Transcripts enriched in mouse olfactory sensory neurons

ABSTRACT: 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. Keywords: cell type comparison

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.

Transcription profiling of murine olfactory epithelium during neuronal death and replacement to study adult neurogenesis in the olfactory epithelium

Project description:Expression profiling of mRNA abundance in the adult mouse olfactory epithelium during replacement of OSNs forced by the bilateral ablation of the olfactory bulbs. The experiment was done on 6 week old male C57Bl/6 mice. Olfactory epithelium tissue samples were collected on days 1, 5, and 7 after bulbectomy. The cellular processes activated by bulbectomy include apoptosis of mature olfactory sensory neurons, infiltration of macrophages and dendritic cells, stimulation of proliferation of basal cell progenitors, and differentation of new sensory neurons.

Transcription profiling of mouse olfactory epithelium from heterozygous and homozygouse OMP-GFP animals

Project description:OMP is expressed only in mature olfactory sensory neurons, arguing that its function is specially suited to the needs of OSNs. However none of the properties of OMP suggest any direct role in regulating gene expression in OSNs. Our data confirms that gene expression in the olfactory epithelium of mice lacking OMP is indistinguishable from mice expressing OMP. We used affymerix M430v2.0 gene chips to cover as much of genome as possible and observed no statistically significant differences in mRNA abundance between the two genotypes.These results imply that OMPs ability to regulate signal transduction with in OSNs has little effect on gene expression and that its ability to promote mitosis in neighbouring cells (under culture conditions) is insufficiently active under normal laboratory housing conditions to generate detectable differences in gene expression patterns. Experiment Overall Design: The overall design of the experiment is to undertand the effect of OMP (olfactory marker protein) on gene expression in the olfactory epithelium. We isolated the olfactory epithelium from homozygous and heterozygous OMP-GFP mice, extracted the RNA and hybridized on to the mouse expression set 430 2.0 Chip.

Single-cell RNA-sequencing of OMP-GFP mouse olfactory sensory neurons

Project description:We sequenced the transcriptome of 34 single olfactory sensory neurons (OSNs) manually picked from OMP-GFP mice, ensuring the cells expressed high levels of GFP, a marker of mature OSNs. We pooled the olfactory mucosa from 2 male and 2 female animals, to obtain single-cell suspensions for cell picking. We only picked healthy-looking cells. From each, we constructed libraries for single-cell RNA-sequencing, to characterise the diversity of OR genes expressed.

Ldb1 mediates trans enhancement in mammals

Project description:The monoallelic expression of olfactory receptor (OR) genes is governed by a large number of intergenic enhancer elements that are located in intergenic regions of OR gene clusters. In mature olfactory sensory neurons (OSNs), multiple OR enhancers colocalize in an interchromosomal enhancer hub together with the active OR allele. Here we show that in OSNs OR enhancers are bound by Ldb1, but not general purpose mediators of nuclear architecture (CTCF or the cohesin complex subunit Rad21). Conditional deletion of Ldb1 in OSNs results in the dissolution of long range and interchromosomal contacts between OR Enhancers and in pervasive reductions in OR gene expression.

Single-cell transcriptomics reveals receptor transformations during olfactory neurogenesis

Project description:We report RNA sequencing of single olfactory neurons from mouse olfactory epithelium in developmental progression from progenitors to precursors to immature neurons to mature neurons. Most mature neurons expressed only one of ~ 1000 odorant receptor genes (Olfrs) at high levels, whereas many immature neurons expressed low levels of multiple Olfrs. Investigating expression of odorant receptors genes in mouse olfactory sensory neurons during development.

Transcriptome human nasal epithelium

Project description:1. Odors are detected, firstly, by olfactory sensory neurons (OSNs) in the olfactory epithelium of the nose. This neurons then project directly to the olfactory bulb in the brain. Olfaction depends on cellular regeneration of the OE, olfactory bulb and hippocampus, and on their continual re-wiring. The olfactory neural pathway includes regions of the frontal, temporal and limbic brain, which in turn overlap with brain areas involved in brain disorders. OSNs are the only aspect of the human brain exposed to the external environment. This not only makes them vulnerable to environmental changes, but also accessible for biomedical studies. We have already sequenced and developed a protocol for analyzing the transcriptome of mouse main olfactory epithelium and single OSNs. We propose here to perform a similar study for samples from the human olfactory epithelium. We have developed a minimally invasive method for obtaining human OSNs, among other cells from the nasal epithelium. In this experiment, we have obtained cell samples from the olfactory epithelium, including OSN, from healthy volunteers. We would like to further characterize them by RNA sequencing. This will give us valuable insight into human olfaction. It will also provide a first step into a new avenue to study, and find biomarkers for, brain diseases though the analysis of these easily available neurons.
