Viral protein identified as one of the main drivers of virus-induced stomach cancers

Some common pathogens, like the Epstein-Barr virus (EBV), can turn healthy cells into cancer cells, but it is not well understood how they do so. Better understanding how such pathogens work allows researchers to find new ways to target the pathogen’s disease-causing mechanisms and ultimately find new treatments for certain virus-induced cancers.

Dr. Ivan Borozan, from Dr. Vincent Ferretti’s Lab at OICR, and Prof. Lori Frappier at the University of Toronto are working together to better understand EBV and how it triggers the transformation of normal cells to cancerous cells, also known as oncogenesis. Together, they have identified that a key protein expressed by EBV, BKRF4, is one of the likely drivers behind EBV-induced stomach cancers.

Scientists create method to sensitize triple-negative breast cancer to common immunotherapy

Drs. Marie-Claude Bourgeois-Daigneault and John Bell

Immunotherapy, which boosts the body’s immune system to kill cancer cells, has shown remarkable promise in treating many types of cancer. Now researchers have found a way to use immunotherapy against triple-negative breast cancer (TNBC), one of the most lethal forms of breast cancer. Previously, TNBC was resistant to immune checkpoint inhibitors, a common class of immunotherapies. Using a new strategy, the scientists achieved a cure rate of up to 90 per cent in mouse models.

Finding new ways to prevent virus-induced stomach cancers

The link between some viruses and cancer has long been established. Now, researchers like OICR’s Dr. Ivan Borozan are using genomic sequencing to analyze common viruses like Epstein-Barr (also called human herpes virus 4). This knowledge could ultimately be used to develop new therapeutic vaccines to keep these viruses from taking hold in the body and prevent associated cancers from ever developing in the first place.
