Cluster-determinant 36 (CD36) impacts on vitamin E postprandial response

International audience; Scope: A single nucleotide polymorphism in the cluster determinant 36 (CD36) gene has recently been associated with plasma alpha-tocopherol concentration, suggesting a possible role of this protein in vitamin E intestinal absorption or tissue uptake. Methods and results: To investigate the involvement of CD36 in vitamin E transport, we first evaluated the effect of CD36 on alpha- and gamma-tocopherol transmembrane uptake and efflux using transfected HEK cells. gamma-Tocopherol postprandial response was then assessed in CD36-deficient mice compared with wild-type mice, after the mice had been fully characterized for their alpha -tocopherol, vitamin A and lipid plasma,…
