St. Jude scientists have found a protein that governs how neurons develop. This protein is called Siah2.

The study reveals how brain cells mature and form a functioning network. This study also identifies a path to treat medulloblastoma. That cancer is the most common malignant brain tumor in children.

“Medulloblastoma arises from abnormal growth of immature neurons in the brain,” said David Solecki, PhD, of Developmental Neurobiology. “A subtype of the cancer, SHH-medulloblastoma, has abnormally high activity of Siah2. In mice, inhibiting Siah2 restored normal neuronal development.”

Other scientists are developing drugs to inhibit Siah.

Nature Communications published a report on this work. 


St. Jude Children's Research Hospital

St. Jude Children's Research Hospital is leading the way the world understands, treats and cures childhood cancer and other life-threatening diseases. It is the only National Cancer Institute-designated Comprehensive Cancer Center devoted solely to children. Treatments developed at St. Jude have helped push the overall childhood cancer survival rate from 20% to 80% since the hospital opened more than 50 years ago. St. Jude freely shares the breakthroughs it makes, and every child saved at St. Jude means doctors and scientists worldwide can use that knowledge to save thousands more children. Families never receive a bill from St. Jude for treatment, travel, housing and food — because all a family should worry about is helping their child live.
