Study of the effect on indoxyl sulfate on endothelial gene expression

The aim of this study is to determine the molecular mechanism by which indoxyl sulfate acts on endothelial cells. Endothelial cells (HUVECs) were incubated with medium containing indoxyl sulfate at concentration found in chronic kidney disease patients (1mM). Since indoxyl sulfate is a potassium salt, control medium contains KCl at 1mM. Cells were incubated during four hours in presence of indoxyl sulfate or KCl. Seven biological replicates were obtained for these two conditions. To understand how uremic solutes participate in endothelial dysfunction and cardiovascular complications of chronic kidney disease patients
