Using targeted deletion of the Gpbar1 gene in mice, we show that the gene plays a critical role in the maintenance of bile lipid homoeostasis. Mice lacking Gpbar1 expression were viable, developed normally and did not show significant difference in the levels of cholesterol, BAs or any other bile constituents. However, they did not form cholesterol gallstones when fed a cholic acid-containing high-fat diet, and liver-specific gene expression indicated that Gpbar1-deficient mice have altered feedback regulation of BA synthesis. These results suggest that Gpbar1 plays a critical role in the formation of gallstones, possibly via a regulatory mechanism involving the cholesterol 7\u03b1-hydroxylase pathway.<\/jats:p>","DOI":"10.1042\/bj20060537","type":"journal-article","created":{"date-parts":[[2006,8,31]],"date-time":"2006-08-31T10:45:57Z","timestamp":1157021157000},"page":"423-430","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":256,"title":["Targeted deletion of Gpbar1 protects mice from cholesterol gallstone formation"],"prefix":"10.1042","volume":"398","author":[{"given":"Galya","family":"Vassileva","sequence":"first","affiliation":[{"name":"Department of Discovery Technologies, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrei","family":"Golovko","sequence":"additional","affiliation":[{"name":"Department of Discovery Technologies, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa","family":"Markowitz","sequence":"additional","affiliation":[{"name":"Department of Discovery Technologies, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan\u00a0J.","family":"Abbondanzo","sequence":"additional","affiliation":[{"name":"Department of Discovery Technologies, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming","family":"Zeng","sequence":"additional","affiliation":[{"name":"Department of Discovery Technologies, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shijun","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Discovery Technologies, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lizbeth","family":"Hoos","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular\/Metabolic Diseases, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Glen","family":"Tetzloff","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular\/Metabolic Diseases, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diane","family":"Levitan","sequence":"additional","affiliation":[{"name":"Department of Discovery Technologies, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas\u00a0J.","family":"Murgolo","sequence":"additional","affiliation":[{"name":"Department of Discovery Technologies, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin","family":"Keane","sequence":"additional","affiliation":[{"name":"Department of Drug Safety and Metabolism, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"Jr","given":"Harry\u00a0R.","family":"Davis","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular\/Metabolic Diseases, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Hedrick","sequence":"additional","affiliation":[{"name":"Department of Discovery Technologies, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric\u00a0L.","family":"Gustafson","sequence":"additional","affiliation":[{"name":"Department of Discovery Technologies, Schering-Plough Research Institute, Kenilworth, NJ 07033, U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2006,8,29]]},"reference":[{"key":"2021112213395750300_B1","doi-asserted-by":"crossref","first-page":"G349","DOI":"10.1152\/ajpgi.00417.2002","article-title":"Bile acid regulation of hepatic physiology: III.
