Metabolic Flexibility: Targeting Mitochondrial Dynamics in Cancer Therapy

Abstract

Abstract Various types of cancer exhibit distinct sensitivities to anticancer drugs, reflecting their unique developmental pathways. Exploiting mitochondrial dysfunction in cancer cells presents novel therapeutic opportunities. In recent years, advancements have underscored the significance of oxidative phosphorylation, fatty acid oxidation, and glutamine addiction in cancer cells, shifting attention towards mitochondrial metabolism. The foundation of mitochondrial medicine lies in comprehending targeted mitochondrial therapy and the development of specific mitochondrial drugs. Certain alterations within mitochondrial metabolism lead to the accumulation of oncometabolites, serving as epigenetic regulators, or an increase in reactive oxygen species production, both of which contribute to tumorigenesis. Importantly, the substantial involvement of mitochondrial metabolism in tumorigenesis offers potential avenues for exploiting as strategies for cancer therapy. Integrated pharmacological approaches targeting mitochondrial metabolic pathways are imperative for an effective eradication of tumor masses and a concurrent elimination of small subpopulations of mitochondria. The significance of mitochondria in cancer is undeniable, offering numerous appealing targets for both tailored and personalized cancer therapy.
