Phosphoinositide (PI) 3-kinase is involved in insulin-mediated effects on glucose uptake, lipid deposition, and adiponectin secretion from adipocytes. Genetic disruption of the p85alpha regulatory subunit of PI 3-kinase increases insulin sensitivity, whereas elevated p85alpha levels are associated with insulin resistance through PI 3-kinase-dependent and -independent mechanisms. Adipose tissue ...

BACKGROUND Chronic metabolic overload results in lipid accumulation and subsequent inflammation in white adipose tissue (WAT), often accompanied by non-alcoholic fatty liver disease (NAFLD). In response to metabolic overload, the expression of genes involved in lipid metabolism and inflammatory processes is adapted. However, it still remains unknown how these adaptations in gene expression in e...

Cold exposure imposes a metabolic challenge to mammals that is met by a coordinated response in different tissues to prevent hypothermia. This study reports a transcriptomic analysis in brown adipose tissue (BAT), white adipose (WAT) and liver of mice in response to 24 h cold exposure at 8°C. Expression of 1895 genes were significantly (P<0.05) up- or down-regulated more than two fold by cold e...

The use of dicamba and 2,4-D products on herbicide-tolerant crops has resulted in numerous cases off-target movement injury to sensitive plants, including tomato ( Solanum lycopersicon L.). Two greenhouse studies were conducted determine whether ‘Big Beef’ (‘BB’) or ‘Florida 91’ (‘FL’) plants pretreated with an antitranspirant, Moisture-Loc (ML) at 100 mL·L −1 , TransFilm (TF) 50 g·L Wilt-Pruf ...

Numerous medicinal plants and their derivatives have been reported to prevent obesity and related diseases. Although Syzygium aromaticum has traditionally been used as an anodyne, carminative and anthelmintic in Asian countries, its potential in the prevention and treatment of obesity has not yet been explored. Therefore, the present study investigated the anti-obesity effect of S. aromaticum e...

BACKGROUND Adipose afferent reflex (AAR) is a sympatho-excitatory reflex induced by chemical stimulation of white adipose tissue (WAT). Ionotropic glutamate receptors including NMDA receptors (NMDAR) and non-NMDA receptors (non-NMDAR) in paraventricular nucleus (PVN) mediate the AAR. Enhanced AAR contributes to sympathetic activation and hypertension in obesity rats. This study was designed to ...

Conjugated linoleic acid (CLA) isomers have been reported to reduce body weight and beneficially affect glucose metabolism in animals, but the results are inconsistent and seem to depend on animal model and type of CLA isomer. In the present study, feeding male Zucker fa/fa rats diets supplemented with 1% trans-10, cis-12-CLA for 10 d reduced the liver TAG content without improving the overall ...

BACKGROUND The aim of the present study was to test the hypotheses that 1) a single exercise bout increases UCP1 mRNA in both inguinal (i)WAT and epididymal (e)WAT, 2) UCP1 expression and responsiveness to exercise are different in iWAT and eWAT, 3) PGC-1α determines the basal levels of UCP1 and PRDM16 in WAT and 4) exercise and exercise training regulate UCP1 and PRDM16 expression in WAT in a ...

As white adipose tissue (WAT) expands under obesogenic conditions, local WAT hypoxia may contribute to the chronic low-grade inflammation observed in obesity. Aerobic exercise training is beneficial in treating WAT inflammation after obesity is established, but it remains unknown whether exercise training, while on a concomitant high-fat (HF) diet, influences WAT inflammation during the develop...

There are two distinct types of adipose tissue which have different functions within the body, white (WAT) and brown (BAT). Browning of WAT occurs with increases in the WAT sympathetic nervous system (SNS) drive. In this regard we previously reported that melatonin (MEL) stimulation of MEL receptor 1A (MEL1a) within the SNS outflow to the WAT might be implicated in a naturally-occurring reversa...
