Peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS) with genomic aberrations has been shown to resemble lymphoma-type adult T-cell leukemia/lymphoma (ATLL) in terms of its genomic aberration patterns, histopathology, and prognosis. We have shown recently that a majority of patients with acute-type ATLL have multiple subclones that were likely(More)
Constitutive nuclear factor-kappa B (NF-κB) activation has been reported in ocular adnexal lymphoma (OAL). TNFAIP3/A20 is a "global" inhibitor of NF-κB pathway. We have shown that OAL has preferential loss of the 6q23.3 region where TNFAIP3/A20 exist, which is suggested to involve in lymphomagenesis of OAL. The mechanisms causing NF-κB activity in OAL(More)
OBJECTIVE To investigate the effects of diabetes on orthodontic tooth movement and orthodontically induced root resorption in rats. SETTING AND SAMPLE POPULATION Twenty-three 10-week-old male Sprague-Dawley rats divided into control (n = 7), diabetes (n = 9), and diabetes + insulin (n = 7) groups. MATERIALS AND METHODS Diabetes was induced by(More)
In the present study, we investigated subpopulations of natural killer (NK) cells and the expression of stimulatory and inhibitory NK receptors after adult blood and bone marrow transplantation (BBMT) and cord blood transplantation (CBT). There were significant increases in CD16(+)CD56(dim) cell proportion and in absolute number in peripheral blood(More)
The prognosis of patients receiving allogeneic hematopoietic stem cell transplantation (HSCT) for refractory acute lymphoblastic leukemia (ALL) is very poor. To improve survival rates, we attempted to intensify the conditioning regimen with daunorubicin, vincristine, prednisolone, medium-dose etoposide, cyclophosphamide, and total body irradiation(More)
OBJECTIVE To investigate differences in the amount of tooth movement and root resorption that occurred after tipping and bodily movement of the maxillary first molar in rats. MATERIALS AND METHODS Ten-week-old female Wistar rats were divided into two groups according to type of tooth movement and subdivided into four subgroups according to the magnitude(More)
Adult T-cell leukemia/lymphoma (ATL) is a human T-cell leukemia virus type-1-induced neoplasm with four clinical subtypes: acute, lymphoma, chronic, and smoldering. Although the chronic type is regarded as indolent ATL, about half of the cases progress to acute-type ATL. The molecular pathogenesis of acute transformation in chronic-type ATL is only(More)
Mantle cell lymphoma (MCL) is an aggressive B-cell non-Hodgkin lymphoma (NHL) characterized by the translocation t(11;14)(q13;q32). This lymphoma exhibits a poor prognosis and remains incurable with standard chemotherapy approaches. Recently, we have shown that a majority of patients with acute-type adult T-cell leukemia/lymphoma (ATLL) have multiple(More)
NK cell neoplasms are lymphoid malignancies with an aggressive clinical course. In the present study, we analyzed gene expression profiling of NK cell neoplasms and attempted to identify important molecular pathways and new effective drugs. Pathway analysis of gene expression profiles suggested the important roles of the JAK-STAT pathway, NF-κB pathway or(More)
Evidence is accumulating that hematologic malignancies develop following acquisition of multiple genetic changes. Despite providing many insights into the way by which given genetic changes contribute to the development of disease, the generation of animal models is often laborious. We show a simplified method that allows the retroviral transduction of(More)
