RNA profile of nuclei isolated from neurons coexpressing VAChT and VGlut or VAChT and VGAT

ABSTRACT: The concept of neurotransmitter identity, once considered singular and immutable for mature neurons, has been broadened by the recognition that many neurons release multiple neuro-active substances. In order to demonstrate the extent of neurotransmitter co-expression, we labelled neuronal nuclei with UNC84-GFP using VAChT and either Vglut or VGAT split-GAL4s and isolated them with the isolation of nuclei tagged in specific ell types (INTACT) method From the isolated nuclei, we isolated and sequenced Poly(A) RNA and examined the relative expression levels of glutamatergic, GABAergic, or cholinergic genes in each population.

Single nuclei RNA-seq from adult mouse Hippocampus

Single nuclei RNA-seq from adult mouse Hippocampus

Project description:We report RNA-seq of single nuclei isolated from the adult C57BL/6 male mouse Hippocampus region. Majority of the nuclei were isolated from 12 weeks old mice (4 different animal), with an additional set of nuclei from 3 months and 2 years old animals. In addition a set of GFP labeled nuclei driven by a VGAT promoter . Microdissections of dentate gyrus, CA1 and CA2/3 regions of the Hippocampus were placed into ice-cold RNA-later for fixation and stored at 4âc overnight, then stored in -80âc. Nuclei were isolated by sucrose gradient centrifugation and kept on ice until sorting using Fluorescence Activated Cell Sorting (FACS) into 96 well plates containing RNA lysis buffer. Single nucleus RNA was first purified then derived cDNA libraries were generated following a modified Smart-seq2 protocol. For VGAT nuclei: high titer AAV1/2 of pAAV-EF1a-DIO-EYFP-KASH-WPRE-hGH-polyA was injected into dorsal and/or ventral Hippocampus, animals were sacrificed two weeks after injections, and GFP labeled nuclei were sorted into plates and processed as described above.

Asynchronous transcription and translation of neurotrasmitter-related genes characterize the initial stages of neuronal maturation in Drosophila

Project description:Neuron specification and maturation are essential for proper central nervous system development. However, the precise mechanisms that govern neuronal maturation, essential to shape and maintain neuronal circuitry, remain poorly understood. Here, we analyse early-born secondary neurons in the Drosophila larval brain revealing that the early maturation of secondary neurons goes through three consecutive phases: 1) Immediately after birth, neurons express pan-neuronal markers but do not transcribe terminal differentiation genes; 2) Transcription of terminal differentiation genes, such as neurotransmitter-related genes VGlut, ChAT or Gad1, starts shortly after neuron birth, but these transcripts are however not translated; 3) Translation of neurotransmitter-related genes only begins several hours later in mid pupa stages in a coordinated manner with animal developmental stage, albeit in an ecdysone independent-manner. These results support a model where temporal regulation of transcription and translation of neurotransmitter-related genes is an important mechanism to coordinate neuron maturation with brain development.

Expression data from WT and VAChT KDHOM ventricles

Project description:VAChT KDHOM mice have a 70% decrease in the vesicular acetylcholine transporter (VAChT) and this leads to a systemic decrease in ACh release and cardiac dysfunction. We used this microarray to determine whether there were transcriptional alterations in the hearts of mutant mice as a result of this long-term decrease in cholinergic tone. We isolated whole hearts from 3-month-old WT and VAChT KD mice and used them for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain homogenous populations for each sample and, as such, pooled together two RNA samples to generate one microarray sample.

Transcriptomic atlas of thalamic nuclei

Project description:We profiled the transcriptome of 22 thalamic nuclei. Nuclei were retrogradely labeled from their forebrain target areas, microdissected and fluorescent cells pooled. Anterograde tracing was used when identification of nuclear boundaries was ambiguous. We found that thalamic nuclei share a common axis of variance closely linked to the mediolateral spatial axis of thalamus. This axis was enriched in functionally relevant genes such as neurotransmitter receptors and ion channels, and was closely linked to functional and morphological properties of the neurons.

Transcription profiling of Drosophila embryonic cell culture and embryonic neural tissues FACS sorted for neuronal type to examine determination the neuronal cellular fate and specific neurotransmitter phenotypes of cells in the nervous system

Project description:We are interested in genes that determine the neuronal cellular fate and specific neurotransmitter phenotypes of cells in the nervous system. The reasons for our interest are two fold. First, identification of the genetic pathways operating in specific types of neurons could explain why they die in neurodegenerative diseases such as Alzheimer?s, Parkinson?s and amyotrophic lateral sclerosis. All of these disorders have in common the property that only certain types of neurotransmitter specific neurons degenerate. Secondly, neuronal cell replacement therapies using differentiated stem cell progeny hold the potential to reverse the devastating consequences of neurodegenerative diseases. The genetic personality of specific kinds of neurons must first be defined in order to use proper cells for neuronal replacement and this information will be essential in directing stem cell differentiation into proper developmental pathways. Our current approach to the problems of specification and neurotransmitter phenotype is to create transgenic animals where different neurotransmitter phenotypes are labeled with a fluorescent reporter gene. Labeled neurons are then isolated using Fluorescence Activated Cell Sorting. The purified populations of neurons are analyzed for their whole genome expression patterns using DNA microarray technology. We have successfully applied this approach using Drosophila cholinergic neurons and are now extending our observations to other classes of neurons that use GABA or glutamate as neurotransmitters. Cholinergic neurons express unique sets of ion channels, receptors and other types of genes. We also see unique sets of transcriptional regulatory proteins, and these may be important in the developmental pathways that result in the production of cholinergic neurons.

Mouse psd95 coimmunoprecipitation from excitatory or inhibitory neurons and mass spectrometry

Project description:We used a psd95-GFP cre dependent KI mouse to label PSD95 with GFP specifically in excitatory (CaMK) or inhibitory (vGAT) neurons. PSD95 was pulled down with a GFP nanobody and the resulting complex was used for massspectrometry analysis.

Cell type-specific gene expression profiling of Drosophila neurons [RNA-Seq]

Project description:Gene expression profiling of nuclei isolated from genetically defined neuronal subpopulations of the adult Drosophila brain. Gene expression profiles were generated from nuclei isolated from all neurons (R57C10-GAL4), Kenyon cells (OK107-GAL4), and octopaminergic (Tdc2-GAL4) neurons in the adult Drosophila head using a method similar to INTACT (Deal and Henikoff, 2010; Steinner et al., 2012). Sequencing was performed with an Illumina HiSeq 2000.
