Protein ‘Jailbreak’ Helps Cancer Cells Live

Researchers at Brown University and Hasbro Children’s Hospital have traced the molecular interactions that allow the protein survivin to escape the nucleus of a breast cancer cell and prolong the cell’s life. The study may help in the development of better therapies and prognostics.

PROVIDENCE, R.I. [Brown University] — If the fight against breast cancer were a criminal investigation, then the proteins survivin, HDAC6, CBP, and CRM1 would be among the shadier figures. In that vein, a study to be published in the March 30 Journal of Biological Chemistry is the police report that reveals a key moment for keeping cancer cells alive: survivin’s jailbreak from the nucleus, aided and abetted by the other proteins. The research highlights that a protein’s location in a cell affects its impact on disease, and offers clear new leads for the investigation. (more…)
