In this study, the 5 mouse strains were able to synthesize melatonin, but the basal levels as well as the diurnal variations were very different from one strain to another. CBA and C3H strains showed a clear-cut day-night rhythm of pineal melatonin concentration, with peak levels of 276 \u00b1 22 pg\/pineal in CBA and 135 \u00b1 12 pg\/pineal in C3H. In BALB\/c, the authors confirmed the presence of a very short melatonin peak (15 min) in the middle of the dark period. In C57BL\/6 and OF1 Swiss, a very small but significant peak was observed in the middle of the darkness. In the former, another small peak was also observed at light onset. Whether these very small peaks, which may be related to the deficience of N-acetyl transferase activity reported by others, have a physiological meaning remains to be determined.<\/jats:p>","DOI":"10.1177\/074873098129000228","type":"journal-article","created":{"date-parts":[[2004,5,27]],"date-time":"2004-05-27T09:25:01Z","timestamp":1085649901000},"page":"403-409","source":"Crossref","is-referenced-by-count":112,"title":["Daily Variations in Pineal Melatonin Concentrations in Inbred and Outbred Mice"],"prefix":"10.1177","volume":"13","author":[{"given":"Berthe","family":"Vivien-Roels","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9","family":"Malan","sequence":"additional","affiliation":[{"name":"UMR CNRS 7518, Neurobiologie des fonctions rythmiques et saisonni\u00e8res, Universit\u00e9 Louis Pasteur, 12, rue de l'Universit\u00e9, F-67000 Strasbourg, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie-Claire","family":"Rettori","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Delagrange","sequence":"additional","affiliation":[{"name":"Institut de Recherches Internationales Servier, Courbevoie, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Philippe","family":"Jeanniot","sequence":"additional","affiliation":[{"name":"Technologie SERVIER, Orl\u00e9ans, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"P\u00e9vet","sequence":"additional","affiliation":[{"name":"UMR CNRS 7518, Neurobiologie des fonctions rythmiques et saisonni\u00e8res, Universit\u00e9 Louis Pasteur, 12, rue de l'Universit\u00e9, F-67000 Strasbourg, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1998,10,1]]},"reference":[{"key":"atypb1","first-page":"489","volume":"17","author":"Carter-Dawson LD","year":"1978","journal-title":"Invest Ophtalmol Visual Sci"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-079X.1996.tb00249.x"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1016\/0006-8993(87)91505-8"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1126\/science.3941912"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-079X.1989.tb00667.x"},{"key":"atypb6","first-page":"289","volume-title":"Melatonin, Biosynthesis, Physiologi-cal Effects and Clinical Approaches","author":"Maestroni GJM and Conti A","year":"1993"},{"key":"atypb7","doi-asserted-by":"publisher","DOI":"10.1016\/0165-5728(86)90047-0"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1111\/j.1749-6632.1987.tb35747.x"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4615-1911-9_4"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4615-3756-4_15"},{"issue":"2","key":"atypb11","first-page":"2056","volume":"23","author":"Rosenboom PH","year":"1997","journal-title":"27th annual meeting, New Orleans Society for Neurosciences"},{"key":"atypb12","volume-title":"Comparative Endocrinology and Mammalian Reproductive Physiology","author":"Vivien-Roels B","year":"1998"},{"key":"atypb13","first-page":"85","volume":"106","author":"Vivien-Roels B","year":"1997","journal-title":"Cricetus cricetus"},{"key":"atypb14","doi-asserted-by":"publisher","DOI":"10.1530\/acta.0.1170093"}],"container-title":["Journal of Biological Rhythms"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/074873098129000228","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/074873098129000228","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T19:58:51Z","timestamp":1777492731000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/074873098129000228"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998,10]]},"references-count":14,"journal-issue":{"issue":"5","published-print":{"date-parts":[[1998,10]]}},"alternative-id":["10.1177\/074873098129000228"],"URL":"https:\/\/doi.org\/10.1177\/074873098129000228","relation":{},"ISSN":["0748-7304","1552-4531"],"issn-type":[{"value":"0748-7304","type":"print"},{"value":"1552-4531","type":"electronic"}],"subject":[],"published":{"date-parts":[[1998,10]]}}}
