Here we demonstrate that the catabolism PR:PROJECT_SUMMARY of membrane phosphatidylcholine (PC) into water-soluble glycerophosphocholine PR:PROJECT_SUMMARY (GPC) by the phospholipase/lysophospholipase PNPLA8-PNPLA7 axis enables PR:PROJECT_SUMMARY endogenous choline stored in hepatic PC to be utilized in methyl metabolism. PR:PROJECT_SUMMARY PNPLA7-deficient mice show marked decreases in hepatic GPC, choline, and several PR:PROJECT_SUMMARY metabolites related to the methionine cycle, accompanied by various signs of PR:PROJECT_SUMMARY methionine insufficiency including growth retardation, hypoglycemia, PR:PROJECT_SUMMARY hypolipidemia, increased energy consumption, reduced adiposity, increased FGF21, PR:PROJECT_SUMMARY and an altered histone/DNA methylation landscape. Moreover, PNPLA8-deficient PR:PROJECT_SUMMARY mice recapitulate most of these phenotypes. In contrast to wild-type mice fed a PR:PROJECT_SUMMARY methionine/choline-deficient diet, both knockout strains display a decreased PR:PROJECT_SUMMARY hepatic triglyceride likely via reductions of lipogenesis and GPC-derived PR:PROJECT_SUMMARY glycerol flux. Collectively, our findings highlight the biological importance of PR:PROJECT_SUMMARY phospholipid catabolism driven by PNPLA8/PNPLA7 in methyl group flux and PR:PROJECT_SUMMARY triglyceride synthesis in the liver.
