Identification of Phox2b-regulated genes by expression profiling of cranial motoneuron precursors.

Neural development 20080619

<h4>Background</h4>Branchiomotor neurons comprise an important class of cranial motor neurons that innervate the branchial-arch-derived muscles of the face, jaw and neck. They arise in the ventralmost progenitor domain of the rhombencephalon characterized by expression of the homeodomain transcription factors Nkx2.2 and Phox2b. Phox2b in particular plays a key role in the specification of branchiomotor neurons. In its absence, generic neuronal differentiation is defective in the progenitor domai ...[more]

Identification of Phox2b-regulated genes by expression profiling of cranial motoneuron precursors on NIA 15k microarray

Project description:Branchiomotor neurons are an important class of cranial motor neurons that innervate the branchial-arch-derived muscles of the face, jaw and neck. They arise in the ventralmost progenitor domain of the rhombencephalon characterized by expression of the homeodomain transcription factors Nkx2.2 and Phox2b. Phox2b in particular plays a key role in the specification of branchiomotor neurons. In its absence, generic neuronal differentiation is defective in the progenitor domain, and no branchiomotor neurons are produced. Conversely, ectopic expression of Phox2b in spinal regions of the neural tube promotes cell cycle exit and neuronal differentiation and at the same time induces genes and an axonal phenotype characteristic for branchiomotor neurons. How Phox2b exerts its pleiotropic functions, both as a proneural gene and a neuronal subtype determinant, has remained unknown. To gain further insight into the genetic programme downstream of Phox2b we searched for novel Phox2b-regulated genes by cDNA microarray (here NIA 15k slides) analysis of facial branchiomotor neuron precursors from heterozygous and homozygous Phox2b mutant embryos. Keywords: Phox2b-regulated genes identification Four biological replicates each in dye swap

Looking for mitochondrial associated RNA

Project description:We investigated the peripheral mitochondrial localization of nuclear-encoded mRNAs (MLR) in various conditions in which translation was inhibited or the mRNA binding protein context altered (Delta puf3). We used cell fractionation protocols together with microarray to assess the distribution of mRNAs between free and mitochondrion-bound polysomes. Keywords: Mitochondrial-associated RNA localization in cells GSM239122-GSM239127: mitochondrial associated RNA (three biological replicates each in dye swap) GSM239128-GSM239131: mitochondrial associated RNA in presence of 200µg/ml cycloheximide (two biological replicates each in dye swap) GSM239132-GSM239135: mitochondrial associated RNA in presence of 2.1mM puromycin (two biological replicates each in dye swap) GSM239136-GSM239139: mitochondrial associated RNA in Delta Puf3 strain (two biological replicates each in dye swap)

New schwann cell markers identified by gene profiling analysis after axonal contact

Project description:Elucidating the genes regulated during cell-cell communication remains fascinating considering the importance of cell recognition and downstream signaling through development and in many diseases. In the peripheral nervous system, the interaction between Schwann cells (SCs) and axons is crucial as it allows their survival and induces SCs to differentiate and engage a process of myelination. To get further insight the molecular mechanisms resulting from this cell interaction, comparative gene analysis between SCs and SCs co-cultured with DRG neurons were performed and led us to identify a set of 32 genes regulated in SCs in the early stage of neuron-SC contact. Expression of several candidates were analyzed by QPCR during development and we demonstrate using a blocking antibody approach in an in vitro myelination assay that one candidate was not only upregulated in response to axonal contact but also controls peripheral myelination. Three biological replicates each in dye swap for 22k slides and two biological replicates each in dye swap for NeuroDev2

Silicon metabolism in diatoms

Project description:We investigated the effects of extracellular silicic acid on the whole Phaeodactylum triconutum transcriptome. In this work, global transcription analyses were combined with comparative studies of other elements, and detailed analyses of the silicon transporters. Our results provide insight on Si-sensing genes and further extend current models for Si uptake. Keywords: Comparative transcriptome analyses from Phaeodactylum triconutum fusiform cells acclimated in a Si-free or silicic acid medium. Three biological samples in dye swap

Role of the AMP deaminase Amd1p in purines interconversion in Saccharomyces cerevisiae

Project description:In this work, we show that under specific conditions, defect in AMP deaminase activity strongly impairs yeast cell growth and we establish that AMP deaminase is required for correct balance between adenylic and guanylic nucleotides. Study of the Amd1p homologs, Yjl070p and Ybr284p, reveals that overexpression of these proteins cannot suppress phenotypes associated to /amd1/ deletion but instead mimic in a wild-type strain a loss of Amd1p function. Data presented combined global transcription analyses to measurements of intracellular nucleotides pools by HPLC. Keywords: yeast strains implied in purines interconversion. 4 biological samples in dye-swap.

Ploidy influences the cellular responses of gross chromosomal rearrangements in Saccharomyces cerevisiae

Project description:We investigated the effects of the ploidy on cellular response in strains carrying various types of gross chromosomal rearrangements. Fourteen mutated strains (6 haploid strains and 8 diploid strains) were compared to their associated parental strain (haploid or diploid parental strain). For each comparison, 2 microarray experiments implying biological replicates were performed.

Project description:We investigated the effects of adenine starvation on the global yeast transcriptome. In this work, global transcription analyses were combined with measurements of intracellular nucleotides pools by HPLC. The bas1delta strain grown with or without adenine was compared to the WT strain grown with or without adenine. For each comparison, we performed 2 technical replicates, swapping dyes.
