Scientists at Cold Spring Harbor Laboratory (CSHL) have discovered a new drug target for Ewing sarcoma, a rare kind of cancer usually diagnosed in children and young adults. Their experiments show that the cells causing this cancer can essentially be reprogrammed with the flick of a genetic switch. Shutting down a single protein forces the cancer cells to take on a new identity and behave like normal connective tissue cells, a dramatic change that reins in their growth. This discovery suggests researchers may be able to stop Ewing sarcoma by developing a drug that blocks the protein known as ETV6. Ewing sarcoma causes tumors to grow in bones or the soft tissues surrounding them. Once a tumor begins to spread to other parts of the body, it can be very difficult to halt the disease’s progression. Even for patients with positive outcomes, treating Ewing sarcoma often causes toxic side effects. New treatments are badly needed, says CSHL Professor Christopher Vakoc, MD, PhD, who led the research on ETV6.
