okadaic acid/비만증

The effect of okadaic acid, an inhibitor of protein phosphatases-1 and -2A, was studied on glucose transport and metabolism in soleus muscles isolated from lean and insulin-resistant obese mice. In muscles from lean mice, the uptake of 2-deoxyglucose, an index of glucose transport and

A high-glucose diet (HGD) is associated with the development of metabolic diseases that decrease life expectancy, including obesity and type-2 diabetes (T2D); however, the mechanism through which a HGD does so is still unclear. Autophagy, an evolutionarily conserved mechanism, has been shown to

Obesity increases the risk of developing several cancers including oesophageal adenocarcinoma (OAC). Obesity is characterised by hyperleptinaemia and hypoadiponectinaemia: we have hypothesised that these hormonal factors may contribute to the progression of OAC. We have examined the effects of

It is known that protein phosphatase 2A (PP2A) expression is increased in high-fat diet (HFD)-induced obese mice, but the role of PP2A in adipogenesis as well as obesity remains to be addressed. In this study, the role of PP2A in adipogenesis was explored. Preadipocytes were treated with okadaic

Tumor necrosis factor-alpha (TNF-alpha) is a proposed mediator of insulin resistance in obese/diabetic animals through its effects on tyrosine phosphorylation of the insulin receptor and its substrate, insulin receptor substrate-1. In this study, the acute effects of TNF-alpha on the

Leptin, the 16 kDa protein product of the ob gene, is secreted by adipocytes. The long form leptin receptor (ObRb) is expressed at high levels in the hypothalamus, and regulates appetite and energy expenditure. The fact that serum concentration of leptin is correlated with body mass index (BMI)

Guggulsterone, derived from Commiphora mukul and used to treat obesity, diabetes, hyperlipidemia, atherosclerosis, and osteoarthritis, has been recently shown to antagonize the farnesoid X receptor and decrease the expression of bile acid-activated genes. Because activation of NF-kappaB has been

Natural products with distinct biological activities are very promising molecular probes to dissect the novel pathways of biology. FR177391, a product of bacteria, was obtained as a natural compound possessing anti-hyperlipidemic effects. FR177391 enhances differentiation of mouse 3T3-L1 fibroblasts

Homeodomain interacting protein kinase-2 (HIPK2) is an evolutionary conserved kinase that modulates several key molecular pathways to restrain tumor growth and induce p53-depending apoptotic cell-death in response to anticancer therapies. HIPK2 silencing in cancer cells leads to chemoresistance and

Tumor necrosis factor-alpha (TNF) has been suggested to be the mediator of insulin resistance in infection, tumor cachexia, and obesity. We have previously shown that TNF diminishes insulin-induced tyrosine phosphorylation of insulin receptor substrate 1 (IRS-1). The current work examines potential
