Effect of 20% fructose feeding and dietary salt on RNA expression in the renal cortex of rats

Elevated fructose consumption has been associated with metabolic and renal diseases. It is controversial whether kidney problems are a result of systemic metabolic disease or stem, at least in part, from changes due to local fructose metabolism. To study the short-term effect of fructose on genetic programs in renal proximal tubules, the diet for rats in experimental groups was supplemented for 7 days with 20% fructose in the drinking water. Two sets of 8 rats each on different baseline rodent diets were used in this study. 4 animals of each set received fructose in the drinking water while the other 4 served as controls. Animals were sacrificed after the experimental period of 7 days and slices of superficial kidney cortex were used for total RNA extraction. The RNA was analyzed with Affymetrix RaGene-2_0-st.
