Figure 6From: α-Tocopherol modulates the low density lipoprotein receptor of human HepG2 cellsThe effect of α-tocopherol on the cellular concentration of cholesterol and lathosterol of HepG2 cells. Cells were incubated for 24 h at 37°C in media containing the indicated concentrations of α-tocopherol. Cellular cholesterol (●) and lathosterol (▲) were measured in duplicates by GC as described in Methods and materials and the data was expressed relative to the values of control cells not pretreated with α-tocopherol set at 100%. The cholesterol concentration in control cells was 9 mg/mg cell protein and the lathosterol concentration was 13 μg/mg cell protein.Back to article page
