Concerted action of human chorionic gonadotropin and norepinephrine on intracellular-free calcium in human granulosa-lutein cells [PDF]
, 1993 Luteal cells are known to possess receptors for LH/hCG and receptors of the beta-adrenergic type. Interactions of specific agonists with either receptor lead to the activation of adenylate cyclase and subsequently to an increase of cAMP.

Effect of oxytocin on free intracellular Ca2+ levels and progesterone release by human granulosa-lutein cells [PDF]
, 1993 Oxytocin and its receptor are found in the corpus luteum in a variety of species, including the human. In the present study we used fura-2 microfluorimetry to investigate whether activation of the oxytocin receptor of cultured human granulosa-lutein ...

Orientation of lutein in a lipid bilayer : revisited [PDF]
, 2012 Lutein is present in the human retina and lens, where it plays a protective role. As lutein is associated with the lipid matrix of biomembranes, the role depends on its membrane location.

Effects of abiotic stressors on lutein production in the green microalga Dunaliella salina. [PDF]
, 2014 BackgroundRecent years have witnessed a rising trend in exploring microalgae for valuable carotenoid products as the demand for lutein and many other carotenoids in global markets has increased significantly.

Photo-stability of lutein in surfactant-free lutein-zein composite colloidal particles
Food Chemistry: X, 2020 The ability of nanoparticles from the plant protein zein to protect lutein from light degradation was studied under various conditions. Lutein-zein nanoparticles were synthesized, after zein purification, by anti-solvent precipitation.

Carotenoids and antioxidant enzymes as biomarkers of the impact of heavy metals in food chain [PDF]
, 2016 Antioxidant enzymes (catalase and peroxidase) and carotenoids (lutein and â-carotene) are often used as biomarkers of metal contamination of water and agricultural soils.

Metabolites, 2023 Lutein, the most abundant carotenoid in the infant eye and brain, is critical for their visual and cognitive development. Due to its lipophilic nature, a high adiposity may affect the tissue distribution of lutein.

Carbachol increases intracellular free calcium concentrations in human granulosa-lutein cells [PDF]
, 1992 We investigated whether the stimulation of human granulosa-lutein cells with muscarinic and nicotinic receptor agonists can cause increases in intracellular free calcium (Ca2+), using Fura-2 microfluorimetry.
