New discovery uncovers secret switch that could revolutionise heart attack treatment

Credit: Victo Chang Cardiac Research Institute Scientists at the Victor Chang Cardiac Research Institute in Sydney have discovered a critical new gene that it is hoped could help human hearts repair damaged heart muscle after a heart attack. Researchers have identified a genetic switch in zebrafish that turns on cells allowing them to divide and multiply after a heart attack, resulting in the complete regeneration and healing of damaged heart muscle in these fish. It s already known that zebrafish can heal their own hearts, but how they performed this incredible feat remained unknown, until now. In research recently published in the prestigious journal,

Funnel-web spider venom may one day help save the lives of heart transplant patients

Funnel-web spider venom may one day help save the lives of heart transplant patients Posted TueTuesday 9 updated WedWednesday 10 The funnel-web is Australia s most venomous spider. ( Share Print text only Cancel Striding along a sandy track, a group of scientists is doing something kids are warned not to do: looking for funnel-web spiders. Leading the pack, known as the bugs-and-drugs squad , is biochemist Glenn King from the University of Queensland, who has built a career unpicking the chemical composition of Australia s venomous creatures. He and his team have come to K gari the place you may know as Fraser Island looking for a special kind of treasure in funnel-web venom: a miracle molecule.

Heart attack research breakthrough

Premium Content   How you are treated for coronary heart disease may be dictated by your gender after a groundbreaking study identified the key genes that contribute to heart attack are different in men and women. The international study, in collaboration with Australia s The Victor Chang Cardiac Research Institute, compared hundreds of male and female patients with coronary heart disease - the leading cause of heart attack. The Institute s Executive Director, Professor Jason Kovacic, said the breakthrough pinpointed major molecular and genetic differences between men and women at high risk of having a heart attack. In the walls of the blood vessels going to the heart, at the cellular level there are fundamental differences between men and women, Prof Kovacic said.
