Project description:Splicing factor ZRSR1 is known to have a role in spermatogenesis and fertility, leading its mutation to several reproductive defects in male. To investigate if Zrsr1 gene is involved in male reproductive control by the hypothalamus, we performed RNA-seq to determine the differences in gene expression, usage of isoforms and alternative splicing between the hypothalamus of WT mice and from Zrsr1mu mice.
Project description:We determined genomic binding of HDAC3 in mouse hypothalamus by ChIP-seq, and identified target genes of the NCOR/HDAC3 complex in hypothalamus of NS-DADm (mutated deacetylase activation domain in NCORs) mice by RNA-seq.
Project description:To uncover the cellular architecture of the mouse ventromedial hypothalamus (VMH), we used single nucleus RNA-seq (snRNA-seq) from wild-type mice.
Project description:Wolfram syndrome is caused by mutations in the WFS1 gene. WFS1 protein dysfunction results in a range of neuroendocrine syndromes and is mostly characterized by juvenile-onset diabetes mellitus and optic atrophy. WFS1 has been shown to participate in membrane trafficking, protein processing and Ca2+ homeostasis in the endoplasmic reticulum. In the present study we aimed to find the transcriptomic changes influenced by Wfs1 in the hypothalamus and hippocampus using RNA-sequencing. We used WFS1-deficient mice as a model system to analyze the changes in transcriptional networks. The number of differentially expressed genes between hypothalami of WFS1-deficient (Wfs1KO) and wild-type (WT) mice was 43 and between hippocampi 311 with False Discovery Rate (FDR) <0.05. In hypothalamus of Wfs1KO mice one of the most upregulated genes was Avpr1a whilst Avpr1b was significantly upregulated in hippocampus. Trpm8 was the most upregulated gene in the hippocampus of Wfs1KO mice. The functional analysis revealed significant enrichment of networks and pathways associated with protein synthesis, cell-to-cell signaling and interaction, molecular transport, metabolic disease and nervous system development and function. In conclusion, the transcriptomic profiles of WFS1-deficient hypothalamus and hippocampus do indicate the activation of degenerative molecular pathways causing the clinical occurrences typical to Wolfram syndrome.
Project description:We generated a single nuclei RNA-seq (snRNA-seq) dataset derived from the postnatal hypothalamus of CRH-IRESCre (CRH-Cre) mice using a retrograde Connect-seq approach.
