Hypothesis
Lonafarnib could reverse dexamethasone-induced muscle atrophy and restore muscle health to near-normal levels.
Conclusion
Lonafarnib mitigates dexamethasone-induced muscle atrophy by enhancing mitochondrial function and activating anabolic pathways.
Supporting Evidence
- Lonafarnib significantly improved myotube area, fusion index, and diameter in C2C12 myotubes.
- In C. elegans, lonafarnib increased the pharyngeal pumping rate, indicating enhanced neuromuscular function.
- In DEX-induced atrophic rats, lonafarnib improved maximal grip strength and increased muscle weight.
Takeaway
Lonafarnib is a medicine that helps muscles stay strong and healthy, especially when they are getting weak from a medicine called dexamethasone.
Methodology
The study used in vitro models with C2C12 myotubes and in vivo models with Caenorhabditis elegans and DEX-treated Sprague–Dawley rats to assess the effects of lonafarnib on muscle atrophy.
Limitations
The use of dexamethasone-induced models may not fully replicate the complexities of natural aging or the multifactorial aetiology of sarcopenia.
