<p>Feb. 19, 2008 (PhysOrg.com)- A longstanding puzzle in neurodevelopment may have yielded up a key secret. A team led by scientists at Weill Cornell Medical College says they have determined how events at the very tips of the developing neuron’s long, skinny axon affect gene transcription back in the cell’s distant nucleus.</p> <p>The study also revealed the first-ever evidence of a transcription factor — proteins that influence gene activity — working outside the cell’s nucleus…</p> <p>&nbsp;</p>
