Abdominal fat accumulation has been shown to play crucial roles in the development of metabolic syndrome. Visceral fat accumulation particularly is closely correlated to the development of cardiovascular disease and obesity-related disorders such as diabetes mellitus, hyperlipidemia and hypertension. Given these clinical findings, the functions of adipocytes have been intensively investigated in the past 10 years, and have been revealed to act as endocrine cells that secrete various bioactive substances termed adipocytokines. Among adipocytokines, tumor-necrosis factor-alpha, plasminogen activator inhibitor type 1 and heparin-binding epidermal growth factor-like growth factor are produced in adipocytes as well as other organs, and contribute to the development of vascular diseases. Visfatin has been identified as a visceral-fat-specific protein that might be involved in the development of obesity-related diseases, such as diabetes mellitus and cardiovascular disease. In contrast to these adipocytokines, adiponectin, which is an adipose-tissue-specific, collagen-like protein, has been noted as an important antiatherogenic and antidiabetic protein, or as an anti-inflammatory protein. The functions of adipocytokine secretion might be regulated dynamically by nutritional state. Visceral fat accumulation causes dysregulation of adipocyte functions, including oversecretion of tumor-necrosis factor-alpha, plasminogen activator inhibitor type 1 and heparin-binding epidermal growth factor-like growth factor, and hyposecretion of adiponectin, which results in the development of a variety of metabolic and circulatory diseases. In this review, the importance of adipocytokines, particularly adiponectin, is discussed with respect to cardiovascular diseases.

Prostate cancer, the third most common cancer in men worldwide, varies substantially according to geographic region and race/ethnicity. Obesity and associated endocrine variation are foremost among the risk factors that may underlie these regional and ethnic differences. The association between obesity and prostate cancer incidence is complex and has yielded inconsistent results. Studies that have linked obesity with prostate cancer mortality, advanced stage disease, and higher grade Gleason score, however, have produced more consistent findings, indicating that obesity may not necessarily increase the risk of prostate cancer, but may promote it once established. Additionally, metabolic syndrome, which includes disturbed glucose metabolism and insulin bioactivity, may also be associated with prostate carcinogenesis. Adipokines, defined as biologically active polypeptides produced by adipose tissue, have been linked with a number of carcinogenic mechanisms, including angiogenesis, cell proliferation, metastasis, and alterations in sex-steroid hormone levels. A number of emerging studies have implicated the role of adipokines in prostate carcinogenesis. This review explores the specific roles of several adipokines as putative mediating factors between obesity and prostate cancer with particular attention to leptin, interleukin-6 (IL-6), heparin-binding epidermal growth factor-like growth factor (HB-EGF), vascular endothelial growth factor (VEGF) and adiponectin.

Metabolic syndrome is a highly atherogenic state in which hyperglycemia, dyslipidemia and hypertension cluster in one individual. Intra-abdominal visceral fat accumulation plays a key role in the development of these disorders and the occurrence of metabolic syndrome. We have investigated adipocyte functions intensively in the past 10 years and have revealed that these cells act as endocrine cells secreting a variety of bioactive substances, termed adipocytokines. Among adipocytokines, tumor necrosis factor-alpha, plasminogen activator inhibitor type 1 and heparin-binding epidermal growth factor-like growth factor are produced in adipocytes as well as other organs and may contribute to the development of vascular diseases. Visfatin was identified recently as a visceral-fat-specific protein that might be involved in the development of obesity-related diseases, such as diabetes mellitus and cardiovascular disease. In contrast to these adipocytokines, adiponectin, an adipose tissue-specific, collagen-like protein, has been noted as an important antiatherogenic and antidiabetic protein or as an anti-inflammatory protein. The functions of adipocytokine secretion might be regulated dynamically by nutritional state. Visceral fat accumulation causes dysregulation of adipocyte functions, including oversecretion of tumor necrosis factor-alpha, plasminogen activator inhibitor type 1, heparin-binding epidermal growth factor-like growth factor and visfatin and hyposecretion of adiponectin simultaneously, which results in the development of a variety of metabolic and circulatory diseases. In this article, the importance of adipocytokines, focusing particularly on adiponectin, is discussed with respect to lifestyle-related diseases, such as diabetes mellitus and cardiovascular disease.

Heparin-binding EGF-like growth factor (HB-EGF) is an EGF family member that interacts with epidermal growth factor receptor (EGFR) and ERBB4. Since HB-EGF was first identified as a novel growth factor secreted from a human macrophage cell line, numerous pathological and physiological functions related to cell proliferation, migration, and inflammation have been reported. Notably, the expression of HB-EGF is sensitively upregulated by oxidative stress in the endothelial cells and functions for auto- and paracrine-EGFR signaling. Overnutrition and obesity cause elevation of HB-EGF expression and EGFR signaling in the hepatic and vascular systems. Modulations of HB-EGF signaling showed a series of protections against phenotypes related to metabolic syndrome and advanced metabolic diseases, suggesting HB-EGF as a potential target against metabolic diseases.
