1 The aim of this study was to determine if administration of DHEA might influence adiponectin gene expression and secretion from adipose tissue. Dehydroepiandrosterone adiponectin, C1Q and collagen domain containing Rattus norvegicus
2 We demonstrate here the inducing effect of exogenously administered DHEA on adiponectin gene expression in epididymal WAT and adiponectin levels in serum of rats fed a DHEA-containing diet (0.6%, w/w) for 2 weeks, accompanied by a reduction in epididymal adipose tissue mass. Dehydroepiandrosterone adiponectin, C1Q and collagen domain containing Rattus norvegicus

Dehydroepiandrosterone adiponectin, C1Q and collagen domain containing Rattus norvegicus
4 A corresponding increase in peroxisome proliferator-activated receptor gamma (PPAR(gamma)) mRNA expression suggests that PPAR(gamma) may be involved in the up-regulation of adiponectin gene expression after DHEA treatment. Dehydroepiandrosterone adiponectin, C1Q and collagen domain containing Rattus norvegicus
5 The presented observations indicate that the positive effects of DHEA, which seems to play a protective role against insulin resistance and atherosclerosis, may be in fact indirect and due to up-regulation of adiponectin gene expression and stimulation of adiponectin secretion from adipose tissue. Dehydroepiandrosterone adiponectin, C1Q and collagen domain containing Rattus norvegicus
