Transcription profiling of neurons or astrocytes treated with grape seed extract

ABSTRACT: We examined the effect of grape seed extract (GSE), which are known to protect neurons against oxidative stress, on primary cultures of hippocampal astrocytes. GSE increased interleukin-6 (IL-6) expression. Microarrays are used to examine the effects of GSE on primary cultures of hippocampal neurons and astrocytes. Experiment Overall Design: Primary cultures of hippocampal neurons were treated with 0, 1, or 10 ug/ml of GSE for 24 hrs. Primary cultures of hippocampal astrocytes were treated with 0, 1, 10, or 100 ug/ml of GSE for 24 hrs.

Gene expression after type-I interferon treatment in primary neurons, primary fibroblasts and L929 cells

Project description:Microarray expression profilling of mouse primary mixed cortical/hippocampal neurons, primary fibroblasts and L929 cells to compare ISGs signature in disctinct cell types Primary mixed cortical/hippocampal neurons, primary fibroblasts (MEFs) and L929 cells were mock-treated or treated with 5U/mL of IFN-beta and RNA was harvested after 24 hours. For neurons and fibroblast, 2 samples were analyzed for each condition.

Expression data from Soma dissected from single-cell mouse Hippocampal neurons

Project description:To assess neuronal expression divergence between mice and rats, we used the Affymetrix array platform to assay the transcriptomes of micro-dissected individual soma and pool of dendrites of hippocampal neurons in dispersed primary cell cultures from rat and mouse. Using microdissected soma and dendrites from primary cultures of hippocampal neurons of two mouse strains (C57BL/6 and Balb/c) and one rat strain (Sprague-Dawley), we investigate via microarrays, subcellular localization of mRNAs in neurons

Genes induced after BDV infection in Sprague Dawley and Lewis rats

Project description:Borna Disease Virus (BDV) is a neurotropic virus that persistently infects neurons in the central nervous system of various hosts, including rats. Although BDV is known to be an IFN sensitive virus, determination of the cellular mRNA transcript levels revealed the induction of IFN-stimulated genes in organotypic rat hippocampus slice cultures, raising the question how BDV evades this innate immune response. Using rat Mx protein as a specific marker for IFN-induced gene products, we could show that neurons lack detectable levels of Mx in these BDV infected cultures, whereas astrocytes and microglial cells were Mx positive. Neurons remained Mx negative after treatment of uninfected hippocampus cultures as well as primary dissociated neuronal cultures with high concentrations of IFN-M-NM-1. This non-responsiveness correlated with a lack of a detectable nuclear translocation of pSTAT1 in rat neurons. Consistently, IFN treatment of BDV-infected rat neurons did not prevent the establishment of a viral persistence in the neuronal tissue. However, IFN treatment efficiently prevented vesicular stomatitis virus (VSV) replication, indicating that these cells can mount a weak innate immune response. In contrast, IFN treatment of mouse neurons resulted in the upregulation of Mx1 proteins and inhibition of BDV replication, indicating species-specific differences in the IFN response in neurons between mice and rats. Rat neurons may therefore represent the ideal cell type for BDV to evade the innate immune in the central nervous system. To determine the mRNA levels in the hippocampal slice cultures after BDV infection in Sprague Dawley and Lewis rats Hippocampal slice cultures were prepared from newborn Lewis and SD rats (P0-P2). Half of the samples remained uninfected, whereas the other half was infected with 1000 focus forming units (FFU) of BDV strain He/80. Total RNA from a pool of 12 slice cultures was prepared

Gene-expression profiles of primary cultures of cortical neurons and astrocytes.

Project description:We used microarrays to compare the global programme of gene expression in primary cultures of neurons and astrocytes. These data sets were compared to the expression profiles of other tissues, including pancreatic islets, in order to identify a specific neuroendocrine program in pancreatic islets. Neurons and astrocytes were isolated from brain cortex and cultured in vitro for 7 and 20 days respectively. RNA was extracted and hybridized on Affymetrix microarrays. Two biological samples from neurons and astrocytes were analyzed.

Rat Astrocyte-Neuron Co-cultures versus purified co-cultured Astrocytes versus Astrocyte alone

Project description:Profiling of transcriptional changes in rat astrocytes when co-cultured with neurons: comparison of astrocytes cultured alone with astrocytes co-cultured with mouse hippocampal neurons. Co-cultured astrocytes are isolated using cold jet, a novel tool for these neuron-glia cultures. Over the last decade, the importance of astrocyte-neuron communication in neuronal development and synaptic plasticity has become increasingly clear. Since neuron-astrocyte interactions represent highly dynamic and reciprocal processes, we hypothesized that at least part of the involved astrocyte genes may be regulated as a consequence of their interactions with maturing neurons. In order to identify such neuron-induced astrocyte genes in vitro, we tested the effectiveness of the ‘cold jet’, a new method for separation of neurons from co-cultured astrocytes. The cold jet method is performed under ice-cold conditions and avoids protease-mediated isolation of astrocytes or time-consuming centrifugation, yielding intact astrocyte mRNA with approximately 90% of neuronal RNA removed. Using this method, we executed genome-wide profiling in which RNA derived from astrocyte-only cultures was compared with astrocyte RNA derived from differentiating neuron-astrocyte co-cultures. Data analysis revealed changes in expression of a large number of mRNAs and biological processes, including novel findings. Thus, cold jet is an efficient method to separate astrocytes from neurons in co-culture, and in this study reveals that neurons induce robust gene-expression changes in co-cultured astrocytes.

Expression data from mouse dissected dendrites

Project description:Using microdissected dendrites from primary cultures of hippocampal neurons of two mouse strains (C57BL/6 and Balb/c) and one rat strain (Sprague-Dawley), we investigate via microarrays, subcellular localization of mRNAs in dendrites of neurons to assay the evolutionary differences in subcellular dendritic transcripts localization. To assess neuronal dendrite expression divergence between mice and rats, we used the Affymetrix array platform to assay the transcriptomes of micro-dissected individual dendrites of hippocampal neurons in dispersed primary cell cultures from Sprague-Dawley rat (9 biological replicates), C57BL/6 mouse (14 biological replicates), and Balb/c mouse (5 biological replicates)
