Abstract
Multiple myeloma (MM) is the second most prevalent hematological malignancy. Current MM treatment strategies are hampered by systemic toxicity and suboptimal therapeutic efficacy. This study addressed these limitations through the development of a potent MM-targeting chemotherapy strategy, which capitalized on the high binding affinity of alendronate for hydroxyapatite in the bone matrix and the homologous targeting of myeloma cell membranes, termed T-PB@M. The results from our investigations highlight the considerable bone affinity of T-PB@M, both in vitro and in vivo. Additionally, this material demonstrated a capability for drug release triggered by low pH conditions. Moreover, T-PB@M induced the generation of reactive oxygen species and triggered cell apoptosis through the poly(ADP-ribose) polymerase 1 (PARP1)–Caspase-3–B-cell lymphoma-2 (Bcl-2) pathway in MM cells. Notably, T-PB@M preferentially targeted bone-involved sites, thereby circumventing systemic toxic side effects and leading to prolonged survival of MM orthotopic mice. Therefore, this designed target-MM nanocarrier presents a promising and potentially effective platform for the precise treatment of MM.
