This study investigated effects of xanthophylls (containing 40% lutein and 60% zeaxanthin) on gene expression of inflammatory mediators ( [] and []) and apoptosis ( [] and ) of breeding hens and chicks. In Exp. 1, 432 hens were divided into 3 groups and fed diets supplemented with 0 (as the control
Background: Fucoxanthin (FX), a xanthophyll pigment which occurs in marine brown algae with remarkable biological properties, has been proven to be safe for consumption by animals. Although FX has various pharmacological effects including anti-inflammatory, anti-tumor, anti-obesity,
Various inflammatory stimuli are able to modify or even "re-program" the mitochondrial metabolism that results in generation of reactive oxygen species. In noncommunicable chronic diseases such as atherosclerosis and other cardiovascular pathologies, type 2 diabetes and metabolic syndrome, these
Oxidative and inflammatory processes play a major role in stress-induced neural atrophy. There is a wide body of literature linking oxidative and inflammatory stress with reductions in neurotrophic factors, stress resilience, and cognitive function. Based on their antioxidant and The present study investigated the effects of xanthophylls (containing 40 % of lutein and 60 % of zeaxanthin) on proinflammatory cytokine (IL-1β, IL-6, interferon (IFN)-γ and lipopolysaccharide-induced TNF-α factor (LITAF)) and anti-inflammatory cytokine (IL-4 and IL-10) expression of breeding hens
Astaxanthin is a xanthophyll carotenoid, which possesses strong scavenging effect on reactive oxygen species. In this study, we examined the effect of astaxanthin on dextran sulfate sodium (DSS)-induced colitis in mice. Experimental colitis was induced by the oral administration of 4% w/v DSS in tap
Lutein and zeaxanthin are the only carotenoids present in the eye. They cannot be synthesized de novo and are specifically concentrated in the macula. They appear to have at least two major functions: to filter out blue light and thus prevent ensuing damages to the eye and to act as antioxidants.
The exploitation of marine organisms for human nutritional and pharmaceutical purposes has revealed important chemical prototypes for the discovery of new drugs, stimulating compounds isolation and syntheses of new related compounds with biomedical application. Nowadays, it is well known that
Retinopathy of prematurity (ROP) and diabetic retinopathy (DR) are important causes of blindness among children and working-age adults, respectively. The development of both diseases involves retinal microvascular degeneration, vessel loss and consequent hypoxic and inflammatory pathologic retinal
Exposure of human skin to ultraviolet (UV) radiation causes significant damage to that tissue. The effects of UV on the skin mainly include acute inflammation (erythema/edema) and abnormal keratinization wherein prostaglandin E2 (produced by cyclooxygenase-2), interleukin-8 and transglutaminase 1 (a
Generation of singlet oxygen by solar ultraviolet (UV) radiation causes acute inflammatory responses in the skin. Accumulation of singlet-oxygen-quenching antioxidants in the skin can suppress this photo-oxidative stress. This study evaluated the effect of dietary xanthophylls from red paprika fruit
Mastitis is a major inflammatory response of the mammary gland due to various pathogenic invasions and is a serious disease that affects the production yield and health status of cows. Astaxanthin (AST), a xanthophyll carotenoid, is a secondary metabolite synthesized by microalgae and yeasts that
This review compares and contrasts the role of carotenoids across the taxa of life-with a focus on the xanthophyll zeaxanthin (and its structural isomer lutein) in plants and humans. Xanthophylls' multiple protective roles are summarized, with attention to the similarities and differences in the
We recently showed that astaxanthin (ASX), a xanthophyll carotenoid, activates phosphatidylinositol 3-kinase pathway of insulin signaling and improves glucose metabolism in liver of high fructose-fat diet (HFFD)-fed mice. The aim of this study is to investigate whether ASX influences phosphorylation
