How proteins cluster to ensure a regular heartbeatUniversity of Cambridge | Dr Antony Jackson
On the surface of each heart muscle cell are tiny pores, or ion channels. These open and close to let sodium, calcium and potassium ions flow in and out of the cells, and generate the electrical signal that causes the heart to contract and ...

Is zinc important in ensuring the normal heartbeat?University of St Andrews | Dr Samantha Pitt
In healthy people, calcium is released from large stores in heart cells through specialised ‘gates’ called ryanodine receptors. The release of calcium into the cell causes the heart to beat strongly. But in patients with heart failure, calc...

Bolstering the heart’s defences against chemotherapy and diabetesUniversity of Leeds | Professor Derek S Steele
In the cells of our body, day-to-day processes cause the creation of ‘reactive oxygen species’ (ROS) – toxic molecules that can cause damage to our cells. In the heart, excessive ROS production can cause dangerous irregular heart rhythms. ...
