Description:
The highly selective, enzyme-activated, irreversible inhibitor of L-ornithine decarboxylase, DL-alpha-difluoromethylornithine, suppresses the increase in uterine L-ornithine decarboxylase activity associated with early embryogenesis in the mouse and arrests embryonic development at that stage. Contragestational effects were confirmed in the rat and rabbit. An increase in L-ornithine decarboxylase activity that leads to a rapid increase in putrescine concentration appears to be essential during a critical period after implantation for continued mammalian embryonal growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fozard, J R -- Part, M L -- Prakash, N J -- Grove, J -- Schechter, P J -- Sjoerdsma, A -- Koch-Weser, J -- New York, N.Y. -- Science. 1980 May 2;208(4443):505-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6768132" target="_blank"〉PubMed〈/a〉
