Anti-obesity effects of Wumeishanzhayin: an integrated lipidomics and transcriptomics study.
Article in Frontiers in pharmacology, 2025. 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
Background: The global prevalence of adult obesity has increased significantly, affecting over 890 million adults worldwide. Wumeishanzhayin (WMSZY), a formulation derived from four medicinal and edible botanical drugs, has shown efficacy in alleviating obesity and lipid metabolism disorders induced by high-fat and high-fructose (HFHF) diets. However, its underlying therapeutic mechanisms remain unclear. Objective: This study aims to investigate the therapeutic effects and mechanisms of WMSZY in ameliorating obesity induced by a HFHF diet. Methods: UPLC-MS/MS was used to characterize the metabolites of WMSZY. The effects of WMSZY on body weight gain, lipid metabolism, and glucose dysfunction were evaluated in a HFHF diet-induced murine model. Targeted lipidomics and transcriptomics analyses were performed to identify differentially altered lipids (DALs) and differentially expressed genes (DEGs). Computational approaches, including molecular docking simulation and dynamics simulations, were used to predict bioactive compound-target interactions. Key findings were validated through RT-qPCR and Western blot. Integrated transcriptomic and lipidomic analyses identified potential therapeutic targets. Results: Sixteen metabolites were identified in WMSZY. Animal studies showed that WMSZY reduced body weight gain, improved lipid and glucose metabolism, and alleviated inflammation in HFHF diet-induced mice. Targeted lipidomics indicated that WMSZY's anti-obesity effect may be linked to cholesterol metabolism, adipocyte lipolysis, lipid digestion, insulin resistance, and glycerolipid metabolism. Transcriptomic analysis suggested involvement of AMPK, MAPK, and PPAR signaling pathways. Molecular docking simulation revealed strong binding of WMSZY metabolites with AMPK, and simulations showed that cryptochlorogenic acid had notable binding affinity. The data from Western blot and RT-qPCR showed changes associated with the activation of the AMPK/CPT-1 pathway and the inhibition of lipid metabolism-related genes following WMSZY treatment. Conclusion: WMSZY significantly reduces body weight gain and ameliorates glucose and lipid metabolic disorders in HFHF diet-induced mice. Its anti-obesity effect is likely due to the regulation of lipid metabolism
