The circulating level of the inflammatory cytokine interleukin (IL)-6 is elevated in various insulin-resistant states including type 2 diabetes, obesity, cancer, and HIV-associated lipodystrophy. To determine the role of IL-6 in the development of insulin resistance, we examined the effects of IL-6 treatment on whole-body insulin action and glucose(More)

Low or absent expression of the cyclin-dependent kinase inhibitor p27(Kip1) serves as an excellent malignant marker for prostate and other human cancers. The level of p27(Kip1) is regulated primarily by the ubiquitin E3 ligase SCF(SKP2) through ubiquitin-dependent proteolysis. Expression of the F-box protein SKP2 is inversely correlated with p27 in many(More)
OBJECTIVE Patients with diabetes often have dyslipidemia and increased postprandial lipidmia. Induction of diabetes in LDL receptor (Ldlr(-/-)) knockout mice also leads to marked dyslipidemia. The reasons for this are unclear. RESEARCH DESIGN AND METHODS We placed Ldlr(-/-) and heterozygous LDL receptor knockout (Ldlr(+/-)) mice on a high-cholesterol(More)
Uncoupling protein 1 (UCP1) is highly expressed in brown adipose tissue, where it generates heat by uncoupling electron transport from ATP production. UCP1 is also found outside classical brown adipose tissue depots, in adipocytes that are termed 'brite' (brown-in-white) or 'beige'. In humans, the presence of brite or beige (brite/beige) adipocytes is(More)
Obese, insulin-resistant states are characterized by a paradoxical pathogenic condition in which the liver appears to be selectively insulin resistant. Specifically, insulin fails to suppress glucose production, yet successfully stimulates de novo lipogenesis. The mechanisms underlying this dysregulation remain controversial. Here, we hypothesized that(More)
The most energy-requiring organ in the body, the cardiac muscle, relies primarily on lipoprotein-derived fatty acids. Prenatal loss of cardiac lipoprotein lipase (LPL) leads to hypertriglyceridemia, but no cardiac dysfunction, in young mice. Cardiac specific loss of LPL in 8-wk-old mice was produced by a 2-wk tamoxifen treatment of MerCreMer(More)
The phosphatidylinositol 3-kinase (PI3K) signaling pathway is central to the action of insulin and many growth factors. Heterozygous mutations in the gene encoding the p85α regulatory subunit of PI3K (PIK3R1) have been identified in patients with SHORT syndrome - a disorder characterized by short stature, partial lipodystrophy, and insulin resistance. Here,(More)
