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

backgroundThe evolutionary conservation of lipid storage mechanisms across metazoans is well illustrated by vertebrate white adipose tissue (WAT) and its functional counterpart, the amphibian fat body. While serving as the principal lipid reservoir, the amphibian fat body is connected to the gonads and demonstrates unique endocrine-reproductive integration, particularly through its bidirectional regulation of gonadal function and energy metabolism. However, our understanding of this organ's cellular heterogeneity and sex-specific functional adaptations is still limited.

resultsIn this study, we investigated the molecular mechanisms underlying the adipose tissue specialization in Bufo gargarizans, revealing sex- and depot-specific adaptations between visceral fat bodies and subcutaneous adipose tissue. Through comparative transcriptomics, we identified 1,201 visceral and 1,225 subcutaneous sex-biased differentially expressed genes (DEGs), with functional enrichment in calcium signaling pathway, MAPK signaling pathway, and vascular smooth muscle contraction. Subcutaneous depots exhibited calcium flux-driven lipogenesis regulation, where CACNA1G and NCX1 orchestrated adipocytes differentiation via PHKG1-mediated phosphorylation and NFATc1 nuclear translocation. In visceral fat bodies, sexually dimorphic metabolic strategies were prominent, females prioritized lipid storage through TCA cycle augmentation, while males upregulated Mucin-type O-glycan biosynthesis, suggesting a protective role against testicular oxidative stress. Regulatory divergence in subcutaneous adipose tissue extended to vascular dynamics, males enhanced KLF2-dependent angiogenesis via the Apelin pathway, whereas females activated MYLK3-mediated vascular permeability through tight junction remodeling.

conclusionsOur study revealed the central role of calcium signaling in adipose tissue diversification in B. gargarizans, linking tissue-biased gene networks to evolutionary adaptations. We found subcutaneous fat depots prioritized calcium-mediated adipogenesis, while visceral fat diverged into female lipid storage versus male gonadal protection via Mucin O-glycans. Our work redefines amphibian adipose systems as vertebrate lipid metabolism models, uncovers evolutionarily conserved modules in vascular regulation and stress-induced glycosylation, and elucidates mechanisms bridging adaptive energy allocation in amphibians.
