Moreover, SPH inhibited the DEX-induced increase in cytosolic p-Akt protein expression and suppressed the increase in nuclear FoxO3a protein expression, thereby suppressing the increase in the protein expression of the ubiquitin-proteasome-related factors Atrogin-1 and MuRF-1, which are involved in muscle atrophy. This evidence concerns the gene AKT1 and Atrophy.
