General Information

EC Number General Information Comment Organism
1.13.11.63 malfunction cardiac dysfunction in beta-carotene-15,15-dioxygenase-deficient mice is associated with altered retinoid and lipid metabolism. Bco1-/- mice show an increase in heart levels of retinol, nonesterified fatty acids, and ceramides and a decrease in heart triglycerides. These lipid changes are accompanied by elevations in levels of genes important to retinoid metabolism, specifically retinol dehydrogenase 10 and retinol-binding protein 4, as well as genes involved in lipid metabolism, including peroxisome proliferator-activated receptor-gamma, lipoprotein lipase, Cd36, stearoyl-CoA desaturase 1, and fatty acid synthase. The mutant mice show compromised heart function. But the total absence of Bco1 does not substantially affect beta-apo-carotenoid concentrations in the heart. Phenotype, overview Mus musculus
1.13.11.63 physiological function dietary carotenoids like beta-carotene are converted within the body either to retinoid, via beta-carotene-15,15'-dioxygenase (BCO1), or to beta-apo-carotenoids, via beta-carotene-9',10'-oxygenase 2. Some beta-apo-carotenoids are potent antagonists of retinoic acid receptor (RAR)-mediated transcriptional regulation, which is required to ensure normal heart development and functions. BCO1 modulates heart metabolism and function, possibly by altering levels of cofactors required for the actions of nuclear hormone receptors Mus musculus
