    RESEARCH ARTICLE elifesciences.org Genetic transformation of structural and functional circuitry rewires the Drosophila brain Sonia Sen1,2, Deshou Cao3, Ramveer Choudhary1,4, Silvia Biagini1,4, Jing W Wang3, Heinrich Reichert5, K VijayRaghavan1* 1Department of Developmental Biology and Genetics, National Centre for Biological Sciences, Tata Institute for Fundamental Research, Bangalore, India; 2Manipal University, Manipal, India; 3Division of Biological Sciences, University of California, San Diego, San Diego, United States; 4Institute for Molecular Oncology, Milan, Italy; 5Department of Biozentrum, University of Basel, Basel, Switzerland Abstract Acquisition of distinct neuronal identities during development is critical for the assembly of diverse functional neural circuits in the brain. In both vertebrates and invertebrates, intrinsic determinants are thought to act in neural progenitors to specify their identity and the identity of their neuronal progeny. However, the extent to which individual factors can contribute to this is poorly understood. We investigate the role of orthodenticle in the specification of an identified neuroblast (neuronal progenitor) lineage in the Drosophila brain. Loss of orthodenticle from this neuroblast affects molecular properties, neuroanatomical features, and functional inputs of progeny neurons, such that an entire central complex lineage transforms into a functional olfactory projection neuron lineage. This ability to change functional macrocircuitry of the brain through changes in gene expression in a single neuroblast reveals a surprising capacity for novel circuit formation in the brain and provides a paradigm for large-scale evolutionary modification of circuitry.

  • The Labial Gene Is Required to Terminate Proliferation of Identified Neuroblasts in Postembryonic Development of the Drosophila Brain Philipp A
    © 2016. Published by The Company of Biologists Ltd | Biology Open (2016) 0, 1 doi:10.1242/bio.020230 CORRECTION The labial gene is required to terminate proliferation of identified neuroblasts in postembryonic development of the Drosophila brain Philipp A. Kuert, Bruno C. Bello and Heinrich Reichert There were two errors published in Biol. Open 1, 1006-1015. 1. Nomenclature: The lineages as previously published in Pereanu and Hartenstein (2006) should have been TRdl instead of TRld, and TRvl instead of TRlv. This affects all instances in the text as well as Figs 2; 3A-D; 4A,B,E,F; 6C,K; 7A,B,E,F and 8, and Fig. S1. 2. The late embryonic stage mentioned on pages 1012, 1014, and in Fig. 8 and Fig. S2 should have been stage 16 and not stage 17. These errors do not affect the conclusions of the paper. The authors apologise to the readers for any confusion that these errors might have caused.

    Hindawi Publishing Corporation Stem Cells International Volume 2012, Article ID 486169, 10 pages doi:10.1155/2012/486169 Review Article Neural Stem Cells in Drosophila: Molecular Genetic Mechanisms Underlying Normal Neural Proliferation and Abnormal Brain Tumor Formation Nidhi Saini and Heinrich Reichert Biozentrum, University of Basel, 4056 Basel, Switzerland Correspondence should be addressed to Nidhi Saini, [email protected] Received 23 November 2011; Accepted 31 March 2012 Academic Editor: Mark LaBarge Copyright © 2012 N. Saini and H. Reichert. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Neural stem cells in Drosophila are currently one of the best model systems for understanding stem cell biology during normal development and during abnormal development of stem cell-derived brain tumors. In Drosophila brain development, the proliferative activity of neural stem cells called neuroblasts gives rise to both the optic lobe and the central brain ganglia, and asymmetric cell divisions are key features of this proliferation. The molecular mechanisms that underlie the asymmetric cell divisions by which these neuroblasts self-renew and generate lineages of differentiating progeny have been studied extensively and involve two major protein complexes, the apical complex which maintains polarity and controls spindle orientation and the basal complex which is comprised of cell fate determinants and their adaptors that are segregated into the differentiating daughter cells during mitosis. Recent molecular genetic work has established Drosophila neuroblasts as a model for neural stem cell-derived tumors in which perturbation of key molecular mechanisms that control neuroblast proliferation and the asymmetric segregation of cell fate determinants lead to brain tumor formation.

  • The Asymmetrically Segregating Lncrna Cherub Is Required For
    RESEARCH ARTICLE The asymmetrically segregating lncRNA cherub is required for transforming stem cells into malignant cells Lisa Landskron1, Victoria Steinmann1, Francois Bonnay1, Thomas R Burkard1, Jonas Steinmann1, Ilka Reichardt1, Heike Harzer1, Anne-Sophie Laurenson2, Heinrich Reichert2, Ju¨ rgen A Knoblich1* 1IMBA, Institute of Molecular Biotechnology of the Austrian Academy of Sciences, Vienna, Austria; 2Biozentrum, University of Basel, Basel, Switzerland Abstract Tumor cells display features that are not found in healthy cells. How they become immortal and how their specific features can be exploited to combat tumorigenesis are key questions in tumor biology. Here we describe the long non-coding RNA cherub that is critically required for the development of brain tumors in Drosophila but is dispensable for normal development. In mitotic Drosophila neural stem cells, cherub localizes to the cell periphery and segregates into the differentiating daughter cell. During tumorigenesis, de-differentiation of cherub-high cells leads to the formation of tumorigenic stem cells that accumulate abnormally high cherub levels. We show that cherub establishes a molecular link between the RNA-binding proteins Staufen and Syncrip. As Syncrip is part of the molecular machinery specifying temporal identity in neural stem cells, we propose that tumor cells proliferate indefinitely, because cherub accumulation no longer allows them to complete their temporal neurogenesis program.
