Abstract:
Multiple myeloma (MM) is the second most common hematological cancer that has no cure. Although currently there are several novel drugs, most MM patients experience drug resistance and disease relapse. The results of previous studies suggest that aberrant mitochondrial function may contribute to tumor progression and drug resistance. Mitochondrial DNA mutations and metabolic reprogramming have been reported in MM patients. Several preclinical and clinical studies have shown encouraging results of mitochondria-targeting therapy in MM patients. In this review, we have summarized our current understanding of mitochondrial biology in MM. More importantly, we have reviewed mitochondrial targeting strategies in MM treatment.
Insights
Multiple myeloma (MM) treatment faces challenges from drug resistance and relapse. Targeting mitochondria, crucial for cancer cell function, offers a promising therapeutic strategy for this incurable hematological cancer.
Area of Science:
- Hematology
- Oncology
- Mitochondrial Biology
Background:
- Multiple myeloma (MM) is a prevalent, incurable blood cancer.
- Drug resistance and disease relapse are significant challenges in MM patient care.
- Mitochondrial dysfunction is increasingly implicated in MM progression and therapeutic failure.
Purpose of the Study:
- To review the current understanding of mitochondrial biology in multiple myeloma.
- To explore mitochondria-targeting strategies as a therapeutic approach for MM.
Main Methods:
- Literature review of preclinical and clinical studies.
- Analysis of research on mitochondrial DNA mutations and metabolic reprogramming in MM.
- Synthesis of findings on mitochondria-targeting therapies in MM.
Main Results:
- Aberrant mitochondrial function, including DNA mutations and metabolic shifts, is observed in MM.
- Mitochondria-targeting therapies have shown promising preclinical and clinical results in MM.
- Understanding mitochondrial biology is key to developing novel MM treatments.
Conclusions:
- Mitochondria play a critical role in MM pathogenesis and drug resistance.
- Targeting mitochondria represents a viable and promising therapeutic avenue for multiple myeloma.
- Further research into mitochondrial biology can lead to improved MM treatment strategies.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
