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

backgroundCeramides have garnered considerable attention as pro-aging bioactive lipids implicated in both metabolic dysfunction and musculoskeletal decline. Among these, C18:0 and C24:1 ceramides may play a role in the pathophysiology of sarcopenia, a key manifestation of age-related deterioration. However, their specific contributions to muscle degeneration remain poorly defined.

methodsC2C12 myoblasts and primary myoblasts were treated with C18:0 or C24:1 ceramides during differentiation to assess myotube formation, migration and intracellular reactive oxygen species (ROS) levels. Three-month-old C57BL/6 mice received daily intraperitoneal injections of C18:0 or C24:1 ceramides for 4 weeks to evaluate muscle morphology and function. In a human cohort of 165 community-dwelling older adults (≥ 65 years), serum ceramide levels were measured via LC-MS/MS and analysed in relation to sarcopenia parameters.

resultsBoth C18:0 and C24:1 ceramides significantly impaired myogenic differentiation in vitro, as evidenced by reduced myotube number, total myotube area, average area per myotube, nuclei count per myotube and fusion index, through ROS-mediated mechanisms (with up to an 8.6-fold increase in ROS production). Consistently, C18:0 and C24:1 ceramides markedly downregulated key myogenic markers and inhibited ITGB1-FAK-AKT signalling while promoting nuclear activation of FoxO-associated catabolic pathways. These deleterious effects were attenuated by treatment with the antioxidant N-acetylcysteine. In mice, systemic administration of either ceramide resulted in reduced muscle fibre cross-sectional area in the tibialis anterior (by 20.5% and 20.9% for C18:0 and C24:1, respectively) and soleus muscles (by 18.1% and 16.1%), accompanied by decreased grip strength, shorter grid hanging times and reduced latency to fall in the rotarod test. Clinically, in a cohort of 165 older adults (80.6% female; mean age 75.2 ± 5.2 years in controls and 79.7 ± 4.8 years in the sarcopenia group), serum levels of C18:0 and C24:1 ceramides were 27% and 14% higher, respectively, in individuals with sarcopenia compared to controls (p = 0.001 and 0.018). Furthermore, each standard deviation increase in serum C18:0 and C24:1 ceramide levels was associated with a 2.0- and 1.6-fold increased risk of sarcopenia, respectively (p = 0.003 and 0.040).

conclusionsOur findings reveal that circulating C18:0 and C24:1 ceramides are significantly associated with sarcopenia in older adults, while experimental models demonstrate they promote muscle atrophy through oxidative stress-induced impairment of myogenesis and muscle function. These ceramides may serve as minimally invasive biomarkers and potential therapeutic targets for age-related muscle decline. Interventions aimed at modulating ceramide metabolism could offer new avenues for sarcopenia prevention and treatment in aging populations.
