Abstract:

Skeletal muscle wasting is a consequence of the decrease of muscle protein synthesis and/or degradation acceleration,and often accompanies with various serious diseases,such as pathogen infection,injury and tumor.At present,many studies have shown that the systemic inflammation is playing an important role in the process of muscle wasting.Based on the current literature,we present an overview of the molecular and cellular mechanisms that contribute to the inflammation-induced muscle wasting,mainly including the ubiquitin-proteasome pathway (UPP),autophagy-lysosomal pathway (ALP),PI3K/Akt pathway,p38/MAPK pathway and NF-κB pathway,which hope to offer the guidance for the treatment of skeletal muscle wasting.

Key words: skeletal muscle wasting; protein degradation; inflammation
