Summary: We identified secreted frizzled-related protein-5 (Sfrp5) as a transcript that is upregulated during adipocyte differentiation and that is increased in white adipose tissue (WAT) of obese mice, compared to lean mice. To investigate the function of sFRP5 in adipose tissue biology, we studied sFRP5Q27stop mice, in which ENU mutagenesis was used to create a premature stop codon at Gln27, thereby creating a likely null allele. Male wild-type or Sfrp5 KO (Q27Stop) mice were fed a high-fat diet from the ages of four weeks to twelve weeks. At twelve weeks of age, mice were euthanized. Total RNA was then isolated from gonadal WAT and RNA was analyzed by Affymetrix microarrays. Seven wild-type and eight Sfrp5 KO mice were used.

Summary: To investigate the gene expression change in the white adipose tissue (WAT) of patDp/+ mice compared with wild type mice, the whole genome microarray profiling was performed. Total RNA from WAT of young adult stage mice (9-10 weeks old) was extracted and subject to microarray analysis. Expression change of sfrp5 gene was further validated by real-time PCR, suggesting this gene might contribute to the obesity in patDp/+ mice. We measured the gene expression change in WAT of young adult stage mice. Three patDp/+ mice and three wild type mice were used in the experiment.

Summary: To explore the loss of Dullurd function in mouse embryo development, we have performed the Agilent microarray analysis between a Dullard-heterozygous and a Dullard-homozygous E7.5 embryo. Our findings show that Dullard does not act in concert with BMP4 and Smad1/5/8, whereas loss of Dullard is associated with a reduced level of WNT/beta-catenin signaling activity, accompanied by elevated expression of Wnt3 and WNT antagonists including Dkk1, Sfrp1 and Sfrp5 in mouse germ cell formation. E7.5 mouse embryos were collected. One Dullard-heterozygous embryo and one Dullard-homozygous embryo were used for the analysis.
