Drug protects mice from heart failure

"A drug seems to protect mice from heart failure even when enormous pressure is placed on their hearts. If the results can be replicated in humans, it could help millions of people avoid some of the long-term consequences of a heart attack. The new drug targets a micro RNA - a molecule that inhibits the expression of a network of genes. Researchers recently discovered that a micro RNA called miR-208 is implicated in heart failure and that mice engineered to lack the gene for miR-208 are protected against heart failure" - New Scientist
