Research Abstract

To clarify the mechanism by which obesity results in downregulation of Adiponectin (Ad) gene, we first tried to identify the promoter region of the Ad gene that confers the response to obesity and its responsible transcription factor(s) by using a combination of functional promoter studies and electrophoretic mobility shift assays (EMSAs) techniques in hypertrophic adipocytes model in vitro. We identified one such promoter region, which we named Diabetes/obesity-Related Element (DRE), and its binding protein(s) (Dre binding protein; Deb). Deb1 gene turned out to be a KLF family transcription factor by yeast one-hybrid screen.
EMSAs and chromatin immunoprecipitation assays revealed that Deb1 indeed bound to DRE. Deb1 dose-dependently and specifically enhanced Ad promoter activity. Regulation of Ad transcription by Deb1 was confirmed by corresponding changes in endogenous Ad mRNA by Deb1 siRNA and Deb1 overexpression in vitro. Targeted disruption of Deb1 caused a partial but significant r eduction of Ad expression in WAT and plasma Ad levels. Interestingly, expression of Deb1 and its binding to DRE were reduced in obese mice such as ob/ob mice. Moreover, we found that increased oxidative stress and inflammation as well as changes in hormonal receptor signalling observed within hypertrophic adipocytes reduced Deb1 and Ad, and that normalization of these intracellular alterations increased Deb1 and Ad.
Taken together, these results suggested that 1) obesity decreases Deb1 via multiple pathways such as oxidative stress and inflammation, which leads to Ad reduction, 2) Deb1 activators in WAT may provide a novel treatment modality for metabolic syndrome (manuscript in preparation).
Moreover, we showed that not only plasma adiponectin levels but also expression levels of AdipoR1/R2 were decreased in obesity, which appeared to play causal roles in the development of insulin resistance. Furthermore, we showed that not only agonism of AdipoR1/R2 but also strategies to increase AdipoR1/R2 in the presence of adiponectin indeed resulted in amelioration of insulin resistance and type 2 diabetes (Nat. Med. 13:332,2007).
