The mammalian telomere-binding protein Rap1 was found to have additional non-telomeric functions, acting as a transcriptional cofactor and a regulator of the NF-kB pathway. Here, we assess the effect of disrupting mouse Rap1 in vivo, and report on its unanticipated role in metabolic regulation and body weight homeostasis. Rap1 inhibition causes dysregulation in hepatic as well as adipose function. In addition, using a separation-of-function allele, we show that the metabolic function of Rap1 is independent of its recruitment to TTAGGG binding elements found at telomeres, and at other interstitial loci.

View SamplesHere, we characterize differential expression patterns associated with two chromosomal inversions found in natural Drosophila melanogaster populations. To isolate the impacts of genome structure, we engineered synthetic chromosomal inversions on controlled genetic backgrounds with breakpoints that closely match each natural inversion.

View SamplesDifferent human adipose tissue depots may have functional differences. Subcutaneous human adipose tissue has been extensively studied, but less is known about other depots. Perithyroid (PT) adipose tissue contains not only white adipocytes but also brown adipocytes. The aim of this study was to compare the expression of brown adipocyte containing perithyroid adipose tissue with s.c. adipose tissue.role in the development of obesity. Expression profiling of adipose tissue may give insights into mechanisms contributing to obesity and obesity-related disorders.
