Relatively reduced serum cholesterol levels in ACAT1^–/–LDLR^–/– mice compared with ACAT1^+/+LDLR^–/– mice. (a) Serum cholesterol levels in mice fed an atherogenic diet for 2 months. (b) Total cholesterol levels in pooled serum (n = 5 in each group) fractionated by FPLC. VLDL, very low density lipoproteins; IDL, intermediate density lipoproteins; LDL, low density lipoproteins; HDL, high density lipoproteins. Triangles represent values for male mice and circles represent values for females.
