Whole transcriptome sequencing of E18 mouse cortex

Project description:We observed Csmd3-deficient mice exhibited growth retardation, atypical learning and memory behaviors. Futher, cortical neurons from mice lacking Csmd3 showed abnormal development. To identified the role of Csmd3 in cortex develepement, we performed whole transcriptome sequencing on embryonic 18 days cortex from Csmd3-/- and wild type mice. As a result, a total of 2133 differentially expressed genes (DEGs) were identified, including 1400 upregulated genes and 733 downregulated genes. Downregulated DEGs were mainly related to synaptic functions, while the upregulated DEGs were involved in multiple progresses related to cell-to-cell communication. In terms of cell type preference as referring to the single cell sequencing data in mouse neocortex at E18, downregulated DEGs were exlusively enriched into neurons and upregulated DEGs were involved with multiple cell types. Our study is the first detailed analyses of Csmd3 in development mouse cortex, identifing Csmd3 plays a pivotal role in synaptic organazation and transmission, also has an effect on glia-vascular inter-cellular communication.

Transcriptome profiling of embryonic cortex E18 and primary cortical neuron cultures deficient for the Amyloid Precursor Protein (APP)

Project description:The amyloid precursor protein (APP), an important player in the Alzheimer’s disease, regulates neurites formation and synaptic function by mechanisms still not fully understood. Its ability to control gene expression via its intracellular domain (AICD) was proposed to mediate several of these physiological functions. Here, we tested whether putative AICD target genes could be transcriptionally modified by the absence of APP in embryonic cortex (E18) and in primary cortical neurons during maturation after 3 or 7 days in vitro. Moreover, we aimed to identified novel APP dependent target genes that could be related to particular biological functions in the context of neuronal physiology.
