Expression data from colons of mice fed psyllium fiber

Feeding dietary fiber is known to provide us many beneficial effects. We used microarrays to detail the changes of gene expression in colons of mice fed the psyllium fiber for 5 days. Mice were devided into 2 groups, control and psyllium fiber. The psyllium fiber group fed the diet containing 10% psyllium for 5 days, whereas the control groups fed the diet without psyllium fiber. Total RNA were extracted from mouse colons and applied to the microarrays.
