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

Circadian rhythms align biological functions with the 24-hour day-night cycle, but modern artificial light disrupts these patterns, contributing to health issues like obesity and cardiovascular disease. The circadian clock operates through a transcriptional-translational feedback loop involving core components such as BMAL1 and CLOCK. Recent research has shown circadian variations in sphingolipid metabolism, specifically sphingosine-1-phosphate (S1P), which plays crucial signaling roles. This study investigates the sphingolipid enzyme, sphingosine kinase 1 (SphK1), which converts sphingosine to S1P, as a circadian-regulated gene in adipocytes. We find that SphK1 expression and activity follow a circadian rhythm, regulated by BMAL1 and CLOCK binding to its promoter. Adipocyte-specific SphK1 knockout mice exhibit disrupted circadian rhythms, and impaired adipocyte function. Additionally, SphK1 deficiency leads to reduced histone acetylation and altered histone deacetylase (HDAC) localization, affecting gene regulation. These results highlight the critical role of SphK1 in linking lipid metabolism with circadian biology.
