Project description:The goal of scRNA-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 in a large and unbias scale. Olfactory epithelial single cell suspensions were made using 3 male and 3 female mice. Single-cell sequencing libraries were prepared using Chromium Single Cell 3’ Reagent Kit V3 (10X Genomics) according to the manufacturer’s guidelines. Libraries were sequenced using 150 cycles of paired end reads on Illumina Hiseq4000 and Novaseq6000 instruments (Novogene). The sequencing reads were processed using the DolphinNext Single Cell-10X Genomics pipeline (https://dolphinnext.umassmed.edu/index.php?np=1&id=420, default settings except STAR v2.6.1 was used for alignment).

Project description:We have identified a replication-independent histone variant, Hist2h2be (referred to herein as H2be), which is expressed exclusively by olfactory chemosensory neurons. Levels of H2BE are heterogeneous among olfactory neurons, but stereotyped according to the identity of the co-expressed olfactory receptor (OR). Gain- and loss-of-function experiments demonstrate that changes in H2be expression affect olfactory function and OR representation in the adult olfactory epithelium. We show that H2BE expression is reduced by sensory activity and that it promotes neuronal cell death, such that inactive olfactory neurons display higher levels of the variant and shorter life spans. Post-translational modifications (PTMs) of H2BE differ from those of the canonical H2B, consistent with a role for H2BE in altering transcription. We propose a physiological function for H2be in modulating olfactory neuron population dynamics to adapt the OR repertoire to the environment. The objective of generating this dataset was to analyze the effects of H2be loss of function on gene expression in the main olfactory epithelium of 6-month old mice. This dataset compares gene expression in wild type and H2be-KO main olfactory epithelium (MOE) samples. There are six replicates for each genotype (equal mixture of males and females).

We propose a physiological function for H2be in modulating olfactory neuron population dynamics to adapt the OR repertoire to the environment. The objective of generating this dataset was to analyze the effects of the ectopic over-expression of H2be (expressed from an Omp-promoter-driven transgene and tagged with a FLAG epitope) on gene expression in the main olfactory epithelium of 5-week old mice. This dataset compares gene expression in wild type and H2be-GF main olfactory epithelium (MOE) samples. There are 6 replicates for WT and 4 replicates for H2be-GF (equal mixture of males and females).

Project description:This study aims to identify the molecular basis for age-related decline in olfactory function and regeneration. To extend our characterization of olfactory stem cell regeneration during aging, we performed single-cell RNA sequencing on whole olfactory epithelium (OE) of 2-month-old and 18-month-old mice in uninjured state and at 24 hours after injury.
