This article is available online at http://www.jlr.org The peroxisome proliferator-activated receptors (PPARs) are a family of transcription factors belonging to the nuclear receptor superfamily. The PPAR family consists of three subtypes, PPAR , PPAR , and PPAR / , all of which are regulated by fatty acids and their derivatives. The PPARs bind to peroxisome proliferator response elements (...

Methods: To evaluate the vascular role of PPAR we used a conditional null mouse model. Specific disruption of PPAR in ECs was created by crossing Tie2-Cre transgenic (T2T ) and PPAR -floxed (fl/fl) mice to generate PPAR (fl/fl)T2T (PPAR E-null) mice. Conscious 8to 12-week-old congenic PPAR (fl/fl)Cre (wild type) and PPAR E-null mice were examined for changes in systolic blood pressure (BP) and ...

Peroxisome proliferator-activated receptors (PPARs) are a group of ligand-dependent nuclear receptors responsible for gene expression regulation and function as transcriptional regulators of adipogenic differentiation and lipid metabolism. Members of PPAR family, especially PPAR gamma, are predominantly expressed in adipose tissue and have been demonstrated as important regulators of stem cell ...

Alzheimer’s disease (AD) is undoubtedly one of the serious and growing public health challenges in the world today. There is an unmet need for new and effective preventative and therapeutic treatment approaches for AD, particularly at early stages of the disease. However, the underlying mechanism against Aβ-induced electrophysiological alteration in cultured hippocampal pyramidal neurons  is st...

The mechanism(s) underlying renoprotection by peroxisome proliferator-activated receptor (PPAR)-γ agonists in diabetic and nondiabetic kidney disease are not well understood. Mitochondrial dysfunction and oxidative stress contribute to kidney disease. PPAR-γ upregulates proteins required for mitochondrial biogenesis. Our aim was to determine whether PPAR-γ has a role in protecting the kidney pr...

The role of peroxisome proliferator--activated receptor- δ (PPAR δ) gene in colon carcinogenesis remains highly controversial. Here, we established nude mice xenograft model using a human colon cancer cell line KM12C either with PPAR δ silenced or normal. The xenografts in PPAR δ-silenced group grew significantly larger and heavier with less differentiation, promoted cell proliferation, increas...

Cerebellar abnormalities in fetal alcohol spectrum disorder (FASD) have been linked to brain insulin resistance and oxidative stress. Peroxisome proliferator-activated receptor (PPAR) agonists, which have insulin sensitizer and antioxidant effects, could potentially be used to treat neurodevelopmental abnormalities in FASD. Slice cultures generated with cerebella from control or ethanol-exposed...

Therapeutic use of certain peroxisome proliferator-activated receptor (PPAR) alpha agonists (fibrates) for the treatment of dyslipidemia has infrequently been associated with the untoward side effect of myopathy. With interest in PPAR-delta as a therapeutic target, this study assessed whether a PPAR-delta agonist induced similar hepatic and skeletal muscle alterations as noted with some fibrate...
