Diet-induced insulin resistance in mice lacking adiponectin/ACRP30

Here we investigated the biological functions of adiponectin/ACRP30, a fat-derived hormone, by disrupting the gene that encodes it in mice. Adiponectin/ACRP30-knockout (KO) mice showed delayed clearance of free fatty acid in plasma, low levels of fatty-acid transport protein 1 (FATP-1) mRNA in muscle, high levels of tumor necrosis factor-alpha (TNF-alpha) mRNA in adipose tissue and high plasma TNF-alpha concentrations. The KO mice exhibited...
