Abstract.Resistin is a newly discovered adipocyte hormone. It is related to resistin-like molecules α, β and γ in structure and function. Resistin is produced by white and brown adipose tissues but has also has been identified in several other tissues, including the hypothalamus, pituitary and adrenal glands, pancreas, gastrointestinal tract, myocytes, spleen, white blood cells and plasma. The tissue level of resistin is decreased by insulin, cytokines such as tumour necrosis factor… 

Resistin regulates pituitary somatotrope cell function through the activation of multiple signaling pathways.

It is found that the stimulatory action of resistin occurs through a Gs protein-dependent mechanism and that the adenylate cyclase/cAMP/protein kinase A pathway, the phosphatidylinositol 3-kinase/Akt pathway, protein kinase C, and extracellular Ca(2+) channels are essential players in mediating the effects of resistsin on somatotropes.

Adiponectin and resistin: potential metabolic signals affecting hypothalamo-pituitary gonadal axis in females and males of different species.

The objective of this review was to summarise the latest findings and particularly the species and gender differences of adiponectin and resistin on female and male reproduction known to date, based on the hypothalamo-pituitary-gonadal axis.

Adipocytokines: The pied pipers

The adipose tissue secretes several bioactive mediators that influence inflammation, insulin resistance, diabetes, atherosclerosis and several other pathologic states besides the regulation of body weight, and their role in therapy has a lot in store.

Role of Resistin in Inflammation, Obesity and Type2 Diabetes mellitus

This review will place available data on resistin in the context of the current knowledge of the pathogenesis of obesity)mediated diabetes.

Resistin, an adipocytokine, offers protection against acute myocardial infarction.

Genetic and environmental determinants of circulating resistin level in a community-based sample.

The observations indicate that resistin is strongly influenced by genetic factors, and the high heritability estimates for resistin concentrations clearly suggest the continuing need for further molecular genetic investigations.

Myocardial Insulin Resistance: An Overview of Its Causes, Effects, and Potential Therapy

This review will identify and highlight some of the proposed causes of insulin resistance with particular reference to the role of dyslipidaemia, inflammation and the rennin-angiotensin system in the aetiology of this condition.



Cell type-specific expression and coregulation of murine resistin and resistin-like molecule-α in adipose tissue

It is demonstrated that the expression of resistin and RELM α are similarly regulated in adipose tissue despite the fact that RELMα is exclusively expressed in the stromal vascular fraction of adipose tissues and not in adipocytes.

Humoral regulation of resistin expression in 3T3-L1 and mouse adipose cells.

It is found that resistin expression in 3T3-L1 adipocytes was significantly upregulated by high glucose concentrations and was suppressed by insulin, suggesting that these factors affect insulin sensitivity and fat tissue mass in part by altering the expression and eventual secretion of resistin from adipose cells.

Tumor Necrosis Factor α Is a Negative Regulator of Resistin Gene Expression and Secretion in 3T3-L1 Adipocytes

It is suggested that TNFα is a pivotal negative regulator of resistin gene expression, which may have important implications for the pathogenesis of insulin resistance and its link to obesity.

Endothelin-1 inhibits resistin secretion in 3T3-L1 adipocytes.

Resistin is expressed in pancreatic islets.

Resistin and obesity-associated insulin resistance

Regulation of resistin by gonadal, thyroid hormone, and nutritional status.

The observations indicate that resistin is influenced by gender, gonadal status, thyroid hormones, pregnancy, and pregnancy, which suggests that resistsin could explain the decreased insulin sensitivity during puberty and could be the link between sex steroids and insulin sensitivity.
