Evidence suggests that visceral fat accumulation plays a central role in the development of metabolic syndrome. Excess visceral fat causes local chronic low-grade inflammation and dysregulation of adipocytokines, which contribute in the pathogenesis of the metabolic syndrome. These changes may affect the gene expression in peripheral blood cells. This study for the first time examined the assoc...

Neonatal obesity predisposes individuals to obesity throughout life. In rats, neonatal overfeeding also leads to early accelerated weight gain that persists into adulthood. The phenotype is associated with dysfunction in a number of systems including paraventricular nucleus of the hypothalamus (PVN) responses to psychological and immune stressors. However, in many cases weight gain in neonatall...

The circadian rhythm, controlled by a complex network of cellular transcription factors, orchestrates behavior and physiology in the vast majority of animals. The circadian system is comprised of a master clock located in central nervous system with 24-hour rotation and periphery clocks to ensure optimal timing of physiology in peripheral tissues. Circadian expression of peroxisome proliferator...

Globoid cell leukodystrophy (GLD; Krabbe disease), is a rare heritable metabolic disorder in humans, dogs, mutant twitcher mice, and rhesus monkeys that is caused by a deficiency in the lysosomal enzyme galactocerebrosidase (GALC). GALC deficiency results in the accumulation of psychosine, which is toxic to oligodendrocytes and Schwann cells of the central and peripheral nervous systems. Clinic...

One of the 'side effects' of our modern lifestyle is a range of metabolic diseases: the incidence of obesity, type 2 diabetes and associated cardiovascular diseases has grown to pandemic proportions. This increase, which shows no sign of reversing course, has occurred despite education and new treatment options, and is largely due to a lack of knowledge about the precise pathology and etiology ...

An intermediate in the fatty acid biosynthetic pathway, malonyl-coenzyme A (CoA), has emerged as a major regulator of energy homeostasis not only in peripheral metabolic tissues but also in regions of the central nervous system that control satiety and energy expenditure. Fluctuations in hypothalamic malonyl-CoA lead to changes in food intake and peripheral energy expenditure in a manner consis...

The circadian system is primarily entrained by the ambient light environment and is fundamentally linked to metabolism. Mounting evidence suggests a causal relationship among aberrant light exposure, shift work, and metabolic disease. Previous research has demonstrated deleterious metabolic phenotypes elicited by chronic (>4 weeks) exposure to dim light at night (DLAN) (∼ 5 lux). However, the m...

metabolic syndrome is a chronic low-grade inflammation condition which is associated with central obesity, dyslipidemia, insulin resistance and hypertension. inflammation in metabolic syndrome is not only associated with elevated serum inflammatory markers, such as c-reactive protein (crp), but also, is associated with low-grade inflammation in adipose tissue and releasing of adipokines. higher...

In most species--from cyanobacteria to humans--genetically encoded circadian clocks have evolved to adapt behavioral and physiological processes to environmental changes brought about by the Earth's rotation. Clock disruption, e. g. by shift work, can lead to circadian misalignment, promoting the development of metabolic, immune and cognitive dysfunction. In mammals, a central circadian pacemak...

With a steadily increasing prevalence, insulin resistance (IR) is a major public health issue. This syndrome is defined as a set of metabolic dysfunctions associated with, or contributing to, a range of serious health problems. These disorders include type 2 diabetes, metabolic syndrome, obesity, and non-alcoholic steatohepatitis (NASH). According to the literature in the field, several cell ty...
