Outline of Final Research Achievements |
Chronic myelomonocytic leukemia (CMML) is a refractory and recurrent hematopoietic malignancy. We identified SLITRK4 as a causative gene of CMML by using induced pluripotent stem cells (iPSC) from CMML patient-derived leukemic cells. We disrupted SLITRK4 gene in CMML iPSC via CRISPR/Cas9 system, and the production of hematopoietic progenitor cells (HPC) from CMML-iPSC was dramatically attenuated in SLITRK4 dose-dependent manner. In addition, SLITRK4 was knocked down after hematopoietic differentiation from CMML-iPSC and Normal-iPSC, and the number of CMML-HPC-derived colonies was reduced by knockdown of SLITRK4, although Normal-HPC-derived colonies did not change. Next, we performed Gene Ontology Enrichment Analysis and found genes related to cytoskeleton and cell cortex such as SPTA1 and SPTBN1 were highly expressed in CMML-HPC compared to Normal-HPC.
