Exposure to 10 nM ouabain for two days did not significantly change PPARG or LPL expression (Fig. 5A), but a four-day exposure resulted in a 2.5-fold decrease in PPARG and 3.7-fold decrease in LPL expression (Fig. 5B, p<0.02) compared to untreated AD. This evidence concerns the gene LPL and Alzheimer disease.
