Kristin Hope is a Senior Scientist at the Princess Margaret Cancer Centre, University Health Network, and Associate Professor in the Dept. of Medical Biophysics at the University of Toronto. Dr. Hope earned a Ph.D. Degree in Molecular Genetics from the University of Toronto. She then went on to a postdoctoral fellowship in Montreal, in the laboratory of Dr. Guy Sauvageau. Dr. Hope started her own laboratory at McMaster University in 2010 and she and her team moved to the University of Toronto in 2020.

Our research sets out to identify novel stem cell regulators that could inform the design of enhanced hematopoietic stem cell-based regenerative therapies one on hand and cancer stem cell-targeted anti-leukemic therapies on the other. In particular we are exploring the premise that RNA binding protein-driven post-transcriptional control is a critical mode by which stemness and transformation are regulated in hematopoiesis. We interrogate this unique paradigm through three major research themes:

Identifying mediators of hematopoietic stem cell self-renewal. Blood stem cell transplants can be a curative cancer treatment however in many cases are limited by donor samples having too few stem cells. Our research uses functional genetics approaches coupled with in vivo pre-clinical stem cell read-outs in xenotransplantation assays to identify post-transcriptional mediators of hematopoietic stem cell expansion.

Defining the RNA binding protein effectors of leukemic stem cell function in myeloid leukemia. Using genetic strategies and loss and gain of function approaches we capitalize on a combination of mouse and primary human leukemia patient sample model systems to identify RNA binding proteins whose dysregulation underlies leukemogenesis and leukemic stem cell-driven relapse.

Dissecting the integrated role of RNA binding proteins in stemness from a systems perspective. RNA binding proteins synchronously regulate the fates of functionally similar RNAs, in what have been termed “RNA regulons”. We use a variety of unbiased genome and proteome scale approaches to define the rules that govern this regulation and determine key downstream circuitries of stem cell regulating RNA binding proteins whose targeting could provide the basis for novel regenerative and/or anti-leukemic treatments.
