    Inhibition of experimental liver cirrhosis in mice by telomerase gene delivery (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-02-26
    Description: Accelerated telomere loss has been proposed to be a factor leading to end-stage organ failure in chronic diseases of high cellular turnover such as liver cirrhosis. To test this hypothesis directly, telomerase-deficient mice, null for the essential telomerase RNA (mTR) gene, were subjected to genetic, surgical, and chemical ablation of the liver. Telomere dysfunction was associated with defects in liver regeneration and accelerated the development of liver cirrhosis in response to chronic liver injury. Adenoviral delivery of mTR into the livers of mTR(-/-) mice with short dysfunctional telomeres restored telomerase activity and telomere function, alleviated cirrhotic pathology, and improved liver function. These studies indicate that telomere dysfunction contributes to chronic diseases of continual cellular loss-replacement and encourage the evaluation of "telomerase therapy" for such diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rudolph, K L -- Chang, S -- Millard, M -- Schreiber-Agus, N -- DePinho, R A -- K08 AG001019/AG/NIA NIH HHS/ -- R01HD28317/HD/NICHD NIH HHS/ -- R01HD34880/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2000 Feb 18;287(5456):1253-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Adult Oncology, Medicine and Genetics, Dana-Farber Cancer Institute, 44 Binney Street (M413), and Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10678830" target="_blank"〉PubMed〈/a〉

    Connecting chromosomes, crisis, and cancer (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-07-27
    Description: Cancer is a disease of impaired genome stability. The molecular forces that maintain genome integrity and sense altered chromosome structure are invariably subverted in cancer cells. Here, we explore the contrasting contributions of telomeres in the initiation and suppression of cancer and review the evidence supporting a role for telomere dysfunction as a mechanism driving the radical chromosomal aberrations that typify cancer genomes. Recent work suggests that passage of cells through crisis in the setting of deactivated DNA damage checkpoints provides a mutational mechanism that can generate the diverse genetic alterations required for cancer initiation. A greater understanding of telomere-induced crisis and the cell's crisis management mechanisms should guide the rational development of new therapeutics for cancer and other disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maser, Richard S -- DePinho, Ronald A -- New York, N.Y. -- Science. 2002 Jul 26;297(5581):565-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Adult Oncology, Dana-Farber Cancer Institute, Harvard Medical School, 44 Binney Street, M413, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12142527" target="_blank"〉PubMed〈/a〉

    Lkb1 regulates quiescence and metabolic homeostasis of haematopoietic stem cells (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-12-03
    Description: The capacity to fine-tune cellular bioenergetics with the demands of stem-cell maintenance and regeneration is central to normal development and ageing, and to organismal survival during periods of acute stress. How energy metabolism and stem-cell homeostatic processes are coordinated is not well understood. Lkb1 acts as an evolutionarily conserved regulator of cellular energy metabolism in eukaryotic cells and functions as the major upstream kinase to phosphorylate AMP-activated protein kinase (AMPK) and 12 other AMPK-related kinases. Whether Lkb1 regulates stem-cell maintenance remains unknown. Here we show that Lkb1 has an essential role in haematopoietic stem cell (HSC) homeostasis. We demonstrate that ablation of Lkb1 in adult mice results in severe pancytopenia and subsequent lethality. Loss of Lkb1 leads to impaired survival and escape from quiescence of HSCs, resulting in exhaustion of the HSC pool and a marked reduction of HSC repopulating potential in vivo. Lkb1 deletion has an impact on cell proliferation in HSCs, but not on more committed compartments, pointing to context-specific functions for Lkb1 in haematopoiesis. The adverse impact of Lkb1 deletion on haematopoiesis was predominantly cell-autonomous and mTOR complex 1 (mTORC1)-independent, and involves multiple mechanisms converging on mitochondrial apoptosis and possibly downregulation of PGC-1 coactivators and their transcriptional network, which have critical roles in mitochondrial biogenesis and function. Thus, Lkb1 serves as an essential regulator of HSCs and haematopoiesis, and more generally, points to the critical importance of coupling energy metabolism and stem-cell homeostasis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3058342/" 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/PMC3058342/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gan, Boyi -- Hu, Jian -- Jiang, Shan -- Liu, Yingchun -- Sahin, Ergun -- Zhuang, Li -- Fletcher-Sananikone, Eliot -- Colla, Simona -- Wang, Y Alan -- Chin, Lynda -- Depinho, Ronald A -- 01CA141508/CA/NCI NIH HHS/ -- R21 CA135057/CA/NCI NIH HHS/ -- R21 CA135057-01/CA/NCI NIH HHS/ -- R21CA135057/CA/NCI NIH HHS/ -- U01 CA141508/CA/NCI NIH HHS/ -- U01 CA141508-01/CA/NCI NIH HHS/ -- England -- Nature. 2010 Dec 2;468(7324):701-4. doi: 10.1038/nature09595.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Belfer Institute for Applied Cancer Science, Dana-Farber Cancer Institute, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21124456" target="_blank"〉PubMed〈/a〉

    p53 and Pten control neural and glioma stem/progenitor cell renewal and differentiation (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-10-25
    Description: Glioblastoma (GBM) is a highly lethal brain tumour presenting as one of two subtypes with distinct clinical histories and molecular profiles. The primary GBM subtype presents acutely as a high-grade disease that typically harbours mutations in EGFR, PTEN and INK4A/ARF (also known as CDKN2A), and the secondary GBM subtype evolves from the slow progression of a low-grade disease that classically possesses PDGF and TP53 events. Here we show that concomitant central nervous system (CNS)-specific deletion of p53 and Pten in the mouse CNS generates a penetrant acute-onset high-grade malignant glioma phenotype with notable clinical, pathological and molecular resemblance to primary GBM in humans. This genetic observation prompted TP53 and PTEN mutational analysis in human primary GBM, demonstrating unexpectedly frequent inactivating mutations of TP53 as well as the expected PTEN mutations. Integrated transcriptomic profiling, in silico promoter analysis and functional studies of murine neural stem cells (NSCs) established that dual, but not singular, inactivation of p53 and Pten promotes an undifferentiated state with high renewal potential and drives increased Myc protein levels and its associated signature. Functional studies validated increased Myc activity as a potent contributor to the impaired differentiation and enhanced renewal of NSCs doubly null for p53 and Pten (p53(-/-) Pten(-/-)) as well as tumour neurospheres (TNSs) derived from this model. Myc also serves to maintain robust tumorigenic potential of p53(-/-) Pten(-/-) TNSs. These murine modelling studies, together with confirmatory transcriptomic/promoter studies in human primary GBM, validate a pathogenetic role of a common tumour suppressor mutation profile in human primary GBM and establish Myc as an important target for cooperative actions of p53 and Pten in the regulation of normal and malignant stem/progenitor cell differentiation, self-renewal and tumorigenic potential.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4051433/" 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/PMC4051433/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zheng, Hongwu -- Ying, Haoqiang -- Yan, Haiyan -- Kimmelman, Alec C -- Hiller, David J -- Chen, An-Jou -- Perry, Samuel R -- Tonon, Giovanni -- Chu, Gerald C -- Ding, Zhihu -- Stommel, Jayne M -- Dunn, Katherine L -- Wiedemeyer, Ruprecht -- You, Mingjian J -- Brennan, Cameron -- Wang, Y Alan -- Ligon, Keith L -- Wong, Wing H -- Chin, Lynda -- DePinho, Ronald A -- 5P01CA95616/CA/NCI NIH HHS/ -- P01 CA095616/CA/NCI NIH HHS/ -- P01 CA095616-01A19003/CA/NCI NIH HHS/ -- R01 CA099041/CA/NCI NIH HHS/ -- R01 CA099041-05/CA/NCI NIH HHS/ -- R01CA99041/CA/NCI NIH HHS/ -- U01 CA84313/CA/NCI NIH HHS/ -- England -- Nature. 2008 Oct 23;455(7216):1129-33. doi: 10.1038/nature07443.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical Oncology, Dana-Farber Cancer Institute and Harvard Medical School, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18948956" target="_blank"〉PubMed〈/a〉

    HDAC2 negatively regulates memory formation and synaptic plasticity (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-05-09
    Description: Chromatin modifications, especially histone-tail acetylation, have been implicated in memory formation. Increased histone-tail acetylation induced by inhibitors of histone deacetylases (HDACis) facilitates learning and memory in wild-type mice as well as in mouse models of neurodegeneration. Harnessing the therapeutic potential of HDACis requires knowledge of the specific HDAC family member(s) linked to cognitive enhancement. Here we show that neuron-specific overexpression of HDAC2, but not that of HDAC1, decreased dendritic spine density, synapse number, synaptic plasticity and memory formation. Conversely, Hdac2 deficiency resulted in increased synapse number and memory facilitation, similar to chronic treatment with HDACis in mice. Notably, reduced synapse number and learning impairment of HDAC2-overexpressing mice were ameliorated by chronic treatment with HDACis. Correspondingly, treatment with HDACis failed to further facilitate memory formation in Hdac2-deficient mice. Furthermore, analysis of promoter occupancy revealed an association of HDAC2 with the promoters of genes implicated in synaptic plasticity and memory formation. Taken together, our results suggest that HDAC2 functions in modulating synaptic plasticity and long-lasting changes of neural circuits, which in turn negatively regulates learning and memory. These observations encourage the development and testing of HDAC2-selective inhibitors for human diseases associated with memory impairment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3498958/" 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/PMC3498958/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guan, Ji-Song -- Haggarty, Stephen J -- Giacometti, Emanuela -- Dannenberg, Jan-Hermen -- Joseph, Nadine -- Gao, Jun -- Nieland, Thomas J F -- Zhou, Ying -- Wang, Xinyu -- Mazitschek, Ralph -- Bradner, James E -- DePinho, Ronald A -- Jaenisch, Rudolf -- Tsai, Li-Huei -- R01 DA028301/DA/NIDA NIH HHS/ -- R01 DA028301-02/DA/NIDA NIH HHS/ -- R01 NS051874/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 May 7;459(7243):55-60. doi: 10.1038/nature07925.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Picower Institute for Learning and Memory, Department of Brain and Cognitive Sciences.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19424149" target="_blank"〉PubMed〈/a〉

    Linking functional decline of telomeres, mitochondria and stem cells during ageing (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-03-26
    Description: The study of human genetic disorders and mutant mouse models has provided evidence that genome maintenance mechanisms, DNA damage signalling and metabolic regulation cooperate to drive the ageing process. In particular, age-associated telomere damage, diminution of telomere 'capping' function and associated p53 activation have emerged as prime instigators of a functional decline of tissue stem cells and of mitochondrial dysfunction that adversely affect renewal and bioenergetic support in diverse tissues. Constructing a model of how telomeres, stem cells and mitochondria interact with key molecules governing genome integrity, 'stemness' and metabolism provides a framework for how diverse factors contribute to ageing and age-related disorders.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3733214/" 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/PMC3733214/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sahin, Ergun -- Depinho, Ronald A -- R01 CA084628/CA/NCI NIH HHS/ -- R01CA84628/CA/NCI NIH HHS/ -- U01 CA84313/CA/NCI NIH HHS/ -- England -- Nature. 2010 Mar 25;464(7288):520-8. doi: 10.1038/nature08982.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Belfer Institute for Applied Cancer Science, Department of Medical Oncology, Dana-Farber Cancer Institute, Harvard Medical School, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20336134" target="_blank"〉PubMed〈/a〉

    Coactivation of receptor tyrosine kinases affects the response of tumor cells to targeted therapies (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-09-18
    Description: Targeted therapies that inhibit receptor tyrosine kinases (RTKs) and the downstream phosphatidylinositol 3-kinase (PI3K) signaling pathway have shown promising anticancer activity, but their efficacy in the brain tumor glioblastoma multiforme (GBM) and other solid tumors has been modest. We hypothesized that multiple RTKs are coactivated in these tumors and that redundant inputs drive and maintain downstream signaling, thereby limiting the efficacy of therapies targeting single RTKs. Tumor cell lines, xenotransplants, and primary tumors indeed show multiple concomitantly activated RTKs. Combinations of RTK inhibitors and/or RNA interference, but not single agents, decreased signaling, cell survival, and anchorage-independent growth even in glioma cells deficient in PTEN, a frequently inactivated inhibitor of PI3K. Thus, effective GBM therapy may require combined regimens targeting multiple RTKs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stommel, Jayne M -- Kimmelman, Alec C -- Ying, Haoqiang -- Nabioullin, Roustem -- Ponugoti, Aditya H -- Wiedemeyer, Ruprecht -- Stegh, Alexander H -- Bradner, James E -- Ligon, Keith L -- Brennan, Cameron -- Chin, Lynda -- DePinho, Ronald A -- 5P01CA95616/CA/NCI NIH HHS/ -- R01CA99041/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2007 Oct 12;318(5848):287-90.

    The kinase LKB1 mediates glucose homeostasis in liver and therapeutic effects of metformin (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-11-26
    Description: The Peutz-Jegher syndrome tumor-suppressor gene encodes a protein-threonine kinase, LKB1, which phosphorylates and activates AMPK [adenosine monophosphate (AMP)-activated protein kinase]. The deletion of LKB1 in the liver of adult mice resulted in a nearly complete loss of AMPK activity. Loss of LKB1 function resulted in hyperglycemia with increased gluconeogenic and lipogenic gene expression. In LKB1-deficient livers, TORC2, a transcriptional coactivator of CREB (cAMP response element-binding protein), was dephosphorylated and entered the nucleus, driving the expression of peroxisome proliferator-activated receptor-gamma coactivator 1alpha (PGC-1alpha), which in turn drives gluconeogenesis. Adenoviral small hairpin RNA (shRNA) for TORC2 reduced PGC-1alpha expression and normalized blood glucose levels in mice with deleted liver LKB1, indicating that TORC2 is a critical target of LKB1/AMPK signals in the regulation of gluconeogenesis. Finally, we show that metformin, one of the most widely prescribed type 2 diabetes therapeutics, requires LKB1 in the liver to lower blood glucose levels.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3074427/" 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/PMC3074427/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shaw, Reuben J -- Lamia, Katja A -- Vasquez, Debbie -- Koo, Seung-Hoi -- Bardeesy, Nabeel -- Depinho, Ronald A -- Montminy, Marc -- Cantley, Lewis C -- CA84313/CA/NCI NIH HHS/ -- GM056203/GM/NIGMS NIH HHS/ -- GM37828/GM/NIGMS NIH HHS/ -- R01 GM056203/GM/NIGMS NIH HHS/ -- R01 GM056203-09/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2005 Dec 9;310(5754):1642-6.
