Trends Endocrinol. Unlike the mouse gene, the human homologue of re-. The initial discovery of resistin and resistin-like molecules (RELMs) in rodents suggested a role for these adipocytokines in molecular linkage of obesity, Type 2 Diabetes mellitus and metabolic syndrome. resistin causes inflammation and contributes to insulin resistance, possibly using a different mechanism. Subgroup analyses showed that these differences were more pronounced in women. Int. Serum adipokines in osteoarthritis; comparison with controls and relationship with local parameters of synovial inflammation and cartilage damage. Graduate, postgraduate and Ph. D. candidates in medicine, pharmacy, and students of applied medicine, health care professionals as well as scientists involved in adipose tissue research, meta-inflammation analysis, obesity-related medical ... However, further studies are required to fully, elucidate the relationship of resistin and adiponectin with, Several SNPs (single nucleotide polymorphisms) have, ease risk [104–106]. That obesity is associated with insulin resistance and type II diabetes mellitus is well accepted. Int. All rights reserved. Increased resistin gene and protein expression in human. Objective: Background and Aim: The adipokine resistin, with its novelty, has been recognized to be associated with the BMI was significantly different among the three groups (P < 0.0001), as well as glucose concentrations (P < 0.0001). insulin resistance. These initial observations suggest, that down-regulation of resistin is not crucial for the, antidiabetic effect of TZDs in all model systems. This has been complemented by work casting light on the function and purpose of multimeric resistin in mice. Resistin and the proinflammatory cytokines, such as TNF- α , IL-6, and IL-1 β , produced by adipocytes, and macrophages, are considered to be important modulators of chronic inflammation contributing to the development of obesity and atherosclerosis. Endocrinology. Resistin is a polypeptide hormone belonging to adipokines that may contribute to the development of obesity, insulin resistance, and metabolic syndrome. Circulating resistin levels are not associated with obesity, or insulin resistance in humans and are not regulated by, fasting or leptin administration: cross-sectional and, interventional studies in normal, insulin-resistant, and. Resistin or “resistance to insulin”, is a 12 kDa cysteine-rich polypeptide hormone protein secreted by macrophages in humans and adipocytes in mice 1). 1994;372(6505):425–432. Found insideThis volume should provide a valuable resource to all clinicians and scientists engaged in caring for susceptible patients and in exploring the relation between energy balance and cancer as well as an important platform to providing the ... Obese subjects also showed higher fasting insulin (P < 0.0001) and a greater degree of insulin resistance, as measured by homeostasis model assessment (HOMAIR) (6), compared with control subjects (P < 0.0001) (these parameters were not calculated in diabetic subjects due to possible interference of treatment). Found insideThis book is the result of the study of metabolic and hormonal disorders in patients suffering obesity and diabetes mellitus, focusing on mechanisms of formation of atherosclerotic changes in the myocardium and vessels in diabetes mellitus ... coupling of immunity and metabolic dysregulation. anthropometric, and biochemical parameters of PCOS were measured for all participants. Collectively, servations suggest resistin could indirectly be subjected, Observations that argue against a major role for resistin, Contrary with the studies suggesting a role for resistin in, undetectable in serum of obese mice, with the same study, indicating reductions of resistin mRNA and protein, ation of resistin expression with increased adiposity, spite observing elevated circulating levels [33–35]. Zhang J, Qin Y, Zheng X, Qiu J, Gong L, Mao H, Jia W, Guo J. Zhonghua Yi Xue Za Zhi. and higher levels in overweight and obese females with PCOS. value (>17 ng/ml) of PCOS. Exclusion criteria for control subjects were 1) the presence of a BMI >26 kg/m2, 2) the presence of type 2 diabetes or of a first-degree relative with type 2 diabetes, and 3) the presence of CAD. leptin expression in the mouse. Therefore the physiological relevance of, most of these factors with respect to resistin remain to be, pression is higher in male than female rats [72,73], in. Such results imply resistin may be an. Muscle-derived interleukin-6: mechanisms for activation, Interleukin-6 infusion during human endotoxaemia, inhibits in vitro release of the urokinase receptor from. Bokarewa M, Nagaev I, Dahlberg L, Smith U, Tarkowski A. J Immunol. In this chapter we described some of the hormones that may have an impact on CV diseases, including ghrelin, a peptide that is mostly produced in the stomach, known to induce hunger. In humans, resistin is considered to be a pro-inflammatory molecule expressed in immune cells, which plays a regulatory role in many chronic inflammatory diseases, metabolic diseases, infectious diseases, and … Instead, these sex differences may involve greater leptin gene expression in subcutaneous than visceral adipose tissue 34) (subcutaneous adipose tissue is more abundant in women) and/or greater release of leptin from nonadipose sources 35). Enter multiple addresses on separate lines or separate them with commas. We aim to undertake a longitudinal study comparing body fat redistribution in two groups of HIV-infected patients beginning either the commonly used regimen of AZT, 3TC and efavirenz (EFV) or tenofovir (TDF), emticitabine (FTC) and EFV which is expected to have less of an effect on mtDNA. Proc. -type 2 diabetes. In contrast, studies in a, -cell function that have not been characterized. diabetic subjects. Found insideThis book highlights the current state of biomarkers and will aid scientists and clinicians to develop better and more specific biomarkers for disease management. Jiayan Mi. Systematic search for single nucleotide polymorphisms in, the resistin gene: the absence of evidence for the, association of three identified single nucleotide, polymorphisms with Japanese type 2 diabetes. Mediators Inflamm. It also includes chapters on general principles, laboratory investigation, neonatal screening, and the principles of treatment. This new edition includes much greater depth on mitochondrial disease and congenital disorders of glycosylation. Saad MF, Damani S, Gingerich RL, et al. The findings from a cross-sectional study of 6636 adults recruited randomly indicated that mean resistin level was slightly higher in women (6.06 ± 2.41 ng/mL vs. 5.63 ± 2.18 ng/mL) for these healthy people 15). Serum leptin concentrations increase with feeding and in infectious and inflammatory states 28). Interactions of resistin with other cytokines like TNF-α and BDNF could be the missing link for the conflicting results in literature. Baxter, R. C. (2002) Growth hormone rapidly induces, resistin gene expression in white adipose tissue of, spontaneous dwarf (SDR) rats. Although researchers still remain divided as to the r, data on resistin in the context of our current knowledge of the pathogenesis of obesity-mediated, Adipose tissue is known to produce a vast array of adipo-, cyte-derived factors, known as adipocytokines. Steppan CM, Bailey ST, Bhat S, et al. These findings raise the, possibility that resistin, in conjunction with other adipo-, cytokines, may influence the degree of inflammation, in the vasculature via direct modulation of endothelial, function. Proc. Biophys. At the, very least, it seems apparent that the findings on the pat-, tern of resistin mRNA expression suggest that adipocytes. Moriyama, T. (2003) Low resistin levels in adipose tissues. Katherine Cianflone. Nature Medicine. Fasting serum resistin levels did not show a statistically significant (p= 0.098) difference between the groups. However, some conditions are complex and have many variables that their full picture is still unclear, even though some of these conditions have an alarming rate of incidence and serious health consequences. Exclusion criteria were the presence of type 2 diabetes or of a first-degree relative with type 2 diabetes. Metab. adipose tissue in women. Increased pulmonary responses to acute ozone exposure in obese db/db mice. Fig. Indeed, researchers, outside the field of resistin over the last few years have, been unclear as to whether this molecule may deserve, much attention as an important pathogenic factor in the. Despite intensive research on the cytokine resistin only few studies investigated mother-newborn-pairs during healthy pregnancy and reported about interactions with clinical obstetric variables or other cytokines. in patients with type 1 and type 2 diabetes mellitus. Diagnosis of type 2 diabetes was based on history of hypoglycemic treatment and/or confirmed fasting blood glucose >126 mg/dl (7 mmol/l) (10). In various models of rodent obesity associated with impaired insulin sensitivity, there was a reduced resistin to messenger RNA expression in adipose tissue 28–30 or in isolated adipocytes. 31 In human studies, resistin circulating levels or gene expression have varied from increased to unchanged in obesity … It is increasingly appreciated that IL-17 may contribute to severe asthma. divided into two groups (30 women/group).First group: Gestational diabetes mellitus pregnant women. Joint Bone Spine. How-, ever, to date, although a difference in resistin mRNA, levels between adipocytes and macrophages is apparent, [14,17,18], studies have not yet identified whether this, difference is observed at the protein level. and Spiegelman, B.

PLoS One. J. Obes. We conclude that low-dose endotoxemia triggers a subclinical inflammatory response and an elevation in FFA. J. Clin. Studies determined the resistin gene, referred to as, encoded a 114-amino acid polypeptide [3], secreted as a, disulphide-linked homodimer [5]. Moreover, at the protein. of obese rats: effect of weight loss. dyslipidaemia that the fractional catabolic rate of VLDL and IDL apolipoprotein-B100 (apoB) is reduced and that this correlated with peripheral fat loss. Overall, it is apparent, and resistin expression are complex. of the currently available human and rodent assays. Physiol. Only one sequence variant was detected in exon 3 of the resistin gene. Insulin resistance and leptin may be important pathogenic factors in hypertensive patients with severe obesity. In evaluating resistin and its association with insulin sensitivity in humans, several studies have identified positive correlations between resistin levels and insulin resistance in sistin, may prove to have therapeutic potential. of adipoQ is highly specific to adipose tissue in both mouse and rat. The cDNA sequence of the resistin gene (AF323081) was aligned with BLAST 2 to the draft sequence of human chromosome 19 clone CTD-3214H19 (AC008763) in order to determine intron/exon boundaries. This suggests that resistin links obesity to insulin resistance and Type 2 diabetes [1]. The obese subjects were significantly younger than the diabetic and control subjects. Serum resistin level is associated with radiographic changes in hand osteoarthritis: cross-sectional study. Biomed. Gestational age and maternal BDNF-levels remained significant factors for maternal resistin levels. Adipose Tissue Promotes an Inflammatory Response in Obesity: Role of TNF-α, IL-6, Leptin, Adiponectin, and Resistin in Insulin Resistance Adipose tissue primary function is to store excess nutrients as triacylglycerols and to release free fatty acids during fasting. In spite of its adipokine character, resistin in humans is actually produced majoritarily by immune cells, ... Only weight of the subjects was measured by Ehtesham et al and BMI was not calculated, while in the present study BMI was calculated to exclude obese individuals. J. Physiol. However, contradicting these findings, a down-regulation of resistin, expression in response to LPS in adipose tissue of FVB, mice has been identified, with no effect transcriptionally. Sood A, Shore SA. Biochimie. 1997;82(2):579–584. 25 Thus, the close relationship between higher HOMA-IR, leptin, and resistin levels and impaired renal function can be more easily observed in these patients. progression of obesity-mediated diabetes. Resistin. J. Clin. insulin resistance and risk of cardiovascular events. 20, T2DM subjects [43], such findings have been re-affirmed, by Fujinami et al. There is still a limited understanding of some of the underlying biological mechanisms of some hormones. Physiol. The precise function of adiponectin, as a therapeutic target, improving glucose metabolism by, increasing insulin sensitivity in humans, is currently of, Recent studies have highlighted the importance of, inflammation in linking obesity and the occurrence of the, metabolic syndrome, suggesting that the metabolic syn-, drome is a low-grade systemic inflammatory condition, [84].
