Ultraviolet irradiation increases green fluorescence of dihydrorhodamine (DHR) 123: false-positive results for reactive oxygen species generation.

TL;DR: It is concluded that UV irradiation oxidizes DHR123 to generate Rhodamine 123 (R123) green fluorescence signal, and that the R123 present in the culture supernatant could give erroneous results in plate reader assays.

The Role of Ca 2+ Imbalance in the Induction of Acute Oxidative Stress and Cytotoxicity in Cultured Rat Cerebellar Granule Cells Challenged with Tetrabromobisphenol A

TL;DR: Ca2+ imbalance and oxidative stress both mediate acute toxicity of TBBPA in CGC, and the co-administration of scavengers with NMDA and ryanodine receptor antagonists provided almost complete neuroprotection.

High Glucose Level Impairs Human Mature Bone Marrow Adipocyte Function Through Increased ROS Production.

TL;DR: Mature BMAds are responsive to changes in glucose and ROS concentrations, which is relevant regarding with their phenotype and function in age- or metabolic disease-related osteoporosis.

Glycosaminoglycan degradation by selected reactive oxygen species.

TL;DR: This work focuses on the ROS-induced degradation of the glycosaminoglycans, one important component of the ECM, and investigates the mechanisms of the reactions of these ROS.
Journal ArticleDOI

Derivation, characterisation and analysis of an adverse outcome pathway network for human hepatotoxicity.

TL;DR: In this article, an AOP network connecting 14 linear AOPs related to human hepatotoxicity, currently available in the AOP-Wiki, was derived according to established criteria and characterized and analyzed with regard to its structure and topological features.

ROS as signalling molecules: mechanisms that generate specificity in ROS homeostasis

TL;DR: The pathways that regulate ROS homeostasis are crucial for mitigating the toxicity of ROS and provide strong evidence about specificity in ROS signalling.

Evaluation of the probe 2',7'-dichlorofluorescin as an indicator of reactive oxygen species formation and oxidative stress.

TL;DR: Data suggest that H2O2-Fe(2+)-derived oxidant is mainly responsible for the nonenzymatic oxidation of DCFH, which remains an attractive probe as an overall index of oxidative stress in toxicological phenomena.
Journal ArticleDOI

Reconciling the chemistry and biology of reactive oxygen species

TL;DR: This review examines how target selectivity and antioxidant effectiveness vary for different oxidants and highlights areas where greater understanding is required on the fate of oxidants generated by cellular NADPH oxidases and on the identification of oxidant sensors in cell signaling.
Journal Article

Flow cytometric studies of oxidative product formation by neutrophils: a graded response to membrane stimulation.

TL;DR: The data indicate that the DCFH oxidation assay is quantitatively related to the oxidative metabolic burst of PMNL, and they strongly suggest that the reaction is mediated by H2O2 generated by the PMNL.
