Fasting elicits a progressive increase in lipid metabolism within skeletal muscle. To determine the effects of fasting on the transcriptional regulation of genes important for metabolic control in skeletal muscle composed of different fiber types, nuclei from control and fasted (24 and 72 h) rats were subjected to nuclear run-on analysis using an RT-PCR-based technique. Fasting increased (P < 0...
Uncoupling protein 1 (UCP1) is the first UCP described. It belongs to the family of mitochondrial carrier proteins and is expressed mainly in brown adipose tissue. Recently, the family of the UCPs has rapidly been growing due to the successive cloning of UCP2, UCP3, UCP4, and UCP5, also called brain mitochondrial carrier protein 1. Phylogenetic studies suggest that UCP1/UCP2/UCP3 on one hand an...
In humans Uncoupling Proteins (UCPs) are a group of five mitochondrial inner membrane transporters with variable tissue expression, which seem to function as regulators of energy homeostasis and antioxidants. In particular, these proteins uncouple respiration from ATP production, allowing stored energy to be released as heat. Data from experimental models have previously suggested that UCPs may...
This study aimed to study the effects of acylated ghrelin on glucose and triglyceride metabolism in rat myoblasts under palmitic acid- (PA-) induced high fat conditions. Rat myoblasts were treated with 0, 10(-11), 10(-9), or 10(-7) M acylated ghrelin and 0.3 mM PA for 12 h. Triglyceride accumulation was determined by Oil-Red-O staining and the glycerol phosphate dehydrogenase-peroxidase enzymat...
The present study was designed to determine if dietary protein can alter uncoupling protein (UCP) expression in swine, as has been shown in rats, and attempt to identify the mechanism. Eight pigs (approximately 50 kg body mass) were fed an 18% crude protein (CP) diet while another eight pigs were switched to a diet containing 12% crude protein (CP) and fed these diets until 110 kg body mass. Th...
OBJECTIVE We performed an association study to identify gene polymorphisms for assessing the genetic risk of ischemic or hemorrhagic stroke. METHODS AND RESULTS The study population comprised 3151 unrelated Japanese individuals: 1141 stroke patients (636 with atherothrombotic cerebral infarction, 282 with intracerebral hemorrhage, and 223 with subarachnoid hemorrhage) and 2010 controls. The g...
The aim of this study was to investigate the effects of a post-weaning isocaloric hyper-soybean oil diet on later obesity and explore the underlying mechanisms. In the present study, newborn male Wistar rats were weaned on d 24, divided into CON (control), HC and HSO groups. CON was assigned to AIN-93G diet (a hypercarbohydrate diet, for short HC diet) during the entire experiment. HC and HSO w...
We investigated the relative importance of overeating, thermogenesis, and uncoupling protein (UCP) expression in determining the severity of obesity in male Wistar rats fed a highly palatable diet. After 2 wk of feeding, body weight did not differ significantly from controls (248 +/- 4 vs. 229 +/- 3 g; P > 0.3), but rectal temperature, brown adipose tissue (BAT) mass, UCP3 expression in gastroc...
Impaired activity of the uncoupling protein (UCP) family has been proposed to promote obesity development. The present study examined differences in UCP responses to cold exposure between leptin-resistance obese (db/db) mice and their lean (C57Ksj) littermates. Basal UCP1 and UCP3 mRNA expression in brown adipose tissue was lower in obese mice compared with lean mice, but UCP2 expression in whi...
