Project description:We performed RNaseq of liver, hypothalamus and vomeronasal organ crosses between inbred stains of M. m. domesticus (strain WSB/EiJ) and M. m. musculus (PWD/PhJ). We also sequenced RNA from the same tissues from parental M. m. musculus (PWD/PhJ).

Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility. Gene expression was measured in whole testis from males aged 62-86 days. Samples include 190 first generation lab-bred male offspring of wild-caught mice from the Mus musculus musculus - M. m. domesticus hybrid zone.

Project description:Analysis of gene expression profiles is an attractive method for discovering how animals respond to environmental challenges in nature. Compared to low altitudes, high altitudes are characterized by reduced partial pressures of oxygen (hypoxia) and cooler ambient temperatures To better understand how mammals cope with high altitudes, we trapped wild house mice (Mus musculus domesticus) from 3 populations in La Paz, Bolivia (3000 - 3600 m) and 3 populations in Lima, Peru (0 – 200 m). Affymetrix GeneChip® Mouse Genome 430 2.0 Arrays were use to measure mRNA abundance in the livers of these 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:These arrays contain data from hypthalamus tissue of nestin-Pex5 -/- male mice Gene expression in biological replicates from hypothalamus of 4 wild type mice was compared with 4 NestinPex5-/- mice. In the latter, functional peroxisomes were deleted from all neural cells.

Project description:Brain-derived serotonin favors appetite in mice following its binding to the Htr1a and Htr2b receptors in arcuate neurons of the hypothalamus. In this study, we identified that CREB is the transcriptional effector of brain-derived serotonin control of appetite in arcuate nuclei. In this dataset, we identified the downstream genes of CREB in arcuate neurons of the hypothalamus controling appetite. We isolated hypothalami of wild type and Creb-pomcCre-/- (deleted for Creb selectively in arcuate neurons of the hypothalamus) mice and performed microarray experiments.

Project description:The hypothalamus is the brain region that regulates systemic body metabolism and multiple functions in other brain regions. In adult mice, the hypothalamus harbors neural stem/precursor cell (NSC)-like cells. Along with the dysregulation of body metabolism and physiology that occurs during aging, the NSC population in the hypothalamus declines with age. Here, we introduce a novel protocol that yields scalable and storable hypothalamus-specific NSCs (htNSCs) from hypothalamus-like organoids derived from human pluripotent stem cells (hPSCs). Implanting htNSCs into the medio-basal hypothalami of aged mice conspicuously ameliorated age-related declines in metabolic fitness, physical capacity, and cognitive function and produced corresponding histologic changes in various body tissues. Single transcriptome and immunohistochemical analyses of the grafted hypothalamic tissues showed that the anti-aging effects were attained by correcting glial NF-κB, TNFα, and NLRP3 inflammasome pathways. Collectively, our findings support the potential of anti- or healthy aging therapies that target htNSCs and hypothalamic inflammation.
