1 · What the graph read from it

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.

2 · The registry

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

objectiveThis study investigates the correlations between obesity-related plasma markers and epigenetic/inflammatory changes in white adipose tissue (WAT), focusing on adipose-derived stem cells (ASCs). We hypothesize that obesity modulates histone H3K27 marks, modified by demethylases (lysine-specific demethylase 6A and 6B [KDM6A/KDM6B]) and acetylases (CREB-binding protein [CREBBP]/histone acetyltransferase EP300), affecting ASC function.

methodsSerum and visceral WAT (omental region) was collected from male patients (n = 16, 30-50 years old) undergoing elective gastric or bariatric surgery. BMI and obesity markers were correlated with changes in ASCs (transcript expression, proliferation, and secretion) using reverse transcriptase-polymerase chain reaction.

resultsASCs from individuals with higher BMI exhibited slower proliferation, increased inflammatory profile, and reduced adipogenic potential, with lower expression of key adipogenic genes. H3K27 acetylase transcripts were also negatively correlated with adipogenesis regulators. Moreover, C-C motif chemokine 2 (CCL2) and KDM6A expression was higher in the group with obesity, as were CREBBP and EP300. Finally, leptin levels positively correlated with serum, WAT, and ASC CCL2 expression. In vitro, leptin exposure enhanced CCL2 expression/secretion and increased KDM6A/KDM6B and EP300 transcription.

conclusionsIn vitro leptin exposure enhanced CCL2 expression/secretion and increased KDM6A/KDM6B and EP300 transcription, highlighting how obesity-driven epigenetic mechanisms, including leptin-mediated pathways, disrupt ASC plasticity and perpetuate adipose tissue dysfunction, offering novel therapeutic targets for metabolic disease intervention.
