Bone disease (BD) in multiple myeloma (MM) is because of the activation of osteoclasts and impairment of osteoblast differentiation. Connective tissue growth factor (CTGF) is known to participate in the differentiation of mesenchymal stem cells to committed osteoprogenitor cells. We analysed the concentration of circulating CTGF in 35 MM patients and 22(More)
We investigated the effects of bortezomib (PS-341) and immunomodulatory thalidomide analogs (immunomodulatory compounds; CC-4047, CC-6032, and CC-5013, or lenalidomide) on osteoblast and osteoclast differentiation in vitro using human mesenchymal stem cells (hMSC) to commit to osteoprogenitor cells and peripheral blood mononuclear cells (PBMCs) isolated(More)
We established a myeloma cell line (RPMI8226) with cyclin D1 overexpression in which the transfected cyclin D1 gene was stably expressed. D1 transfectants showed down-regulation of cyclin D2. Cell proliferation analysis did not show any differences among RPMI8226, mock control, and D1 transfectants. The number of S-phase cells increased while the number of(More)
Tumor necrosis factor-alpha (TNF-alpha) induces both rapid onset of apoptosis and monocytic differentiation in HL-60 human myeloid leukemia cells. In this study, we examined the effect of activation of protein kinase C (PKC) in c-Myc protein expression in association with the induction of apoptosis and differentiation in TNF-alpha-treated HL-60 cells.(More)
We analyzed both morphologic and phenotypic findings of myeloma cells before and after chemotherapy in 21 patients with multiple myeloma. The morphologic analysis was based on the Greipp classification, and phenotypic analysis was performed by 3-color flow cytometry using the CD38 plasma gating method (Marrow plasma 38). Results with flow cytometry using a(More)
A 71-year-old man with high fever and enlargement of the bilateral submandibular, cervical and inguinal lymph nodes was hospitalized at Hiroshima University Hospital. The immunohistochemical and pathologic findings from the biopsy specimens led to the diagnosis of angioimmunoblastic T-cell lymphoma (AILT) with a cluster of CD20-positive cells. Flow(More)
