Uptake and metabolism of retinol (vitamin A) in the isolated perfused rat liver

open access: yesJournal of Lipid Research, 1965
The isolated perfused liver was employed to study various aspects of retinol-C14 metabolism. The rate of uptake of retinol, retinal, retinoic acid, and retinol acetate was rapid (first-order rate constant, k = 0.12–0.16 min−1) during the first 3–10 min ...

A multicompartmental model of vitamin A kinetics in rats with marginal liver vitamin A stores.

open access: yesJournal of Lipid Research, 1985
A linear, first-order, constant-coefficient multicompartmental model is presented which describes the dynamics of [3H]retinol turnover in adult rats with normal plasma retinol concentrations but low liver stores (less than 100 micrograms of retinol ...

Retinol esterification by mammary gland microsomes from the lactating rat.

open access: yesJournal of Lipid Research, 1982
Because vitamin A in milk is largely present as esterified retinol while blood plasma predominantly contains unesterified retinol, experiments were conducted to determine whether membranes from the lactating mammary gland are able to synthesize retinyl ...

Downregulation of Fzd6 and Cthrc1 and upregulation of olfactory receptors and protocadherins by dietary beta-carotene in lungs of Bcmo1-/- mice. [PDF]

open access: yes, 2010
An ongoing controversy exists on beneficial versus harmful effects of high beta-carotene (BC) intake, especially for the lung. To elucidate potential mechanisms, we studied effects of BC on lung gene expression.
