Nutrition and heredity are genetically linked
A challenging goal in biology is to understand how the principal cellular functions are integrated so that cells achieve viability and optimal fitness under a wide range of nutritional conditions.   view more (2007-05-17)

Human reproductive rates follow biological scaling rules
In nations with high per capita energy consumption, women have fewer children. This phenomenon is an unexpected consequence of the biological scaling relationship between metabolism and reproductive rate: larger species of mammals have higher metabolism but lower birth rates. In the April 2003... view more (2003-04-08)

Could mice hold the secret to longer life?
Scientists from the University of Aberdeen, the Aberdeen-based Rowett Research Institute and the Medical Research Council (MRC) in Cambridge have made a major breakthrough in understanding how metabolism affects lifespan. In a seven-year study of mice they found that those with the highest... view more (2004-05-28)

Diets high in choline may increase risk for colorectal polyps
Contrary to expectations, diets high in the nutrient choline were associated with an increased risk of some colorectal polyps, which can-but do not always-lead to colorectal cancer.   view more (2007-08-08)

Scientists a step closer to producing fuel from bacteria
Scientists at the University of Sheffield have shown how bacteria could be used as a future fuel. The research, published in the journal Bioinformatics, could have significant implications for the environment and the way we produce sustainable fuels in the future.   view more (2008-08-07)

Abnormal glucose metabolism may contribute to chronic nerve disorder
Abnormal glucose metabolism, which occurs when the body has difficulty processing sugar (glucose) into energy, is twice as common among patients with chronic nerve dysfunction of unknown cause than among the general population and may be a risk factor for the condition.   view more (2006-06-13)

Estrogen curbs appetite in same way as the hormone leptin
Estrogen regulates the brain's energy metabolism in the same way as the hormone leptin, leading the way to a viable approach to tackling obesity in people resistant to leptin.   view more (2007-01-04)

Cocaine's effects on brain metabolism may contribute to abuse
Many studies on cocaine addiction - and attempts to block its addictiveness - have focused on dopamine transporters, proteins that reabsorb the brain's "reward" chemical once its signal is sent.   view more (2008-02-19)

A potential sugar fix for tumors
Researchers at the Duke School of Medicine apparently have solved the riddle of why cancer cells like sugar so much, and it may be a mechanism that could lead to better cancer treatments.   view more (2008-04-16)

A maternal link to Alzheimer's disease
People who have a mother with Alzheimer's disease appear to be at higher risk for getting the disease than those individuals whose fathers are afflicted, according to a new study by NYU School of Medicine researchers.   view more (2007-11-07)

Fitting in: Newly evolved genes adopt a variety of strategies to remain in the gene pool
When Mother Nature creates an identical copy of a gene in an organism's genome, the duplicated copy is usually deleted, inactivated, or otherwise rendered nonfunctional in order to prevent genetic redundancy and to preserve biological homeostasis.   view more (2005-10-03)

Protective action of a molecule in inflammatory processes discovered
Henar Hevia Pérez, researcher in the area of Genic Therapy and Hepatology at the Applied Medicine Research Centre (CIMA)of the University of Navarra, has discovered the protective role of the methylthioadenosine (MTA) molecule in an in vivo inflammation model.   view more (2006-04-27)

Deakin University researcher unveils pregnancy mystery
Belinda Hardman completed the study for her PhD with Deakin's Centre for Cellular and Molecular Biology under the supervision of Dr Leigh Ackland.   view more (2007-03-06)

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... 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)

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... 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,... 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)
