New findings on heat shock proteins may shed light on variety of debilitating diseases
UCLA researchers, in a finding that runs counter to conventional wisdom, have discovered for the first time that a gene thought to express a protein in all cells that come under stress is instead expressed only in specific ...

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. ...
