Mitochondrial transcription factor A (TFAM), a member of the high mobility group proteins, is essential for maintenance of mitochondrial DNA (mtDNA). Most TFAM and mtDNA (both of which are normally soluble) was recovered from the particulate fraction of human placental mitochondria when extracted with the non-ionic detergent Nonidet P-40. mtDNA and TFAM(More)
Mogamulizumab (MOG), a humanized anti-CC chemokine receptor 4 (CCR4) monoclonal antibody, has recently played an important role in the treatment of adult T cell leukemia/lymphoma (ATLL). Because CCR4 is expressed on normal regulatory T cells as well as on ATLL cells, MOG may accelerate graft-versus-host disease (GVHD) by eradicating regulatory T cells in(More)
Mammalian mitochondria contain strong nuclease activity. Endonuclease G (endoG), which predominantly resides in mitochondria, accounts for a large part of this nuclease activity. It has been proposed to act as an RNase H-like nuclease on RNA.DNA hybrids (R-loops) in the D-loop region where the origins of mitochondrial replication are mapped, providing RNA(More)
Bortezomib and melphalan have synergistic effects against multiple myeloma (MM) cells. We conducted a pilot study on the combination of bortezomib and high-dose melphalan (Bor-HDM) as a conditioning regimen followed by autologous stem cell transplant (ASCT) in 17 Japanese patients with newly diagnosed MM, in comparison with a historical control of patients(More)
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) from an HLA-matched related donor has been suggested to improve the poor prognosis of adult T-cell leukemia/lymphoma (ATLL). However, the infusion of HTLV-I-infected cells from HTLV-I-positive related donors could lead to the development of donor-derived ATLL under immunosuppressive conditions.(More)
OBJECTIVE The feasibility and efficacy of high-dose melphalan (HD-MEL) followed by autologous hematopoietic stem cell transplantation (auto-SCT) in elderly patients with multiple myeloma (MM) are discussed. METHODS We retrospectively analyzed and compared the results of 25 elderly patients (aged 65-76 years, elderly group) and 63 control patients (aged(More)
A 76-year-old man suffered from swelling stoma for several weeks. A biopsy sample revealed the diffuse infiltration of large lymphoid cells which were positive for CD20, bcl-6, and MUM1. The patient was diagnosed with diffuse large B-cell lymphoma, with a non-germinal center B-cell pattern. A whole-body PET-CT scan revealed that the lymphoma was restricted(More)
Hepatitis-associated aplastic anemia (HAA) has been reported to show a successful outcome following immunosuppressive treatment. On the other hand, the long-term prognosis of HAA has not been sufficiently clarified. Herein we report a patient with HAA who had been treated with cyclosporine for one year, and maintained complete remission without treatment.(More)
We previously conducted a phase 1 study of bortezomib, doxorubicin and intermediate-dose dexamethasone (iPAD) therapy and determined the optimal dose of bortezomib to be 1.0 mg/m(2). We then conducted a multicenter phase 2 study in patients with relapsed or refractory myeloma. Bortezomib 1.0 mg/m(2) was administered intravenously on days 1, 4, 8 and 11, in(More)
We present the case of a 62-year-old Japanese woman with relapsed adult T-cell leukemia/lymphoma (ATLL) who was treated with humanized anti-CCR4 monoclonal antibody (KW-0761). Although this antibody was highly effective against refractory ATLL, 6 months after the final KW-0761 infusion, the patient complained of hypoxia due to diffuse panbronchiolitis.(More)
