SIRT1 Activation Disrupts Maintenance of Myelodysplastic Syndrome Stem and Progenitor Cells by Restoring TET2 Function

An improved understanding of the mechanisms regulating myelodysplastic syndrome (MDS) hematopoietic stem/progenitor cell (HSPC) growth and self-renewal is critical for developing MDS therapy. Sun et al. report that SIRT1 deficiency-induced TET2 hyperacetylation promotes MDS HSPC function and provides an approach to target MDS HSPCs by activating SIRT1 deacetylase.
