A new recovery for heart attacks,,

Researchers form Australia have correlated a molecular 'switch' that helps our body's cells make up when oxygen levels fall, a finding that could provide the basis for future drugs to help in recovery from stroke and heart attack. //

A team from the University of Adelaide's Molecular Biosciences department and CSIRO Health Sciences and Nutrition report their findings in this week's issue of Science.It is known that certain genes are energized in low-oxygen conditions. These genes help increase delivery of oxygen by making more red blood cells and blood vessels. They also reduce the body's reliance on oxygen by switching to a form of energy production not dependent on oxygen, called glycolysis (which uses glycogen from the liver).

Previous research has found that a protein known as Hypoxia Inducible Factor (HIF) responds to low oxygen levels and switches on the genes. However, the nuts and bolts of how it does that have to date only been partially understood.HIF was identified as having two segments that were involved in the switching process. One segment had been found to be reliable for increasing the amount of HIF in the cell. Under normal circumstances HIF is constantly made and broken down. However researchers have found that under low-oxygen levels, HIF loses a hydroxyl (oxygen and hydrogen) group from a proline amino acid on this domain. This changes the shape of the protein and makes it less likely to be degraded.

The other domain of HIF was known to be responsible for the actual activation of genes that helped cells adapt to low oxygen, however the molecular switch for that has to date been unknown.Dr Whitelaw and colleagues found under low-oxygen levels, HIF loses a hydroxyl molecule from an asparagine amino acid on this other domain. This changes the shape of the protein and allows it to activate the genes.

"The finding has implications for treating heart diseases in which tissues are deprived of oxygen because th
