Abstract:
Reactive Oxygen Species or "ROS" encompass several molecules derived from oxygen that can oxidize other molecules and subsequently transition rapidly between species. The key roles of ROS in biological processes are cell signaling, biosynthetic processes, and host defense. In cancer cells, increased ROS production and oxidative stress are instigated by carcinogens, oncogenic mutations, and importantly, metabolic reprograming of the rapidly proliferating cancer cells. Increased ROS production activates myriad downstream survival pathways that further cancer progression and metastasis. In this review, we highlight the relation between ROS, the metabolic programing of cancer, and stromal and immune cells with emphasis on and the transcription machinery involved in redox homeostasis, metabolic programing and malignant phenotype. We also shed light on the therapeutic targeting of metabolic pathways generating ROS as we investigate: Orlistat, Biguandes, AICAR, 2 Deoxyglucose, CPI-613, and Etomoxir.
Insights
Reactive Oxygen Species (ROS) fuel cancer progression by altering cell metabolism and activating survival pathways. Targeting ROS-generating metabolic pathways offers a promising therapeutic strategy for cancer treatment.
Area of Science:
- Biochemistry
- Oncology
- Cell Biology
Background:
- Reactive Oxygen Species (ROS) are crucial for cell signaling, biosynthesis, and host defense.
- Cancer cells exhibit increased ROS production due to carcinogens, mutations, and metabolic reprogramming.
- Elevated ROS levels promote cancer progression and metastasis via downstream survival pathways.
Purpose of the Study:
- To review the intricate relationship between ROS, cancer cell metabolism, and the tumor microenvironment.
- To explore the role of transcription machinery in maintaining redox homeostasis and malignant phenotypes.
- To investigate therapeutic strategies targeting ROS-generating metabolic pathways in cancer.
Main Methods:
- Literature review focusing on the interplay between ROS, cancer metabolism, and therapeutic interventions.
- Analysis of key metabolic pathways and transcription factors involved in redox balance.
- Examination of existing and emerging drugs targeting cancer metabolism.
Main Results:
- Increased ROS production is a hallmark of cancer, driven by metabolic reprogramming.
- ROS signaling pathways are critical for cancer cell survival, proliferation, and metastasis.
- Metabolic interventions targeting ROS production show potential as anti-cancer therapies.
Conclusions:
- Understanding the ROS-metabolism axis is vital for developing novel cancer treatments.
- Targeting metabolic pathways that generate ROS presents a viable therapeutic avenue.
- Further research into drugs like Orlistat, Biguanides, AICAR, 2-Deoxyglucose, CPI-613, and Etomoxir is warranted.

Cancer Therapies
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...
