We have examined the possibility of concurrently reducing LDL levels and modulating endothelial function using a single helper-dependent adenovirus vector system to simultaneously express the apolipoprotein B mRNA editing enzyme (Apobec1) and the scavenger receptor, class B, type I (SR-BI) genes under the control of separate promoters (designated HD-C2). Apobec1 edits apoB mRNA at nucleotide C-6666 to produce truncated apoB48 and is normally expressed in small intestine only. SR-BI is a receptor for multiple ligands with distinct tissue-specific functions. Expression of Apobec1 in HepG2 cells resulted in apoB mRNA editing, leading to decreased apoB100 abundance (to 6% of control) and the appearance of apoB48. Editing of apoB mRNA in HepG2 cells resulted in decline in apoB mRNA levels of 50%. This was probably the result of nonsense-mediated decay of edited message, since over-expression of Apobec1 increased neither Apobec1 complementary factor (ACF) mRNA nor protein abundance. Over-expression of SR-BI in human endothelial cells activated endothelial nitric oxide synthase (eNOS) activity by phosphorylation of eNOS at residue Ser-1177 in the presence of HDL, leading to increased production of the anti-atherogenic molecule nitric oxide (NO). Taken together, this study demonstrates that using one vector delivery system to express two genes in two different cell types results in the cell-specific beneficial effects of decreasing apoB100 production and increasing eNOS activities. This combined gene expression approach may provide an improved therapeutic strategy by targeting multiple sites in the mechanism of cardiovascular injury."xsd:string |
