Gene expression in hearts of mice fed a high fat diet

To understand the impact of high fat diet on gene expression in mouse hearts, a micro-array analysis was carried out Male mice at age of 4 weeks were maintained on either a high fat diet (60% kcal from fat, HFD) or standard chow diet (normal diet, ND) for 4 months. Mice were sacrificed by the end of the 4th months with hearts harvested and subjected to micro-array analysis
