Immunocompetent mouse models of multiple myeloma

Area of Science:

• Oncology
• Immunology
• Genetics

Background:

• Immunocompetent murine models are essential for advancing multiple myeloma (MM) research.
• Existing models in Balb/c and C57Bl strains offer distinct advantages and limitations.
• Transplantable cell lines facilitate large-scale studies and in vitro genetic manipulation.

Purpose of the Study:

• To highlight the importance of immunocompetent murine models in multiple myeloma research.
• To discuss the utility of various mouse models for studying MM pathogenesis and therapeutics.
• To introduce emerging genetically engineered models for specific MM subtypes.

Main Methods:

• Utilizing transplantable cell lines in immunocompetent mice for large cohort studies.
• Employing in vitro cell culture for genetic modifications.
• Introducing human Cereblon (CRBN) to study immunomodulatory drugs (IMiDs) and proteolysis-targeting chimeras (PROTACs).
• Developing genetically engineered mouse models (GEMMs) targeting key genetic alterations in MM.

Main Results:

• Availability of diverse models allows for comprehensive MM research.
• CRBN introduction enables in vivo studies of IMiDs and cereblon-based PROTACs.
• GEMMs are being developed to recapitulate specific genetic subtypes of human multiple myeloma.

Conclusions:

• Immunocompetent murine models are indispensable tools for multiple myeloma research.
• These models support the investigation of disease mechanisms and the development of novel immunotherapeutics.
• Advancements in model development, including GEMMs, promise deeper insights into MM subtypes.
