Description:
Lhx3 and Lhx4 (Gsh4), two closely related LIM homeobox genes, determine formation of the pituitary gland in mice. Rathke's pouch is formed in two steps-first as a rudiment and later as a definitive pouch. Lhx3 and Lhx4 have redundant control over formation of the definitive pouch. Lhx3 controls a subsequent step of pituitary fate commitment. Thereafter, Lhx3 and Lhx4 together regulate proliferation and differentiation of pituitary-specific cell lineages. Thus, Lhx3 and Lhx4 dictate pituitary organ identity by controlling developmental decisions at multiple stages of organogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sheng, H Z -- Moriyama, K -- Yamashita, T -- Li, H -- Potter, S S -- Mahon, K A -- Westphal, H -- New York, N.Y. -- Science. 1997 Dec 5;278(5344):1809-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Mammalian Genes and Development, National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9388186" target="_blank"〉PubMed〈/a〉
