FIGURE 4.

Hepatic PC is a quantitatively important source of hepatic TG. Twenty-four hours after intravenous injection of [³H]PC-HDL into Pemt^−/− (A) or Ctα^−/− (B) mice and their controls, livers were collected, and the specific activities (dpm/nmol) of hepatic PC and TG were calculated. The contribution of PC to the total hepatic TG pool was calculated by dividing the specific activity of hepatic TG by the specific activity of hepatic PC. Values represent means ± S.E. (error bars) (n = 4–6 per group). *, p < 0.05.
