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.

DNA methylation activated full-length EMX1 facilitates metastasis through EMX1-EGFR-ERK axis in hepatocellular carcinoma

Project description:Altered DNA methylation is a crucial epigenetic event in hepatocellular carcinoma (HCC) development and progression. Through methylation-transcriptomic analysis, we identified a set of sixty potential DNA methylation-based epidriver genes. This set of genes focuses on the hypermethylation of EMX1, which is frequently observed in hepatobiliary tumors. Despite of its frequent occurrence, the function of EMX1 remains largely unknown. By utilizing bisulfite-next-generation sequencing, we have detected EMX1 DNA hypermethylation on the gene body, which is positively correlated with EMX1 mRNA expression. Further analysis revealed that EMX1 mRNA terminal exon splicing in HCC generated two protein isoforms: EMX1 full length (EMX1-FL) and alternative terminal exon splicing isoform (EMX1-X1). Cellular functional assays demonstrated that gain-of-function EMX1-FL, but not EMX1-X1, induced HCC cells migration and invasion while silencing EMX1-FL inhibited HCC cells motility. This result was further validated by in vivo tumor metastasis models. Mechanistically, EMX1-FL bound to EGFR promoter, promoting EGFR transcription and activating EGFR-ERK signaling to trigger tumor metastasis. Therefore, EGFR may be a potential therapeutic target for EMX1-high expression HCC. Our work illuminated the crucial role of gene body hypermethylation-activated EMX1-FL in promoting tumorigenesis and metastasis in HCC. These findings pave the way for targeting the EMX1-EGFR axis in HCC tumorigenicity and metastasis.
