Title of Document: THE INFLUENCE OF VISFATIN AND VISFATIN GENE POLYMORPHISMS ON GLUCOSE AND OBESITY-RELATED VARIABLES AND THEIR RESPONSES TO AEROBIC EXERCISE TRAINING Jennifer Ann McKenzie, Ph.D., 2008 Directed By: Professor James M. Hagberg, Department of Kinesiology Adipokines, soluble factors produced by adipocytes, may help to connect diabetes and obesity; one such adipokine is visfatin. Pr...

Visfatin is a novel adipocytokine exerting insulin-mimetic effects in various insulin-sensitive tissues such as liver, muscle, and fat. In contrast, interleukin (IL)-6 is a proinflammatory adipose-secreted factor that induces insulin resistance and plasma concentrations that correlate with the development of type 2 diabetes mellitus. In the present study, the impact of IL-6 on visfatin gene exp...

BACKGROUND Henoch-Schönlein purpura (HSP) is an immune complex-mediated disease predominantly characterized by the deposition of circulating immune complexes containing immunoglobulin A (IgA) on the walls of small vessels. Although the pathogenesis of HSP is not yet fully understood, some researchers proposed that B-cell activation might play a critical role in the development of this disease. ...

OBJECTIVES The insulin-mimetic adipocytokine visfatin has been related to obesity. The aim of this study was to examine whether weight loss could change visfatin concentrations in morbidly obese patients and its relationship with insulin resistance. MATERIAL AND METHODS This was an interventional study analyzing a population of 41 morbidly obese patients. A biochemical analysis was realized b...

Adipocytokines play an important role in the pathogenesis of atherosclerosis through inflammation associated with obesity and metabolic syndrome. In many studies, visfatin and resistin are reported as modulators of insulin sensitivity and inflammatory status in humans. Visfatin has been reported to be a beneficial adipocytokine with insulin mimicking/ sensitizing effects. In contrast, resistin ...

Introduction. Adipose tissue contributes to atherosclerosis with mechanisms related to adipokine secretion. Polyphenols may exhibit antiatherogenic properties. The aim of the study was to investigate the effects of three polyphenols, namely, quercetin, epigallocatechin gallate (EGCG), and resveratrol on adipokine secretion from cultured human adipocytes. Methods. Human SGBS adipocytes were trea...

AIM/BACKGROUND Experimental and clinical studies revealed contradictory data concerning the influence of renin-angiotensin-aldosterone (RAA) system activation on visfatin release. The aim of the present study was the assessment of the effect of dietary sodium restriction with RAA system activation on visfatin level in hypertensive and normotensive patients with visceral obesity. METHODS The s...

Background: Metabolic syndrome (MS) and non-alcoholic fatty liver disease (NAFLD) is a common public health problem. Visfatin is secreted by visceral adipose tissue and is an adipocytokine. It could be a pro-inflammatory adipocytokine and is related to the metabolic syndrome and non-alcoholic fatty liver disease. This study evaluated the association between visfatin levels in patients w...

OBJECTIVE Adipose tissue dysfunction, characterized by dysregulation of adipokines production and/or secretion, has been implicated in the pathophysiology of type-2 diabetes mellitus, a metabolic complication closely related to gestational diabetes mellitus (GDM). Recently, an association between circulating maternal visfatin, a novel adipokine with metabolic and immunoregulatory properties, an...

Psoriasis is a chronic, autoimmune, and inflammatory disease of unknown etiology, characterized by T lymphocyte mediated keratinocyte proliferation. In recent years the relationship between psoriasis and adipose tissue cytokines has been reported. Psoriasis as a triggering factor for the immune and metabolic disorders can be associated with diabetes mellitus, abnormal lipid metabolism, and meta...
