Glucocorticoid excess promotes visceral obesity and cardiovascular disease. Similar features are found in the highly prevalent metabolic syndrome in the absence of high levels of systemic cortisol. Although elevated activity of the glucocorticoid-amplifying enzyme 11beta-hydroxysteroid dehydrogenase
Adipose tissue macrophages (ATMs) are involved in the development of insulin resistance in obesity. We have recently shown that myeloid cell-specific reduction of 3- hydroxy-3-methylglutaryl-coenzyme A reductase (Hmgcrm-/m- ), which is the rate-limiting enzyme in cholesterol
This study was designed to evaluate the hypocholesterolemic effects of masou salmon 70% ethanol extract (MSE) and to determine the molecular mechanism by which MSE exerts its effects in high-fat (HF) diet-induced obese mice. We hypothesize that the MSE may contain abundant n-3 fatty acids, so a diet
Visceral obesity is linked to insulin resistance and cardiovascular disease. A recent genetic study indicated that the gene locus for the anti-oxidant defense enzyme methionine sulphoxide reductase A (MsrA) is positively associated with the development of visceral adiposity. This work tested the
11-β-Hydroxysteroid dehydrogenase type 1 (11β-HSD1) converts cortisone to cortisol, mainly in the liver and visceral adipose tissue (VAT), and has been implicated in several metabolic disorders. The absence of systemic hypercortisolism in central obesity could be due to increased inactivation of
Serum cholesterol concentrations, lecithin-cholesterol acyltransferase (LCAT), and hepatic 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase activities of lean and obese Zucker rats were compared. The excess serum cholesterol of the female obese rat is found to be mainly free cholesterol
OBJECTIVE
In men with symptomatic benign prostatic hyperplasia 5α-reductase inhibitors are a main modality of treatment. More than 30% of men do not respond to the therapeutic effects of 5α-reductase inhibitors. We have found that a third of adult prostate samples do not express 5α-reductase type 2
Methylenetetrahydrofolate reductase (MTHFR) polymorphism may play an important role in the pathophysiology of obesity and diabetes accompanied by obesity due to its influence on plasma homocysteine levels. There are significant and sometimes very strong relationship between levels of homocysteine
BACKGROUND
Obesity is a complex disease that involves both genetic and environmental perturbations to gene networks in adipose tissue and is proposed as a trigger for metabolic sequelae.
OBJECTIVE
We hypothesized that expression of adipose tissue transcripts in gene networks for adaptive response
The goal of this study is to determine whether cardiovascular risk and the methylenetetrahydrofolate reductase 677 C->T polymorphism (MTHFR), an enzyme involved in folate metabolism and in epigenetics, are linked in morbidly obese non-diabetic adolescents. One-hundred and thirteen obese (BMI = 39.1
Inhibitors of 3-hydroxy-3-methyl glutaryl coenzyme A (HMG-CoA) reductase have been approved for treatment of hypercholesterolemia in humans. This class of therapeutic agents, in addition to lowering plasma cholesterol, reduces plasma triglyceride levels. We have investigated the mechanism of
BACKGROUND
Oxidative stress is a key factor in the development of the principal comorbidities of obesity. Methylenetetrahydrofolate reductase enzyme (MTHFR) participates in the metabolism of folate with the action of vitamins B6 and B12. The gene of MTHFR may present a single nucleotide polymorphism
We examined the effect of atorvastatin, an inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase, on the kinetics of apolipoprotein B-100 (apoB) metabolism in 25 viscerally obese men in a placebo-controlled study. Very-low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL),
Erythrocyte acid phosphatase (ACP locus 1), also known as low-molecular-weight protein tyrosine phosphatase, has previously been associated to glycemia, dyslipidemia, and obesity. In this study, ACP1 genotype and activity were tested in 318 women aged 19 to 83 (mean, 51.74 +/- 13.44) years. ACP1
Obesity is often associated with an elevated total body cholesterol synthesis. In order to evaluate the role of hepatic cholesterogenesis in this phenomenon, we assayed the rate-limiting step in cholesterol biosynthesis, 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase in the microsomal
