Thiazolidinediones are ligands for peroxisome proliferator-activated receptor (PPAR)-gamma, widely used as insulin sensitizer in type 2 diabetic patients and implicated in apoptosis, cell proliferation, and cell cycle regulation. Here, the effect of thiazolidinediones on G1-phase cell cycle arrest, the hallmark in diabetic nephropathy, was investigated. Eight-week-old male Otsuka Long-Evans Tok...

BACKGROUND Diabetes is an important global disease, associated with significant morbidity and an increased risk of death due to chronic end-organ complications. The thiazolidinediones, used mainly as third-line agents in type 2 diabetes mellitus (T2DM), have been associated with some safety concerns, such as an increased risk of bladder cancer, an increased risk of bone fracture and heterogeneo...

BACKGROUND The frequency of gastrointestinal ulcerations is higher in cirrhotic patients than in the normal population. It has been shown that pioglitazone exhibits gastroprotective actions. This study was designed to investigate the effect of pioglitazone, on the gastric mucosal lesions in cirrhotic rats. METHODS Different groups of bile duct-ligated and sham animals received solvent, or 5, ...

Pioglitazone is widely used for the treatment of diabetic patients with insulin resistance. The mechanism of pioglitazone to improve insulin sensitivity is not fully understood. Recent studies have shown that the induction of suppressor of cytokine signaling 3 (SOCS3) is related to the development of insulin resistance. Here, we examined whether the insulin-sensitizing effect of pioglitazone af...

AIMS We assessed the long-term glycaemic effects and the safety profile of triple therapy with the addition of pioglitazone vs. placebo in patients with Type 2 diabetes treated with combined metformin-sulphonylurea therapy in the PROspective pioglitAzone Clinical Trial In macroVascular Events (PROactive). METHODS In a post-hoc analysis, we identified patients treated with metformin plus sulph...

BACKGROUND AND OBJECTIVES Pioglitazone has been known for its anti-atherogenic effects. We compared the effects of pioglitazone in reducing atherosclerosis progression and neointima volume in type 2 diabetic patients. SUBJECTS AND METHODS This was a prospective, randomized single-blinded, 8-month follow-up study. Patients with significant coronary artery stenosis were randomly assigned to eit...

Pioglitazone is a thiazolidinedione derivative used for the treatment of type 2 diabetes. The drug's poor aqueous solubility and slow dissolution rate are the main causes of its limited therapeutic action in some cases. The aim of the present study is to formulate a more soluble product of pioglitazone at physiological pH. The potential interaction of pioglitazone with cyclodextrins and water-s...

BACKGROUND Peroxisome proliferator-activated receptor-gamma plays an important role in regulating inflammation. Although cardiac transplantation is an established therapy for patients with end-stage heart disease, allograft rejection is a major concern for long-term survival. We investigated the role of pioglitazone in acute and chronic rejection in a murine cardiac transplantation model. MET...

BACKGROUND AND PURPOSE Diabetes is an important risk factor for stroke. We conducted analyses in patients who had entered the PROspective pioglitAzone Clinical Trial In macroVascular Events (PROactive) with a history of stroke or without stroke. METHODS The prospective, double-blind PROactive (mean duration, 34.5 months) randomized 5238 patients with type 2 diabetes and a history of macrovasc...

Pioglitazone is a member of peroxisome proliferator-activated receptor gamma (PPARγ) agonists, particularly used in management of type II diabetes. However it also has effects in some dermatological disorders. The current study was designed to investigate the effects of oral administration of pioglitazone and the association of nitric oxide, in serotonin-induced scratching in mice. In order to ...
