Fibrotic response induced by angiotensin-II requires NAD(P)H oxidase-induced reactive oxygen species (ROS) in skeletal muscle cells
(2011)
Fibrotic disorders are typified by excessive connective tissue and extracellular matrix (ECM) deposition that precludes normal healing processes in different tissues. Angiotensin-II (Ang-II) is involved in the fibrotic ...
Reactive Oxygen Species Mediated Activation of a Dormant Singlet Oxygen Photosensitizer: From Autocatalytic Singlet Oxygen Amplification to Chemicontrolled Photodynamic Therapy
(American Chemical Society, 2016-01)
Here we show the design, preparation, and characterization of a dormant singlet oxygen (1O2) photosensitizer that is activated upon its reaction with reactive oxygen species (ROS), including 1O2 itself, in what constitutes ...
From birth to death: a role for reactive oxygen species in neuronal development
(Elsevier, 2018-08)
Historically, ROS have been considered toxic molecules, especially when their intracellular concentration reaches high values. However, physiological levels of ROS support crucial cellular processes, acting as second ...
Production of reactive oxygen species in peanut nodules
(Communications in Plant Sciences, 2013-03)
In this study, it was investigated the reactive oxygen species (ROS) production in peanut nodules at three peanut growth stages (R): R1 (flowering), R4 (full pod) and R6 (full seed). Analysis of ROS production showed that ...
Blue-light dependent reactive oxygen species formation by Arabidopsis cryptochrome may define a novel evolutionarily conserved signaling mechanism
(Wiley Blackwell Publishing, Inc, 2015-06)
Cryptochromes are widespread blue-light absorbing flavoproteins with important signaling roles. In plants they mediate de-etiolation, developmental and stress responses resulting from interaction with downstream signaling ...
Scavenging activity on reactive oxygen species with biological relevance by the Brazilian non-conventional spice Varronia curassavica
(Elsevier, 2022-01-18)
Varronia curassavica Jacq. is a Non-Conventional Edible Plant (spice) commonly found in Brazil used in folk medicine as anti-inflammatory. The present study aimed to investigate the in vitro antioxidant activity of the ...
Reactive oxygen species generated by NADPH oxidase are involved in neurodegeneration in the pilocarpine model of temporal lobe epilepsy
(ELSEVIER IRELAND LTD, 2010)
Reactive oxygen species (ROS) appear to be involved in several neurodegenerative disorders. We tested the hypothesis that oxidative stress could have a role in the hippocampal neurodegeneration observed in temporal lobe ...
Singlet oxygen quenching and radical scavenging capacities of structurally-related flavonoids present in Zuccagnia punctata Cav.
(Taylor & Francis LtdAbingdonInglaterra, 2009)
Mitochondrial reactive oxygen species (ROS) as signaling molecules of intracellular pathways triggered by the cardiac renin-angiotensin II-aldosterone system (RAAS)
(Frontiers, 2013-05)
Mitochondria represent major sources of basal reactive oxygen species (ROS) production of the cardiomyocyte. The role of ROS as signaling molecules that mediate different intracellular pathways has gained increasing interest ...
