Characteristics of retinol accumulation from serum retinol-binding protein by cultured Sertoli cells [PDF]

, 1989
The uptake of retinol was examined in cultured Sertoli cells when retinol was provided as a complex with the transport protein retinol-binding protein (RBP). Sertoli cells accumulated [3H]retinol in a time- and temperature-dependent manner. At 32 °C, the

Factors that affect placental retinol transfer in preterm infants and mothers with retinol deficiency

, 2021
Background/aim: The retinol level and retinol delivery to the placenta may vary depending on various factors involving the mother andnewborn. The present study evaluates the factors affecting retinol levels in newborns and the transplacental retinol ...

Flavin Catalysts in Organic Synthesis

Angewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Decreases in retinol and retinol-binding protein during total parenteral nutrition in rats are not due to a vitamin A deficiency

Journal of Lipid Research, 1996
Perfusion feeding in rats induced a decrease in circulating retinol despite an adequate supply of vitamin A. We studied the effect of total parenteral nutrition (TPN) on the retinol specific carrier in rat, analyzing holo-RBP (bound to retinol) and apo ...

Retinol esterification in Sertoli cells by lecithin-retinol acyltransferase [PDF]

, 1989
Esterification of retinol occurs during the metabolism of vitamin A in the testis. An acyl- CoA:retinol acyltransferase (ARAT) activity has been described for microsomes isolated from testis homogenates. That activity was also observed here in microsomal

Retinol-Binding Protein Interferes with Transthyretin-Mediated β‑Amyloid Aggregation Inhibition

, 2018
β-Amyloid (Aβ) aggregation is causally linked to Alzheimer’s disease. On the basis of in vitro and transgenic animal studies, transthyretin (TTR) is hypothesized to provide neuroprotection against Aβ toxicity by binding to Aβ and inhibiting its ...
