Scientist identifies how lack of dopamine leads to symptoms of Parkinson's

A scientist at the Gladstone Institutes has identified how the lack of a brain chemical known as dopamine can rewire the interaction between two groups of brain cells and lead to symptoms of Parkinson's disease.

Daily moderate drinking may decrease atherosclerosis

For the first time, new research shows that patterns of alcohol consumption - a drink or two every night, or several cocktails on Friday and Saturday nights only - may be more important in determining alcohol's influence on heart health than the total amount consumed.

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.
