Epigenetic effects of NFE2 and JAK2V617F mutations in MPN

B02

Project Summary

We have defined distinct classes of NFE2 mutations in patients with myeloproliferative neoplasms (MPN) and could demonstrate that elevated expression of the transcription factor NFE2 in MPN patients is regulated by epigenetic pathways. Now we will integrate changes in the transcriptome and histone modifications conferred by wt-NFE2 and the NFE2 mutations, to understand how NFE2 alters the epigenetic landscape to promote leukemic transformation. These data will allow us to discriminate between two alternative pathophysiological models of disease initiation and progression.
