Project description:single olfactory sensory neurons
| PRJEB7425 | ENA
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:Identification of all genes expressed by mouse olfactory sensory neurons; genes expressed in mature neurons, immature neurons, or both were distinguished. Independent validation of enrichment ratio values supported by statistical assessment of error rates was used to build a database of statistical probabilities of the expression of all mRNAs detected in mature neurons, immature neurons, both types of neurons (shared), and the residual population of all other cell types. FACS was used to separate a highly GFP+++ sample enriched in immature neurons, a weakly GFP+ sample slightly enriched in mature neurons, and a GFP- sample that contained all cell types in the olfactory epithelium but depleted of immature neurons.

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:The goal of RNA-seq is to explore whether olfactory sensory neurons (OSNs) that display a specific olfactory receptor (OR) express a distinct transcriptional program from OSNs that display a different OR. The GFP knockin mice (Olfr73-IRES-GFP, Olfr1507-IRES-GFP, and Olfr160-IRES-mCherry) was used to label the OSN expressing specific OR. These cells was then isolate with fluorescence activated cell sorting. For each sample, at least 5000 cells are collected, there biological replicates were collected for each genotype and in total 9 samples were prepared for RNA-seq libraries with using NEBNext® Single Cell/Low Input RNA Library Prep Kit for Illumina® (NEB) following the manufacturer’s guidelines with one alteration, which was to increase the insert length to ~300 base pair. Libraries were sequenced using paired end 150 cycle reads on an Illumina Hiseq4000 (Novogene). The sequencing reads were processed using the DolphinNext RNAseq pipeline (https://dolphinnext.umassmed.edu/index.php?np=1&id=732). The default settings were employed except STAR v2.6.1 and RSEM v1.3.1 were used for alignment and quantification, respectively. Differential analysis were conducted in DESeq2. The significant genes were deducted by computing Wald test with corrected p < 0.05. Our results shows that different types of OSNs express significantly different patterns of genes, especially the genes involved in axonal guidance.
