Reactive oxygen species (ROS) homeostasis and redox regulation in cellular signaling
TLDR
This review focuses on the molecular mechanisms through which ROS directly interact with critical signaling molecules to initiate signaling in a broad variety of cellular processes, such as proliferation and survival, ROS homeostasis and antioxidant gene regulation, mitochondrial oxidative stress, apoptosis, and aging.About:

Mitochondrial Reactive Oxygen Species (ROS) and ROS-Induced ROS Release
TL;DR: The mechanism of mitochondrial RIRR highlights the central role of mitochondria-formed ROS, and all of the known ROS-producing sites and their relevance to the mitochondrial ROS production in vivo are discussed.

Generation and Detection of Reactive Oxygen Species in Photocatalysis
Yoshio Nosaka,Atsuko Y. Nosaka +1 more
TL;DR: The detection methods and generation mechanisms of the intrinsic reactive oxygen species (ROS) in photocatalysis were surveyed comprehensively and the major photocatalyst used in heterogeneous photocatalytic systems was found to be TiO2.
Journal ArticleDOI
Reactive oxygen species generating systems meeting challenges of photodynamic cancer therapy
TL;DR: The current status and possible opportunities for ROS generation for cancer therapy are summarized and it is hoped this review will spur pre-clinical research and clinical practice for ROS-mediated tumour treatments.

The ATM protein kinase: regulating the cellular response to genotoxic stress, and more
Yosef Shiloh,Yael Ziv +1 more
TL;DR: Evidence suggests that ATM-mediated phosphorylation has a role in the response to other types of genotoxic stress and it has become apparent that ATM is active in other cell signalling pathways involved in maintaining cellular homeostasis.
Journal ArticleDOI
Ferroptosis: mechanisms, biology and role in disease.
TL;DR: In this paper, the authors provide a critical analysis of the current molecular mechanisms and regulatory networks of ferroptosis, the potential physiological functions of the potential therapeutic roles, and its pathological roles, together with a potential for therapeutic targeting.

Targeting cancer cells by ROS-mediated mechanisms: a radical therapeutic approach?
TL;DR: It is argued that modulating the unique redox regulatory mechanisms of cancer cells might be an effective strategy to eliminate these cells.
Journal ArticleDOI
Mitochondria, Oxidants, and Aging
TL;DR: The evidence is reviewed that both supports and conflicts with the free radical theory of aging and the growing link between mitochondrial metabolism, oxidant formation, and the biology of aging is examined.
Journal ArticleDOI
Oxidative stress and diabetic complications
TL;DR: Athrosclerosis and cardiomyopathy in type 2 diabetes are caused in part by pathway-selective insulin resistance, which increases mitochondrial ROS production from free fatty acids and by inactivation of antiatherosclerosis enzymes by ROS.

An nrf2/small maf heterodimer mediates the induction of phase ii detoxifying enzyme genes through antioxidant response elements
Ken Itoh,Tomoki Chiba,Satoru Takahashi,Tetsuro Ishii,Kazuhiko Igarashi,Yasutake Katoh,Tatsuya Oyake,Norio Hayashi,Kimihiko Satoh,Ichiro Hatayama,Masayuki Yamamoto,Yo-ichi Nabeshima +11 more
TL;DR: It is demonstrated that Nrf2 is essential for the transcriptional induction of phase II enzymes and the presence of a coordinate transcriptional regulatory mechanism for phase II enzyme genes and the nrf2-deficient mice may prove to be a very useful model for the in vivo analysis of chemical carcinogenesis and resistance to anti-cancer drugs.

Keap1 represses nuclear activation of antioxidant responsive elements by Nrf2 through binding to the amino-terminal Neh2 domain
Ken Itoh,Nobunao Wakabayashi,Yasutake Katoh,Tetsuro Ishii,Kazuhiko Igarashi,James Douglas Engel,James Douglas Engel,Masayuki Yamamoto +7 more
TL;DR: It is postulate that Keap1 and Nrf2 constitute a crucial cellular sensor for oxidative stress, and together mediate a key step in the signaling pathway that leads to transcriptional activation by this novel NRF2 nuclear shuttling mechanism.
