Loss of Dnmt3a impairs hematopoietic homeostasis and myeloid cell skewing via the PI3Kinase pathway II. Loss of Dnmt3a impairs hematopoietic homeostasis and myeloid cell skewing via the PI3Kinase pathway II

Inhibition of PI3K rescues Dnmt3a loss driven leukemia. The signaling pathways by which DNMT3A mutations contribute to myeloid transformation are poorly understood. We investigated that loss of Dnmt3a in HSC/Ps results in myeloproliferation, which is associated with hyperactivation of the PI3Kinase pathway. Overall design: Comparative gene expression profiling analysis of RNA-seq data for vehicle and PI3Kab-inhibitor treated WBM transplants of Dnmt3a knocokout cells.
