Project description:The RNA sequencing data are part of a study reporting and investigating a mouse model of the Say-Barber-Biesecker-Young-Simpson (SBBYS) syndrome (OMIM:603736) and demonstrating proof-of-principle efficacy of postnatal treatment with sodium valproate (VPA) or acetyl-carnitine (ALCAR). The KAT6B gene encodes a histone lysine acetyltransferase. The RNA sequencing experiments identified genes that are differentially expressed between Vehicle treated Kat6b+/– and Kat6b+/+ cortical neurons and the subset genes that are restored to normal expression after treatment with ALCAR or VPA. Cortical neurons were isolated from four Kat6b+/– and four Kat6b+/+ E16.5 mouse cerebral cortex. Cells from each cortical neuron isolate were cultured with 1 mM ALCAR, 1 mM VPA or untreated medium (Vehicle) for 4 days.
Project description:To develop our gene expression experiment, we have employed whole genome microarray expression profiling as a discovery platform to identify genes potentially regulated by the transcriptional coactivator KAT6B. Expression of KAT6B gene was downregulated in two human SCLC cell lines using two different short hairpin RNAs. RNAs from these modified cell lines were hybridized in Agilent platform.

Project description:To understand the effect of reducing miR-27b levels on genome-wide expression in cortical neurons and identify potential targets of miR-27b, we generated dissociated cortical neuron cultures and treated them with lentivirus to knock down miR-27b. 2 treatment conditions (control lentivirus or lentivirus to knock down miR-27b); 3 neuronal preparations of dissociated mouse cortical neurons; total of 6 samples
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.
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:E18 embryonic rat cortical neurons cultured in vitro are infected with lentivirus expressing control or PHF6shRNA-2, and harvested 5 days after infection pLL3.7 lentivirus expressing control or PHF6shRNA-2 was generated in 293T cells and concentrated using ultracentrifuge. In vitro cultured cortical neurons were infected and RNA was harvested 5 days after infection. PHF6 knockdown was validated by QPCR before sample was processed for microarray analysis.
