    Description: The pyrimidine analog 5-bromodeoxyuridine (BUdR) competes with thymidine for incorporation into DNA. Substitution of BUdR for thymidine does not significantly affect cell viability but does block cell differentiation in many different lineages. BUdR substitution in a mouse myoblast line blocked myogenic differentiation and extinguished the expression of the myogenic determination gene MyoD1. Forced expression of MyoD1 from a transfected expression vector in a BUdR-substituted myoblast overcame the block to differentiation imposed by BUdR. Activation of BUdR-substituted muscle structural genes and apparently normal differentiation were observed in transfected myoblasts. This shows that BUdR blocks myogenesis at the level of a myogenic regulatory gene, possibly MyoD1, not by directly inhibiting the activation of muscle structural genes. It is consistent with the idea that BUdR selectively blocks a class of regulatory genes, each member of which is important for the development of a different cell lineage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tapscott, S J -- Lassar, A B -- Davis, R L -- Weintraub, H -- New York, N.Y. -- Science. 1989 Aug 4;245(4917):532-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Fred Hutchinson Cancer Research Center, Seattle, WA 98104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2547249" target="_blank"〉PubMed〈/a〉

    Description: Expression of a complementary DNA (cDNA) encoding the mouse MyoD1 protein in a variety of fibroblast and adipoblast cell lines converts them to myogenic cells. Polyclonal antisera to fusion proteins containing the MyoD1 sequence show that MyoD1 is a phosphoprotein present in the nuclei of proliferating myoblasts and differentiated myotubes but not expressed in 10T1/2 fibroblasts or other nonmuscle cell types. Functional domains of the MyoD1 protein were analyzed by site-directed deletional mutagenesis of the MyoD1 cDNA. Deletion of a highly basic region (residues 102 to 135) interferes with both nuclear localization and induction of myogenesis. Deletion of a short region (residues 143 to 162) that is similar to a conserved region in the c-Myc family of proteins eliminates the ability of the MyoD1 protein to initiate myogenesis but does not alter nuclear localization. Deletions of regions spanning the remainder of MyoD1 did not affect nuclear localization and did not inhibit myogenesis. Furthermore, expression of only 68 amino acids of MyoD1, containing the basic and the Myc similarity domains, is sufficient to activate myogenesis in stably transfected 10T1/2 cells. Genetic analysis maps the MyoD1 gene to mouse chromosome 7 and human chromosome 11.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tapscott, S J -- Davis, R L -- Thayer, M J -- Cheng, P F -- Weintraub, H -- Lassar, A B -- New York, N.Y. -- Science. 1988 Oct 21;242(4877):405-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Fred Hutchinson Cancer Research Center, Seattle, WA 98104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3175662" target="_blank"〉PubMed〈/a〉

    Description: Centrioles are ancient organelles that build centrosomes, the major microtubule-organizing centers of animal cells. Extra centrosomes are a common feature of cancer cells. To investigate the importance of centrosomes in the proliferation of normal and cancer cells, we developed centrinone, a reversible inhibitor of Polo-like kinase 4 (Plk4), a serine-threonine protein kinase that initiates centriole assembly. Centrinone treatment caused centrosome depletion in human and other vertebrate cells. Centrosome loss irreversibly arrested normal cells in a senescence-like G1 state by a p53-dependent mechanism that was independent of DNA damage, stress, Hippo signaling, extended mitotic duration, or segregation errors. In contrast, cancer cell lines with normal or amplified centrosome numbers could proliferate indefinitely after centrosome loss. Upon centrinone washout, each cancer cell line returned to an intrinsic centrosome number "set point." Thus, cells with cancer-associated mutations fundamentally differ from normal cells in their response to centrosome loss.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4764081/" 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/PMC4764081/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wong, Yao Liang -- Anzola, John V -- Davis, Robert L -- Yoon, Michelle -- Motamedi, Amir -- Kroll, Ashley -- Seo, Chanmee P -- Hsia, Judy E -- Kim, Sun K -- Mitchell, Jennifer W -- Mitchell, Brian J -- Desai, Arshad -- Gahman, Timothy C -- Shiau, Andrew K -- Oegema, Karen -- GM074207/GM/NIGMS NIH HHS/ -- GM089970/GM/NIGMS NIH HHS/ -- GM103403/GM/NIGMS NIH HHS/ -- R01 GM089970/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Jun 5;348(6239):1155-60. doi: 10.1126/science.aaa5111.

    Description: Although it is generally accepted that cellular differentiation requires changes to transcriptional networks, dynamic regulation of promoters and enhancers at specific sets of genes has not been previously studied en masse. Exploiting the fact that active promoters and enhancers are transcribed, we simultaneously measured their activity in 19 human and 14 mouse time courses covering a wide range of cell types and biological stimuli. Enhancer RNAs, then messenger RNAs encoding transcription factors, dominated the earliest responses. Binding sites for key lineage transcription factors were simultaneously overrepresented in enhancers and promoters active in each cellular system. Our data support a highly generalizable model in which enhancer transcription is the earliest event in successive waves of transcriptional change during cellular differentiation or activation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4681433/" 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/PMC4681433/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arner, Erik -- Daub, Carsten O -- Vitting-Seerup, Kristoffer -- Andersson, Robin -- Lilje, Berit -- Drablos, Finn -- Lennartsson, Andreas -- Ronnerblad, Michelle -- Hrydziuszko, Olga -- Vitezic, Morana -- Freeman, Tom C -- Alhendi, Ahmad M N -- Arner, Peter -- Axton, Richard -- Baillie, J Kenneth -- Beckhouse, Anthony -- Bodega, Beatrice -- Briggs, James -- Brombacher, Frank -- Davis, Margaret -- Detmar, Michael -- Ehrlund, Anna -- Endoh, Mitsuhiro -- Eslami, Afsaneh -- Fagiolini, Michela -- Fairbairn, Lynsey -- Faulkner, Geoffrey J -- Ferrai, Carmelo -- Fisher, Malcolm E -- Forrester, Lesley -- Goldowitz, Daniel -- Guler, Reto -- Ha, Thomas -- Hara, Mitsuko -- Herlyn, Meenhard -- Ikawa, Tomokatsu -- Kai, Chieko -- Kawamoto, Hiroshi -- Khachigian, Levon M -- Klinken, S Peter -- Kojima, Soichi -- Koseki, Haruhiko -- Klein, Sarah -- Mejhert, Niklas -- Miyaguchi, Ken -- Mizuno, Yosuke -- Morimoto, Mitsuru -- Morris, Kelly J -- Mummery, Christine -- Nakachi, Yutaka -- Ogishima, Soichi -- Okada-Hatakeyama, Mariko -- Okazaki, Yasushi -- Orlando, Valerio -- Ovchinnikov, Dmitry -- Passier, Robert -- Patrikakis, Margaret -- Pombo, Ana -- Qin, Xian-Yang -- Roy, Sugata -- Sato, Hiroki -- Savvi, Suzana -- Saxena, Alka -- Schwegmann, Anita -- Sugiyama, Daisuke -- Swoboda, Rolf -- Tanaka, Hiroshi -- Tomoiu, Andru -- Winteringham, Louise N -- Wolvetang, Ernst -- Yanagi-Mizuochi, Chiyo -- Yoneda, Misako -- Zabierowski, Susan -- Zhang, Peter -- Abugessaisa, Imad -- Bertin, Nicolas -- Diehl, Alexander D -- Fukuda, Shiro -- Furuno, Masaaki -- Harshbarger, Jayson -- Hasegawa, Akira -- Hori, Fumi -- Ishikawa-Kato, Sachi -- Ishizu, Yuri -- Itoh, Masayoshi -- Kawashima, Tsugumi -- Kojima, Miki -- Kondo, Naoto -- Lizio, Marina -- Meehan, Terrence F -- Mungall, Christopher J -- Murata, Mitsuyoshi -- Nishiyori-Sueki, Hiromi -- Sahin, Serkan -- Nagao-Sato, Sayaka -- Severin, Jessica -- de Hoon, Michiel J L -- Kawai, Jun -- Kasukawa, Takeya -- Lassmann, Timo -- Suzuki, Harukazu -- Kawaji, Hideya -- Summers, Kim M -- Wells, Christine -- FANTOM Consortium -- Hume, David A -- Forrest, Alistair R R -- Sandelin, Albin -- Carninci, Piero -- Hayashizaki, Yoshihide -- P30 CA010815/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2015 Feb 27;347(6225):1010-4. doi: 10.1126/science.1259418.

    Description: A human complementary DNA clone specific for the alpha-chain of the T-cell receptor and a panel of rodent X human somatic cell hybrids were used to map the alpha-chain gene to human chromosome 14 in a region proximal to the immunoglobulin heavy chain locus. Analysis by means of in situ hybridization of human metaphase chromosomes served to further localize the alpha-chain gene to region 14q11q12, which is consistently involved in translocations and inversions detectable in human T-cell leukemias and lymphomas. Thus, the locus for the alpha-chain T-cell receptor may participate in oncogene activation in T-cell tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Croce, C M -- Isobe, M -- Palumbo, A -- Puck, J -- Ming, J -- Tweardy, D -- Erikson, J -- Davis, M -- Rovera, G -- CA 10 815/CA/NCI NIH HHS/ -- CA16685/CA/NCI NIH HHS/ -- CA215875/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1985 Mar 1;227(4690):1044-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3919442" target="_blank"〉PubMed〈/a〉
