Loss of Retinol-Binding Properties for Plasma Retinol-Binding Protein in Normal Human Epidermis [PDF]
Terminal differentiation of the keratinocytes (cornification) has been linked to a restricted supply of retinol. Retinol is distributed to target cells by the retinol-binding protein (RBP), which circulates in the plasma in complex with transthyretin (TTR).

Structural and functional studies of intrinsically disordered fibronectin-binding proteins [PDF]
Bacterial fibronectin-binding proteins (FnBPs) mediate adhesion of bacteria to host tissues through binding to the human protein fibronectin (Fn). FnBPs are predicted to contain a series of intrinsically disordered Fn-binding repeats (FnBRs), which ...

Vitamins and Chronic Wounds: How Altered Pharmacokinetics and Comorbidities Contribute to Vitamin Deficiencies. [PDF]
ABSTRACT Wound healing is complex and requires adequate amounts of macro‐ and micronutrients. When wound healing is delayed, a wound is considered chronic. Increasing evidence shows that vitamin deficiencies are prevalent in patients with chronic wounds, yet intervention studies with vitamin supplementation yielded inconsistent effects.

Effect of Dietary Vitamin A, Breed, and Kidney Function on the Onset of Urinary Vitamin A Excretion and the Vitamin A Transport Complex in Growing Dogs. [PDF]
ABSTRACT Vitamin A (retinol and retinyl esters) is present in substantial amounts in the urine of healthy adult dogs, but the mechanisms affecting its excretion are poorly understood. To assess whether the onset of urinary vitamin A excretion is dependent on dietary vitamin A intake, breed, and/or parameters of kidney function, 48 puppies from two ...

Proteo-Metabolomic Profiling of PMM2-CDG Reveals Dysregulation of Retinoic Acid Synthesis, Myo-Inositol, and the Hexosamine Pathway. [PDF]
ABSTRACT Phosphomannomutase deficiency (PMM2‐CDG), the most common congenital disorder of glycosylation (CDG), is characterized by multisystem involvement and a lack of disease‐modifying therapies. While previous transcriptomic studies have uncovered disrupted cellular pathways, the functional consequences of these alterations remain poorly understood.

Tissue distribution of the receptor for plasma retinol-binding protein [PDF]
The tissue distribution of the retinol-binding-protein receptor has been studied by using a cell-free binding assay. High binding activity was found in placenta, retina pigment epithelial cells, bone marrow and kidneys. Specific binding activity was also found in the small intestines, spleen and liver, and to a lesser extent in lung. Scatchard analysis

Retinol-binding protein: the transport protein for vitamin A in human plasma [PDF]
Vitamin A circulates in human plasma as retinol bound to a specific transport protein. This protein differs from the known low and high density plasma lipoproteins and has a hydrated density greater than 1.21. In order to study this protein, volunteers were injected intravenously with retinol-15-(14)C.

Mapping the interactions of dengue virus NS1 protein with human liver proteins using a yeast two-hybrid system: identification of C1q as an interacting partner. [PDF]
Dengue constitutes a global health concern. The clinical manifestation of this disease varies from mild febrile illness to severe hemorrhage and/or fatal hypovolemic shock.

Transthyretin (TTR) is a plasma homotetrameric protein that transports thyroxine and retinol. TTR itself, under pathological conditions, dissociates into partially unfolded monomers that aggregate and form fibrils.
