Scientists kill cancer cells by 'shutting the door' to the nucleus
Scientists at Sanford Burnham Prebys Medical Discovery Institute have shown that blocking the construction of nuclear pores complexes—large channels that control the flow of materials in and out of the cell nucleus—shrank ...

Disorderly DNA helps cancer cells evade treatment
Each cell in the human body holds a full two meters of DNA. In order for that DNA to fit into the cell nucleus—a cozy space just one hundredth of a millimeter of space—it needs to be packed extremely tight.
