3 Catalase is an enzyme that breaks down hydrogen peroxide inside cells. Red blood cells contain catalase.Some dogs have an inherited condition in which catalase is not produced. This condition is known as acatalasi a and it is caused by a mutation in the gene for catalase.(a) Define the...
3′,5′-cyclic guanosine monophosphate (cGMP) and hydrogen peroxide (H2O2) function as the important signaling molecule which promote the lateral root development of Arabidopsis thaliana. In this study, interestingly, application of 8-Br-cGMP (the membrane permeable cGMP analog) promoted the ...
Cranial sutures were visualized using 3% hydrogen peroxide. Following identification of Bregma, a unilateral stereotaxic site was drilled with a 0.5-mm microburr (Fine Science Tools) using coordinates X = +1.5, Y = −2.1 and Z = −2.1). Mice were injected with 2 µl ...
h Limiting other reactive oxygen species (including superoxide and hydrogen peroxide) with TEMPOL did not restore a dilatory response to chemical hypoxia in the Hba1–/– or EC Hba1Δ/Δ groups. i Treating the buffer surrounding the vessels with N2 gas to deoxygenate enabled hypoxic vasodilation...
Hydrogen peroxide (H2O2) has been implicated in many stress conditions. Control of H2O2 levels is complex and dissection of mechanisms generating and relieving H2O2 stress is difficult, particularly in intact plants. We have used transgenic tobacco with approximately 10% wild-type catalase activity to...
The close interaction of peroxisomes, potentially forming a contact site, might serve to exchange metabolites and could also contribute to the degradation of hydrogen peroxide (H2O2) or other ROS (Fig. 5C). A close interaction might be beneficial for creating a tight knit web to capture all ROS...
The enhanced reaction rate for Mn-catalytic reaction on the aerosol surface compared to aqueous reaction is mainly attributed to several differences: the difference between the ion–neutral molecule and ion–ion reactions, which perform differently under high ionic strength; the different reaction space...

Next, we determined the intracellular GSH level because GSH is a major antioxidant molecule that mitigate cellular injury from oxidative stress. As shown in Fig. 4A, SHAH treatment under normal condition showed no effect on the intracellular GSH level. However, H2O2 treatment resulted in the deplet...
