Toxoplasma gondii directly affects production of dopamine in brain

A research group from the University of Leeds has shown that infection by the brain parasite Toxoplasma gondii, found in 10-20 per cent of the UK's population, directly affects the production of dopamine, a key chemical messenger in the brain.

Early diagnosis of large intestine cancer could be feasible in the long term

Itxaro Perez, a biochemist at the University of the Basque Country (UPV/EHU), has contributed in such a way that, in the long term, the early diagnosis of cancer of the large intestine could be feasible.

Scientists discover alternative mechanism for extension of telomeres

Scientists of the German Cancer Research Center have discovered an alternative mechanism for the extension of the telomere repeat sequence by DNA repair enzymes.

Cancer cells maintain rapid proliferation due to PK-M2 enzyme

Cancer cells maintain their life-style of extremely rapid growth and proliferation thanks to an enzyme called PK-M2 (pyruvate kinase M2) that alters the cells' ability to metabolize glucose - a phenomenon known as the Warburg effect.

The brain and the heart may not be so different after all

What do heart disease and dementia have in common? Perhaps more than meets the eye, according to researchers at the University of Rochester Medical Center.

Study reveals what causes lysosome to overflow in Batten disease

Waste management is a big issue anywhere, but at the cellular level it can be a matter of life and death. A Weizmann Institute study, published in the Journal of Cell Biology, has revealed what causes a molecular waste container in the cell to overflow in Batten disease, a rare but fatal neurodegenerative disorder that begins in childhood.

Pupil can constrict without any input from brain

You've seen it on television: A doctor shines a bright light into an unconscious patient's eye to check for brain death. If the pupil constricts, the brain is OK, because in mammals, the brain controls the pupil. Or does it? Now, researchers at Johns Hopkins have discovered that in most mammals, in fact in most vertebrates, the pupil can constrict without any input from the brain.

Researchers discover key enzymes that are critical for sperm function

Compared to most other cells in an organism, sperm undergo a radical transformation to become compact and mobile delivery systems for paternal DNA. Even though sperm looks and moves quite differently across species, SF State researcher Diana Chu and colleagues now say that there are at least a few key enzymes that are critical for sperm development and mobility in species as different as mice and nematode worms.

Health risk associated with harmful substances in food may be underestimated

Mice are often used to test whether substances in food are harmful to humans. This requires that mice and humans metabolise substances in the same way. Humans have certain enzymes in more parts of the body than mice. The health risk associated with harmful substances in food may therefore be underestimated.

Peroxiredoxin enzyme holds key to ageing process

By consuming fewer calories, ageing can be slowed down and the development of age-related diseases such as cancer and type 2 diabetes can be delayed. The earlier calorie intake is reduced, the greater the effect. Researchers at the University of Gothenburg have now identified one of the enzymes that hold the key to the ageing process.

Leg muscle dysfunction related to severity of symptoms in heart failure patients

Doctors should not only treat the heart muscle in chronic heart failure patients, but also their leg muscles through exercise, say researchers in a study published today in the Journal of Applied Physiology.

Infinity commences two IPI-145 Phase 1 clinical trials for hematologic malignancies

Infinity Pharmaceuticals, Inc. today announced that it has initiated two Phase 1 clinical trials of IPI-145, a potent, orally available inhibitor of phosphoinositide-3-kinase (PI3K) delta and gamma. These two enzymes are implicated in hematologic cancers as well as a broad range of inflammatory conditions, which are the areas of focus within Infinity's PI3K clinical development program.

Researchers shed light on inner workings of endocycle

An international team of researchers led by investigators in the U.S. and Germany has shed light on the inner workings of the endocycle, a common cell cycle that fuels growth in plants, animals and some human tissues and is responsible for generating up to half of the Earth's biomass.

New library for development of targeted cancer drugs

In a technical tour de force, scientists at Fox Chase Cancer Center have cataloged and cross-indexed the actions of 178 candidate drugs capable of blocking the activity of one or more of 300 enzymes, including enzymes critical for cancer and other diseases. Additionally, a free library of the results has been made available online to the research community. This unique library represents an important new tool for accelerating the development of an entire class of targeted cancer drugs.

Python heart holds surprises that could be of use in cardiology

The expanding hearts of pythons have intrigued researchers. Leslie Leinwand - a University of Colorado at Boulder molecular biologist who studies heart disease in humans called pythons’ expanding hearts “amazing biology”. “They're not swelling up. They're building (heart) muscle,” he said.
