Metabolic switch required for cellular adaptation to hypoxia

Two new studies in the March Cell Metabolism reveal a survival mechanism by which cells adapt to oxygen starvation by ratcheting down their demand.

Scientists design a fluorescent sensor capable of measuring intracellular acidity

The colouring agents traditionally used to stain organic tissues are no longer sufficient to meet today’s needs. The study of cell metabolism can only advance with better tools than those currently available.

Hedgehog protein plays a role in regulating fat and bone

A protein that guides the early development of creatures as diverse as fruit flies and humans also plays a role in regulating fat and bone formation in adult organisms, researchers at UT Southwestern Medical Center have discovered.

Brain plays a major role in the ability of insulin therapy to lower blood sugar in animals with diabetes

"Our findings suggest that, in individuals with diabetes, the ability of insulin to lower blood sugar involves the brain," said senior author of the study, Michael Schwartz of the University of Washington at Seattle. "This effect is not trivial; the brain makes a substantial contribution to insulin response."

Liver plays crucial role in iron metabolism

A new study in the December Cell Metabolism reveals an unexpected connection between a tumor suppressor gene in the liver and the normally careful control over the amount of iron absorbed from the diet.

Bright light therapy may aid patients with depressive and bipolar disorders

A report in the November Cell Metabolism reveals powerful effects of light on the adrenal glands, a finding that might explain the broad benefits of bright light therapy for a variety of conditions, including sleep and depressive disorders, according to researchers.

Molecular origins of diabetes

An unexpected twist to a discovery reported just two months ago may significantly improve our understanding about the molecular origins of diabetes.

How protein-enriched meals decrease hunger and reduce eating

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.

New hormone discovery has implications for liver diseases

Researchers at UT Southwestern Medical Center have discovered that the small intestine communicates with the liver to control the production of bile acids - a finding that has great medical implications in treating people at risk for certain types of liver disease.

Obesity associated with a threefold increase in SCD1 expression in obese muscle

The gene encoding an enzyme that hinders muscle from burning fat manufactures three times more enzyme in the muscle of obese people than lean people, researchers from Duke University Medical Center and Louisiana State University have found. This causes the obese muscle tissue to both store more fat and burn less fat, the researchers said.

Sleletal muscle findings highlight the importance of exercise in obese people

The findings suggest that muscle bears a metabolic memory of obesity, which may help to explain why sustained weight loss can be difficult despite cutting calories, according to the researchers. Exercise might more successfully override the aberrant metabolic program in muscle, they suggest, thereby improving the long-term prognosis of those prone to obesity.

Newly discovered hormone plays an important role in the digestion of fat, cholesterol, and fat-soluble vitamins

A newly discovered hormone plays an important role in the digestion of fat, cholesterol, and fat-soluble vitamins, such as vitamins A, E, and D, according to a new study in the October 2005 issue of Cell Metabolism.

Study reveals critical molecular events in the origin of fat cells

A new study reveals critical molecular events in the origin of fat cells. The findings are central to understanding chronic diseases, such as obesity and diabetes, as fat cells produce hormones critical for metabolic control, the researchers said.

Low-dose aspirin might prevent the cardiovascular damage known to arise from use of the painkiller rofecoxib (Vioxx)

Their findings that a chemical imbalance might underlie such damage could also lead to the development of anti-inflammatory drugs without the adverse side effects, the researchers said.

Increasing sugar processing in the liver may lead to future treatments for diabetes, obesity

Researchers at the University of Minnesota have shown that increasing the concentration of a key regulator involved in glucose metabolism can improve the way the liver produces and disposes of the sugar glucose, the primary fuel of the body. Finding ways to increase that concentration could provide a treatment for diabetes and obesity.

SH2-B enhances brain's leptin sensitivity - may lead to clues for treatment of obesity and diabetes

What do laboratory mice at the University of Michigan Medical School have in common with millions of overweight Americans? Like many of us, these mice just can't stop eating.

Protein Sirt1 points to new therapies for type 2 diabetes

Opening the possibility of new therapies for type 2 diabetes, researchers at Washington University School of Medicine in St. Louis have found that a protein called Sirt1 enhances the secretion of insulin in mice and allows them to better control blood glucose levels. Their study appears in the August 17 issue of Cell Metabolism.
