The purpose of this study is to determine the impact of curcumin, administrated orally, on iron metabolism in healthy volunteers. Iron metabolism will be describe by hepcidin expression that the investigators observed in vitro and serum hepcidin levels.
Name: curcuma longa
Description: Iron, ferritin, transferrin, transferrin saturation
Measure: Plasmatic iron bioavailability Time: 30min, 1H, 2H, 3H, 4H, 6H, 8H, 12H, 24H et 48HDescription: In vitro: the coculture model that we previously developed to analyze endogenous hepcidin expression, and human hepatic cells line (HepG2) stimulated or not by IL-6 which governs the STAT3 pathway, transfected with gene reporter constructs containing hepcidin promoter.
Measure: Evaluation of the inhibitory activity of volunteers's serum on hepcidin expression by hepatocytes Time: 30min, 1h, 2h, 3h, 4h, 6h, 8h, 12h, 24hAllocation: Randomized
Crossover Assignment
There is one SNP
In vitro: the coculture model that we previously developed to analyze endogenous hepcidin expression, and human hepatic cells line (HepG2) stimulated or not by IL-6 which governs the STAT3 pathway, transfected with gene reporter constructs containing hepcidin promoter..
