Researchers Discover ‘Doorways’ Into Brain Cells

Come on in, we saved a place for youBrain cell membranes have established “doorways” that accept or reject molecules trying to pass into the cell, researchers have founbd. The discovery fundamentally changes how researchers think about the behavior of neurons. It had been long believed that surface molecules such as receptors are enveloped right where they rest in the fatty membrane, to be drawn into the cell’s interior.

Researchers Elucidate Machinery of Major Anti-Cancer Drug Target

Researchers have detailed the functioning of an enzyme that is a central component of a signaling pathway important for about 30 percent of cancers. The findings about how the enzyme, called farnesyl transferase (FTase), works could help improve the FTase-inhibiting drugs that pharmaceutical companies are now testing to fight a broad spectrum of cancers.
