Hence, deficiency of PC in the
liver did not provide the protection observed in Pemt−/− mice fed the
high-fat diet.
In contrast, the deficiency of choline biosynthesis provided
the beneficial effect.Moreover, when Pemt+/+ micewere fed a cholinedeficient
diet for 12 weeks, these mice were also protected from dietinduced
obesity/insulin resistance [84].
These data are consistent with
the finding that when obese mice were fed either a CD or a choline-
