Description:
Songbirds represent an important model organism for elucidating molecular mechanisms that link genes with complex behaviors, in part because they have discrete vocal learning circuits that have parallels with those that mediate human speech. We found that ~10% of the genes in the avian genome were regulated by singing, and we found a striking regional diversity of both basal and singing-induced programs in the four key song nuclei of the zebra finch, a vocal learning songbird. The region-enriched patterns were a result of distinct combinations of region-enriched transcription factors (TFs), their binding motifs, and presinging acetylation of histone 3 at lysine 27 (H3K27ac) enhancer activity in the regulatory regions of the associated genes. RNA interference manipulations validated the role of the calcium-response transcription factor (CaRF) in regulating genes preferentially expressed in specific song nuclei in response to singing. Thus, differential combinatorial binding of a small group of activity-regulated TFs and predefined epigenetic enhancer activity influences the anatomical diversity of behaviorally regulated gene networks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4359888/" 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/PMC4359888/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitney, Osceola -- Pfenning, Andreas R -- Howard, Jason T -- Blatti, Charles A -- Liu, Fang -- Ward, James M -- Wang, Rui -- Audet, Jean-Nicoles -- Kellis, Manolis -- Mukherjee, Sayan -- Sinha, Saurabh -- Hartemink, Alexander J -- West, Anne E -- Jarvis, Erich D -- 5T32MH018882-18/MH/NIMH NIH HHS/ -- R01 DC007218/DC/NIDCD NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01DC007218/DC/NIDCD NIH HHS/ -- R21 NS084336/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Dec 12;346(6215):1256780. doi: 10.1126/science.1256780.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Howard Hughes Medical Institute, and Duke University Medical Center, Durham, NC 27710, USA. owhitney@gmail.com apfenning@csail.mit.edu west@neuro.duke.edu jarvis@neuro.duke.edu. ; Department of Neurobiology, Howard Hughes Medical Institute, and Duke University Medical Center, Durham, NC 27710, USA.
