• at 16 weeks of age after 10 weeks on a western style diet only 52% of mice survive compared to 100% survival for diet matched Ldlr single mutants

homeostasis/metabolism

increased circulating glucose level ( J:83615 )

• the level after 10 weeks on a western diet is higher than in diet matched Ldlr single mutants

decreased circulating cholesterol level ( J:83615 )

• cholesterol levels after 6 and 10 weeks on a western diet are lower than in diet matched Ldlr single mutants

cardiovascular system

atherosclerotic lesions ( J:83615 )

• on a western style diet, lesions are 2.0 fold greater at the arch and 4.1 fold greater at the thoracic aorta compared to diet matched Ldlr single mutants
