Lonafarnib Protects Against Muscle Atrophy Induced by Dexamethasone.
Article in Journal of cachexia, sarcopenia and muscle, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundMuscle atrophy, including glucocorticoid-induced muscle wasting from treatments such as dexamethasone (DEX), results in significant reductions in muscle mass, strength and function. This study investigates the potential of lonafarnib, a farnesyltransferase inhibitor, to counteract DEX-induced muscle atrophy by targeting key signalling pathways.
methodsWe utilized in vitro models with C2C12 myotubes treated with DEX and in vivo models with Caenorhabditis elegans and DEX-treated Sprague-Dawley rats. Myotube morphology was assessed by measuring area, fusion index and diameter. Muscle function was evaluated by grip strength and compound muscle action potential (CMAP) in the gastrocnemius (GC) and tibialis anterior (TA) muscles. Molecular mechanisms were explored through RNA sequencing and Western blotting to assess changes in mitochondrial function and muscle signalling pathways.
resultsLonafarnib (2 μM) significantly improved myotube area (1.49 ± 0.14 × 10
conclusionsLonafarnib mitigates dexamethasone-induced muscle atrophy by enhancing mitochondrial function and activating anabolic pathways. These findings support further investigation of lonafarnib as a therapeutic agent for muscle atrophy in clinical settings.
