Gfi1 regulates survival and lineage commitment of hematopoietic precursors and prevents myeloproliferative diseases

(Submitter supplied) Hematopoietic stem cells (HSCs) and lymphoid-primed multi-potential progenitors (LMPPs) are able to initiate both lymphoid and myeloid differentiation. We show here that the transcriptional repressor Gfi1 (growth factor independence 1) implements a specific gene expression program in HSCs and LMPPs that is critical for their survival and lymphoid differentiation potential. We present evidence that Gfi1 is required to maintain expression of genes involved in lymphoid development such as Flt-3, IL7R, Ebf1, Rag1, CCR9 and Notch1 and controls myeloid lineage commitment by regulating expression of genes such as Hoxa9 or M-CSFR. more...

Growth factor independence 1 knockout effect on LSK hematopoietic stem bone marrow cells

Analysis of Lin-Sca1+ckit+Flt3- (LSKFlt3-) hematopoietic stem cells (HSC) depleted of growth factor independence 1 (Gfi1). Transcriptional repressor Gfi1 restricts HSC proliferation and is essential to self-renewal. Results provide insight into molecular mechanisms underlying Gfi1 effects in HSCs.
