BUB1B promotes multiple myeloma cell proliferation through CDC20/CCNB axis.


PMID 25698537

Abstract

Multiple myeloma (MM) is the second most common hematopoietic malignancy characterized by plasma cell proliferative disorder. In this study, we disclosed that expression of BUB1B significantly increased in high-risk myeloma patients especially in the most aggressive myeloma genetic subgroups of proliferation. Increased BUB1B expression promotes MM cell proliferation. Mechanism study showed that BUB1B expression was highly correlated to CDC20 and CCNB1/2 expression in MM cells, leading to increased MM cell proliferation. Therefore, BUB1B may be a potential target for MM treatment especially for high-risk MM patients.
