Abstract: Resolution of inflammation is now known to be an active process which in part is instigated and controlled by specialised pro-resolving lipid mediators (SPM’s) derived from dietary omega-3 fatty acids. Resolvin E1 (RvE1) is one of these SPM’s derived from the omega-3 fatty acid eicosapentaenoic acid. Using both molecular and phenotypic functional measures we report that in a model of Lipopolysaccharide (LPS) induced inflammation, RvE1 attenuated mRNA gene expression levels of both interlukin-6 and monocyte chemoattractant protein-1 whilst having no effect on tumour necrosis factor-α or Interlukin-1β in C2C12 skeletal muscle myotubes. Findings at the molecular level were transferred into similar changes in extracellular protein levels of the corresponding genes with the greatest attenuation being noted in IL-6 protein concentrations. RvE1 instigated beneficial morphological changes through the prevention of endotoxin induced skeletal muscle atrophy, thus resulting in a rescue of endotoxin force losses in tissue engineered skeletal muscle. These findings demonstrate, in our model of endotoxin induced inflammation in skeletal muscle, that RvE1 has pro-resolving properties in this cell type. Our data provides rationale for further investigation into the mechanistic action of RvE1 in skeletal muscle, with the vision of having potential benefits for the prevention/resolution of in vivo skeletal muscle atrophy.
