot analysis in ECV304 cells. Expression of the p65 protein in ECV304 cells was efficiently down-regulated by the RNAi adenovirus for more than 6 days. ECV304 cells proliferation and apoptosis were measured using the MTT assay and flow cytometry, respectively. Blocking the NF-κB pathway with the RNAi adenovirus substantially decreased the proliferation of ECV304 cells, but only slightly affected cell apoptosis. We used a NF-κB/p65-targeting RNAi adenovirus to demonstrate the role of the NF-κB pathway in the regulation of ECV304 cell proliferation. This adenovirus may serve as an important tool to study the NF-κB pathway.
