The cold exposure produce a different gene expression pattern in inguinal and periaortic white adipose. Mustela putorius furo

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. Overall design: Ferrets, male, aged 3 months, were divided into two groups: 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 immediately snap frozen in liquid nitrogen. Total RNA was isolated, quantified and qualified, and subsequently used for global gene expression profiling using custom Agilent ferret-specific 2x400K microarrays.
