RNA-seq of full thickness small intestine from wild type mice that were either exposed or not with western diet for 8 weeks

We found that western diet consumption resulted in decrease in the percentage of normal Paneth cell population in wild type mice, indicating that western diet negatively regulates Paneth cell homeostasis. We performed transcriptional profiling to identify molecular mechanisms associated with Paneth cell defect in wild type mice exposed to western diet. Male mice were used at 4-5 weeks of age, and were fed with either standard or western diet. The whole ileum of the mice were harvested for transcriptomic analysis after completing 8 weeks of diet consumption.
