Biochemists reveal interaction between tumor suppressor protein and chaperone

Every cell has thousands of proteins whose activity and lifetime must be regulated to control the cellular life cycle from cell division to cell death. The heat shock protein Hsp90 plays a key role in this process. It is a so-called chaperone, a quality controller, as it were. It monitors and controls the quality and activity of many important signal proteins and helps them take on the right form. When the cell is exposed to high stress levels from heat or a lack of oxygen, Hsp90 is produced in larger quantities to shield its partner proteins from damage.

New surprising discovery on division of mitochondria within cells

A surprising new discovery by the University of Colorado Boulder and the University of California, Davis regarding the division of tiny "power plants" within cells known as mitochondria has implications for better understanding a wide variety of human diseases and conditions due to mitochondrial defects.

Developing technologies to improve treatment of craniosynostosis in babies

Engineers and surgeons are working together to improve the treatment of babies born with craniosynostosis, a condition that causes the bone plates in the skull to fuse too soon. Treating this condition typically requires surgery after birth to remove portions of the fused skull bones, and in some cases the bones grow together again too quickly -- requiring additional surgeries.

Study: Protein's structural arrangement can change its signaling function

In a joint study, scientists from the California and Florida campuses of The Scripps Research Institute have shown that changes in a protein's structure can change its signaling function and they have pinpointed the precise regions where those changes take place.

Researchers identify new genetic cause of inherited Parkinson's disease

A large team of international researchers have identified a new genetic cause of inherited Parkinson's disease that they say may be related to the inability of brain cells to handle biological stress.

Loss of estrogen receptor alpha protein may lead to metabolic syndrome

UCLA researchers demonstrated that loss of a key protein that regulates estrogen and immune activity in the body could lead to aspects of metabolic syndrome, a combination of conditions that can cause Type 2 diabetes, atherosclerosis and cancer. Called estrogen receptor alpha, this protein is critical in regulating immune system activity such as helping cells suppress inflammation and gobble-up debris.

Biomaterials may heal chronic diabetic wounds

Biomaterials may prove key to healing chronic wounds in Diabetic patients, delegates will hear today at the 24th European Conference on Biomaterials. Over 950 delegates are at the event in Dublin, which is jointly hosted by NUI Galway's Network of Excellence for Functional Biomaterials and the University of Ulster, Jordanstown.

Researchers discover new genetic defect that can lead to Leigh syndrome

In Leigh syndrome, infants are born apparently healthy only to develop movement and breathing disorders that worsen over time, often leading to death by the age of 3. The problem is that the mitochondria responsible for powering their cells can't keep up with the demand for energy in their developing brains.

Pancreatic mesenchyme plays central role in the formation of mature beta cells

A somewhat mysterious soft tissue found in the fetus during early development in the womb plays a pivotal role in the formation of mature beta cells the sole source of the body's insulin. This discovery, made by scientists at University of California, San Francisco (UCSF) and Texas A&M University, may lead to new ways of addressing Type 1 and Type 2 diabetes.

Scientists uncover new ways to stimulate pancreatic beta cell growth

One of the holy grails in diabetes research is to discover molecules that stimulate beta cell growth and to find drugs that target these molecules. Now, JDRF-funded researchers in collaboration with the pharmaceutical company Hoffmann-La Roche, have done both, discovering not only a protein that regulates beta cell growth, but also a chemical compound that stimulates it.

Researchers investigate special diets that could help youngsters keep the weight off

A shocking 17 per cent of boys and 15 per cent of girls aged two to 15 years are obese in the UK, putting them at risk of serious, long-term health problems. Now a team of Aberdeen researchers are investigating special diets which could help youngsters keep the weight off, thanks to a grant from children's charity Action Medical Research.

Discovery of a key protein’s role in cell clearance could impact future treatments of autoimmune diseases, obesity and atherosclerosis

The healthy human body is extremely efficient at cleaning house. Every day, we purge 100 to 200 billion dead or dying cells – a process called cell clearance, which is fundamental in our ability to maintain a healthy physiological balance and prevent a number of chronic diseases. Professional cleaning cells, called phagocytes, are responsible for ridding the body of dead, or ‘apoptotic,’ cells.

Researchers discover novel way to increase amounts of antibiotics

A novel way of increasing the amounts of antibiotics produced by bacteria has been discovered that could markedly improve the yields of these important compounds in commercial production. It could also be valuable in helping to discover new compounds. With the ever-growing threat from antibiotic resistance, these tools will be very useful in ensuring that we have enough of these useful compounds in the future.
