Project description:Strain differences in gene expression in the hypothalamus of BXD recombinant inbred mice We used microarrays to evaluate genetic and sex-specific differences in gene expression in the hypothalamus
Project description:Strain differences in gene expression in the hypothalamus of BXD recombinant inbred mice We used microarrays to evaluate genetic and sex-specific differences in gene expression in the hypothalamus Hypothalamus was dissected from adult male and female mice and process for expression analysis
Project description:We profiled gene expression in hypothalamus tissue from F2 progeny from a cross between the outbred M16 (selectively bred for rapid weight gain) and ICR (control) mouse strains. We developed a framework for reconstructing tissue-to-tissue coexpression networks between genes in hypothalamus, liver or hypothalamus tissues that are independent of networks constructed from single tissue analyses. The subnetworks we identify as specific to tissue-to-tissue interactions associate with multiple obesity-relevant biological functions like circadian rhythm, energy balance, stress response, or immune response. Keywords: Tissue profiling in a mouse F2 cross. We analyzed 308 hypothalamus samples.

Project description:We used microarrays to investigate whether transcriptional dysregulation in hypothalamus is caused by expression of the huntingtin (HTT) protein We used two different Huntington's disease mouse models: BACHD mice with ubiquitous full-length mutant HTT expression (97 CAG repeats) and wild-type mice with targeted bilateral injections of wild-type or mutant HTT (853 amino acids length, wild-type HTT: 18 CAG repeats, mutant HTT: 79 CAG repeats) in hypothalamus.
