Project description:The overall aim of the experiment is to understand the phenotype of mature mouse olfactory sensory neurons by analyzing the transcripts expressed and enriched in them as compared to the rest of the cell types in the olfactory epithelium (consisting of immature neurons, supporting cells, progenitor cells and cells in lamina propria) and brain ( with out the olfactory bulbs). Comparision with the other cell types in the olfactory epithelium should eliminate the transcripts commonly expressed in the olfactory epithelium and comparision with brain will eliminate the transcripts common to most neurons. Our gene chip data indicates that mature mouse olfactory sensory neurons express 10,000 genes. Mature OSNs specifically contained three clusters of over represented Gene ontology categories: smell, ion transport and cilia. Analysis for the functionally over represented categories among the transcripts with a positive signal in the mature OSNs yielded largely broad categories common to all cells with the exception of chromatin modelling and RNA processing categories. Biological process categories of movement, development and immune response came as under represented categories. Experiment Overall Design: To purify mature olfactory neurons we took advantage of the OMP-GFP mice. OMP(olfactory marker protein) is expressed specifically in mature olfactory and vomeronasal sensory neurons. In the OMP-GFP mice the coding region of OMP is replaced by GFP. We purified OSNs from the rest of the epithelium from these mice by using FACS. . We used the Affymetrix gene chips mouse expression set 430 (consisting of 430A and 430B chips). Our gene chip data is extensively validated by insitu hybridizations.

Project description:Olfactory sensory neurons (OSNs) express a single abundant olfactory receptor (OR). To assess the differences in gene expression between different OSN sub-types we collected three pools of neurons that express one OR and compared them to three pools of neurons that express another. After extracting RNA from these pools, the samples were multiplexed and sequenced using the Illumina Hiseq2500 platform.This data is part of a pre-publication release.

Project description:Transcriptomic analysis of two cellular populations of the mouse olfactory mucosa. 6 x 10,000 olfactory sensory neurons (OSNs) were captured by FACS. Three samples from a high OMP-expressing population and three from a low OMP-expressing population. The RNA from each sample was sequenced on the Illumina Hiseq platform. This data is part of a pre-publication release.

Project description:Olfaction plays important roles in food and mate choice, and also in the avoidance of predators, making it a vital sensory modality for preservation and reproduction. In the vertebrates, olfactory receptors are thought to localise on multiple cilia elaborated on the dendritic knobs of olfactory sensory neurons (OSNs). Although olfactory cilia dysfunction can cause loss of the sense of smell, how their differentiation is programmed at the transcriptional level has remained largely unexplored. We discovered in zebrafish and mice that Foxj1, a fork head-domain containing transcription factor traditionally linked with motile cilia biogenesis, is expressed in OSNs and required for olfactory epithelium formation. In keeping with the immotile nature of the olfactory cilia, we observed that ciliary motility genes that are the targets of Foxj1 in motile ciliated cells, are repressed in the OSNs. Strikingly, we also found that besides ciliogenesis, Foxj1 controls the differentiation of the OSNs by regulating their cell type-specific gene expression, such as that of olfactory marker protein (omp) involved in odour-evoked signal transduction. In line with these requirements, response to bile acid, an odour detected by OMP-positive OSNs, was significantly diminished in the foxj1 mutant zebrafish. Taken together, our findings establish how the canonical Foxj1-mediated motile ciliogenic transcriptional program has been repurposed for the biogenesis of the immotile olfactory cilia and for the development of the OSNs themselves.

Project description:This experiment studies the gene expression in the mature olfactory sensory neurons and the intermidiate neuronal progenitors in the olfactory epithelia during the critical period. Mature olfactory sensory neurons from OMP-GFP mice and intermediate neuronal progenitors in the olfactory epithelia from Neurog1-GFP mice were FACS purified. PolyA RNA profiles at P2, P3, P7, P9, and P16 were generated by RNA-Seq.
