Abstract

Multiple myeloma (MM) is an incurable B-cell malignancy in which the marrow microenvironment plays a critical role in our inability to cure MM. Marrow stromal cells in the microenvironment support homing, lodging, and growth of MM cells through activation of multiple signaling pathways in both MM and stromal cells. Recently, we identified annexin II (AXII) as a previously unknown factor produced by stromal cells and osteoclasts (OCL) that is involved in OCL formation, HSC and prostate cancer (PCa) homing to the BM as well as mobilization of HSC and PCa cells. AXII expressed on stromal cells supports PCa cell lodgment via the AXII receptor (AXIIR) on PCa cells, but the role of AXII and AXIIR in MM is unknown. In this study, we show that MM cells express AXIIR, that stromal/osteoblast-derived AXII facilitates adhesion of MM cells to stromal cells via AXIIR, and OCL-derived AXII enhances MM cell growth. Finally, we demonstrate that AXII activates the ERK1/2 and AKT pathways in MM cells to enhance MM cell growth. These results demonstrate that AXII and AXIIR play important roles in MM and that targeting the AXII/AXIIR axis may be a novel therapeutic approach for MM.
