| Research Abstract |
Previously, we have shown that an AP-1 family member, FRA-2, is consistently expressed at high levels in Adult T-cell leukemia/lymphoma (ATLL) and up-regulates the expression of CCR4 as well as that of several proto-oncogenes such as c-Myb, MDM2, and BCL6. Here, we identified an ABC transporter, ABCG2/BCRP, as a target gene of c-Myb in mature T-cell lymphomas including ATLL and cutaneous T-cell lymphomas (CTCLs). We detected the transcripts and proteins of c-Myb and ABCG2/BCRP in ATLL cells. Furthermore, Ko143, a selective ABCG2/BCRP inhibitor, enhanced the antitumor activity of doxorubicin against ATLL cell lines. Taken together, our findings support the notion that the c-Myb-ABCG2/BCRP pathway plays a role in chemoresistance of mature T-cell lymphomas.
