Description:
Models of mammalian regulatory networks controlling gene expression have been inferred from genomic data but have largely not been validated. We present an unbiased strategy to systematically perturb candidate regulators and monitor cellular transcriptional responses. We applied this approach to derive regulatory networks that control the transcriptional response of mouse primary dendritic cells to pathogens. Our approach revealed the regulatory functions of 125 transcription factors, chromatin modifiers, and RNA binding proteins, which enabled the construction of a network model consisting of 24 core regulators and 76 fine-tuners that help to explain how pathogen-sensing pathways achieve specificity. This study establishes a broadly applicable, comprehensive, and unbiased approach to reveal the wiring and functions of a regulatory network controlling a major transcriptional response in primary mammalian cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2879337/" 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/PMC2879337/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Amit, Ido -- Garber, Manuel -- Chevrier, Nicolas -- Leite, Ana Paula -- Donner, Yoni -- Eisenhaure, Thomas -- Guttman, Mitchell -- Grenier, Jennifer K -- Li, Weibo -- Zuk, Or -- Schubert, Lisa A -- Birditt, Brian -- Shay, Tal -- Goren, Alon -- Zhang, Xiaolan -- Smith, Zachary -- Deering, Raquel -- McDonald, Rebecca C -- Cabili, Moran -- Bernstein, Bradley E -- Rinn, John L -- Meissner, Alex -- Root, David E -- Hacohen, Nir -- Regev, Aviv -- DP1 OD003958/OD/NIH HHS/ -- DP1 OD003958-01/OD/NIH HHS/ -- DP2 OD002230/OD/NIH HHS/ -- DP2 OD002230-01/OD/NIH HHS/ -- R21 AI071060/AI/NIAID NIH HHS/ -- R21 AI071060-01/AI/NIAID NIH HHS/ -- R21 AI71060/AI/NIAID NIH HHS/ -- S10 RR026688/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Oct 9;326(5950):257-63. doi: 10.1126/science.1179050.
