RNA-seq analysis dataset: Hippocampal tissues from Emx1-Cre;Auts2-flox/flox and Auts2-flox/flox mice at P14

Project description:Previous studies have revealed that AUTS2 regulates cytoskeletal organization as well as gene expression during prenatal brain development. Its involvement in controlling synapses, however, remains unclear. Here, we report the increased dendritic spine formation in Auts2 mutant mice as well as the primary cultured neurons from Auts2 mutant mice. To investigate the involvement of AUTS2 function in the regulation of gene expression, we performed transcriptome analysis. RNA-seq on total RNA from the hippocampal tissues of Emx1Cre/+;Auts2flox/flox homozygous conditional KO mice at P14 reveals changes in gene associated with brain development including synapse formation. These results suggest that AUTS2 regulates the expression of genes that are related to synapse formation/function, and some of which may be involved in spine number restriction. Aberrant expression of such synaptic genes may cause synaptic dysfunction in patients with AUTS2 mutations.

Gene expression of microglia from wild type, Gba flox/flox; Nestin-Cre, and Gba flox/flox; Nestin-Cre; Mincle-/- mice

Project description:To investigate the contribution of Mincle in neuronopathic Gaucher disease, we established Gba flox/flox; Nestin-Cre mice and crossed them with Mincle deficient mice. RNA sequencing of microglia from these mice revealed Axl, a phaogocytic receptor was upregulated in Gba flox/flox; Nestin-Cre mice. In addition, Tnf was upregulated in Gba flox/flox; Nestin-Cre mice in a Mincle-dependent manner. Our further study elucidated that Mincle, Axl and TNF are involved in the pathology of Gaucher disease.

Adiponectin-cre FTO flox/flox and FTO flox/flox mouse white fat tissues

Project description:Single nucleotide polymorphisms in intron 1 of the fat mass and obesity-associated (FTO) gene were found to be associated with an increased risk of adult obesity. Enhanced FTO expression in mice leads to hyperphagia, increased fat mass, and higher body weight. Neuronal-specific FTOâ??deleted mice have an identical lean body weight phenotype to global FTO-deleted mice. The physiological role of adipose FTO in the homeostasis of energy regulation remains to be elucidated. We used microarrays to elucidate the metabolic pathways that are regulated by FTO in the white fat. FTO flox/flox and Adiponectin-cre FTO flox/flox (AFO) mice were fed with chow diet. White fat tissues from epididymal adipose pad were harvested under ad lib condition for RNA isolation. Three independent pools of FTO flox/flox and AFO mouse white fat RNA were included in the study.

RNA-seq analysis of synovial fibroblasts isolated from Ets1-flox/flox and Col6a1-Cre-Ets1-flox/flox mice of serum transfer-induced arthritis (STIA)

Project description:Synovial fibroblasts critically contribute to the pathogenesis of rheumatoid arthritis (RA) by acquiring either a pro-inflammatory or tissue-destructive phenotype. To explore the molecular mechanisms underlying the tissue-destructive fibroblast phenotype in arthritis, we performed bulk RNA-sequencing analysis on the synovial fibroblasts which were isolated from Col6a1-Cre-Ets1-flox/flox (Ets1ΔFib) and Ets1-flox/flox (Ets1flox) mice.

Gene expression of brain cells from wild type and Gba flox/flox; Nestin-Cre mice

Project description:To investigate neuronopathic Gaucher disease brain cell gene expression, we established Gba flox/flox; Nestin-Cre mice and performed scRNA sequencing of whole brain cells from these and wild type mice. Unbiased clustering analysis revealed that most remarkable change between wild type and Gba flox/flox; Nestin-Cre mice was the appearance of an activated microglia cluster, which exclusively expressed Tnf. Our further study elucidated the mechanism by which activated microglia and TNF contribute to Gaucher disease pathology.

An Auts2-Containing RNA-Binding Complex Regulates Transcript Expression in Developing Cerebral Cortex

Project description:Molecular functions of the intellectual disability syndrome gene AUTS2 remain uncertain. Two mechanisms of Auts2 function have been proposed. One study found that Auts2 modifies Polycomb repressive complex 1 (PRC1) to activate transcription of target neurodevelopmental genes by recruiting EP300, a histone acetyltransferase. A second study found that cytoplasmic AUTS2 regulates cytoskeletal assembly through PREX1 to promote neurite outgrowth and migration. To further investigate Auts2 functions, we screened for AUTS2 interactors in cerebral cortex, and profiled changes of transcript expression in the developing cortex of Auts2 conditional mutant mice. AUTS2 immunoprecipitation experiments identified interactions with proteins involved in pre-mRNA processing, and mRNAs, including those encoding EP300 and PREX1, both bound by AUTS2-containing complexes and dysregulated in Auts2 mutant cortex. We propose that AUTS2 interacts with an RNA-binding complex that directly targets transcripts encoding Auts2 effectors. This mechanism provides a unifying model that accounts for previously disparate hypotheses of AUTS2 functions.

AUTS2 confers transcriptional activation to PRC1 in the CNS (ChIP-Seq)

Project description:Naturally occurring variations of Polycomb Repressive Complex 1 (PRC1) comprise a core assembly of Polycomb group proteins and additional factors that include, surprisingly, Autism Susceptibility Candidate 2 (AUTS2). While AUTS2 is often disrupted in patients with neuronal disorders, the underlying mechanism is unclear. We investigated the role of AUTS2 as part of a previously identified PRC1 complex (PRC1-AUTS2), and in the context of neurodevelopment. In contrast to the canonical role of PRC1 in gene repression, PRC1-AUTS2 activates transcription. Biochemical studies demonstrate that the CK2 component of PRC1-AUTS2 thwarts PRC1 repressive activity and AUTS2-mediated recruitment of P300 leads to gene activation. ChIP-seq of AUTS2 shows that it regulates neuronal gene expression through promoter association. Conditional CNS targeting of Auts2 in a mouse model leads to various developmental defects. These findings reveal a natural means of subverting PRC1 activity, linking key epigenetic modulators with neuronal functions and diseases.
