Point mutations of the transcription factor AML1 are associated with leukemogenesis in acute myeloblastic leukemia (AML). Internal tandem duplications (ITDs) in the juxtamembrane domain and mutations in the second tyrosine kinase domain of the Fms-like tyrosine kinase 3 (FLT3) gene represent the most frequent genetic alterations in AML. However, such(More)
Alterations in the IKZF1 gene are associated with poor prognosis in pediatric B-cell acute lymphoblastic leukemia (B-ALL). We examined the relationship between IKZF1 alterations and clinical findings in 78 adult patients with B-ALL. Aberrant isoforms of IKZF1 were detected using RT-PCR. The copy numbers of IKZF1 exons and fusion genes caused by exon(More)
AML1-MTG8 generated by t(8;21) contributes to leukemic transformation, but additional events are required for full leukemogenesis. We examined whether mutations in the receptor tyrosine kinase (RTK) pathway could be the genetic events that cause acute myeloblastic leukemia (AML) harboring t(8;21). Mutations in the second tyrosine kinase domain,(More)
C/EBPalpha plays an essential role as a transcription factor in myeloid cell differentiation. Here, we describe a Japanese family in which two individuals with acute myeloid leukemia (AML) and one healthy individual had an identical 4-base pair insertion in the N-terminal region of CEBPA (350_351insCTAC), resulting in the termination at codon 107(More)
The mud shrimp, Upogebia major is a gonochoristic species with distinct sexual dimorphism; however, the male has the "ovarian part of testis" in the gonad and mature-looking eggs appear in a similar reproductive cycle to the female. Vitellogenesis of U. major was investigated focusing on the characterization of vitellogenin (Vg) gene expression and Vg(More)
Cyclin-dependent kinase inhibitor p15 is frequently inactivated by either methylation or deletion in patients with acute leukemia. To examine pathologic and clinical significance of the p15 gene inactivation, we established a quantitative assay of p15 mRNA expression in the bone marrow cells by real-time quantitative reverse transcriptase-polymerase chain(More)
