Different Fgfs Have Distinct Roles in Regulating Neurogenesis After Spinal Cord Injury in Zebrafish Yona Goldshmit1,2, Jean Kitty K
Goldshmit et al. Neural Development (2018) 13:24 https://doi.org/10.1186/s13064-018-0122-9 RESEARCHARTICLE Open Access Different Fgfs have distinct roles in regulating neurogenesis after spinal cord injury in zebrafish Yona Goldshmit1,2, Jean Kitty K. Y. Tang1, Ashley L. Siegel1, Phong D. Nguyen1, Jan Kaslin1, Peter D. Currie1 and Patricia R. Jusuf1,3* Abstract Background: Despite conserved developmental processes and organization of the vertebrate central nervous system, only some vertebrates including zebrafish can efficiently regenerate neural damage including after spinal cord injury. The mammalian spinal cord shows very limited regeneration and neurogenesis, resulting in permanent life-long functional impairment. Therefore, there is an urgent need to identify the cellular and molecular mechanisms that can drive efficient vertebrate neurogenesis following injury. A key pathway implicated in zebrafish neurogenesis is fibroblast growth factor signaling. Methods: In the present study we investigated the roles of distinctfibroblastgrowthfactormembersandtheir receptors in facilitating different aspects of neural development and regeneration at different timepoints following spinal cord injury. After spinal cord injury in adults and during larval development, loss and/or gain of Fgf signaling was combined with immunohistochemistry, in situ hybridization and transgenes marking motor neuron populations in in vivo zebrafish and in vitro mammalian PC12 cell culture models. Results: Fgf3 drives neurogenesis of Islet1 expressing motor neuron subtypes and mediate axonogenesis in cMet expressing motor neuron subtypes. We also demonstrate that the role of Fgf members are not necessarily simple recapitulating development. During development Fgf2, Fgf3 and Fgf8 mediate neurogenesis of Islet1 expressing neurons and neuronal sprouting of both, Islet1 and cMet expressing motor neurons. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

Olena Myronova The role of the S6K2 splice isoform in mTOR/S6K signalling and cellular functions 2 Abstract Ribosomal S6 kinase (S6K) is a member of the AGC family of serine/threonine protein kinases and plays a key role in diverse cellular processes, including cell growth, survival and metabolism. Activation of S6K by growth factors, amino acids, energy levels and hypoxia is mediated by the mTOR and PI3K signalling pathways. Dysregulation of S6K activity has been implicated in a number of human pathologies, including cancer, diabetes, obesity and ageing. -

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

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.
