    Mouse brain organization revealed through direct genome-scale TF expression analysis (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-25
    Description: In the developing brain, transcription factors (TFs) direct the formation of a diverse array of neurons and glia. We identifed 1445 putative TFs in the mouse genome. We used in situ hybridization to map the expression of over 1000 of these TFs and TF-coregulator genes in the brains of developing mice. We found that 349 of these genes showed restricted expression patterns that were adequate to describe the anatomical organization of the brain. We provide a comprehensive inventory of murine TFs and their expression patterns in a searchable brain atlas database.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gray, Paul A -- Fu, Hui -- Luo, Ping -- Zhao, Qing -- Yu, Jing -- Ferrari, Annette -- Tenzen, Toyoaki -- Yuk, Dong-In -- Tsung, Eric F -- Cai, Zhaohui -- Alberta, John A -- Cheng, Le-Ping -- Liu, Yang -- Stenman, Jan M -- Valerius, M Todd -- Billings, Nathan -- Kim, Haesun A -- Greenberg, Michael E -- McMahon, Andrew P -- Rowitch, David H -- Stiles, Charles D -- Ma, Qiufu -- New York, N.Y. -- Science. 2004 Dec 24;306(5705):2255-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15618518" target="_blank"〉PubMed〈/a〉

    bHLH transcription factor Olig1 is required to repair demyelinated lesions in the CNS (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-12-18
    Description: Olig1 and Olig2 are closely related basic helix-loop-helix (bHLH) transcription factors that are expressed in myelinating oligodendrocytes and their progenitor cells in the developing central nervous system (CNS). Olig2 is necessary for the specification of oligodendrocytes, but the biological functions of Olig1 during oligodendrocyte lineage development are poorly understood. We show here that Olig1 function in mice is required not to develop the brain but to repair it. Specifically, we demonstrate a genetic requirement for Olig1 in repairing the types of lesions that occur in patients with multiple sclerosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arnett, Heather A -- Fancy, Stephen P J -- Alberta, John A -- Zhao, Chao -- Plant, Sheila R -- Kaing, Sovann -- Raine, Cedric S -- Rowitch, David H -- Franklin, Robin J M -- Stiles, Charles D -- 689/Multiple Sclerosis Society/United Kingdom -- NS08952/NS/NINDS NIH HHS/ -- NS11920/NS/NINDS NIH HHS/ -- NS4051/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2004 Dec 17;306(5704):2111-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15604411" target="_blank"〉PubMed〈/a〉

    Platelet-derived growth factor A chain is maternally encoded in Xenopus embryos (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-09-02
    Description: Transcription of zygotic genes does not occur in early Xenopus embryos until the mid-blastula transition, 6 to 7 hours after fertilization. Before this time, development is directed by maternal proteins and messenger RNAs stored within the egg. Two different forms of the A chain of platelet-derived growth factor (PDGF) are shown here to be encoded by maternal messenger RNAs. The two forms closely resemble human PDGF; however, the long form contains a hydrophobic region near the carboxyl terminus. The presence of PDGF messenger RNA in the embryo supports the idea that endogenous growth factors act at the earliest stages of embryogenesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mercola, M -- Melton, D A -- Stiles, C D -- New York, N.Y. -- Science. 1988 Sep 2;241(4870):1223-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3413486" target="_blank"〉PubMed〈/a〉

    Expression of the c-fos gene and of an fos-related gene is stimulated by platelet-derived growth factor (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-11-30
    Description: Complementary DNA clones of genes induced by platelet-derived growth factor (PDGF) in BALB/c-3T3 cells were isolated; one such clone contains a domain having nucleotide sequence homology with the third exon of c-fos. This nucleotide sequence homology is reflected in the predicted amino acid sequences of the gene products. Under low stringency conditions, the mouse v-fos gene cross-hybridizes with the PDGF-inducible complementary DNA clone. However, the messenger RNA transcripts of mouse c-fos and the new fos-related gene can be distinguished by gel electrophoresis and by S1 nuclease analysis. Expression of the authentic c-fos gene is induced by PDGF and superinduced by the combination of PDGF and cycloheximide.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cochran, B H -- Zullo, J -- Verma, I M -- Stiles, C D -- New York, N.Y. -- Science. 1984 Nov 30;226(4678):1080-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6093261" target="_blank"〉PubMed〈/a〉

    A cell-cycle constraint on the regulation of gene expression by platelet-derived growth factor (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-11-27
    Description: In density-arrested monolayer cultures of Balb/c 3T3 cells, platelet-derived growth factor (PDGF) stimulates expression of the c-myc and c-fos proto-oncogenes, as well as the functionally uncharacterized genes, JE, KC, and JB. These genes are not coordinately regulated. Under ordinary conditions, c-fos, JE, KC, and JB respond to PDGF only when the cells are in a state of G0 growth arrest at the time of PDGF addition. The c-myc gene is regulated in opposition to the other genes, responding best to PDGF in cycling cultures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rollins, B J -- Morrison, E D -- Stiles, C D -- CA 20042-09/CA/NCI NIH HHS/ -- GM 31489-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Nov 27;238(4831):1269-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Medicine, Dana-Farber Cancer Institute, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3685976" target="_blank"〉PubMed〈/a〉

    Notes: Summary A number of genes and cDNA sequences (including at least four oncogenes) are known to be expressed in a cell cycle-dependent manner, i.e. the levels of specific mRNAs vary with the phases of the cell cycle. In order to explore the significance of some of these sequences in the mitogenic response, we have investigated the expression of 8 cell cycle-dependent sequences (plus two control sequences, not expressed in a cell cycle-dependent manner) under a variety of conditions. These conditions included cells of different types, from different species, stimulated to proliferate by different mitogens. The genes (or sequences) studied included five cDNA clones whose sequences are preferentially expressed in early G1, i.e. two cDNA clones inducible by platelet-derived growth factor (JE-3 and KC-1), and three cDNA clones inducible by serum (2A9, 2F1, 4F1); and three oncogenes (c-myc, c-rasHa and p53) whose expression is known to be cell cycle-dependent. All of the tested genes, except 2A9, c-rasHa and the control genes, are expressed in a cell cycle-dependent manner in human peripheral blood mononuclear cells stimulated by phytohemagglutinin and in serum-stimulated mouse and Syrian hamster fibroblasts. The inducibility of these genes by different mitogens in cells of different types and from different species strongly suggests that these genes play a role in cell cycle progression. This conclusion is further supported by the known structural and functional similarities between cell-cycle dependent genes, oncogenes and genes coding for cell-cycle related molecules.

    Control of the Balb/c-3T3 cell cycle by nutrients and serum factors: Analysis using platelet-derived growth factor and platelet-poor plasma (1979)

    Notes: Much controversy regarding the relationship between nutrients and serum in regulation of cell growth can be reconciled by recognizing that serum contains multiple factors which regulate different events in the cell cycle. Serum was fractioned into a platelet-derived growth factor (PDGF), which induces cells to become competent to synthesize DNA, and plasma which allows competent cells to traverse G0/G1 and enter the S phase. Nutrients are not required for the cellular response to PDGF; however amino acids are required for plasma to promote the entry of PDGF-treated, competent cells into S phase. The nutrient independent, PDGF-modulated, growth regulatory event (competence) is located 12 hours prior to the G1/S phase boundary in quiescent, density-arrested Balb/c-3T3 cells. The nutrient dependent, plasma-modulated event is located six hours prior to the G1/S phase boundary and corresponds in time to a plasma dependent growth arrest point. Moreover, plasma controls the concentration of amino acids required for DNA synthesis. Infection of density-arrested Balb/c-3T3 cells with SV40 overrides both the nutrient independent and the nutrient dependent growth regulatory events.

    Notes: The platelet-derived growth factor (PDGF), which is found in serum but not in plasma, has been purified to homogeneity; it stimulates replication at a concentration of 10-10M. Brief treatment with PDGF causes densityinhibited Balb/c-3T3 cells to become competent to synthesize DNA; pituitary fibroblast growth factor (FGF) or precipitates of calcium phosphate also induce competence. Continuous treatment with plasma allows competent, but not incompetent, cells to synthesize DNA. A critical component of plasma is somatomedin, a group of hormones with insulin-like activity; multiplication-stimulating activity (MSA) or insulin replace plasma somatomedin in promoting DNA synthesis.We have studied the molecular correlates of competence and the role of SV40 gene A products in regulating DNA synthesis. Treatment of quiescent cells with pure PDGF or FGF causes the preferential synthesis of five cytoplasmic proteins (approximate molecular weight 29,000, 35,000, 45,000, 60,000, and 72,000 detected by SDS-PAGE under reducing conditions). Two of these competence-associated proteins (29,000 and 35,000 daltons) are found within 40 min of PDGF addition; they are not induced by plasma, insulin, or epidermal growth factor (EGF), PDGF, FGF, or calcium phosphate induce an ultrastructure change within the centriole of 3T3 cells; this ultrastructural modification of the centriole is detectable by immunofluorescence within 2 h of PDGF treatment. Plasma, EGF, or MSA do not modify the centriole. SV40 induces replicative DNA synthesis in growth-arrested 3T3 cells but does not cause this alteration in centriole structure.Gene A variants of SV40, including a mutant with temperature-sensitive (ts) T-antigen (ts A209), a deletion in t-antigen (dl 884), and several ts A209 strains containing t-antigen deletions were used to induce DNA synthesis in Balb/c-3T3 cells. Like wild type SV40, all strains induced DNA synthesis equally well under permissive or nonpermissive conditions. Addition of PDGF or plasma had little effect on SV40-induced DNA synthesis. Thus, the viral function that induces replicative DNA synthesis in Balb/c-3T3 cells is not t and is not temperature sensitive. This SV40 gene function overrides the cellular requirement for hormonal growth factors. It does not induce transient centriole deciliation, a hormonally regulated event.
