We used gene targeting in mice to insert a His(6)-tagged mouse c-Myc cDNA, Myc(His), head to head into the mouse immunoglobulin heavy-chain locus, Igh, just 5' of the intronic enhancer, Emu. The insertion of Myc(His) mimicked both the human t(8;14)(q24;q32) translocation that results in the activation of MYC in human endemic Burkitt lymphomas and the(More)

BACKGROUND Gene-targeted iMycEmu mice that carry a His6-tagged mouse Myc(c-myc)cDNA, MycHis, just 5' of the immunoglobulin heavy-chain enhancer, Emu, are prone to B cell and plasma cell neoplasms, such as lymphoblastic B-cell lymphoma (LBL) and plasmacytoma (PCT). Cell lines derived from Myc-induced neoplasms of this sort may provide a good model system for(More)
BACKGROUND Myc-induced lymphoblastic B-cell lymphoma (LBL) in iMycEmu mice may provide a model system for the study of the mechanism by which human MYC facilitates the initiation and progression of B cell and plasma cell neoplasms in human beings. We have recently shown that gene-targeted iMycEmu mice that carry a His6-tagged mouse Myc cDNA, MycHis, just 5'(More)
The potency of influenza vaccine is determined based on its hemagglutinin (HA) content. In general, single radial immunodiffusion (SRID) assay has been utilized as the standard method to measure HA content. However, preparation of reagents for SRID such as antigen and antibody takes approximately 2~3 months, which causes delays in the development of(More)
Instillation of highly soluble nanoparticles (NPs) into the lungs of rodents can cause acute eosinophilia without any previous sensitizations by the role of dissolved ions. However, whether gradually dissolving NPs can cause the same type of eosinophilia remains to be elucidated. We selected nickel oxide (NiO) as a gradually dissolving NP and evaluated the(More)
Based on increasing interest and demands for nanomaterials in both industrial and academic fields, concerns for their potential toxicity emerged. In order to evaluate their potential toxicity as well as their interaction towards biological substances, it is important to comprehend and to precisely determine their physicochemical properties. In this review,(More)
