Project description:We assessed astrocyte diversity in the cortex, hippocampus, and striatum using sing cell RNA-seq (scRNA-seq). We also assessed cortical astrocytes in wild type control and transgenic APP/PS1dE9 mice using scRNA-seq.
Project description:Transcriptional profiling of mouse primary astrocytes comparing control untreated astrocytes with astrocytes treated with recombinant LCN2 protein (10 micro gram/ml). Goal was to determine the effects of LCN2 treatment on global gene expression in astrocytes. A secreted protein lipocalin-2 (LCN2) has been implicated in diverse cellular processes including cell morphology and migration. We have previously demonstrated that lcn2 mediates reactive astrocytosis. In order to further understand the role of lcn2 in the CNS, astrocyte transcriptome was analyzed following LCN2 treatment. Chemokines were the major group of genes upregulated by LCN2. Two-condition experiment, control untreated astrocytes vs. LCN2 protein treated astrocytes. Biological replicates: 1 control replicates, 1 treated replicates.

Project description:A robust set of CNS transcript changes was defined by comparing microarray data that describe the injury response of the rat retina [Vazquez-Chona et al., IOVS 2004; GSE1001], brain [Matzilevich et al., J Neurosci Res 2002; GSE1911], and spinal cord [Di Giovanni et al., Ann Neurol 2003; GDS63]. We determined the CNS injury genes that were expressed in cultured astrocytes from rat cortex [GSM34300] and from human optic nerve head [Yang et al., Physiol Genomics 2004; GDS532].
