Oncolytics Biotech Inc. Collaborators Present Head and Neck Cancer Biomarker Preclinical Research at UK Oncolytic Virus Conference

CALGARY, April 14, 2014 /PRNewswire/ - Oncolytics Biotech Inc. ("Oncolytics") (TSX:ONC) (NASDAQ: ONCY) today announced that a poster authored by Bolton, et al was presented at the 8th Annual International Conference on Oncolytic Virus Therapeutics held in Oxford, UK. The poster, titled "Resistance to oncolytic reovirus is associated with high expression of Yes-Associated Protein (YAP-1) in head and neck cancer," covered preclinical research focused on identifying biomarkers predictive of sensitivity/resistance to reovirus in head and neck cancer cell lines.

Researchers examined reovirus in panels of head and neck cancer cell lines to determine their sensitivity to reovirus-induced oncolysis. The study results showed that high YAP-1 protein expression correlated with reovirus resistance, whereas low YAP-1 expression correlated with sensitivity to reovirus infection. They also indicated that knocking the YAP-1 gene down resulted in certain cells becoming significantly more sensitive to reovirus infection. The researchers concluded that YAP-1 is a possible biomarker for sensitivity/resistance to reovirus infection in head and neck cancer and that further investigation into the crosstalk between chemical signaling pathways upstream and downstream of YAP-1 and its cellular localization, is important in understanding how it may be impeding reovirus oncolysis.

"Identifying biomarkers that could be predictive of patient outcomes has played an increasingly greater role across both our preclinical and clinical programs," said Dr. Brad Thompson, President and CEO of Oncolytics. "We have focused on integrating biomarker analysis into many of our studies with the goal of identifying patients that stand to benefit from specific treatment regimens."

The poster will be available on the Oncolytics website at http://www.oncolyticsbiotech.com/for-investors/presentations.
