Journal ArticleDOI
β-Carotene Is an Important Vitamin A Source for Humans
Tilman Grune,Georg Lietz,Andreu Palou,A. Catharine Ross,Wilhelm Stahl,Guangweng Tang,David I. Thurnham,Shi An Yin,Hans Konrad Biesalski +8 more
TL;DR: Experts in the field of carotenoids met at the Hohenheim consensus conference in July 2009 to elucidate the current status of β-carotene research and to summarize the current knowledge with respect to the chemical properties, physiological function, and intake.
Journal ArticleDOI
Biomarkers of Nutrition for Development (BOND)—Vitamin A Review
Sherry A. Tanumihardjo,Robert M. Russell,Charles B. Stephensen,Bryan M Gannon,Neal E. Craft,Marjorie J Haskell,Georg Lietz,Kerry Schulze,Daniel J Raiten +8 more
TL;DR: A review of biomarkers for vitamin A status assessment is presented in this article, where the authors describe the clinical and functional indicators related to eye health and biochemical biomarkers (i.e., RBP, breast-milk retinol, dose-response tests, isotope dilution methodology, and serum retinyl esters).
Journal ArticleDOI
Two common single nucleotide polymorphisms in the gene encoding β-carotene 15,15′-monoxygenase alter β-carotene metabolism in female volunteers
W. C. Leung,Susanne Hessel,Catherine Méplan,James E. Flint,Vitus Oberhauser,Franck Tourniaire,John E. Hesketh,J. von Lintig,Georg Lietz +8 more
TL;DR: Screening of the total open reading frame of the BCMO1 coding region led to the identification of two common nonsynonymous single nucleotide polymorphisms (R267S: rs12934922; A379V: rs7501331), which may provide an explanation for the molecular basis of the poor converter phenotype within the population.
Journal ArticleDOI
Effect of sex and genotype on cardiovascular biomarker response to fish oils: the FINGEN Study
Muriel J. Caslake,Elizabeth A. Miles,Bettina M. Kofler,Georg Lietz,Peter J. Curtis,Christopher K. Armah,Alan Kimber,Jilly P Grew,Lesley Farrell,Julie Stannard,Frances L. Napper,Aleix Sala-Vila,Annette L. West,John C. Mathers,Chris J. Packard,Christine M. Williams,Philip C. Calder,Anne Marie Minihane +17 more
TL;DR: The results of the current trial, which used a prospective recruitment approach to examine the responses in population subgroups, are indicative of a greater triacylglycerol-lowering action of long-chain n-3 polyunsaturated fatty acids in males than in females.
Journal ArticleDOI
Beta-Carotene Reduces Body Adiposity of Mice via BCMO1
Jaume Amengual,Jaume Amengual,Erwan Gouranton,Yvonne G. J. van Helden,Susanne Hessel,Joan Ribot,Evelien Kramer,Beata Kieć-Wilk,Ursula Razny,Georg Lietz,Adrian Wyss,Aldona Dembinska-Kiec,Andreu Palou,Jaap Keijer,Jean-François Landrier,M. Luisa Bonet,Johannes von Lintig,Johannes von Lintig +17 more
TL;DR: An important role of BC is evidences for the control of body adiposity in mice and Bcmo1 is identified as critical molecular player for the regulation of PPARγ activity in adipocytes.
