Longer-lived rodents have lower levels of thyroid hormone
The thyroid may play an important role in longevity, with longer-lived rodents showing significantly lower levels of a thyroid hormone that speeds metabolism, a new study has found. view more (2006-10-10)
Study shows marine omega-3 fatty acids have positive effect on muscle mass
A research team led by Carole Thivierge, from Université Laval's Institute of Nutraceutics and Functional Foods, shows that omega-3 fatty acids from fish oil have a positive effect on the metabolism of muscle proteins. view more (2007-05-10)
How protein-rich diets curb hunger
Researchers have uncovered new evidence to explain the observation that diets rich in protein stunt the appetite, according to a report in the November Cell Metabolism. view more (2005-11-09)
Not all fat created equal
It has long been known that type 2 diabetes is linked to obesity, particularly fat inside the belly. Now, researchers at the Joslin Diabetes Center have found that fat from other areas of the body can actually reduce insulin resistance and improve insulin sensitivity. view more (2008-05-07)
New therapeutic options for diabetes-related tissue injury
Diabetes mellitus is a metabolic disorder characterized by altered glucose tolerance and impaired lipid and carbohydrate metabolism, and is associated with a number of complications directly resulting from hyperglycemiainduced inflammation. view more (2008-07-07)
A new genetic model for obesity?
A gene involved in fat (lipid) metabolism, and consequently relevant for studies in obesity and diabetes, has been described in Drosophila melanogaster (fruit fly) by a team of researchers in the September issue of Mechanisms of Development. Luis Teixeira and Nathalie F. Vanzo from the European Molecular Biology Laboratory in Heidelberg, Germany,... view more... (2003-09-25)
UT-Houston's Northrup and Colleagues Uncover Genetic Link to Spina Bifida
Researchers at The University of Texas Medical School at Houston have discovered an association between genes regulating glucose metabolism and spina bifida. The decade-long study looked at more than 1,500 DNA samples from parents and their children with that birth defect. view more (2007-12-19)
microRNA-mediated metabolism
In the February 15th issue of G&D, Drs. Aurelio Teleman and Stephen Cohen (EMBL) assign one of the first biological functions to an animal microRNA: the microRNA miR-278 regulates energy homeostasis in Drosophila. view more (2006-02-15)
Researchers engineer metabolic pathway in mice to prevent diet-induced obesity
In recent years, obesity has taken on epidemic proportions in developed nations, contributing significantly to major medical problems, early death and rising health care costs. view more (2009-06-03)
Another reason to avoid high-fat diet -- it can disrupt our biological clock
Indulgence in a high-fat diet can not only lead to overweight because of excessive calorie intake, but also can affect the balance of circadian rhythms - everyone's 24-hour biological clock, Hebrew University of Jerusalem researchers have shown. view more (2008-12-29)
Drugs targeted at muscle cells can be of use in the treatment of diabetes patients with insulin resistance
Type 2 diabetes is a clinical disease characterised by disruption to the metabolism of glucose and lipids as well as to the production of and physiological reactions to insulin. These disruptions are partly due to a reduced absorption of glucose in the cells that form the body's fat and muscle tissue. Now scientists at Karolinska Institutet have... view more... (2005-04-18)
A link between mitochondria and tumor formation in stem cells
Researchers report on a previously unknown relationship between stem cell potency and the metabolic rate of their mitochondria -a cell's energy makers. Stem cells with more active mitochondria also have a greater capacity to differentiate and are more likely to form tumors. view more (2008-10-13)
Clock molecule's sensitivity to lithium sheds light on bipolar disorder
Researchers at the University of Pennsylvania School of Medicine discovered that a key receptor protein is a critical component of the internal molecular clock in mammals. What's more, this molecule -called Rev-erb- is sensitive to lithium and may help shed light on circadian rhythm disorders, including bipolar disorder. view more (2006-02-17)
ESC Congress 2004: Glucose Abnormalities in patients with Myocardial Infarction
This trial reveals important new information on the relation between reduced ability to handle glucose (sugar) and acute heart attacks. view more (2004-08-31)
Exercise could be the heart's fountain of youth
Absence may make the heart grow fonder, but endurance exercise seems to make it younger. According to a study conducted at Washington University School of Medicine in St. Louis, older people who did endurance exercise training for about a year ended up with metabolically much younger hearts. view more (2008-07-24)
From the Glass to the Brain in Six Minutes
Just one drink can quickly go to your head. Researchers in Heidelberg tested this well-known adage. view more (2009-06-16)
Plants grow bigger and more vigorously through changes in their internal clocks
Hybrid plants, like corn, grow bigger and better than their parents because many of their genes for photosynthesis and starch metabolism are more active during the day, report researchers from The University of Texas at Austin in a new study published in the journal Nature. view more (2008-11-24)
Brain system serves as 'remote control' for fat metabolism
A system in the brain already known to regulate food intake also serves as a direct "remote control" for the way fat is stored and metabolized in the body, say University of Cincinnati (UC) researchers. view more (2007-09-21)
Cholesterol metabolism links early- and late-onset Alzheimer's disease
Although the causes of Alzheimer's disease are not completely understood, amyloid-beta (A-beta) is widely considered a likely culprit - the "sticky" protein clumps into plaques thought to harm brain cells. view more (2007-10-05)
'Pachinko chances' - New theory suggests that human metabolism works like a pachinko pinball machine and may explain adverse effects of drugs
Scientists from Imperial College London and AstraZeneca have advanced a new theory that animal and human metabolisms often work like a Japanese Pachinko type pinball machine. The researchers used the new science of metabonomics to look at global human metabolism, and how it might interact with certain drugs, the environment and the gut... view more... (2003-07-31)
