eNOS, NOX, XO we will incubate endothelial cells with plasma or serum from subjects. Then we will measure the sus-mentionned enzymes' expression.

We will perform proteomics or metabolomics analysis directly on serum from participants and also on lysate of endothelial cells pre-incubated with plasma or serum from participants.

This is a prospective, randomized, placebo-controlled, double-blinded and 3 ways cross-over study.
Three populations : healthy male subjects under 40 y [1] ; healthy male and female participants between 40 and 65 years [2] and subjects with hypertension [3]. Minimum 15 participants in each group are needed.
The populations 2 and 3 will be studied together with subgroups analyses of the results for the status of hypertension, of treatment, age and gender.
For 5 subjects in each group, we will perform a fourth session with Placebo PO and Rasburicase IV. That session will be non-randomized and blinded only for the subject.

Febuxostat and Rasburicase will be prepared by an independant pharmacist.
