Outline of Final Research Achievements

We examined the effects of JAK2 and TET2 mutations on myeloproliferative neoplasms (MPNs) development and disease progression. Recipients of JAK2V617F cells developed primary myelofibrosis-like features. The addition of TET2-loss worsened this phenotype. Double-mutant (JAK2V617F plus TET2-loss) myeloid cells were more likely to be in a proliferative state than JAK2V617F single-mutant cells. In a serial competitive transplantation assay, JAK2V617F cells resulted in decreased chimerism in the second recipients, which did not develop MPNs. In marked contrast, cooperation between JAK2V617F and TET2-loss developed and maintained MPNs in the second recipients. In-vitro sequential colony formation assays also supported the observation. We conclude that loss of TET2 has two different roles in MPNs: disease accelerator and disease initiator and sustainer in combination with JAK2V617F.
