There is substantial evidence that the decreased risk of lung cancer with high intake of vegetables and fruits is linked to folate as a specific nutrient. Functional polymorphisms in genes encoding one-carbon metabolism enzymes, methylenetetrahydrofolate reductase (MTHFR C677T and A1,298C), methionine synthase (MTR A2,756G), methionine synthase reductase(More)
Internal tandem duplication of the FLT3 gene and point mutations of the N-RAS gene are the most frequent somatic mutations causing aberrant signal-transduction in acute myeloid leukemia (AML). However, their prognostic importance is unclear. In this study, their prognostic significance was analyzed in 201 newly diagnosed patients with de novo AML except(More)
Despite the identification of numerous key players of the cell death machinery, little is known about their physiological role. Using RNA interference (RNAi) in vivo, we have studied the requirement of all Drosophila caspases and caspase-adaptors in different paradigms of apoptosis. Of the seven caspases, Dronc, drICE, Strica and Decay are rate limiting for(More)
PURPOSE Adult T-cell leukemia-lymphoma (ATL) is usually resistant to conventional chemotherapies, and there are few other treatment options. Because CC chemokine receptor 4 (CCR4) is expressed on tumor cells from most patients with ATL, KW-0761, a humanized anti-CCR4 monoclonal antibody, which markedly enhances antibody-dependent cellular cytotoxicity, was(More)
De novo CD5+ diffuse large B-cell lymphoma (CD5+ DLBCL) is known to have phenotypically and genotypically different characteristics than CD5- DLBCL and mantle cell lymphoma (MCL). To further characterize CD5+ DLBCL, 109 patients with CD5+ DLBCL were reviewed, and the results were compared with those of 384 CD5- DLBCL and 128 cyclin D1+ MCL patients.(More)
The entire nucleotide sequences of 70 hepatitis B virus (HBV) isolates of genotype B (HBV/B), including 38 newly determined and 32 retrieved from the international DNA database (DDBJ/EMBL/GenBank), were compared phylogenetically. Two subgroups of HBV/B were identified based on sequence divergence in the precore region plus the core gene, one with the(More)
The canoemisty1 (cnomis1) mutation was isolated by virtue of its severe rough eye phenotype from approximately 500 fly lines, each harboring a single autosomal insertion of a P element (Bm delta w). Excision of the P element generated a lethal, null allele, cnomis10, together with many revertants with normal eye morphology. Ommatidia homozygous for(More)
Bortezomib is an effective agent for treating multiple myeloma (MM). To investigate the underlying mechanisms associated with acquired resistance to this agent, we established two bortezomib-resistant MM cell lines, KMS-11/BTZ and OPM-2/BTZ, the 50% inhibitory concentration values of which were respectively 24.7- and 16.6-fold higher than their parental(More)
Adult T-cell leukemia/lymphoma (ATLL) is a distinct clinical entity among mature T-cell neoplasms, and its causative agent has been confirmed to be long-term infection by human T-lymphotropic virus type 1. A recent study demonstrated frequent expression of a chemokine receptor, CC chemokine receptor (CCR)4, which is known as a Th2 marker but not CXC(More)
Mutations in the spin gene are characterized by an extraordinarily strong rejection behavior of female flies in response to male courtship. They are also accompanied by decreases in the viability, adult life span, and oviposition rate of the flies. In spin mutants, some oocytes and adult neural cells undergo degeneration, which is preceded by reductions in(More)
