Epigenetic targeting of dormant leukemic stem cells

B07

Project Summary

Leukemic Stem Cells (LSCs) reside in a long-term quiescent state, reversal of LSC quiescence drives acute myeloid leukemia (AML) relapse. We identified distinct DNA methylation changes upon healthy hematopoietic stem cells (HSCs) commitment. Our data suggest a novel role for Gprc5c as a marker of LSC dormancy. Thus, we hypothesise that dormant LSCs are epigenetically distinct and that targeting the epigenetic landscape of Gprc5c+-LSCs might delay relapse. We propose to define the epigenetic features of dormant Gprc5c+-LSCs in AML and compare them to healthy dormant HSCs. This may allow us to determine novel therapeutic avenues in AML.
