Abstract

Summary: Introduction: Hyperglycemia‐induced oxidative stress has been implicated in diabetic vascular complications in which NADPH oxidase is a major source of reactive oxygen species ( ROS ) generation. Resveratrol is a naturally occurring polyphenol, which has vasoprotective effects in diabetic animal models and inhibits high glucose ( HG )–induced oxidative stress in endothelial cells. Aims: We aimed to examine whether HG ‐induced NADPH oxidase activation and ROS production contribute to glucotoxicity to endothelial cells and the effect of resveratrol on glucotoxicity. Results: Using a murine brain microvascular endothelial cell line bE nd3, we found that NADPH oxidase inhibitor (apocynin) and resveratrol both inhibited HG ‐induced endothelial cell apoptosis. HG ‐induced elevation of NADPH oxidase activity and production of ROS were inhibited by apocynin, suggesting that HG induces endothelial cell apoptosis through NADPH oxidase–mediated ROS production. Mechanistic studies revealed that HG upregulated NADPH oxidase subunit N ox1 but not N ox2, N ox4, and p22 phox expression through NF ‐κB activation, which resulted in elevation of NADPH oxidase activity and consequent ROS production. Resveratrol prevented HG ‐induced endothelial cell apoptosis through inhibiting HG ‐induced NF ‐κB activation, NADPH oxidase activity elevation, and ROS production. Conclusions: HG induces endothelial cell apoptosis through NF ‐κB/ NADPH oxidase/ ROS pathway, which was inhibited by resveratrol. Our findings provide new potential therapeutic targets against brain vascular complications of diabetes.

  • Studies have shown links between high NOX1 levels and hypertension, diabetes, ischemia/reperfusion injury, and coronary artery disease.

    “Increased NOX1 activity is associated with vascular disease, and studies have shown links between high NOX1 levels and hypertension (1015), diabetes (163, 380, 1003), ischemia/reperfusion injury (479), and coronary artery disease (393).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
