Fetuin-A, a circulating glycoprotein synthesized in the liver, is involved in insulin resistance and type 2 diabetes. However, regulation of fetuin-A synthesis has remained obscure. We previously reported that pioglitazone treatment significantly reduced serum fetuin-A levels in patients with type 2 diabetes. To clarify whether pioglitazone can directory inhibit hepatic fetuin-A synthesis, we i...

▼ In recent years, the number of patients with type 2 diabetes mellitus caused by insulin resistance has continued to increase in Japan. Insulin resistance is considered to be closely related to the risk of cardiovascular diseases and atherosclerotic diseases, represented by arteriosclerosis obliterans (ASO). Therefore, improvement of insulin resistance is one of the important strategies in the...

The rising incidence of obesity and insulin resistance to epidemic proportions has closely paralleled the surge in the prevalence of diabetes and outpaced therapeutic advances in diabetes prevention and treatment. Current evidence points to obesity induced oxidative stress and chronic inflammation as the common denominators in the evolution of insulin resistance and diabetes. Of all the hypogly...

Short title: Marková et al., Pioglitazone and muscle nPKC Summary It has been suggested that thiazolidinediones (TZDs) ameliorate insulin resistance in muscle tissue by suppressing muscle lipid storage and the activity of novel protein kinase C (nPKC) isoforms. To test this hypothesis, we analyzed long-term metabolic effects of pioglitazone and the activation of nPKC-and- isoforms in an anim...

Obesity and elevated cytokine secretion result in a chronic inflammatory state and may cause the insulin resistance observed in type 2 diabetes. Recent studies suggest a key role for endoplasmic reticulum stress in hepatocytes and adipocytes from obese mice, resulting in reduced insulin sensitivity. To address the hypothesis that thiazolidinediones, which improve peripheral insulin sensitivity,...

Pioglitazone is one of thiazolidinedione derivatives, which stimulates nuclear peroxisome proliferator-activated receptor gamma and improves glucose and lipid metabolism and insulin sensitivity. A recent systematic review and meta-analysis showed that pioglitazone therapy was associated with a lower risk of major adverse cardiovascular events in patients with pre-diabetes and diabetes. Further,...

The relationship between inflammation and insulin resistance is complex and not fully understood. Patients with rheumatoid arthritis are at increased risk of mortality from cardiovascular disease, which is known to be associated with insulin resistance. In the previous issue of Arthritis Research & Therapy, Ormseth and colleagues report the results of an 8-week trial of pioglitazone, an agent c...

Syndrome of extreme insulin resistance (SEIR) is a rare spectrum disorder with a primary defect in insulin receptor signalling, noted primarily in children, and is often difficult to diagnose due to the clinical heterogeneity.SEIR was diagnosed in an adolescent girl with facial dysmorphism,exuberant scalp and body hair, severe acanthosis, lipoatrophy, dental abnormalities, and short stature (Ra...

AIM to compare the effectiveness of metformin and pioglitazone in ameliorating insulin resistance and cardiovascular risk factors in women with polycystic ovary syndrome (PCOS). METHODS this study was a randomized clinical trial to compare treatment with metformin and pioglitozone. Fifty two women with PCOS aged 20-45 years were randomly allocated to one of the two treatment groups. All patie...

Insulin resistance, which precedes type 2 diabetes mellitus (T2DM), is a widespread pathology associated with the metabolic syndrome, myocardial ischemia, and hypertension. Finding an adequate treatment for this pathology is an important goal in medicine. The purpose of the present research was to investigate the effect of an extract from Aloe vera gel containing a high concentration of polyphe...
