Isocitrate dehydrogenase 1 mutation (IDH1-R132H) was recently identified in acute myeloid leukemia with normal cytogenetics. The mutant enzyme is thought to convert α-ketoglutarate to the pathogenic 2-hydroxyglutarate (2-HG) that affects DNA methylation via inhibition of ten-eleven translocation 2. However, the role of wild-type IDH1 in normal hematopoiesis(More)
Zebrafish is a powerful model for the investigation of hematopoiesis. In order to isolate novel mutants with hematopoietic defects, large-scale mutagenesis screening of zebrafish was performed. By scoring specific hematopoietic markers, 52 mutants were identified and then classified into four types based on specific phenotypic traits. Each mutant(More)
Neutrophils are the key effectors for generating innate immunity in response to pathogenic infection and tissue injury in vertebrates. Dysregulation of neutrophil development and function is known to associate with various human disorders. Yet, the genetic network that orchestrates lineage commitment, differentiation, and maturation of neutrophils remains(More)
Neutrophils play important roles in innate immunity and are mainly dependent on various enzyme-containing granules to kill engulfed microorganisms. Zebrafish nephrosin (npsn) is specifically expressed in neutrophils; however, its function is largely unknown. Here, we generated an npsn mutant (npsnsmu5 ) via CRISPR/Cas9 to investigate the in vivo function of(More)
