Abstract:
Despite significant improvements in treatment strategies over the past couple of decades, multiple myeloma (MM) remains an incurable disease due to the development of drug resistance. Metabolic reprogramming is a key feature of cancer cells, including MM, and acts to fuel increased proliferation, create a permissive tumour microenvironment, and promote drug resistance. This review presents an overview of the key metabolic adaptations that occur in MM pathogenesis and in the development of resistance to proteasome inhibitors, the backbone of current MM therapy, and considers the potential for therapeutic targeting of key metabolic pathways to improve outcomes.
Insights
Multiple myeloma (MM) is incurable due to drug resistance. Targeting metabolic reprogramming, a key feature in MM pathogenesis and drug resistance, offers potential therapeutic strategies to improve patient outcomes.
Area of Science:
- Oncology
- Cancer Metabolism
- Hematology
Background:
- Multiple myeloma (MM) remains incurable despite treatment advances.
- Drug resistance is a major challenge in managing MM.
- Metabolic reprogramming is crucial for cancer cell survival and progression.
Purpose of the Study:
- To review metabolic adaptations in MM pathogenesis.
- To examine metabolic changes contributing to proteasome inhibitor resistance.
- To explore therapeutic targeting of metabolic pathways in MM.
Main Methods:
- Literature review of metabolic reprogramming in multiple myeloma.
- Analysis of key metabolic pathways in MM.
- Discussion of therapeutic strategies targeting cancer metabolism.
Main Results:
- MM cells exhibit significant metabolic reprogramming.
- Metabolic adaptations drive proliferation and create a supportive tumor microenvironment.
- Altered metabolism contributes to resistance against proteasome inhibitors.
Conclusions:
- Metabolic reprogramming is central to MM development and drug resistance.
- Targeting metabolic pathways presents a promising therapeutic avenue for MM.
- Further research into MM metabolism could improve treatment efficacy.

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
