Study Discovers 'Hero' Protein That Helps Repair DNA and Prevent Cancer...

• Good News Network

DNA replication and repair happens thousands of times a day in the human body and most of the time, people don't notice when things go wrong thanks to the work of Replication protein A (RPA), the 'guardian of the genome.'

Scientists previously believed this protein 'hero' responsible for repairing damaged DNA in human cells worked alone, but a new study by Penn State College of Medicine researchers showed that RPA works with an ally called the WAS protein (WASp) to 'save the day' and prevent potential cancers from developing.

The researchers uncovered these findings after observing patients with Wiskott-Aldrich syndrome (WAS), which not only suppresses immune system function but, in some cases, causes cancer.  They realized that this genetic disorder is caused by a deficiency of WASp.
