Abstract

Background Endothelial dysfunction is tightly associated with cardiovascular complications in diabetic patients. This study aims to investigate the effects of mangiferin on the regulation of endothelial homeostasis under endoplasmic reticulum stress (ER stress) conditions. Results High glucose (25 mmol/L) exposure induced ER stress and promoted ROS production in endothelial cells. Mangiferin effectively inhibited ER stress-associated oxidative stress by attenuating IRE1α phosphorylation and reducing ROS production. In response to ER stress, thioredoxin-interacting protein (TXNIP) expression increased, followed by NLRP3 inflammasome activation and increased IL-1β secretion. Mangiferin treatment attenuated the expressions of TXNIP and NLRP3 and reduced IL-1β and IL-6 production, demonstrating its inhibitory effects on TXNIP/NLRP3 inflammasome activation. NLRP3 inflammasome activation is responsible for mitochondrial cell death. Mangiferin restored the loss of the mitochondrial membrane potential (Δψm) and inhibited caspase-3 activity, and thereby protected cells from high glucose-induced apoptosis. Moreover, mangiferin inhibited ET-1 secretion and restored the loss of NO production when cells were exposed to high glucose. Mangiferin enhanced AMPK phosphorylation and AMPK inhibitor compound C diminished its beneficial effects, indicating the potential role of AMPK in its action. Conclusion Our work showed the beneficial effects of mangiferin on the improvement of endothelial hom…

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In endothelial cells cultured with mangiferin at 0.1, 1 and 10 microM, expression of TXNIP, NLRP3, IL-1beta and IL-6, and phosphorylation of AMPK, was attenuated, demonstrating inhibitory effects on TXNIP/NLRP3 inflammasome activation and ameliorative effects on endothelial dysfunction.

    “The expression of thioredoxin-interacting protein (TXNIP), NLR family pyrin domain containing 3 (NLRP3), IL-1β and IL-6, as well as the phosphorylation of AMP-activated protein kinase (AMPK), was attenuated in endothelial cells cultured with mangiferin at concentrations of 0.1, 1 and 10 µM, demonstrating its inhibitory effects on TXNIP/NLRP3 inflammasome activation and it ameliorative effects on”

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.
