Effect of ox-ApoE on triglyceride, cholesterol and PC efflux from foam cells.

A. Cellular triglyceride efflux by native and ox-ApoE. B. Cellular cholesterol efflux by native and ox-ApoE. C. Cellular PC efflux by native and ox-ApoE. D. Detection of triglycerides in supernatant. E. Detection of cholesterol in supernatant. F. Detection of PC in supernatant. THP-1 cells were loaded with lipids as described in Materials and Methods. Efflux of triglycerides, cholesterol, and PC was initiated by addition of native or ox-ApoE in cultured foam cells. After treatment of 9 hrs, triglycerides, cholesterol, and PC in supernatant were measured by the respect kit. After treatment of 24 hrs, the cellular triglycerides, cholesterol, and PC were measured with the respect kit. Tg: triglycerides; Ch: cholesterol; PC: phosphatidylcholine. Data are shown as means ± SEM; *p<0.05 vs. PBS group. n = 3.
