H2S Is a Potential Universal Reducing Agent for Prx6‐Type Peroxiredoxins

Advanced Science, EarlyView.
We report the identification of H2S as reducing agent for Prx6‐type peroxiredoxins. In contrast to common physiological reducing agents of other peroxiredoxins, HS− is small enough to access the active site of oxidized Prx6‐type enzymes in the fully‐folded protein conformation.

Paradoxical roles of antioxidant enzymes:Basic mechanisms and health implications [PDF]

, 2015
Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are generated from aerobic metabolism, as a result of accidental electron leakage as well as regulated enzymatic processes.

Polyamine-mediated ferroptosis amplification acts as a targetable vulnerability in cancer

Nature Communications
Targeting ferroptosis, an iron-dependent form of regulated cell death triggered by the lethal overload of lipid peroxides, in cancer therapy is impeded by our limited understanding of the intersection of tumour’s metabolic feature and ferroptosis ...

Secondary Necrosis Following Caspase‐Activation can Occur Independently of Gasdermin E

Advanced Science, EarlyView.
Secondary necrosis follows apoptosis, but its mechanism is unclear. This study shows that although gasdermin E is cleaved during this process, it is not required for membrane rupture. Across multiple models, secondary necrosis occurred regardless of gasdermin E presence, challenging prior claims and redefining the understanding of how apoptotic cells ...

Neuropilin-1 Controls Endothelial Homeostasis by Regulating Mitochondrial Function and Iron-Dependent Oxidative Stress. [PDF]

, 2018
The transmembrane protein neuropilin-1 (NRP1) promotes vascular endothelial growth factor (VEGF) and extracellular matrix signaling in endothelial cells (ECs).

Cell cycle arrest induces lipid droplet formation and confers ferroptosis resistance

Nature Communications
How cells coordinate cell cycling with cell survival and death remains incompletely understood. Here, we show that cell cycle arrest has a potent suppressive effect on ferroptosis, a form of regulated cell death induced by overwhelming lipid peroxidation

Iron Overload Mediates the Differential Cell Fate of Astrocytes from Neurons and Its Regulatory Mechanisms in Ischemic Stroke

Advanced Science, EarlyView.
Upon ischemia/reperfusion‐induced iron overload condition, neurons and astrocytes exhibit similar oxidative stress changes but opposite alterations in endogenous antioxidant defense mechanisms, leading to divergent ferroptotic outcomes. The iron deposition and neuronal loss are increased within the perilesional cortex of stroke patients ...

Role of Mitochondria in Ferroptosis and Its Relationship to Tumors

Chinese Journal of Lung Cancer
Ferroptosis is a recently discovered form of cell death that is distinct from apoptosis, characterized primarily by the accumulation of intracellular iron and increased levels of lipid peroxidation.
