[Gly14]-Humanin ameliorates high glucose-induced endothelial senescence via SIRT6.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
High glucose (HG) induced endothelial senescence is related to endothelial dysfunction and cardiovascular complications in diabetic patients. Humanin, a member of mitochondrial derived peptides (MDPs), is thought to contribute to aging-related cardiovascular protection. The goal of the study is to explore the pathogenesis of HG-induced endothelial senescence and potential anti-senescent effects of Humanin. Human umbilical vein endothelial cells (HUVECs) were exposed to glucose to induce senescence, determined by β-galactosidase staining and the expressions of p21, p53, and p16. A clinically relevant dose of HG (15 mM, HG) induced endothelial senescence after 72 h incubation without elevated apoptosis. HG-induced senescence was attributed to the induction of reactive oxygen species (ROS) caused by SIRT6 downregulation, as ROS inhibitor N-acetyl cysteine blocked HG-induced senescence, while inactivation of SIRT6 increased ROS levels and promoted senescence. Strikingly. pretreatment with [Gly14]-Humanin (HNG) antagonized the downregulation of SIRT6 in response to HG and alleviated ROS production and cell senescence. HG-induced reduction of SIRT6 results in ROS overproduction and endothelial senescence. Humanin protects against HG-induced endothelial senescence via SIRT6. This study provides new directions for biological products related to Humanin to be a potential candidate for the prevention of vascular aging in diabetes.
