Mechanism and implications of brown adipose tissue proliferation in rats and monkeys treated with the thiazolidinedione darglitazone, a potent peroxisome proliferator-activated receptor-gamma agonist.
Thiazolidinediones represent an established class of insulin sensitizing agents for treating noninsulin-dependent diabetes mellitus. Darglitazone, a thiazolidinedione approximately 200x more potent than ciglitazone, was evaluated in preclinical safety assessment studies using rats (1, 5, and 50 mg/kg/day) and cynomolgus monkeys (50, 75, and 100 mg/kg/day). Darglitazone was a potent adipogenic a...

Objective(s): The aim of current study was to evaluate improving effects of pioglitazone as an agonist of peroxisome proliferator-activated receptor gamma (PPARγ), on brain-derived neurotrophic factor (BDNF) and cytokines as well as tissue oxidative damage criteria in the hippocampus in a rat model of lipopolysaccharide (LPS) induced memory impairment.<strong...

متن کاملThiazolidinediones inhibit the expression of beta3-adrenergic receptors at a transcriptional level.
The effect of the thiazolidinediones (TZDs) darglitazone and troglitazone on beta3-adrenergic receptor (AR) expression was studied in cultured cell lines representing several tissues. After 24 h of exposing HIB-1B brown adipocytes to 30 micromol/l darglitazone or 20 micromol/l troglitazone, beta3-AR mRNA levels were reduced by 75%. This effect was significant within 1 h of exposure to a maximal...
متن کاملAdipose Gene Expression Profiles Related to Metabolic Syndrome Using Microarray Analyses in Two Different Models
BACKGROUND Peroxisome proliferator-activated receptor-γ (PPAR-γ) agonist has a wide-ranging influence on multiple components of metabolic syndrome. The Otsuka Long-Evans Tokushima Fatty (OLETF) rat is a useful animal model of metabolic syndrome. To determine genes related to metabolic syndrome, we examined overlapping genes that are simultaneously decreased by PPAR-γ agonists and increased in O...
