Scientists uncover molecular passports that regulate Cell Nuclei

Jerusalem [Israel], October 23 (ANI/TPS): Israeli and US scientists have discovered how tiny gateways in human cells control what enters and leaves the cell's nucleus, solving a mystery that has puzzled researchers and could shed new light on cancer, Alzheimer's, and ALS, Hebrew University of Jerusalem announced.

An international team from Hebrew University of Jerusalem, the Quantitative Biosciences Institute (QBI) at the University of California, San Francisco, The Rockefeller University, and Albert Einstein College of Medicine found that these gateways use a flexible protein network and special molecular "passports" to move molecules quickly and accurately.

The gateways, called nuclear pore complexes (NPCs), are microscopic structures -- each about one five-hundredth the width of a hum
