Skeletal muscle insulin signaling defects downstream of phosphatidylinositol 3-kinase at the level of Akt are associated with impaired nonoxidative glucose disposal in HIV lipodystrophy.
More than 40% of HIV-infected patients on highly active antiretroviral therapy (HAART) experience fat redistribution (lipodystrophy), a syndrome associated with insulin resistance primarily affecting insulin-stimulated nonoxidative glucose metabolism (NOGM(ins)). Skeletal muscle biopsies, obtained from 18 lipodystrophic nondiabetic patients (LIPO) and 18 nondiabetic patients without lipodystrop...
متن کاملInhalation of insulin (Exubera) is associated with augmented disposal of portally infused glucose in dogs.
The results of the present study, using the conscious beagle dog, demonstrate that inhaled insulin (INH; Exubera) provides better glycemic control during an intraportal glucose load than identical insulin levels induced by insulin (Humulin) infusion into the inferior vena cava (IVC). In the INH group (n = 13), portal glucose infusion caused arterial plasma glucose to rise transiently (152 +/- 9...
متن کاملIron Metabolism Is Associated With Adipocyte Insulin Resistance and Plasma Adiponectin
OBJECTIVE Adipocyte insulin resistance (IR) is a key feature early in the pathogenesis of type 2 diabetes mellitus (T2DM), and although scarce, data in the literature suggest a direct role for iron and iron metabolism-related factors in adipose tissue function and metabolism. Serum ferritin and transferrin were shown to be associated with muscle insulin resistance (IR) and T2DM, but little is k...
متن کاملAdiponectin is associated with vascular function independent of insulin sensitivity.
OBJECTIVE Adiponectin has been proposed to play important roles in the regulation of energy homeostasis and insulin sensitivity. In experimental studies, adiponectin has also been found to inhibit vascular smooth muscle cell proliferation. Decreased adiponectin levels have been described in patients with coronary artery disease, and circulating adiponectin predicts cardiovascular death in patie...
متن کاملReduced insulin-stimulated glucose transport in denervated muscle is associated with impaired Akt-alpha activation.
Insulin signaling was examined in muscle made insulin resistant by short-term (24-h) denervation. Insulin-stimulated glucose transport in vitro was reduced by 28% (P < 0.05) in denervated muscle (DEN). In control muscle (SHAM), insulin increased levels of surface-detectable GLUT-4 (i.e., translocated GLUT-4) 1.8-fold (P < 0.05), whereas DEN surface GLUT-4 was not increased by insulin (P > 0.05)...
