(Reaume et al., 1996). Further, some mutants such as SOD1 retain full specific activity (Borchelt et al., The sixth anniversary has just passed since the land1994), while neither the age of onset nor rapidity of mark discovery (Rosen et al., 1993) that mutation in the progression of human disease correlate with dismutase enzyme superoxide dismutase 1 (SOD1) is a primary activity levels (Cudkowi...

The snail Biomphalaria glabrata kills the blood fluke Schistosoma mansoni by a mechanism involving production of hydrogen peroxide, the enzymatic product of cytosolic Cu/Zn superoxide dismutase (SOD1). This enzyme exhibits higher activity in blood cells (hemocytes) from a predominantly resistant strain of B. glabrata than in hemocytes from a susceptible strain. Additionally, B. glabrata SOD1 po...

Mutations of Cu, Zn‐superoxide dismutase (SOD1) gene have been identified in a subset of familial amyotrophic lateral sclerosis (ALS). Conformational change, that is, misfolding, of mutant SOD1 underlies its toxic gain of function for motor neuronal degeneration. Mutant SOD1 is prone to cause oxidative stress through the copper exposed on the protein by misfolding. The protein structure of SOD1...

Amyotrophic lateral sclerosis (ALS) is a progressive adult-onset neurodegenerative disorder characterized by the selective loss of upper and lower motor neurons. Mutations in superoxide dismutase (SOD1) cause about 20 percent of familial ALS which is accompanied by accumulation of misfolded SOD1 onto intracellular organelles. Recently, we identified the 12 kDa macrophage migration inhibitory fa...

Recent studies have revealed that oxidative stress has detrimental effects in several models of neurodegenerative diseases, including subarachnoid hemorrhage (SAH). However, how oxidative stress affects acute brain injury after SAH remains unknown. We have previously reported that overexpression of copper/zinc-superoxide dismutase (SOD1) reduces oxidative stress and subsequent neuronal injury a...

The available evidence from in vitro and in vivo studies is deemed not sufficient to draw conclusions about the potential health effects of static magnetic field (SMF) exposure. Therefore, the aim of the present study was to determine the influence of static magnetic fields and phloretin on the redox homeostasis of human dermal fibroblasts. Control fibroblasts and fibroblasts treated with phlor...

INTRODUCTION It is well established that soy protein diets as well as aerobic exercise could promote antioxidant capacity and consequently reduce free radicals overproduction on brain. However, little is know regarding to the high-protein diets and high intensity exercise on oxidative stress production. The aim of this study was to analyse the effects of high-protein diets and high-intensity ex...

A prion-like mechanism has been developed to explain the observed promotion of amyloid aggregation caused by conversion of structurally intact SOD1 to a misfolded form. Superoxide dismutase [Cu-Zn], or SOD1, is a homo-dimeric protein that functions as an antioxidant by scavenging for superoxide. The misfolding and aggregation of SOD1 is linked to inherited, or familial, amyotrophic lateral scle...
