520 ▼a PRDM16 is a transcriptional co-regulator that is highly expressed in HSCs and required for their maintenance. It is also involved in translocations in acute myeloid leukemia (AML), myelodysplastic syndromes (MDS) and T-cell acute lymphoblastic l
520 ▼a The aim of this thesis was to more clearly elucidate the role of each Prdm16 isoform in normal and malignant hematopoiesis. We first showed that Prdm16 is essential for adult HSC maintenance using a conditional deletion mouse model specific for
520 ▼a We used a mouse model of human MLL-AF9 leukemia and found that leukemia derived from Prdm16-deficient HSCs had extended latency, although expression of Prdm16 decreases during MLL-AF9 transformation and is undetectable in ex vivo leukemic cells.
520 ▼a Finally, we performed an analysis of PRDM16 in human AML from the publically-available Cancer Genome Atlas dataset, containing clinical and gene expression data for 179 cases of AML. PRDM16 expression negatively correlated with overall survival,
520 ▼a Our findings demonstrate distinct roles for Prdm16 isoforms in both normal hematopoiesis and AML, and identify s-Prdm16 as one of the drivers of prognostically-adverse inflammatory gene expression in leukemia.
