Coenzyme Q10 Supplementation Modulates Hepatic Lipidomic Alterations and Attenuates Metabolic Dysfunction-Associated Steatohepatitis in Mice.
Article in Nutrients, 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
BACKGROUND/
objectivesMetabolic dysfunction-associated steatohepatitis (MASH) is a chronic liver disorder with limited effective therapeutic options. Emerging lipidomic studies suggest that alterations in membrane-associated lipids contribute to MASH pathophysiology; however, nutritional interventions capable of modifying these lipid alterations remain poorly defined. This study aimed to investigate the effects of coenzyme Q10 (CoQ) supplementation on hepatic lipidomic remodeling in a methionine- and choline-deficient (MCD) diet-induced mouse model of MASH.
methodsMale C57BL/6J mice were fed a methionine- and choline-sufficient diet or an MCD diet for 4 weeks, with MCD-fed mice receiving vehicle or CoQ (100 mg/kg body weight/day). Hepatic lipid profiles were assessed using untargeted LC-MS-based lipidomics, and expression of genes involved in phospholipid and sphingolipid metabolism was quantified by quantitative real-time PCR.
resultsCoQ supplementation significantly attenuated liver injury induced by the MCD diet, as evidenced by reduced histological severity and decreased serum ALT and AST levels. Lipidomic analyses revealed marked alterations in hepatic phospholipid and sphingolipid profiles during MASH development. CoQ was associated with remodeling of phospholipid composition, increasing phosphatidylcholine (PC) species and reducing phosphatidylethanolamine (PE) species, resulting in an increased hepatic PC to PE ratio. This change was accompanied by upregulation of
conclusionsCoQ supplementation was associated with attenuation of MCD diet-induced MASH and modulation of hepatic phospholipid homeostasis, supporting its potential as a nutritional intervention targeting membrane lipid dysregulation in MASH.
