creation of a DECR-deficient mouse line, fasted Decr-/- mice display increased serum acylcarnitines, especially decadienoylcarnitine, a product of the incomplete oxidation of linoleic acid (C18:2), urinary excretion of unsaturated dicarboxylic acids, and hepatic steatosis, wherein unsaturated fatty acids accumulate in liver triacylglycerols, metabolically challenged Decr-/- mice turn on ketogenesis, but unexpectedly develop hypoglycemia | Mus musculus |

additional information | Mus musculus | DECR may also play a role in the degradation of fatty acids containing odd-numbered double bonds because the intermediate 2,5-dienoyl-CoA may be isomerized by enoyl-CoA isomerase to 3,5-dienoyl-CoA and then converted to 2,4-dienoyl-CoA by a specific delta3,5,delta2,4-dienoyl-CoA isomerase | ? | - |

additional information | Mus musculus | in eukaryotes, double bonds in even-numbered positions are reduced by an NADPH-dependent 2,4-dienoyl-CoA reductase to 3-enoyl-CoA, which is then isomerized by enoyl-CoA isomerase to trans-2-enoyl-CoA, suitable for further oxidation | ? | - |

additional information | - |
analysis of liver fatty acids after the mice are fasted for 24 h indicates that fasting has a minor effect on the lipid content of wild type liver, with an overall increase of 29% in the concentration of fatty acids, in Decr-/- mice, the overall concentration of fatty acids increases by 108% after fasting | Mus musculus |
additional information | - |
Decr-/- mice show decreased blood glucose and elevated non-esterified fatty acids concentrations after fasting in comparison to wild type mice | Mus musculus |
additional information | - |
fasting increases the total concentration of acylcarnitines by 2fold in wild type mice (567 nM), in Decr-/- mice, a markedly higher 9fold increase is observed (2150 nM) | Mus musculus |
additional information | - |
immunoblotting of mitochondrial extracts from liver, muscle and heart with an antibody against human DECR reveals a detectable signal from wild type mice, whereas no signal can be detected for homozygous null mutant mice | Mus musculus |
additional information | - |
in Decr-/- mice, the overall concentration of fatty acids increases by 108% after fasting, the most profound changes between fasted wild type and Decr-/- mice are observed for the levels of palmitoleic acid (C16:1), oleic acid, linolenic acid (C18:3) and linoleic acid, which are 2.5- to 3.8fold higher in Decr-/- mice, in comparison to the fed state, the concentrations of monounsaturated fatty acids and polyunsaturated fatty acids increase by 288% and 254%, respectively | Mus musculus |
additional information | - |
mitochondrial 2,4-dienoyl-CoA reductase activity in mice is indispensable for the complete oxidation of (poly)unsaturated fatty acids and for adaptation to metabolic stress | Mus musculus |
