22This study is designed to assess the effect of a new PPARgamma modulator on the expression and activity of the lactase enzyme in human intestinal epithelial cells. Based on their previous experimental results, the investigators hypothesized that modulating intestinal PPARgamma activity is a new pharmacological mechanism allowing the control of lactase expression and activity in the gut
Four duodenal biopsies will be collected. Two biopsies will stimulated with GED (PPARgamma modulator) ex vivo during 6 hours. Two biopsies will be unstimulated (control).
