Genome-wide analysis of gene expression changes in mouse subcutaneous adipose tissue in cold compared to thermal neutrality
Ontology highlight
ABSTRACT: Comparison of gene expression pattern of subcutaneous adipose tissue from mice housed in cold (6-degree Celsius) or in thermal neutrality (30-degree celsius).Verify canonical white adipose tissue beiging pathways and genes that are regulated by cold-exposure as well as identify gap junction genes that are regulated by cold in white adipoes tissue. Total RNA obtained from mouse subcutaneous tissue from mice house at two different temperature; RNA extracted from 3-4 mice was pooled into one sample.

Project description:Male ferrets, aged 3 months, were divided into two group: one group remained at 22 degrees Celsius, while the other group was acclimatized to 4 degrees Celsius for one week. After sacrification, inguinal and periaortic white adipose tissues were dissected, and used for RNA isolation and subsequent global gene expression profiling using custom Agilent ferret-specific 2x400K microarrays. Data analysis indicated that while the cold exposure induces an increase on metabolism in inguinal white adopose tissue, in periaortic white adipose tissue this stimulus induces a reduction on expression of genes involved in cell cycle and in immune response.
Project description:We run microarrays from three per group Sv129 female mice, ten weeks old, which were maintained at 28M-BM-0C (warm conditions) or 6M-BM-0 C (cold stimulated) for ten days, while standard animal house temperature is 22 M-BM-0C. After ten days, three types of tissue were collected: Brown Adipose Tissue (BAT), Mesenteric (visceral) White Adipose Tissue (MES) and Posterior Subcutaneous White Adipose Tissue (WAT) Different adipose tissue depots were taken for RNA extraction and hybridization on Affymetrix microarrays. We sought to determine the differences between white and brown adipose tissues at different temperatures
Project description:Male ferrets, aged 3 months, were divided into two group: one group remained at 22 degrees Celsius, while the other group was acclimatized to 4 degrees Celsius for one week. After sacrification, inguinal and periaortic white adipose tissues were dissected, and peripheral blood mononuclear cells (PBMC) were isolated. The three tissues are used for RNA isolation and subsequent global gene expression profiling using custom Agilent ferret-specific 2x400K microarrays. Data analysis indicated that the cold exposure induce a clear gene expression response of some genes in the inguinal and periaortic white adipose tissue as in PBMC. These genes could be defined as a biomakers of the effect of cold exposure in these cells.

Project description:mRNA expression was compared in between wild type and mitoNEET transgenic subcutaneous adipose tissue RNA was isolated from subcutaneous adipose tissue from male FVB mice in the light phase. mRNA expression was compared in between wild type and mitoNEET transgenic subcutaneous adipose tissue.
