Fat-soluble vitamin intestinal absorption: absorption sites in the intestine and interactions for absorption.
Aurélie Goncalves,Stéphanie Roi,Marion Nowicki,Amélie Dhaussy,Alain Huertas,Marie-Josèphe Amiot,Emmanuelle Reboul,Emmanuelle Reboul,Emmanuelle Reboul +8 more
TL;DR: The interactions occurring at the intestinal level between the fat-soluble vitamins A, D, E and K (FSVs) are poorly documented and significant competitive interactions for uptake were elucidated, supporting the hypothesis of common absorption pathways.

TL;DR: It is demonstrated for the first time that intestinal scavenger receptors participate in the absorption of dietary phylloquinone in mice overexpressing SR-BI compared with controls.

TL;DR: The data reported here show for the first time that FAs can interact with cholecalciferol intestinal absorption at different key steps of the absorption process, and may thus be optimized according to oil FA composition.

Cluster-determinant 36 (CD36) impacts on vitamin E postprandial response.
Aurélie Goncalves,Aurélie Goncalves,Aurélie Goncalves,Stéphanie Roi,Stéphanie Roi,Stéphanie Roi,Marion Nowicki,Marion Nowicki,Marion Nowicki,Isabelle Niot,Emmanuelle Reboul,Emmanuelle Reboul,Emmanuelle Reboul +12 more
TL;DR: These findings show for the first time that CD36 participates-directly or indirectly-in vitamin E uptake, and thatCD36 effect on postprandial lipid metabolism in turn modifies vitamin E postpr andial response.

TL;DR: In Abcgl-deficient mice, vitamin E concentration was reduced in plasma lipoproteins whereas most tissues displayed a higher vitamin E content compared to wild-type mice.
