Protein synthesis and degradation signaling in skeletal muscle after muscle disuse atrophy: modulation by omega-3 fatty acids

We investigated herein: 1) the effects skeletal muscle disuse atrophy induced by two-week hind limb suspension (HS) on protein synthesis and degradation signaling in soleus muscle and the administration of either eicosapentaenoic (EPA) or docosahexaenoic (DHA)-rich fish oil supplementation, and 2) t...

Sumario:We investigated herein: 1) the effects skeletal muscle disuse atrophy induced by two-week hind limb suspension (HS) on protein synthesis and degradation signaling in soleus muscle and the administration of either eicosapentaenoic (EPA) or docosahexaenoic (DHA)-rich fish oil supplementation, and 2) the changes induced by hind limb disuse on soleus muscle of Fat-1 transgenic mice. We concluded that, in spite of the small variation in the omega-6/omega-3 fatty acid ratio, significant effects of the increased omega-3 fatty acid levels were observed on the CSA and signaling pathways associated with soleus muscle protein synthesis and degradation in both experimental protocols.
