The breakdown of barriers in old cells may hold clues to aging process
Like guards controlling access to a gated community, nuclear pore complexes are communication channels that regulate the passage of proteins and RNA to and from a cell's nucleus. Recent studies by researchers ...

Researchers construct a device that mimics one of nature's key transport machines
(PhysOrg.com) -- To help protect its genes, a cell is highly selective about what it allows to move in and out of its nucleus. Yet that choosiness is regulated by just a thin barrier, perforated with tiny ...

Structural study backs new model for the nuclear pore complex
(PhysOrg.com) -- In higher organisms, the genetic material is confined and protected in the cell nucleus. In order for a healthy cell to function, the DNA must send manufacturing orders through the double ...
