The gene that repairs the heart after a heart attack

Today the journal “Science” publishes a study carried out at the Victor Chang Heart Research Institute (USA) which reveals the identification of a genetic change in zebrafish that activates cells and allows them to divide and multiply later of a heart attack. As a result of this process, complete regeneration and healing of the damaged heart muscle occurs in these fish. It is already known that the zebrafish is able to heal its own hearts, but until now it was unknown how it achieved it. In this research, the researchers focused on the Klf1 gene, which had previously only been identified in red blood cells. And for the first time they discovered that it plays a vital role in healing … See More
