چکیده

Whereas truncal (central) adiposity is strongly associated with the insulin resistant metabolic syndrome, it is uncertain whether this is accounted for principally by visceral adiposity (VAT). Several recent studies find as strong or stronger association between subcutaneous abdominal adiposity (SAT) and insulin resistance. To reexamine the issue of truncal adipose tissue depots, we performed cross-sectional abdominal computed tomography, and we undertook the novel approach of partitioning SAT into the plane superficial to the fascia within subcutaneous adipose tissue (superficial SAT) and that below this fascia (deep SAT), as well as measurement of VAT. Among 47 lean and obese glucose-tolerant men and women, insulin-stimulated glucose utilization, measured by euglycemic clamp, was strongly correlated with both VAT and deep SAT (r = -0.61 and -0.64, respectively; both P < 0.001), but not with superficial SAT (r = -0.29, not significant). Also, VAT and deep SAT followed a highly congruent pattern of associations with glucose and insulin area under the curve (75-g oral glucose tolerance test), mean arterial blood pressure, apoprotein-B, high-density lipoprotein cholesterol, and triglyceride. Superficial SAT had markedly weaker association with all these parameters and instead followed the pattern observed for thigh subcutaneous adiposity. We conclude that there are two functionally distinct compartments of adipose tissue within abdominal subcutaneous fat and that the deep SAT has a strong relation to insulin resistance.

Association of some dietary intakes, anthropometric measurements and insulin resistance with the relative P53 gene expression in visceral and subcutaneous adipose tissue in obese, and non-obese subjects

Background and Objectives: The P53 is one of the genes involved in weight management. This study investigated associations of dietary intakes, anthropometric measurements and insulin resistance with relative P53 gene expressions.  Materials & Methods: Visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) were collected from 151 individuals, aging nearly 40 years, who underwent el...

The Association of Omentin Gene Expression in Visceral and Subcutaneous Adipose Tissues with Plasma Fatty Acids Profile and Dietary Fatty Acids

Introduction: Omentin, an adipokine, with anti-inflammatory effects reduces insulin resistance, and can hence, play an important role in prevention of cardiovascular disease and diabetes. The present study aimed to investigate the association of plasma and dietary fatty acids with gene expression of omentin in visceral and subcutaneous adipose tissues. Materials and Methods: Visceral and subcut...

Over Expression of FOXO1 in Subcutaneous Fatty Tissue and its Response to Resistance Training in High Fat Diet and Type 2 Diabetic Rat

Objective: Forkhead box proteins and Forkhead box transcription factor O1 (FOXO1) in particular, mediate insulin signaling pathways and glucose homeostasis. This study aimed to compare FOXO1 expression in subcutaneous adipose (SA) tissue between obese rats with and without type 2 diabetes (T2D) and its response to resistance training in T2D. Materials and Methods: 21 male wistar rats (220±20 g...

Body Fat Distribution and Insulin Resistance

The burden of obesity has increased globally over the last few decades and its association with insulin resistance and related cardio-metabolic problems have adversely affected our ability to reduce population morbidity and mortality. Traditionally, adipose tissue in the visceral fat depot has been considered a major culprit in the development of insulin resistance. However, there is a growing ...
