Researchers identify genetic machinery responsible for synthesizing thiostrepton

Researchers at the Georgia Institute of Technology have identified the genetic machinery responsible for synthesizing thiostrepton, a powerful antibiotic produced by certain bacteria.

Discovery of gene that plays key role in process of converting dietary carbohydrates to fat

In a new study, they disabled this gene in mice, which consequently had lower levels of body fat than their normal counterparts, despite being fed the equivalent of an 'all-you-can-eat' pasta buffet.

The obesity paradox

It's called the obesity paradox. Although obese people are more apt to suffer from inflammatory diseases, such as diabetes, heart disease, and stroke, they are also more likely to survive a major attack caused by one of those conditions.

Why do teeth form in a single row?

A system of opposing genetic forces determines why mammals develop a single row of teeth, while sharks sport several, according to a study published in the journal Science.

New understanding of blinding degenerative eye conditions

Though based on mouse studies, the research bolsters the idea that humans suffering from these and other eye conditions may be able to help preserve function by adding antioxidants to their diet, and explains why this would work.

New research may lead to new pharmacologic approaches to treating obesity

Scientists at the University of North Carolina at Chapel Hill School of Medicine have discovered a gene that when mutated causes obesity by dampening the body's ability to burn energy while leaving appetite unaffected.

Topical treatment wipes out herpes with RNAi

Whether condoms or abstinence, most efforts to prevent sexually transmitted diseases have a common logic: keep the pathogen out of your body altogether.

Novel treatment option for obesity

A new study in the January 7th issue of Cell Metabolism , a Cell Press publication, helps to explain why obese people and animals fail to respond to leptin, a hormone produced by fat that signals the brain to stop eating.

Apolipoprotein D protects against Alzheimer's

Do Carmo and her collaborators have successfully demonstrated the protective and reparative role of apolipoprotein D, or ApoD, in neurodegenerative diseases. Their discovery suggests interesting avenues for preventing and slowing the progression of this type of illness.

Brain deletion of FK506-binding protein enhances repetitive behaviors in mice

A new study reveals a link between dysregulation of a common signaling pathway and repetitive behaviors similar to those associated with multiple neurological and neurodegenerative disorders including, autism spectrum disorders, obsessive compulsive disorder, schizophrenia, and Huntington's disease.

New evidence shows that the heart beats to its own drummer

They've uncovered some of the molecular circuitry within the cardiovascular system itself that controls the daily rise and fall of blood pressure and heart rate. The findings might also explain why commonly used diabetes drugs come with cardiovascular benefits, according to the researchers.

Fruit flies provide new insights into a brain-damaging disease mucolipidosis type IV

Johns Hopkins researchers have used fruit flies to gain new insights into a brain-damaging disorder afflicting children.

Discovery of novel approach to suppress prostate cancer progression

Researchers at the University of Southern California (USC) have found that inactivating a specific biomarker for aggressive prostate cancer blocks the development of prostate cancer in animal models.

Scientists discover new compounds to target muscular dystrophy

Using a drug-discovery technique in which molecules compete against each other for access to the target - the strand of toxic RNA that causes the most common form of muscular dystrophy in adults - a team at the University of Rochester Medical Center has identified several compounds that, in the laboratory, block the unwanted coupling of two molecules that is at the root of the disease.

Biologists identify genes that prevent changes in physical traits due to environmental changes

New York University biologists have identified genes that prevent physical traits from being affected by environmental changes.

Persistent bacterial infection exploits killing machinery of immune cells

A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them. This discovery may lead to new treatments and vaccines for tuberculosis (TB) and certain other chronic bacterial and parasitic infections.

Genetically modified tomatoes rich in anthocyanins

Researchers from the John Innes Centre in Norwich, Great Britain, in collaboration with other European centres participating to the FLORA project, have obtained genetically modified tomatoes rich in anthocyanins, a category of antioxidants belonging to the class of flavonoids. These tomatoes, added to the diet of cancer-prone mice, showed a significant protective effect by extending the mice lifespan. The research has been published in the 26 October issue of Nature Biotechnology.

A new role for a critical DNA repair molecule in the immune system

The human immune system is a brilliantly adaptable weapon against foreign invaders. But it all depends on the work of specialized cells called lymphocytes that have made a risky evolutionary gambit to mutate their own DNA.

Ginkgo biloba may prevent brain cell damage after a stroke

Working with genetically engineered mice, researchers at Johns Hopkins have shown that daily doses of a standardized extract from the leaves of the ginkgo tree can prevent or reduce brain damage after an induced stroke.
