Cellular TG levels in Huh-7 cells increase after incubation with HDL-PC. Huh-7 cells were incubated for 4 h in serum-free DMEM with or without human HDL (final concentration of PC, 2 mm). Cells were harvested, lipids were extracted, and cellular TG concentrations were measured. Values are means ± S.E. (error bars) of three independent experiments, each performed in triplicate. *, p < 0.05.
