Scientists produce clearest-ever images of enzyme that plays key roles in aging, cancer.

An enzyme called telomerase plays a significant role in aging and most cancers, but until recently many aspects of the enzyme’s structure could not be clearly seen. Scientists from UCLA and UC Berkeley have produced images of telomerase in much higher resolution than ever before, giving them major new insights about the enzyme. Their findings, could ultimately lead to new directions for treating cancer and preventing premature aging. “Many details we could only guess at before, we can now see...

Delivering missing protein heals damaged hearts in animals

Researchers have discovered that a particular protein, Fstl1, plays a key role in regenerating dead heart-muscle cells. Scientists at the Stanford University School of Medicine and their colleagues have enabled damaged heart tissue in animals to regenerate by delivering a protein to it via a bioengineered collagen patch. There is currently no effective treatment to reverse the scarring in the heart after heart attacks. Heart attacks cause millions of deaths annually worldwide and are predi...
