Furthermore, MS-275 restored Akt and ARK5 phosphorylation and promoted FoxO1/3 phosphorylation, resulting in decreased expression of the muscle-specific E3 ubiquitin ligases MuRF1 and atrogin-1.<h4>Conclusion</h4>Our findings demonstrate that epigenetic inhibition of class I HDACs by MS-275 attenuates diabetes-associated skeletal muscle atrophy by coordinately suppressing inflammatory signaling and myostatin-driven catabolic pathways while restoring Akt/ARK5-FoxO signaling. The gene discussed is FBXO32; the disease is diabetes mellitus.
