PGE2 alters chromatin through H2A.Zvariant enhancer nucleosome modification to promote hematopoietic stem cell fate (Mnase-Seq)

Project description:Hematopoietic stem and progenitor cells (HSPCs) need require tight transcriptional regulation. In-depth knowledge on how epigenetic mechanisms regulate chromatin landscape in order to control gene expression, particularly in response to external stimuli, will be key to understand the pathogenesis of hematologic disorders and improve blood stem cell-based therapies. Prostaglandin E2 (PGE2) and its metabolically resistant analog 16,16-dimethyl-PGE2 (dmPGE2) were previously identified as a potent external stimulus to enhance HSPC engraftment. PGE2 has been evaluated in various clinical trials to improve engraftment of stem cells. To understand the mechanism of gene expression changes, Wwe identified that dmPGE2 mediates chromatin flexibility at HSPC-specific enhancers through histone-variant H2A.Z acetylation to promote master transcription factor (TF) binding and reinforce expression of genes involved in stem cell fate and engraftment.
