Abstract

Sirtuin1 (SIRT1) is activated during calorie restriction and appears to be related to energy balance through glucose or lipid metabolism and insulin signaling. These findings suggest that SIRT1 may play a role in the pathophysiology of visceral obesity. Therefore, we investigated the relationship between SIRT1 gene expression in circulating peripheral blood mononuclear cells (PBMCs) and abdominal visceral adiposity as measured by computed tomography. We recruited 43 men and women without history of diabetes or cardiovascular disease Biomarkers of metabolic disease and body composition by computed tomography were assessed. SIRT1 gene expression was determined using isolated PBMCs. SIRT1 expression levels negatively correlated with body mass index, waist circumference, abdominal visceral fat area, and homeostasis model of assessment of insulin resistance (HOMA-IR) and positively correlated with adiponectin levels. Results of step-wise multiple regression analysis revealed that abdominal visceral fat area and HOMA-IR were independently associated with SIRT1 expression. The significant association between abdominal visceral fat accumulation and SIRT1 gene expression in PBMCs suggests that SIRT1 may be a new therapeutic target for the prevention of disease related to obesity, especially visceral obesity.
