The study aims to determine the influence of plasma lipoproteins on prostacyclin biosynthesis in vascular endothelial cells.
Human HDL and LDL were incubated with porcine arterial endothelial cells in tissue culture.
Prostacyclin production was measured using radioimmunoassay of its stable metabolite, 6-keto-PGF1 alpha.
Time course experiments tracked 6-keto-PGF1 alpha levels over 24 hours.
HDL significantly increased 6-keto-PGF1 alpha levels 5-fold above control, in a dose-dependent manner (p<0.001).
No significant increase in 6-keto-PGF1 alpha was observed with LDL.
Rat HDL released 2-4-fold more 6-keto-PGF1 alpha than human HDL, attributed to higher arachidonate content.
