Hippocampus and hypothalamus RNA-sequencing of WFS1-deficient mice [hypothalamus]

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.

Gene expression in murine amygdala, cortex, hippocampus and hypothalamus of Pianp-deficient mice

Project description:Pianp (also known as Leda-1) is a type I transmembrane protein with preferential expression in the mammalian central nervous system. We used microarrays to analyze the programme of gene expression in murine brain regions amygdala, cortex, hippocampus and hypothalamus of Pianp deficient mice.

Gene expression data from hippocampus, striatum, hypothalamus cortex, Drd2-MSNs and Drd1-MSNs in mice

Project description:Goal of the experiment: Analysis of gene expression changes in the cortex, striatum, hippocampus, hypothalamus, Drd2-MSNs and Drd1-MSNs of mice with a postnatal, neuron-specific ablation of GLP or G9a as compared to control mice. For microarray analysis, hippocampus, hypothalamus, cortex and striatum of Camk2a-Cre; GLPfl/fl, Camk2a-Cre; G9afl/fl and age (10-14 week old) and sex matched littermate controls were used for total RNA purification. Four biological replicates were performed for each experiment. Polyribosome associated mRNAs from five, age (10-14 week old) and sex matched Drd1-Cre; Drd1-bacTRAP; G9afl/fl, or Drd2-Cre; Drd2-bacTRAP; G9afl/fl and Drd1-bacTRAP; G9afl/fl or Drd2-bacTRAP; G9afl/fl control mice were used. Three biological replicates were performed for each experiment.
