FURTHER INSIGHTS INTO THE REGULATION OF THE FANCONI ANEMIA FANCD2 PROTEIN BY REBECCA ANNE BOISVERT A DISSERTATION SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY IN CELL AND MOLECULAR BIOLOGY UNIVERSITY OF RHODE ISLAND 2015 DOCTOR OF PHILOSOPHY DISSERTATION OF REBECCA ANNE BOISVERT APPROVED: Dissertation Committee: Major Professor Niall Howlett Paul Cohen Becky Sartini Nasser H. Zawia DEAN OF THE GRADUATE SCHOOL UNIVERSITY OF RHODE ISLAND 2015 ABSTRACT Fanconi anemia (FA) is a rare autosomal and X-linked recessive disorder, characterized by congenital abnormalities, pediatric bone marrow failure and cancer susceptibility. FA is caused by biallelic mutations in any one of 16 genes. The FA proteins function cooperatively in the FA-BRCA pathway to repair DNA interstrand crosslinks (ICLs). The monoubiquitination of FANCD2 and FANCI is a central step in the activation of the FA-BRCA pathway and is required for targeting these proteins to chromatin. -
Src Activation Plays an Important Key Role in Lymphomagenesis Induced by FGFR1 Fusion Kinases
Published OnlineFirst September 21, 2011; DOI: 10.1158/0008-5472.CAN-11-1109 Cancer Tumor and Stem Cell Biology Research Src Activation Plays an Important Key Role in Lymphomagenesis Induced by FGFR1 Fusion Kinases Mingqiang Ren, Haiyan Qin, Ruizhe Ren, Josephine Tidwell, and John K. Cowell Abstract Chromosomal translocations and activation of the fibroblast growth factor (FGF) receptor 1 (FGFR1) are a feature of stem cell leukemia–lymphoma syndrome (SCLL), an aggressive malignancy characterized by rapid transformation to acute myeloid leukemia and lymphoblastic lymphoma. It has been suggested that FGFR1 proteins lose their ability to recruit Src kinase, an important mediator of FGFR1 signaling, as a result of the translocations that delete the extended FGFR substrate-2 (FRS2) interacting domain that Src binds. In this study, we report evidence that refutes this hypothesis and reinforces the notion that Src is a critical mediator of signaling from the FGFR1 chimeric fusion genes generated by translocation in SCLL. Src was constitutively active in BaF3 cells expressing exogenous FGFR1 chimeric kinases cultured in vitro as well as in T-cell or B-cell lymphomas they induced in vivo. Residual components of the FRS2-binding site retained in chimeric kinases that were generated by translocation were sufficient to interact with FRS2 and activate Src. The Src kinase inhibitor dasatinib killed transformed BaF3 cells and other established murine leukemia cell lines expressing chimeric FGFR1 kinases, significantly extending the survival of mice with SCLL syndrome. Our results indicated that Src kinase is pathogenically activated in lymphomagenesis induced by FGFR1 fusion genes, implying that Src kinase inhibitors may offer a useful option to treatment of FGFR1-associated myeloproliferative/lymphoma disorders. -

Dysregulation of Rho Gtpases in the Apix/Arhgef6 Mouse Model of X
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2011 Dysregulation of Rho GTPases in the Pix/Arhgef6 mouse model of X-linked intellectual disability is paralleled by impaired structural and synaptic plasticity and cognitive deficits Ramakers, G J A ; Wolfer, D ; Rosenberger, G ; Kuchenbecker, K ; Kreienkamp, H J ; Prange-Kiel, J ; Rune, G ; Richter, K ; Langnaese, K ; Masneuf, S ; Bösl, M R ; Fischer, K D ; Krugers, H J ; Lipp, H P ; van Galen, E ; Kutsche, K Abstract: Mutations in the ARHGEF6 gene, encoding the guanine nucleotide exchange factor PIX/Cool- 2 for the Rho GTPases Rac1 and Cdc42, cause X-linked intellectual disability (ID) in humans. We show here that Pix/Arhgef6 is primarily expressed in neuropil regions of the hippocampus. To study the role of Pix/Arhgef6 in neuronal development and plasticity and gain insight into the pathogenic mechanisms underlying ID, we generated Pix/Arhgef6-deficient mice. Gross brain structure in these mice appeared to be normal; however, analysis of Golgi-Cox-stained pyramidal neurons revealed an increase in both dendritic length and spine density in the hippocampus, accompanied by an overall loss in spine synapses. Early-phase long-term potentiation was reduced and long-term depression was increased in the CA1 hippocampal area of Pix/Arhgef6-deficient animals. Knockout animals exhibited impaired spatial and complex learning and less behavioral control in mildly stressful situations, suggesting that this model mimics the human ID phenotype. The structural and electrophysiological alterations in the hippocampus were accompanied by a significant reduction in active Rac1 and Cdc42, but not RhoA. -
The Mental Retardation Protein PAK3 Contributes to Synapse Formation and Plasticity in Hippocampus
10816 • The Journal of Neuroscience, December 1, 2004 • 24(48):10816–10825 Development/Plasticity/Repair The Mental Retardation Protein PAK3 Contributes to Synapse Formation and Plasticity in Hippocampus Bernadett Boda, Stefano Alberi, Irina Nikonenko, Roxanne Node-Langlois, Pascal Jourdain, Marlyse Moosmayer, Lorena Parisi-Jourdain, and Dominique Muller Department of Basic Neuroscience, Centre Medical Universitaire, 1211 Geneva 4, Switzerland Mutations of the gene coding for PAK3 (p21-activated kinase 3) are associated with X-linked, nonsyndromic forms of mental retardation (MRX) in which the only distinctive clinical feature is the cognitive deficit. The mechanisms through which PAK3 mutation produces the mental handicap remain unclear, although an involvement in the mechanisms that regulate the formation or plasticity of synaptic networks has been proposed. Here we show, using a transient transfection approach, that antisense and small interfering RNA-mediated suppression of PAK3 or expression of a dominant-negative PAK3 carrying the human MRX30 mutation in rat hippocampal organotypic slice cultures results in the formation of abnormally elongated dendritic spines and filopodia-like protrusions and a decrease in mature spine synapses. Ultrastructural analysis of the changes induced by expression of PAK3 carrying the MRX30 mutation reveals that many elongated spines fail to express postsynaptic densities or contact presynaptic terminals. These defects are associated with a reduced spontaneous activity, altered expression of AMPA-type glutamate receptors, and defective long-term potentiation. Together, these data identify PAK3 as a key regulator of synapse formation and plasticity in the hippocampus and support interpretations that these defects might contribute to the cognitive deficits underlying this form of mental retardation. -
