Post-transcriptional regulation of hematopoietic stem cell function during normal and malignant hematopoiesis

In 2016, there were approximately 22,510 Canadians living with leukemia and an estimated 2,900 Canadians died from leukemia. Acute myeloid leukemia (AML) is one of the most common types of leukemia in adults. About 30 percent of AML patients eventually relapse after treatment and suffer from very poor overall survival at this stage. It is postulated that leukemia stem cells (LSCs), a small population of leukemia cells characterized with regenerative ability, mediate resistance and relapse after therapy. My work sought to uncover the largely unknown role of the processes that control protein generation in maintaining blood stem cells and how it contributes to transformation of leukemia stem cells in cancer. This research program aims to identify new factors, which can serve as targetable molecules and pathways to specifically eliminate leukemia cells while sparing normal cells. The work will provide the scientific foundation for future developments of therapy targeting these pathways as a novel strategy in eradicating leukemia stem cells to improve outcomes in AML patients.
