1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Hypercholesterolemia characterized by elevation of low-density lipoprotein (LDL) cholesterol is a major risk factor for atherosclerotic vascular disease. p66shc mediates hypercholesterolemia-induced endothelial dysfunction and atheromatous plaque formation. We asked if LDL upregulates endothelial p66shc via changes in the epigenome and examined the role of p66shc in LDL-stimulated endothelial cell dysfunction. Human LDL stimulates human p66shc promoter activity and p66shc expression in human endothelial cells. LDL leads to hypomethylation of two CpG dinucleotides and acetylation of histone 3 in the human p66shc promoter. These two CpG dinucleotides mediate LDL-stimulated p66shc promoter activity. Inhibition or knock down of DNA methyltransferases negates LDL-induced endothelial p66shc expression. p66shc mediates LDL-stimulated increase in expression of endothelial intercellular adhesion molecule-1 (ICAM1) and decrease in expression of thrombomodulin (TM). Mirroring these changes in ICAM1 and TM expression, p66shc mediates LDL-stimulated adhesion of monocytes to endothelial cells and plasma coagulation on endothelial cells. These findings indicate that LDL cholesterol upregulates human endothelial p66shc expression via hypomethylation of CpG dinucleotides in the p66shc promoter. Moreover, they show that LDL-stimulated p66shc expression mediates a dysfunctional endothelial cell surface, with proadhesive and procoagulant features.
