Sequencing of methylated GATC DNA fragments (Targeted DamID) from seven olfactory neuron populations in Drosophila melanogaster

Project description:This project’s aim was to compare the transcriptional profiles of olfactory sensory neurons in Drosophila melanogaster in order to identify novel genes that specify neuron-specific functions/phenotypes or may otherwise be involved in the development of the olfactory system. The isolation of sufficient numbers of intact olfactory sensory neurons (OSN) from the antenna of Drosophila melanogaster has so far limited single-cell transcriptomic approaches being applied to the adult fly antenna. Targeted DamID (TaDa) provides an alternative approach for profiling transcriptional activity in a cell-specific manor that bypasses the need for isolating OSN. Using the Gal4/UAS system, we applied TaDa to seven OSN populations and compared differences in Pol II occupancy for genes across these datasets.

HS-30-48H Drosophila antennae

Project description:Environmental temperature directly affects the concentration of chemicals in the gas phase. Therefore, if the olfactory system does not adapt to environmental conditions may provide inadequate information about distance to or direction of odor sources. Previous reports in Drosophila melanogaster show that temperature induces changes in olfactory sensitivity in complete individuals. Electrophysiological analysis demonstrates that these changes initiate at the olfactory receptor organs. In this experiment we try to identify particular genes responsible for olfactory adaptation to increasing temperatures using receptor organs of Drosophila after exposure to high temperatures. With this aim, wild-type Canton-S flies were subjected to 48-hour treatments at 30 degrees C. We use a direct approach selecting the specific tissue and making 'a priori' the gene election for the microarray analysis. Differential gene-expression analyses at the third antennal segments are performed comparing control and treated flies.

Transcription Factors Sp8 and Sp9 Coordinately Regulate Olfactory Bulb Interneuron Development [ChIP-Seq]

Project description:We conducted RNA-Seq and in situ hybridization to identify transcriptional profile changes in the Sp8/Sp9-DCKO olfactory bulb. Simultaneously, we did ChIP-Seq with homemade Sp9 antibody to identify Sp9 binding motifs and which changed genes might be the direct targets of transcription factor Sp9. We found that Sp9 directly binded to key genes which are required for olfactory bulb development. Transcription factors Sp8 and Sp9 belong to the same transcription factor family, so we think Sp8 and Sp9 have very similar binding sites of transcriptional regulation.

Transcriptional Responses to Elevated Temperature in Streptococcus agalactiae

Project description:In the transition from recto-vaginal colonizing organism to invasive pathogen, Streptococcus agalactiae (Group B Streptococcus, GBS) must adapt to changes in host temperature, including elevated temperatures due to host fever. To identify genes important to the survival of GBS in response to heat stress, transcriptional profiling was performed using DNA microarray analysis, comparing GBS grown at normal temperature (37˚C) to GBS exposed to elevated temperature (42˚C).

Lamin b receptor regulates nuclear architecture and gene expression in olfactory neurons

Project description:Gene positioning and regulation of nuclear architecture are thought to influence gene expression. Here, we show that in mouse olfactory neurons, silent olfactory receptor (OR) genes from different chromosomes converge in a small number of heterochromatic foci. These foci are OR-exclusive and form in a cell-type-specific and differentiation- dependent manner. The aggregation of OR genes is developmentally synchronous with the downregulation of Lamin b Receptor (LBR) and can be reversed by ectopic expression of LBR in mature olfactory neurons. LBR-induced reorganization of nuclear architecture and redistribution of OR loci results in misregulation of OR transcription and disruption of the targeting specificity of the olfactory neurons. Our observations are consistent with a model of spatial regulation of OR expression and provide evidence for the instructive role of nuclear architecture and compartmentalization in gene regulation and differentiation. A complex probe was made by array capture to label mouse olfactory receptor genes by DNA FISH; this microarray data verifies the composition of that probe.

Warming Induces Significant Reprogramming of Beige, but Not Brown, Adipocyte Cellular Identity

Project description:Beige and brown adipocytes generate heat in response to reductions in ambient temperature. When warmed, both beige and brown adipocytes exhibit morphological ‘whitening’, but it is unknown whether or to what extent this represents a true shift in cellular identity. Using cell type-specific profiling in vivo, we uncover a unique paradigm of temperature-dependent epigenomic plasticity of beige, but not brown, adipocytes, with conversion from a brown to a white chromatin state. Despite this profound shift in cellular identity, warm whitened beige adipocytes retain an epigenomic memory of prior cold exposure defined by an array of poised enhancers that prime thermogenic genes for rapid response during a second bout of cold exposure. We further show that a transcriptional cascade involving the glucocorticoid receptor and Zfp423 can drive warm-induced whitening of beige adipocytes. These studies identify the epigenomic and transcriptional bases of an extraordinary example of cellular plasticity in response to environmental signals.

Identification of a microRNA regulator for axon guidance in the olfactory bulb of adult mice

Project description:Using the highly sensitive miRNA array, we screened 40 microRNAs abundant in the olfactory bulb and we explored the functions of these miRNAs in the olfactory bulb by Gene Ontology and Kyoto Encyclopedia of Genes annotation. The enrichment results indicated that these miRNAs mainly participated in the axon guidance process. Furthermore, the quantitative real-time polymerase chain reaction, immunohistochemistry, and dual luciferase reporter assay results showed that miR-30c is a specific regulator of semaphorin-3A, which will give new insights in disclosing the mechanism of functional maintenance and sexual-specific differentiation of the olfactory bulb.
