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

Adipocytes play essential roles in lipid metabolism and energy homeostasis, with regional differences affecting their functions and disease susceptibility. However, the mechanisms underlying this regional heterogeneity remain unclear. Here we demonstrate that the Bithorax Complex (BX-C) genes, specifically abdominal A (abd-A) and Abdominal B (Abd-B), define regional differences in Drosophila larval adipocytes. Abdominal adipocytes, expressing abd-A and Abd-B exhibit unique characteristics compared to thoracic adipocytes, with active Wnt/Wingless signaling further amplifying these regional differences. Depleting abd-A and Abd-B in adipocytes delays larval-pupal transition, causes pupal lethality, and attenuates the expression of Wnt/Wg target genes, thereby dampening Wnt signaling-induced lipid mobilization. Additionally, Wnt signaling enhances the transcription of abd-A and Abd-B, establishing a feedforward loop that reinforces the interplay between Wnt signaling and BX-C genes. These findings reveal how the cell-autonomous expression of BX-C genes defines adipocyte heterogeneity, a process further modulated by Wnt signaling in Drosophila larvae.
