Abstract:
Multiple myeloma is an incurable malignant disease characterized by proliferation of clonal plasma cells in the bone marrow.About 90% of the patients with multiple myeloma develop myeloma bone disease(MBD),which seriously affects the quality of life and prognosis of the patients.Traditional therapies for MBD include bisphosphonates,radiotherapy,and surgery.The recent studies have confirmed that the receptor activator of nuclear factor κB ligand (RANKL)-receptor activator of nuclear factor κB(RANK) signaling pathway plays a key role in MBD,providing a new therapeutic target for MBD.This review summarized the role of RANKL-RANK signaling pathway in the pathogenesis of MBD and the advance in the targeted therapy.
Insights
Multiple myeloma patients often develop bone disease (MBD). The RANKL-RANK pathway is key in MBD, offering a new target for therapies to improve patient outcomes.
Area of Science:
- Oncology
- Bone Biology
- Molecular Signaling
Background:
- Multiple myeloma is a fatal plasma cell malignancy.
- Myeloma bone disease (MBD) affects 90% of patients, impacting quality of life and prognosis.
- Current MBD treatments include bisphosphonates, radiotherapy, and surgery.
Purpose of the Study:
- To review the role of the receptor activator of nuclear factor κB ligand (RANKL)-receptor activator of nuclear factor κB (RANK) signaling pathway in MBD pathogenesis.
- To summarize advances in targeted therapies for MBD.
Main Methods:
- Literature review of studies on the RANKL-RANK pathway in multiple myeloma and MBD.
- Analysis of current and emerging therapeutic strategies targeting this pathway.
Main Results:
- The RANKL-RANK signaling pathway is confirmed to play a critical role in the development of MBD.
- Targeting the RANKL-RANK pathway presents a promising therapeutic avenue for MBD.
Conclusions:
- Understanding the RANKL-RANK pathway's role is crucial for developing novel MBD treatments.
- Targeted therapies offer new hope for managing MBD in multiple myeloma patients.
