Characterization of Caenorhabditis elegans homologs of the Down syndrome candidate gene DYRK1AWilliam B Raich
Department of Biochemistry and Molecular Biophysics, Center for Neurobiology and Behavior, Columbia University College of Physicians and Surgeons, New York, New York 10032, USA
Genetics 163:571-80. 2003..Our results suggest that increased gene dosage of human DYRK1A in trisomy 21 may disrupt the function of fully differentiated neurons and that this disruption is reversible...

- Stem Cells and Cell Lineage SpecificationOliver Hobert; Fiscal Year: 2007....
- De-coding Cis-regulatory information on a Genome-Wide Level with Single Neuron ReOliver Hobert; Fiscal Year: 2009..We propose here to systematically decode cis-regulatory information on a genome-wide level and to determine the identity of a single neuron-specific gene expression program. ..
- De-coding Cis-regulatory information on a Genome-Wide Level with Single Neuron ReOliver Hobert; Fiscal Year: 2009..We propose here to systematically decode cis-regulatory information on a genome-wide level and to determine the identity of a single neuron-specific gene expression program. ..
- Diversity Along the Left/Right Axis in Nervous SystemOliver Hobert; Fiscal Year: 2007..Future genetic studies will determine how the asymmetric activity of these gene regulatory factors is triggered. Our studies may provide novel insights into the creation of cellular diversity in the nervous system. ..
- Genetic analysis of dopaminergic neuron specification in C.elegansOliver Hobert; Fiscal Year: 2010..We use genetic approaches in the simple model organism C.elegans to address how the expression of genes that are normally expressed in dopaminergic neurons is regulated. ..
- Function and development of a C. elegans GABAergic interneuronOliver Hobert; Fiscal Year: 2010..elegans (Aim #2). PUBLIC HEALTH RELEVANCE: We propose to study development and function of a single GABAergic interneuron in the nematode C. elegans using a combination of genetic, molecular and physiological approaches. ..
- Genome-wide expression profiling of miRNAs with single cell resolutionOliver Hobert; Fiscal Year: 2006..Moreover, it will (4) validate the "sensor strategy" to determine miRNA expression profiles in C. elegans, and (5) build a toolkit of potentially useful gfp cell fate markers. ..
- LIM HOMEOBOX GENE LIM-6 IN MOTOR NEURON DIFFERENTIATIONOliver Hobert; Fiscal Year: 2004..These studies may give important insights into the function of the vertebrate homologs of lim-6 as well and may reveal common themes of Lhx gene action. ..
- Left/right asymmetric neuronal cell fate specificationOliver Hobert; Fiscal Year: 2006..These studies may reveal fundamental principles of neuronal development and may shed light onto the elusive mechanisms of generating L/R asymmetry in the nervous system...
