TLDR
How the mitochondria has a key role in regulating the interplay between redox homeostasis and metabolism within tumor cells is described, and the potential therapeutic use of agents that directly or indirectly block metabolism is discussed.Abstract:
Tumor cells harbor genetic alterations that promote a continuous and elevated production of reactive oxygen species. Whereas such oxidative stress conditions would be harmful to normal cells, they facilitate tumor growth in multiple ways by causing DNA damage and genomic instability, and ultimately, by reprogramming cancer cell metabolism. This review outlines the metabolic-dependent mechanisms that tumors engage in when faced with oxidative stress conditions that are critical for cancer progression by producing redox cofactors. In particular, we describe how the mitochondria has a key role in regulating the interplay between redox homeostasis and metabolism within tumor cells. Last, we will discuss the potential therapeutic use of agents that directly or indirectly block metabolism.read more

A Model of Redox Kinetics Implicates the Thiol Proteome in Cellular Hydrogen Peroxide Responses
TL;DR: A network model of H( 2)O(2) clearance that includes the pseudo-enzymatic oxidative turnover of protein thiols, the enzymatic actions of catalase, glutathione peroxidase, peroxiredoxins, and glutaredoxin, and the redox reactions of thioredoxin and glutathionylated adducts is introduced.

Gain of Nrf2 Function in Non-Small-Cell Lung Cancer Cells Confers Radioresistance
TL;DR: It is established that constitutive activation of Nrf2 protects against ionizing radiation toxicity and confers radioresistance, and targeting NRF2 activity in radioresistant tumors could be a promising strategy to circumvent radiores resistance.

TL;DR: Modulation of GA function may be a new therapeutic target for cancer treatment after it was demonstrated to be regulated by oncogenes and to support tumor cell growth.

TL;DR: It is reported that the tumorigenic phenotype associated with complex I dysfunction could be reversed by introducing a yeast NADH quinone oxidoreductase (NDI1) gene, which bypassed the defective complex I and restored oxidative phosphorylation in the host cells.

TL;DR: MitoQ treatment led to irreversible inhibition of clonogenic growth of breast cancer cells through a combination of autophagy and apoptotic cell death mechanisms and should be further evaluated for novel anticancer activity.
