Long non-coding RNA molecules necessary to regulate differentiation of embryonic stem cells into cardiac cells
When the human genome was sequenced, biologists were surprised to find that very little of the genome—less than 3 percent—corresponds to protein-coding genes. What, they wondered, was all the rest of ...

Enzyme CaM kinase II relaxes muscle cells: Researchers find overactive enzyme in failing hearts
A certain enzyme, the CaM kinase II, keeps the cardiac muscle flexible. By transferring phosphate groups to the giant protein titin, it relaxes the muscle cells. This is reported by researchers led by Prof. ...
