Excerpt from the news article:

Dr. Paola Marignani is a scientist in the Faculty of Medicine at Dalhousie University and for the past several years she has dedicated her research to a specific form of breast cancer.

“Years ago we discovered that in one of the more aggressive forms of breast cancer, HER2- positive breast cancer, there was a specific type of protein that was not doing its job and this protein is called LKB1 and we were trying to understand why in HER2-positive breast cancer this protein was missing,” says Marignani.

They mimicked the cancer in mice and removed the protein. They saw the tumours grow and become metabolically active.
