Breast Cancers And Leukemias Slowed By A Single Therapy

Targeting a single protein can help fight both breast cancers and leukemias, according to two reports published online in the Journal of Experimental Medicine. The single protein is HSP90, which acts as a chaperone to protect other proteins in the cell. A team led by Ute Moll at the University of Göttingen in Germany found that blocking HSP90 activity rendered normally protected proteins vulnerable to attack and destruction. One of these proteins - called migration inhibitory factor - drives the growth of breast tumors...
