Gene Dynamics in Maternal Nutrition: The Role of Chromium in Mitigating Offspring Obesity.
Article in Biological trace element research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study investigates the potential mechanisms by which maternal chromium (Cr) supplementation mitigates offspring obesity through identification of key regulatory genes. Sixteen pregnant C57BL/6 mice were randomly allocated to either control (CON) or chromium-supplemented (CR) dietary groups, with nutritional interventions administered throughout gestation and lactation. Post-weaning, all offspring received CR diets until 32 weeks of age. Comparative analysis revealed significant reductions in adipose tissue mass and 136 differentially expressed genes (DEGs) in CR offspring adipose tissue, identified through GEO2R analysis. Functional enrichment analyses revealed significant involvement of these DEGs in critical metabolic pathways: lipid metabolism regulation (PPAR signaling), steroid hormone biosynthesis, cholesterol homeostasis, and fatty acid oxidation processes. Protein-protein interaction network analysis identified 14 hub genes central to adipocyte regulation, including ACSL1, DGAT1, ADIPOQ, PPARD, PPARG, SREBF1, APOC2, and FABP1, which collectively demonstrate synergistic effects in suppressing lipid accumulation. These findings elucidate molecular mechanisms underlying chromium-mediated protection against metabolic disorders and propose novel therapeutic targets for intergenerational obesity prevention. The identified gene network provides a framework for developing maternal nutritional strategies and pharmacological interventions targeting epigenetic regulation of lipid metabolism.
