We discover and evaluate novel biomarkers and therapeutic targets that can rapidly improve the lives of patients with bladder and prostate cancer. To do this, we integrate information from massive genomic databases, our own experimental studies, and carefully curated human biospecimens. The result is a powerful approach that uses every available type of analysis. The laboratory has ongoing projects refining the use of a variety of biomarkers to guide clinical management.

Our experimental work has identified genes such as SOX9, Nestin, and members of the Notch signaling pathway, which pattern urogenital organs in the embryo and remodel tissues after injury. We have found that these same signals are also reactivated in cancers, helping them form, grow and spread. Within urogenital cancers, some cells are particularly prolific, serving as so called “cancer stem cells.” We identified basal cells in bladder cancers and showed that they function as cancer stem cells with unique functions in tumour-stroma interactions. Ongoing projects in the laboratory examine these interactions and their potential changes through different stages of bladder cancer progression.
