SIRT1 Activation Disrupts Maintenance of Myelodysplastic Syndrome Stem and Progenitor Cells by Restoring TET2 Function [hMeDIP-Seq]
Improved understanding of mechanisms regulating myelodysplastic syndrome (MDS) hematopoietic stem/progenitor cell (HSPC) growth and self-renewal is critical for developing MDS therapy. We revealed a novel regulatory axis that SIRT1-deficiency induced TET2 hyperacetylation promotes MDS HSPC functions, and provide an approach to target MDS HSPCs by activating SIRT1 deacetylase. Overall design: 5-hydroxymethylcytosine (5hmC) modified DNA fragments from SIRT1 overexpressed or MOCK MDS-L cells were immunoprecipited by anti-5hmC antibody for Next-Generation Sequencing
