| 233080 | Q3UFD7 | FFAR3_MOUSE | Free fatty acid receptor 3 (G-protein coupled receptor 41) | DISRUPTION PHENOTYPE | Knockout mice display a retarded growth of sympathetic innervation and the superior cervical ganglion is significantly smaller. A heart rate decrease is also observed together with altered secretion of cardiac noradrenaline that might be due to reduced sympathetic nerve activity. Contrary to wild-type mice, oxygen consumption is not modified by feeding or starvation (PubMed:21518883). They also display impaired SCFA-triggered glucagon-like peptide 1/GLP-1 secretion and impaired glucose tolerance (PubMed:22190648). Finally, knockout mice display altered protective intestinal inflammatory and immune responses. Otherwise, they display normal growth and no major morphological abnormalities. Body weight, heart weight to body weight ratio, and metabolic parameters are comparable. However, there might be a gender bias, the effect on energy expenditure and body fat content being male specific (PubMed:23110765). {ECO:0000269|PubMed:18931303, ECO:0000269|PubMed:21518883, ECO:0000269|PubMed:22190648, ECO:0000269|PubMed:23110765, ECO:0000269|PubMed:23665276}. |
