Lutein and Astaxanthin Supplementation Induce Competitive Inhibition of Carotenoid Deposition in Egg Yolk

open access: yesAnimals
Lutein- and astaxanthin-fortified eggs can greatly improve both nutritional and economic values of eggs. High doses of lutein and astaxanthin are often supplemented in hen diets to rapidly accumulate lutein and astaxanthin in eggs.

Enrichment of Eggs with Lutein

open access: yesPoultry Science, 2004
Lutein is being considered as a nutrient for prevention of macular degeneration in the aging population. Two experiments were designed to study the transfer efficiency of lutein from the layers' diet into the egg. In experiment 1, laying hens were fed corn-soy diets supplemented with 0, 125, 250, 375, 500, 625, 750, or 1000 ppm of lutein.

Molecular mechanisms of luteinization [PDF]

open access: yesObstetrics & Gynecology Science, 2014
Dynamic changes in steroidogenesis occur in ovarian granulosa cells during ovulation after the LH surge. The ovulatory LH surge induces rapid up-regulation of steroidogenic acute regulatory (StAR) protein and rapid down-regulation of aromatase (Cyp19a1) in granulosa cells undergoing luteinization during ovulation.
