Klibansky, David A., Andrew Chin, Inga J. Duignan, and Jay M. Edelberg. Synergistic targeting with bone marrow-derived cells and PDGF improves diabetic vascular function. Am J Physiol Heart Circ Physiol 290: H1387–H1392, 2006. First published December 9, 2005; doi:10.1152/ajpheart.00652.2005.—Diabetes mellitus is associated with an increased risk of vascular disease, with significant alteration...

Dietary obesity is associated with type 2 diabetes and cardiovascular diseases, although the underlying mechanism is unknown. This study was undertaken to elucidate the role of angiotensin II and apoptosis signal regulating kinase-1 (ASK1) in obesity/diabetes-associated cardiovascular complications and hepatic steatosis. Mice fed a high-fat diet were treated with olmesartan, an angiotensin II t...

Vasohibin-1 (VASH1) is a unique endogenous inhibitor of angiogenesis that is induced in endothelial cells by pro-angiogenic factors. We previously reported renoprotective effect of adenoviral delivery of VASH1 in diabetic nephropathy model, and herein investigated the potential protective role of endogenous VASH1 by using VASH1-deficient mice. Streptozotocin-induced type 1 diabetic VASH1 hetero...

Increased expression of the facilitative glucose transporter, GLUT1, leads to glomerulopathy that resembles diabetic nephropathy, whereas prevention of enhanced GLUT1 expression retards nephropathy. While many of the GLUT1-mediated effects are likely due to mesangial cell effects, we hypothesized that increased GLUT1 expression in podocytes also contributes to the progression of diabetic nephro...

BACKGROUND Safflower extract and aceglutamide (SA) has been used clinically for the treatment of cerebrovascular diseases such as cerebral embolism, hemorrhage, and mental deterioration. This study aimed to investigate the effect and mechanism of SA injection in the recovery of peripheral innervations of diabetic mice. METHODS The C57BL/6 male mice were divided into four groups: normal contro...

Abstract Background and Aims Diabetic nephropathy (DN) is a major cause of mortality in patients with diabetes chronic kidney disease, but there lack effective therapeutic drugs for this disease. The development progression DN influenced by fibrosis. transforming growth factor (TGF)-β1 key cytokine involved fibrosis many different organ systems. Anti-fibrotic gene (Anti-F) TGF-β/Smad signaling....

Diabetes causes skin complications, including xerosis and foot ulcers. Ulcers complicated by infections exacerbate skin conditions, and in severe cases, limb/toe amputations are required to prevent the development of sepsis. Here, we hypothesize that hyperglycemia induces skin barrier dysfunction with alterations of epidermal integrity. The effects of hyperglycemia on the epidermis were examine...

We hypothesized that impaired nitric oxide (NO)-dependent dilation (endothelial dysfunction) in type 2 diabetes results, in part, from elevated production of superoxide (O(2)(*-)) induced by the interaction of advanced glycation end products (AGE)/receptor for AGE (RAGE) and TNF-alpha signaling. We assessed the role of AGE/RAGE and TNF-alpha signaling in endothelial dysfunction in type 2 diabet...

Changes in norepinephrine-induced transient contractions in Ca2+-deficient solution were investigated in the aortic smooth muscles of diabetic ALS (alloxan-induced diabetes susceptible) mice. The transient contractions in diabetic mice were significantly larger than those in normal mice. The longer incubation of the muscle preparations in Ca2+-deficient solution made the transient contractions ...

Coagulation and complement regulators belong to two interactive systems constituting emerging mechanisms of diabetic nephropathy. Thrombomodulin (TM) regulates both coagulation and complement activation, in part through discrete domains. TM's lectin like domain dampens complement activation, while its EGF-like domains independently enhance activation of the anti-coagulant and cytoprotective ser...
