homeostasis/metabolism
• in controls, main cholesterol carrier is HDL and only ~10% is contained in the VLDL/LDL-sized fraction, while in mutants, most of the cholesterol (71%) is found in VLDL/LDL-sized fractions

• on a normal chow diet, mice are severely hypercholesterolemic compared to controls (12.5 mM vs 2.9 mM in controls)
• on mild high-fat/cholesterol (HFC) diet with 15% fat/0.25% cholesterol, serum cholesterol is increased 8-fold (to 31mM from 3.8 mM) with most of the increase found in VLDL/LDL-sized fractions
