Study uncovers genetic elements that drive regeneration

If you trace our evolutionary tree way back to its roots—long before the shedding of gills or the development of opposable thumbs—you will likely find a common ancestor with the amazing ability to regenerate lost body ...

Grb2 protein holds powerful molecular signaling pathway in check

Once considered merely a passive link between proteins that matter, Grb2 - pronounced "grab2" - actually lives up to its nickname with its controlling grip on an important cell signaling pathway, scientists at The University ...

New clues to human deafness found in mice

Providing clues to deafness, researchers at Washington University School of Medicine in St. Louis have identified a gene that is required for proper development of the mouse inner ear.

Small proteins in the heart play big role

A heartbeat is a carefully coordinated series of electrical signals led by sodium ion channels, which tell the heart when to contract and to relax. Any disruption to these signals may lead to cardiac diseases such as an irregular ...

How fish brain cells react to Alzheimer's disease

Zebrafish, in contrast to humans, have outstanding regenerative capacities: If brain cells are lost due to illness or injury, they will easily regrow from so-called progenitor cells. With sophisticated methods, researchers ...
