The primary aim of this study was to investigate the effects and mechanisms of EPA and DHA on myogenic IL-6 and lipid metabolism disorders in mice, and to clarify the association between the alleviation of lipid metabolism disorders and myogenic IL-6 mediated by EPA/DHA. We found that EPA and DHA not only prevented high-fat diet-induced lipid metabolism disorders, but also up-regulated the expression of myogenic IL-6 by activating TRPV1/Ca<sup>2+</sup> signaling in skeletal muscle. However, the lipid metabolism prevention effect mediated by EPA was weakened after knockout gene of myogenic IL-6, with its body weight and body fat increased and a large amounts of lipid deposited in the blood, liver, and adipocytes.
