Triacylglycerol synthesis is initiated by glycerol-3-phosphate acyltransferase (GPAT). Of four isoforms, GPAT1 contributes 30\u201350% of total liver GPAT activity, and we hypothesized that it might influence liver susceptibility to tumorigenesis. C57Bl\/6 mice deficient in GPAT1 were backcrossed 6 times to C3H mice. After exposure to the carcinogen diethylnitrosamine (DEN) and the tumor promoter phenobarbital, male Gpat1\n                    <jats:sup>-\/-<\/jats:sup>\n                    mice, compared with controls ( Gpat1\n                    <jats:sup>+\/+<\/jats:sup>\n                    ), had 93% fewer macroscopically visible nodules per liver at 21 weeks of age and 39% fewer at 34 weeks of age. Microscopically, control mice had increased numbers of foci of altered hepatocytes, particularly the basophilic subtype, as well as more, and malignant, liver neoplasms than did the Gpat1\n                    <jats:sup>-\/-<\/jats:sup>\n                    mice. At 21 weeks of age, 50% (4\/8) of control mice (50%) had hepatocellular adenomas with an average multiplicity (tumors per tumor-bearing-animal) of 4.3, while none occurred in 8 Gpat1\n                    <jats:sup>-\/-<\/jats:sup>\n                    mice. At 34 weeks of age, all 15 control mice (100%) had hepatocellular adenomas with an average multiplicity of 5.2 compared to an incidence of 93% in Gpat1\n                    <jats:sup>-\/-<\/jats:sup>\n                    mice and multiplicity of 3.1. HCCs were observed in 13% of control mice and in only 6% of Gpat1\n                    <jats:sup>-\/-<\/jats:sup>\n                    mice. These data show that alterations in the formation of complex lipids catalyzed by Gpat1 reduce susceptibility to DEN-induced liver tumorigenesis.\n                  <\/jats:p>","DOI":"10.1177\/0192623311432298","type":"journal-article","created":{"date-parts":[[2012,1,4]],"date-time":"2012-01-04T02:35:54Z","timestamp":1325644554000},"page":"513-521","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":22,"title":["Mice Deficient in Glycerol-3-Phosphate Acyltransferase-1 Have a Reduced Susceptibility to Liver Cancer"],"prefix":"10.1177","volume":"40","author":[{"given":"Jessica M.","family":"Ellis","sequence":"first","affiliation":[{"name":"Department of Nutrition, University of North Carolina, Chapel Hill, North Carolina, USA"},{"name":"Department of Biological Chemistry, Center for Metabolism and Obesity Research, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David S.","family":"Paul","sequence":"additional","affiliation":[{"name":"Department of Nutrition, University of North Carolina, Chapel Hill, North Carolina, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael A.","family":"DePetrillo","sequence":"additional","affiliation":[{"name":"Department of Nutrition, University of North Carolina, Chapel Hill, North Carolina, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bhanu P.","family":"Singh","sequence":"additional","affiliation":[{"name":"National Toxicology Program, National Institute of Environmental Health and Sciences, Cellular and Molecular Pathology Branch, Research Triangle Park, North Carolina, USA"},{"name":"Dupont Haskell Global Centers for Health and Environmental Sciences, Newark, Delaware, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David E.","family":"Malarkey","sequence":"additional","affiliation":[{"name":"National Toxicology Program, National Institute of Environmental Health and Sciences, Cellular and Molecular Pathology Branch, Research Triangle Park, North Carolina, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosalind A.","family":"Coleman","sequence":"additional","affiliation":[{"name":"Department of Nutrition, University of North Carolina, Chapel Hill, North Carolina, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,1,3]]},"reference":[{"key":"bibr1-0192623311432298","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2005-1024"},{"key":"bibr2-0192623311432298","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2004.09.011"},{"key":"bibr3-0192623311432298","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0409722102"},{"key":"bibr4-0192623311432298","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0609140103"},{"key":"bibr5-0192623311432298","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-2275(20)38901-X"},{"key":"bibr6-0192623311432298","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M708151200"},{"key":"bibr7-0192623311432298","doi-asserted-by":"publisher","DOI":"10.1016\/S0163-7827(03)00051-1"},{"key":"bibr8-0192623311432298","doi-asserted-by":"publisher","DOI":"10.1007\/BF02533977"},{"key":"bibr9-0192623311432298","first-page":"69","volume":"331","author":"Diwan B.
