英文摘要
The aim of this study is to clarify the mechanism of oncogesis by TAF-I-CAN generated by chromosomal translocation and associated with undifferentiated acute myeloma. In TAF-I-CAN transgenic mice that we constructed, haemopoietic cell differentiation was blocked. When TAF-I-CAN in the cell that had been once transformed by TAF-I-CAN was eliminated, some oncogenic phenotypes were not cancelled, suggesting that an epigenetic change(s) is involved in cell transformation by TAF-I-CAN. TAF-I-CAN was found to inhibit NF-κB- and CBP-mediated transcription by their being mislocalized and squelched, respectively, by TAF-I-CAN. In addition, we found the possibility that RAG proteins and their cryptic signal sequences are involved in translocation for generation of TEL-AML1.
