Project description:To clarify the functional properties of FUS, we established the differentially expressed alternative exons in FUS-silenced primary cortical neurons by using exon-sensitive microarray technology. We analyzed total RNA of primary cortical neuron infected with lentivirus expressing shRNA against mouse Fus or control. RNA was harvested 11 days after transfection.
Project description:We performed SlamSeq (thiol(SH)-linked alkylation for metabolic sequencing) to estimate mRNA half-lives in subcellular compartments (neurites, soma-cytoplasm and nucleus) of primary cortical neurons.
Project description:This experiment comprises RNA-seq data used to study evolutionary differences between humans and mice in neuronal activity-dependent transcriptional responses. Activity-dependent transcriptional responses in developing human stem cell-derived cortical neurons were compared with those induced in developing primary- or stem cell-derived mouse cortical neurons 4 hours after KCl-induced membrane depolarisation. Activity-dependent transcriptional responses were also measured in aneuploid mouse neurons carrying human chromosome 21, allowing study of the regulation of Hsa21 genes, plus their mouse orthologs, side-by-side in the same cellular environment of a mouse primary neuron.
Project description:Inhaled anesthetics produce many effects and bind to a large number of brain proteins, but it is not yet clear if this is accompanied by widespread changes in gene expression of the biological targets. Such changes in expression might implicate functionally important targets from the large pool of binding targets. Isolated primary cortical neurons were exposed to anesthetics and DNA oligonucleotide microarrays were used to detect and quantify transcriptional changes in neuronal tissue. Experiment Overall Design: Primary cortical neurons were treated with 1MAC, 3MAC Halothane and 3MAC Isoflurane, together with no drug control. Pool no drug control was used as Cy3 channel in all chips. The above drug treated and individual control samples were used in Cy5 channel.
Project description:Necdin, a pleiotropic protein expressed predominantly in postmitotic neurons of mammals, regulates neuronal development and survival by interacting with various regulatory proteins. To understand a novel function of necdin, we analyzed gene expression profile of primary cortical neurons prepared from necdin-null mice at embryonic day 14.5. Wild-type and necdin-null cortical cells were prepared from mice at embryonic day 14.5. These cells were incubated in Neurobasal medium supplemented with B27 and differentiated into neurons for 4 days (>97% MAP2-positive postmitotic neurons). Three mice per genotype were used for analysis.
