原始语种摘要: Abstract(#br)Carotene-15,15′-monooxygenase (CMO-I) cleaves β -carotene to form vitamin A, whereas carotene-9′,10′-monooxygenase (CMO-II) preferentially cleaves non–provitamin A carotenoids. Recent reports indicate that β -carotene metabolites regulate dietary lipid uptake, whereas lycopene regulates peroxisome proliferator-activated receptor expression. To determine the physiologic consequences of carotenoids and their interactions with CMO-I and CMO-II, we characterized mammalian carotenoid metabolism, metabolic perturbations, and lipid metabolism in female CMO-I −/− and CMO-II −/− mice fed lycopene or tomato-containing diets for 30 days. We hypothesized that there would be significant interactions between diet and genotype on carotenoid accumulation and lipid parameters. CMO-I −/− mice...
