Scientists at Bristol University have found evidence for a new protein in the heart that could one day aid development of new drugs to regulate the heart.
The ability of the heart to function as a pump that drives blood around the body depends on the electrical behaviour of muscle cells from various regions of the heart. Different cardiac regions have distinct electrical events, specialised for their particular roles in the heart.
While studying the electrical activity of heart muscle cells, doctors Jules Hancox and Yin Hua Zhang from Bristol University’’s School of Medical Sciences found that insulin activates a distinct electrical signal in cellular proteins called ’’ion channels’’. This particular electrical signal was found to be different from those of known ion channels in the heart and led them to conclude that it was likely to be from a new heart ion channel.
