Multiple myeloma (MM) is an incurable haematological malignancy characterised by the proliferation of mature antibody-secreting plasma B cells in the bone marrow. MM can arise from initiating translocations, of which the musculoaponeurotic fibrosarcoma (MAF) family is implicated in ∼5%. MMs bearing Maf translocations are of poor prognosis. These translocations are associated with elevated Maf e...
OBJECTIVE ADAMTS (a disintegrin and metalloproteinase with thrombospondin type-1 motif) zinc metalloproteinases are important during the synthesis and breakdown of cartilage extracellular matrix. ADAMTS-12 is up-regulated during in vitro chondrogenesis and embryonic limb development; however, the regulation of ADAMTS-12 expression in cartilage remains unknown. The transcription factor c-Maf is ...
The oncogene c-maf is translocated in approximately 5%-10% of multiple myelomas. Unexpectedly, we observed c-maf expression in myeloma cell lines lacking c-maf translocations and in 50% of multiple myeloma bone marrow samples. By gene expression profiling, we identified three c-maf target genes: cyclin D2, integrin beta7, and CCR1. c-maf transactivated the cyclin D2 promoter and enhanced myelom...
c-Maf, a leucine zipper-containing transcription factor, is involved in the t(14;16)(q32;q23) translocation found in 5% of myelomas. A causal role for c-Maf in myeloma pathogenesis has been proposed, but data on c-Maf protein expression are lacking. We therefore studied the expression of c-Maf protein by immunohistochemical analysis in myelomas and in a wide variety of hematopoietic tissue. c-M...
c-Maf translocation or overexpression has been observed in human multiple myeloma. Although c-maf might function as an oncogene in multiple myeloma, a role for this gene in other cancers has not been shown. In this study, we have found that mice transgenic for c-Maf whose expression was direct to the T-cell compartment developed T-cell lymphoma. Moreover, we showed that cyclin D2, integrin beta...
Multiple myeloma (MM) is a currently incurable neoplasm of terminally differentiated B cells. The translocation and/or overexpression of c-MAF have been observed in human MM. Although c-MAF might function as an oncogene in human MM, there has been no report thus far describing the direct induction of MM by c-MAF overexpression in vivo. In this study, we have generated transgenic (TG) mice that ...
The erythroblastic island was ultrastructurally identified as a common organizational unit of bone marrow more than 50 years ago.2 Erythroblastic islands are composed of erythroblasts, at various stages of maturation, and a central macrophage. The central macrophage supports erythroid cell survival and proliferation through intercellular signaling, and facilitates enucleation.3 Along this line,...
The importance of the large Maf transcription factor family has been investigated in lens development in the chick, Xenopus and mammals. Previously we reported that c-maf-deficient mice exhibit severe defects in lens fibre cells. Here, we report the roles of other large Mafs, MafA/L-Maf and MafB, during mouse lens development. MafA/L-Maf and MafB were expressed in lens epithelial cells and fibr...
The moving average filter-based phase-locked loop (MAF-PLL) can obtain grid synchronization signals accurately under adverse conditions with a large amount of harmonics due to the high filtering capability MAF. However, MAF-PLL cannot achieve fast dynamic response in case frequency drift, phase angle steps, and unbalanced voltage sag. MAF is essentially an FIR filter, its performance hard be ad...
