Molecular alteration may be cause -- not consequence -- of heart failure

 E-Mail Clinicians and scientists have long observed that cells in overstressed hearts have high levels of the simple sugar O-GlcNAc modifying thousands of proteins within cells. Now, researchers at Johns Hopkins Medicine have found evidence in mouse experiments that these excess sugars could well be a cause, not merely a consequence or marker of heart failure. Their research found that elevated levels of O-GlcNAc made mice more prone to heart failure, but lowering levels of O-GlcNAc restored the animals risk of death and heart function to normal.
