Transcription profiling of mouse white adipose tissue from PPARb/d knockout


ABSTRACT: Analysis of white adipose tissue of PPARb/d knockout mice. Data may point towards putative target genes of PPARb/d and thus the function of PPARb/d in white adipose tissue. Datasets were used to identify glycogen synthase 2 as novel PPAR target. Experiment Overall Design: Three month old male PPARb/d knock-out mice were on a mixed background (Sv129/C57BL/6). Wild-type littermates served as control animals. Animals received standard chow. Epididymal white adipose tissue (WAT) was removed and total RNA was isolated and pooled afterwards (five animals per group). Pooled RNA was hybridized to Affymetrix mouse genome 430 2.0 arrays arrays. Five microgram total RNA was labeled according to the ENZO-protocol, fragmented and hybridized according to Affymetrix protocols.

Glycogen synthase 2 (Gys-2) is the ratelimiting enzyme in the storage of glycogen in liver and adipose tissue, yet little is known about regulation of Gys-2 transcription. The peroxisome proliferator-activated receptors (PPARs) are transcription factors involved in the regulation of lipid and glucose metabolism and might be hypothesized to govern glycogen synthesis as well. Here, we show that Gys-2 is a direct target gene of PPARalpha, PPARbeta/delta and PPARgamma. Expression of Gys-2 is signifi  ...[more]
