Effect of resveratrol derivative BTM-0512 on high glucose-induced dysfunction of endothelial cells: role of SIRT1
Bibliographic record
Abstract
Hyperglycemia impairs the function of endothelial cells. Sirtuin 1 (SIRT1) is involved in regulating the function of endothelial cells. Resveratrol, a polyphenol found in many plant species, exerts protective effects on endothelial cells through activation of SIRT1. The aims of this work were to explore whether BTM-0512, a novel derivative of resveratrol, is able to exert beneficial effects on high glucose-induced dysfunction of endothelial cells through regulation of SIRT1. We found that high glucose significantly impaired the function of endothelial cells as shown by reduced tube formation, cell migration, and cell adhesion concomitantly with downregulation of mRNA expression of SIRT1 and vascular endothelial growth factor as well as increased tumor necrosis factor-α release and reactive oxygen species production. These effects of high glucose were inhibited by pretreatment with BTM-0512. The beneficial effects of BTM-0512 on high glucose-induced cell dysfunction were abolished by splitomicin, a specific inhibitor of SIRT1. The regulatory effects of BTM-0512 on high glucose-induced changes in vascular endothelial growth factor mRNA expression and tumor necrosis factor-α release were also abolished by splitomicin. The results suggest that BTM-0512 exerts beneficial effects on high glucose-induced endothelial cell dysfunction through regulation of the SIRT1 - reactive oxygen species - vascular endothelial growth factor - tumor necrosis factor-α pathway.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
