1 Muscle-derived expression of the chemokine CXCL1 attenuates diet-induced obesity and improves fatty acid oxidation in the muscle. Fatty Acids chemokine (C-X-C motif) ligand 1 Mus musculus
2 Furthermore, in CXCL1-transfected muscles, muscular ex vivo fatty acid oxidation was significantly enhanced compared with control muscles (chow fed: 2.2-fold, P < 0.05; high-fat fed: 2-fold, P < 0.05) and also showed increased expression levels of major fatty acid oxidation genes (CD36, CPT I, and HADH). Fatty Acids chemokine (C-X-C motif) ligand 1 Mus musculus

4 In conclusion, our data show that overexpression of CXCL1 within a physiological range attenuates diet-induced obesity, likely mediated through a CXCL1-induced improvement of fatty acid oxidation and oxidative capacity in skeletal muscle tissue.
