          Abstract

          [Purpose] The aim of this study was to investigate the change in the arteriosclerosis adhesion molecules after a healthy life exercise program that included aerobic training, anaerobic training, and traditional Korean dance. [Subjects] The subjects were 20 elderly women who were over 65 years of age and had 30% body fat. [Methods] The experimental group underwent a 12-week healthy life exercise program. To evaluate the effects of the healthy life exercise program, measurements were performed before and after the healthy life exercise program in all the subjects. [Results] After the healthy life exercise program, MCP-1 and the arteriosclerosis adhesion molecules sE-selectin and sVCAM-1 were statistically significantly decreased. [Conclusion] The 12-week healthy life exercise program reduced the levels of arteriosclerosis adhesion molecules. Therefore, the results of our study suggest that a healthy life exercise program may be useful in preventing arteriosclerosis and improving quality of life in elderly obese women.

          Weight loss reduces C-reactive protein levels in obese postmenopausal women.

          C-reactive protein (CRP) has been proposed as an independent risk factor for cardiovascular disease and has been positively associated with body weight and body fatness. We examined the hypothesis that weight loss would reduce plasma CRP levels in obese postmenopausal women. In a sample of 61 obese (body mass index, 35.6 +/- 5.0 kg/m(2)), postmenopausal women (age, 56.4 +/- 5.2 years), we found that plasma CRP levels were positively associated with dual x-ray absorptiometry-measured total body fatness (r=0.36, P<0.005) and CT-measured intra-abdominal body fat area (r=0.30, P<0.02). Significant correlations were also found between plasma CRP and triglyceride levels (r=0.33, P<0.009) and glucose disposal measured by the hyperinsulinemic-euglycemic clamp technique (r=-0.29, P<0.03). Twenty-five of the 61 women tested at baseline completed a weight loss protocol. The average weight loss was 14.5 +/- 6.2 kg (-15.6%, P<0.0001), with losses of 10.4 +/- 5.4 kg fat mass (-25.0%, P<0.0001) and 2.8 +/- 1.4 kg fat-free mass (-6.0%, P<0.0001). Visceral and subcutaneous fat areas were reduced by -36.4% and -23.7%, respectively (P<0.0001). Plasma CRP levels were significantly reduced by weight loss: average -32.3%, from 3.06 (+0.69, -1.29) to 1.63 (+0.70, -0.75) microgram/mL (P<0.0001, medians and interquartile differences). Changes in body weight and in total body fat mass were both positively associated with plasma CRP level reductions. Adiposity was a significant predictor of plasma CRP in postmenopausal women on a cross-sectional basis. Moreover, caloric restriction-induced weight loss decreased plasma CRP levels. Weight loss may represent an important intervention to reduce CRP levels, which may mediate part of its cardioprotective effects in obese postmenopausal women.

            Chemokines control fat accumulation and leptin secretion by cultured human adipocytes.

            In addition to their role in inflammation, cytokines like TNFalpha have been reported to regulate the adipose tissue function suggesting a role for these soluble mediators in metabolism. However, it is not known whether adipocytes have the capacity to secrete chemokines, a group of low molecular weight inflammatory mediators that control leukocyte migration into tissues. Here we show that primary cultures of human preadipocytes constitutively produce three chemokines, interleukin-8 (IL-8), macrophage inflammatory protein-1alpha (MIP-1alpha) and monocyte chemotactic protein-1 (MCP-1), while their level of expression is low in mature adipocytes. Upon TNFalpha treatment, the expression of all the three chemokines is upregulated in adipocytes differentiated in vitro. In addition, we describe the presence of seven different chemokine receptors, mainly in mature adipocytes, both in vitro and in human fat tissue sections. Prolonged stimulation of cultured human adipocytes with exogenous chemokines leads to a decrease in lipid content in association with the downregulation of PPARgamma mRNA expression. Moreover, chemokines positively control the secretion of leptin, a hormone that regulates appetite, by a post-transcriptional mechanism. These findings reveal a new role for chemokines in the regulation of adipose tissue and suggest a novel therapeutic basis for the treatment of obesity, diabetes and cachexia.

              Association among plasma levels of monocyte chemoattractant protein-1, traditional cardiovascular risk factors, and subclinical atherosclerosis.

              We sought to evaluate the association between plasma levels of monocyte chemoattractant protein (MCP)-1 and the risk for subclinical atherosclerosis. Monocyte chemoattractant protein is a chemokine that recruits monocytes into the developing atheroma and may contribute to atherosclerotic disease development and progression. Plasma levels of MCP-1 are independently associated with prognosis in patients with acute coronary syndromes, but few population-based data are available from subjects in earlier stages of atherosclerosis. In the Dallas Heart Study, a population-based probability sample of adults in Dallas County /=10) for subjects in the second, third, and fourth quartiles were 1.30 (95% confidence interval [CI] 0.99 to 1.73), 1.60 (95% CI 1.22 to 2.11), and 2.02 (95% CI 1.54 to 2.63), respectively. The association between MCP-1 and CAC remained significant when adjusted for traditional cardiovascular risk factors, but not when further adjusted for age. In a large population-based sample, plasma levels of MCP-1 were associated with traditional risk factors for atherosclerosis, supporting the hypothesis that MCP-1 may mediate some of the atherogenic effects of these risk factors. These findings support the potential role of MCP-1 as a biomarker target for drug development.
