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: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: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.
