    Senescence induced by altered telomere state, not telomere loss (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-03-30
    Description: Primary human cells in culture invariably stop dividing and enter a state of growth arrest called replicative senescence. This transition is induced by programmed telomere shortening, but the underlying mechanisms are unclear. Here, we report that overexpression of TRF2, a telomeric DNA binding protein, increased the rate of telomere shortening in primary cells without accelerating senescence. TRF2 reduced the senescence setpoint, defined as telomere length at senescence, from 7 to 4 kilobases. TRF2 protected critically short telomeres from fusion and repressed chromosome-end fusions in presenescent cultures, which explains the ability of TRF2 to delay senescence. Thus, replicative senescence is induced by a change in the protected status of shortened telomeres rather than by a complete loss of telomeric DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karlseder, Jan -- Smogorzewska, Agata -- de Lange, Titia -- AG16643/AG/NIA NIH HHS/ -- CA76027/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2002 Mar 29;295(5564):2446-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Cell Biology and Genetics, The Rockefeller University, 1230 York Avenue, New York, NY 10021, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11923537" target="_blank"〉PubMed〈/a〉

    The Fanconi anemia pathway promotes replication-dependent DNA interstrand cross-link repair (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-12-08
    Description: Fanconi anemia is a human cancer predisposition syndrome caused by mutations in 13 Fanc genes. The disorder is characterized by genomic instability and cellular hypersensitivity to chemicals that generate DNA interstrand cross-links (ICLs). A central event in the activation of the Fanconi anemia pathway is the mono-ubiquitylation of the FANCI-FANCD2 complex, but how this complex confers ICL resistance remains enigmatic. Using a cell-free system, we showed that FANCI-FANCD2 is required for replication-coupled ICL repair in S phase. Removal of FANCD2 from extracts inhibits both nucleolytic incisions near the ICL and translesion DNA synthesis past the lesion. Reversal of these defects requires ubiquitylated FANCI-FANCD2. Our results show that multiple steps of the essential S-phase ICL repair mechanism fail when the Fanconi anemia pathway is compromised.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2909596/" 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/PMC2909596/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knipscheer, Puck -- Raschle, Markus -- Smogorzewska, Agata -- Enoiu, Milica -- Ho, The Vinh -- Scharer, Orlando D -- Elledge, Stephen J -- Walter, Johannes C -- GM62267/GM/NIGMS NIH HHS/ -- R01 GM062267/GM/NIGMS NIH HHS/ -- R01 GM062267-09/GM/NIGMS NIH HHS/ -- R37 GM044664/GM/NIGMS NIH HHS/ -- R37 GM044664-23/GM/NIGMS NIH HHS/ -- T32CA09216/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Dec 18;326(5960):1698-701. doi: 10.1126/science.1182372.

    Abraxas and RAP80 form a BRCA1 protein complex required for the DNA damage response (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-05-26
    Description: The BRCT repeats of the breast and ovarian cancer predisposition protein BRCA1 are essential for tumor suppression. Phosphopeptide affinity proteomic analysis identified a protein, Abraxas, that directly binds the BRCA1 BRCT repeats through a phospho-Ser-X-X-Phe motif. Abraxas binds BRCA1 to the mutual exclusion of BACH1 (BRCA1-associated C-terminal helicase) and CtIP (CtBP-interacting protein), forming a third type of BRCA1 complex. Abraxas recruits the ubiquitin-interacting motif (UIM)-containing protein RAP80 to BRCA1. Both Abraxas and RAP80 were required for DNA damage resistance, G(2)-M checkpoint control, and DNA repair. RAP80 was required for optimal accumulation of BRCA1 on damaged DNA (foci) in response to ionizing radiation, and the UIM domains alone were capable of foci formation. The RAP80-Abraxas complex may help recruit BRCA1 to DNA damage sites in part through recognition of ubiquitinated proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3573690/" 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/PMC3573690/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Bin -- Matsuoka, Shuhei -- Ballif, Bryan A -- Zhang, Dong -- Smogorzewska, Agata -- Gygi, Steven P -- Elledge, Stephen J -- 1KO1, CA116275-01/CA/NCI NIH HHS/ -- 1U19A1067751/PHS HHS/ -- T32CA09216/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2007 May 25;316(5828):1194-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Center for Genetics and Genomics, Brigham and Women's Hospital, Howard Hughes Medical 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/17525340" target="_blank"〉PubMed〈/a〉

    ATM and ATR substrate analysis reveals extensive protein networks responsive to DNA damage (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-05-26
    Description: Cellular responses to DNA damage are mediated by a number of protein kinases, including ATM (ataxia telangiectasia mutated) and ATR (ATM and Rad3-related). The outlines of the signal transduction portion of this pathway are known, but little is known about the physiological scope of the DNA damage response (DDR). We performed a large-scale proteomic analysis of proteins phosphorylated in response to DNA damage on consensus sites recognized by ATM and ATR and identified more than 900 regulated phosphorylation sites encompassing over 700 proteins. Functional analysis of a subset of this data set indicated that this list is highly enriched for proteins involved in the DDR. This set of proteins is highly interconnected, and we identified a large number of protein modules and networks not previously linked to the DDR. This database paints a much broader landscape for the DDR than was previously appreciated and opens new avenues of investigation into the responses to DNA damage in mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsuoka, Shuhei -- Ballif, Bryan A -- Smogorzewska, Agata -- McDonald, E Robert 3rd -- Hurov, Kristen E -- Luo, Ji -- Bakalarski, Corey E -- Zhao, Zhenming -- Solimini, Nicole -- Lerenthal, Yaniv -- Shiloh, Yosef -- Gygi, Steven P -- Elledge, Stephen J -- 1U19A1067751/PHS HHS/ -- New York, N.Y. -- Science. 2007 May 25;316(5828):1160-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics and Center for Genetics and Genomics, Brigham and Women's Hospital, Howard Hughes Medical 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/17525332" target="_blank"〉PubMed〈/a〉

    Cancer proliferation gene discovery through functional genomics (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-02-02
    Description: Retroviral short hairpin RNA (shRNA)-mediated genetic screens in mammalian cells are powerful tools for discovering loss-of-function phenotypes. We describe a highly parallel multiplex methodology for screening large pools of shRNAs using half-hairpin barcodes for microarray deconvolution. We carried out dropout screens for shRNAs that affect cell proliferation and viability in cancer cells and normal cells. We identified many shRNAs to be antiproliferative that target core cellular processes, such as the cell cycle and protein translation, in all cells examined. Moreover, we identified genes that are selectively required for proliferation and survival in different cell lines. Our platform enables rapid and cost-effective genome-wide screens to identify cancer proliferation and survival genes for target discovery. Such efforts are complementary to the Cancer Genome Atlas and provide an alternative functional view of cancer cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2981870/" 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/PMC2981870/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schlabach, Michael R -- Luo, Ji -- Solimini, Nicole L -- Hu, Guang -- Xu, Qikai -- Li, Mamie Z -- Zhao, Zhenming -- Smogorzewska, Agata -- Sowa, Mathew E -- Ang, Xiaolu L -- Westbrook, Thomas F -- Liang, Anthony C -- Chang, Kenneth -- Hackett, Jennifer A -- Harper, J Wade -- Hannon, Gregory J -- Elledge, Stephen J -- F31 NS054507-01/NS/NINDS NIH HHS/ -- P01 CA013106/CA/NCI NIH HHS/ -- P01 CA013106-36/CA/NCI NIH HHS/ -- P01 CA013106-37/CA/NCI NIH HHS/ -- R01 AG011085/AG/NIA NIH HHS/ -- T32CA09216/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Feb 1;319(5863):620-4. doi: 10.1126/science.1149200.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Genetics, Center for Genetics and Genomics, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18239126" target="_blank"〉PubMed〈/a〉

    Structure of the FANCI-FANCD2 complex: insights into the Fanconi anemia DNA repair pathway (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2011-07-19
    Description: Fanconi anemia is a cancer predisposition syndrome caused by defects in the repair of DNA interstrand cross-links (ICLs). Central to this pathway is the Fanconi anemia I-Fanconi anemia D2 (FANCI-FANCD2) (ID) complex, which is activated by DNA damage-induced phosphorylation and monoubiquitination. The 3.4 angstrom crystal structure of the ~300 kilodalton ID complex reveals that monoubiquitination and regulatory phosphorylation sites map to the I-D interface, suggesting that they occur on monomeric proteins or an opened-up complex and that they may serve to stabilize I-D heterodimerization. The 7.8 angstrom electron-density map of FANCI-DNA crystals and in vitro data show that each protein has binding sites for both single- and double-stranded DNA, suggesting that the ID complex recognizes DNA structures that result from the encounter of replication forks with an ICL.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3310437/" 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/PMC3310437/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Joo, Woo -- Xu, Guozhou -- Persky, Nicole S -- Smogorzewska, Agata -- Rudge, Derek G -- Buzovetsky, Olga -- Elledge, Stephen J -- Pavletich, Nikola P -- R01 GM044664/GM/NIGMS NIH HHS/ -- R01 GM044664-10/GM/NIGMS NIH HHS/ -- R37 GM044664/GM/NIGMS NIH HHS/ -- T32 CA009216/CA/NCI NIH HHS/ -- T32 CA009216-32/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Jul 15;333(6040):312-6. doi: 10.1126/science.1205805.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Structural Biology Program, Memorial Sloan-Kettering Cancer Center, New York, NY 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21764741" target="_blank"〉PubMed〈/a〉

    DNA repair. Mechanism of DNA interstrand cross-link processing by repair nuclease FAN1 (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-11-29
    Description: DNA interstrand cross-links (ICLs) are highly toxic lesions associated with cancer and degenerative diseases. ICLs can be repaired by the Fanconi anemia (FA) pathway and through FA-independent processes involving the FAN1 nuclease. In this work, FAN1-DNA crystal structures and biochemical data reveal that human FAN1 cleaves DNA successively at every third nucleotide. In vitro, this exonuclease mechanism allows FAN1 to excise an ICL from one strand through flanking incisions. DNA access requires a 5'-terminal phosphate anchor at a nick or a 1- or 2-nucleotide flap and is augmented by a 3' flap, suggesting that FAN1 action is coupled to DNA synthesis or recombination. FAN1's mechanism of ICL excision is well suited for processing other localized DNA adducts as well.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4285437/" 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/PMC4285437/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Renjing -- Persky, Nicole S -- Yoo, Barney -- Ouerfelli, Ouathek -- Smogorzewska, Agata -- Elledge, Stephen J -- Pavletich, Nikola P -- P30 CA008748/CA/NCI NIH HHS/ -- R01 HL120922/HL/NHLBI NIH HHS/ -- R01HL120922/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2014 Nov 28;346(6213):1127-30. doi: 10.1126/science.1258973.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Structural Biology Program and Howard Hughes Medical Institute, Memorial Sloan Kettering Cancer Center, New York, NY 10065, USA. ; Molecular Pharmacology and Chemistry Program, Memorial Sloan Kettering Cancer Center, New York, NY 10065, USA. ; Laboratory of Genome Maintenance, The Rockefeller University, New York, NY 10065, USA. ; Department of Genetics and Howard Hughes Medical Institute, Harvard Medical School, Boston, MA 02115, USA.
