Mitochondria in cancer: why mitochondria are a good target for cancer therapy
1School of Medical Science, Griffith University, Southport, Queensland, Australia.
Abstract:
Cancer can be characterized as a state of multifaceted cellular deregulation including control of proliferation and bioenergetics. The latter involves in particular mitochondria, the site of the generation of ATP, essential for the proper cellular function (including proliferation). Mitochondria also contain a variety of proteins that are necessary for the induction/promotion, as well as for the prevention of cell death. Therefore, mitochondria are pivotal in deciding the fate of a cell. In cancer, mitochondria are dysfunctional, which was observed as early as in the 1930s by Otto Warburg. Due to the central role of mitochondria, these organelles, endowed with its own DNA, are a focus of research as possible "culprits" for the malignancy of cancer cells (or at least contributing to this phenotype) and, importantly, as emerging targets for anticancer therapy.
Insights
Mitochondria, crucial for cellular energy and life-or-death decisions, are dysfunctional in cancer. Research highlights their role in cancer development and as potential targets for novel anticancer therapies.
Area of Science:
- Mitochondrial biology
- Cancer cell biology
- Bioenergetics
Background:
- Cancer involves multifaceted cellular deregulation, affecting proliferation and energy production.
- Mitochondria are central to cellular energy (ATP generation) and cell death regulation.
- Mitochondrial dysfunction is a hallmark of cancer, noted since the 1930s.
Purpose of the Study:
- To investigate the role of mitochondria in cancer development.
- To explore mitochondria as potential targets for anticancer therapies.
Main Methods:
- Review of historical and current research on mitochondria in cancer.
- Analysis of mitochondrial involvement in cancer cell proliferation and survival.
Main Results:
- Mitochondria play a pivotal role in determining cell fate.
- Mitochondrial dysfunction contributes to the malignant phenotype of cancer cells.
- Mitochondria are increasingly recognized as therapeutic targets.
Conclusions:
- Mitochondria are key players in cancer biology due to their roles in energy metabolism and cell death.
- Targeting mitochondrial dysfunction presents a promising strategy for developing new cancer treatments.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
