| Outline of Final Research Achievements |
Multiple myeloma (MM) is plasma cell neoplasm, which is a tumor of terminally differenced B cell. Though genomic instability is considered as one of the underling mechanisms of the tumor progression, its molecular mechanisms remains to be elucidated. AID and BCL6 has been reported to play a pivotal role in B cell tumors but its role in MM has not been studied. In this study, we showed an abundant expression level of BCL6 in myeloma cells but not AID. We evaluated the role of BCL6 in DNA damage responses. BCL6 negatively regulated the expression of ATM and therefore inhibited the formation of gamma H2AX upon X irradiation, which can lead to genomic instability in the myeloma cell treated with anti cancer drugs and irradiation.
