    Human-specific gain of function in a developmental enhancer (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-09-06
    Description: Changes in gene regulation are thought to have contributed to the evolution of human development. However, in vivo evidence for uniquely human developmental regulatory function has remained elusive. In transgenic mice, a conserved noncoding sequence (HACNS1) that evolved extremely rapidly in humans acted as an enhancer of gene expression that has gained a strong limb expression domain relative to the orthologous elements from chimpanzee and rhesus macaque. This gain of function was consistent across two developmental stages in the mouse and included the presumptive anterior wrist and proximal thumb. In vivo analyses with synthetic enhancers, in which human-specific substitutions were introduced into the chimpanzee enhancer sequence or reverted in the human enhancer to the ancestral state, indicated that 13 substitutions clustered in an 81-base pair module otherwise highly constrained among terrestrial vertebrates were sufficient to confer the human-specific limb expression domain.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2658639/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2658639/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Prabhakar, Shyam -- Visel, Axel -- Akiyama, Jennifer A -- Shoukry, Malak -- Lewis, Keith D -- Holt, Amy -- Plajzer-Frick, Ingrid -- Morrison, Harris -- Fitzpatrick, David R -- Afzal, Veena -- Pennacchio, Len A -- Rubin, Edward M -- Noonan, James P -- 1-F32-GM074367/GM/NIGMS NIH HHS/ -- F32 GM074367/GM/NIGMS NIH HHS/ -- F32 GM074367-02/GM/NIGMS NIH HHS/ -- HG003988/HG/NHGRI NIH HHS/ -- HL066681/HL/NHLBI NIH HHS/ -- MC_U127561093/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2008 Sep 5;321(5894):1346-50. doi: 10.1126/science.1159974.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genomics Division, Lawrence Berkeley National Laboratory, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18772437" target="_blank"〉PubMed〈/a〉

    Fine tuning of craniofacial morphology by distant-acting enhancers (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-10-26
    Description: The shape of the human face and skull is largely genetically determined. However, the genomic basis of craniofacial morphology is incompletely understood and hypothesized to involve protein-coding genes, as well as gene regulatory sequences. We used a combination of epigenomic profiling, in vivo characterization of candidate enhancer sequences in transgenic mice, and targeted deletion experiments to examine the role of distant-acting enhancers in craniofacial development. We identified complex regulatory landscapes consisting of enhancers that drive spatially complex developmental expression patterns. Analysis of mouse lines in which individual craniofacial enhancers had been deleted revealed significant alterations of craniofacial shape, demonstrating the functional importance of enhancers in defining face and skull morphology. These results demonstrate that enhancers are involved in craniofacial development and suggest that enhancer sequence variation contributes to the diversity of human facial morphology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3991470/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3991470/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Attanasio, Catia -- Nord, Alex S -- Zhu, Yiwen -- Blow, Matthew J -- Li, Zirong -- Liberton, Denise K -- Morrison, Harris -- Plajzer-Frick, Ingrid -- Holt, Amy -- Hosseini, Roya -- Phouanenavong, Sengthavy -- Akiyama, Jennifer A -- Shoukry, Malak -- Afzal, Veena -- Rubin, Edward M -- FitzPatrick, David R -- Ren, Bing -- Hallgrimsson, Benedikt -- Pennacchio, Len A -- Visel, Axel -- 1R01DE01963/DE/NIDCR NIH HHS/ -- 1R01DE021708/DE/NIDCR NIH HHS/ -- 1U01DE020054/DE/NIDCR NIH HHS/ -- F32 GM105202/GM/NIGMS NIH HHS/ -- MC_PC_U127561093/Medical Research Council/United Kingdom -- MC_U127561093/Medical Research Council/United Kingdom -- R01 DE019638/DE/NIDCR NIH HHS/ -- R01 DE021708/DE/NIDCR NIH HHS/ -- R01 HG003988/HG/NHGRI NIH HHS/ -- R01 HG003991/HG/NHGRI NIH HHS/ -- R01HG003988/HG/NHGRI NIH HHS/ -- R01HG003991/HG/NHGRI NIH HHS/ -- U01 DE020054/DE/NIDCR NIH HHS/ -- U01 DE020060/DE/NIDCR NIH HHS/ -- U01DE020060/DE/NIDCR NIH HHS/ -- U54 HG006997/HG/NHGRI NIH HHS/ -- U54HG006997/HG/NHGRI NIH HHS/ -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2013 Oct 25;342(6157):1241006. doi: 10.1126/science.1241006.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Lawrence Berkeley National Laboratory, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24159046" target="_blank"〉PubMed〈/a〉

    Hirschsprung disease is linked to defects in neural crest stem cell function (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-08-16
    Description: Genes associated with Hirschsprung disease, a failure to form enteric ganglia in the hindgut, were highly up-regulated in gut neural crest stem cells relative to whole-fetus RNA. One of these genes, the glial cell line-derived neurotrophic factor (GDNF) receptor Ret, was necessary for neural crest stem cell migration in the gut. GDNF promoted the migration of neural crest stem cells in culture but did not affect their survival or proliferation. Gene expression profiling, combined with reverse genetics and analyses of stem cell function, suggests that Hirschsprung disease is caused by defects in neural crest stem cell function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2614078/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2614078/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iwashita, Toshihide -- Kruger, Genevieve M -- Pardal, Ricardo -- Kiel, Mark J -- Morrison, Sean J -- CA46592/CA/NCI NIH HHS/ -- DK58771/DK/NIDDK NIH HHS/ -- NIH5P60-DK20572/DK/NIDDK NIH HHS/ -- P30 AR48310/AR/NIAMS NIH HHS/ -- P60-AR20557/AR/NIAMS NIH HHS/ -- R01 NS040750/NS/NINDS NIH HHS/ -- R01 NS040750-01/NS/NINDS NIH HHS/ -- R01 NS40750-01/NS/NINDS NIH HHS/ -- R21 HD40760-02/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2003 Aug 15;301(5635):972-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Internal Medicine, University of Michigan, Ann Arbor, MI 48109-0934, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12920301" target="_blank"〉PubMed〈/a〉
