Possible Interacting Proteins for Retinol Binding Protein and Cellular Retinol Binding Protein
Retinol or vitamin A is crucial for many biological processes in the body such as proliferation, differentiation and reproduction. It is mainly stored in the liver and can be broken down to retinoic acid inside the cell. It travels in the circulatory system attached to Retinol Binding Protein (RBP) …

Investigations on extra- and intracellular retinol-binding proteins
… vitamin A, which is chemically referred to retinol (ROH), is known to be essential for the process of vision, the immune system but also for cell differentiation and proliferation. Recently, ROH itself has been reported to be involved in adipogenesis and a ROH transport protein, the …

All- trans-retinol modulation of chemically-induced pulmonary and hepatic toxicity
… enhanced release of reactive oxygen species from retinol-primed Kupffer cells. However, in the lung it has been shown that retinol can protect against many of the inflammatory effects caused by bleomycin. Whether or not retinol pretreatment can modulate chemical-induced injury of compounds that …

The effect of Retinol Binding Protein on the Proteome of muscle cells.
… for normal embryonic development and vision. Retinol binding protein (RBP) and its receptor, STRA6, are vital for the maintenance of intracellular stores of vitamin A. Recently, elevated serum RBP concentration has been implicated as a contributing factor to the development of insulin …

Developmental and estrogen regulation of Xenopus laevis retinol-binding protein gene expression
… regulation of the estrogen-regulated serum retinol-binding protein and estrogen receptor genes in Xenopus embryonic livers has been examined. Serum retinol binding protein (RBP) mRNA is detected exclusively in liver tissue in both adult Xenopus laevis and in tadpoles. RBP mRNA is absent in …

Cloning and Estrogen Regulation of the Retinol Binding Protein Messenger-Rna of Xenopus Laevis
… homology alignment with the sequence for human retinol binding protein, the clone was identified as the mRNA for serum retinol binding protein of Xenopus. Since we wished to use this gene to study hormone regulation, it was important to establish its hormone regulation in vivo. Therefore, I …

An investigation of the association of colonic adenomatous polyps and nutritional status of retinol and carotene
… that lower dietary consumption of carotene or retinol or lower serum levels of beta carotene or retinol are associated with development of colonic adenomas. To evaluate this hypothesis, selected patients who were to undergo colonoscopy to determine polyps status were asked to undergo a battery …

Investigations of the action of vitamin A and beta carotene on reproductive performance in pigs
… Investigations on the treatment of sows with retinol proprionate or retinol palmitate and their effect on reproductive function were undertaken. The objectives of this work were to investigate the transport and storage of this vitamin after injection, the mode of action of retinol on the ovary …

Establishment of retinoic acid gradients in the early development of Xenopus laevis
… (ZNS). Die Synthese von RA aus Vitamin A (Retinol) läuft in zwei Schritten ab, wobei die zweite Reaktion- katalysiert von Retinal-Dehydrogenasen (RALDHs)- lange als entscheidend für die gewebsspezifische Produktion von RA im Embryo angesehen wurde. Das kürzlich identifizierte Xenopus …

Estado nutricional de vitamina A em idosos do município de Camaragibe-PE, 2003
… A foi avaliado pelas concentrações séricas de retinol e pelo inquérito de freqüência do consumo de alimentos-fonte de vitamina A. Na avaliação do estado nutricional protéico energético, foi utilizado o Índice de Massa Corporal (IMC). A prevalência de hipovitaminose A (retinol sérico < 1,05 …

Effect of Nutrition and Management on Marbling Deposition, Carcass Value, and Profitability in Feedlot Cattle
… dietary vitamin A on carcass quality and serum retinol (ROL) in cattle. Diets were calculated to contain 2300 (LVA) or 7250 IU/kg (HVA). No treatment differences existed for MS across all trials. Serum ROL was greater among calf-fed heifers and steers fed HVA. Serum ROL and MS were not …

The Interactions for the RBP Receptor, Stimulated by Retinoic Acid Gene 6
Vitamin A, or retinol, is a fat-soluble vitamin, essential for many important processes including proliferation, reproduction, vision and immunocompetence. Retinol binding protein (RBP) is the principal carrier of retinol in the blood from its storage site, the liver, to retinol dependant tissues. …
