Research Summary

Research in the Logue Lab focuses on cell stress responses. These pro-survival pathways are essential for the maintenance of cell health but when dysregulated can contribute to the progression of diseases including multiple forms of cancer. In our lab we focus on one stress response called the Unfolded Protein Response or UPR. We study the signaling pathways that control the UPR and ask how these pathways help promote cancer progression. One cancer we focus on is a form of breast cancer called Triple Negative Breast Cancer (TNBC). Unlike healthy cells, in TNBC cells the UPR is permanently switched on. Our research asks how sustained UPR activation supports TNBC progression and responsiveness to commonly used therapies such as chemotherapy. Answering these questions will (1) increase our basic understanding of TNBC and the pathways which support its progression and (2) help us answer if switching off the UPR would be a good therapeutic approach for the treatment of TNBC.


The Logue Lab research program focuses on cell stress responses and in particular one stress response called the Unfolded Protein Response (UPR). Our goals are to (1) understand the cellular signaling pathways that support the UPR and (2) investigate how inappropriate activation of the UPR promotes cancer progression.

Research Biography

Dr. Logue completed her undergraduate BSc (Hons) in Biochemistry followed by a Masters in Medical Science at the Queen’s University of Belfast, Northern Ireland. She then moved to the National University of Ireland, Galway to complete her PhD focused on endoplasmic reticulum stress induced cell death. Following her PhD, Dr. Logue completed postdoctoral training in the area of cell stress, cell death and inflammation. Dr. Logue's work has helped increase our fundamental understanding of the cell signaling pathways underpinning these essential cellular responses. In 2019, Dr. Logue joined the University of Manitoba, where her research program focuses on understanding the role of the Unfolded Protein Response in health and disease.
