Signaling Interplay between Bone Marrow Adipose Tissue and Multiple Myeloma cells

Area of Science:

• Oncology
• Cancer Biology
• Endocrinology

Background:

• The Hallmarks of Cancer framework evolved to include eight hallmarks and two characteristics.
• Multiple myeloma (MM) exhibits all established cancer hallmarks and characteristics.
• Bone marrow adipose tissue (BMAT) is an emerging factor in MM oncogenesis and progression.

Purpose of the Study:

• To review the confirmed and hypothetical roles of BMAT in multiple myeloma development and progression.
• To define the characteristics of bone marrow adipocytes and their metabolic activity.
• To explore BMAT's influence on MM through lipids, metabolism, angiogenesis, signaling, and bone disease.

Main Methods:

• Literature review of BMAT's role in MM.
• Definition of bone marrow adipocyte function.
• Analysis of BMAT's influence on MM hallmarks and characteristics.

Main Results:

• BMAT influences MM cell metabolism, immune responses, inflammation, and angiogenesis.
• BMAT affects MM progression via lipids, hypoxia, signaling, and bone remodeling.
• A feedback loop exists between BM adipocytes and MM cells, promoting disease progression.

Conclusions:

• BMAT is a critical, yet understudied, component of the bone marrow microenvironment in MM.
• Targeting BMAT may offer novel therapeutic strategies for MM.
• Further research into BMAT's interactions with MM is essential for developing better treatments.
