Omentin-1 protects against endothelial dysfunction through the AMPK/KLF2/eNOS pathway in adult rat offspring exposed to maternal diabetes.

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
objectiveExposure to gestational diabetes mellitus appears to produce several effects on offspring, including increased rates of early-onset cardiovascular disease from childhood to early adulthood. In this study, we investigated the protection of human omentin-1 against endothelial dysfunction resulting from exposure to maternal diabetes in adult rat offspring.
methodsTwelve adult control mother offspring (CMO) were injected with rh-omentin or saline, and 12 adult diabetic mother offspring (DMO) were injected with rh-omentin or saline. The mesenteric artery rings of rh-omentin-injected DMO were incubated with Compound C (an AMPK inhibitor). The vascular reactivity of rat mesenteric artery rings was evaluated by treating with PE (10
resultsInjection of rh-omentin alleviated PE-induced vasoconstriction and improved Ach-induced vasorelaxation in the mesenteric artery rings, inhibited phosphorylations of endoplasmic reticulum (ER) stress markers, prevented loss of phosphorylations of AMPK and endothelial nitric-oxide synthase (eNOS), increased nitric oxide production, reduced the level of reactive oxygen species, and promoted KLF2 expression in DMO. The AMPK inhibitor and KLF2 knockdown both eliminated these effects of omentin-1 on adult rat offspring exposed to maternal diabetes. KLF2 knockdown also weakened the effects of the AMPK agonist on adult rat offspring exposed to maternal diabetes.
conclusionThese findings point out that mentin-1 could protect adult rat offspring against endothelial dysfunction, including endothelium impairment, ER stress, and oxidative stress resulting from exposure to maternal diabetes through the AMPK/KLF2/eNOS pathway.
