Erythrocyte SOD1 activity, but not SOD1 polymorphisms, is associated with ICU mortality in patients with septic shock

Free Radical Biology and Medicine, 2018
The objective of our study was to evaluate the influence of the superoxide dismutase 1 (SOD1) polymorphisms on erythrocyte SOD1 activity and the mortality of patients with septic shock. We prospectively evaluated 175 patients aged over 18 years with septic shock upon ICU admission. However, 38 patients were excluded. Thus, 137 patients were enrolled in

SOD2 to SOD1 Switch in Breast Cancer [PDF]

Journal of Biological Chemistry, 2014
Cancer cells are characterized by elevated levels of reactive oxygen species, which are produced mainly by the mitochondria. The dismutase SOD2 localizes in the matrix and is a major antioxidant. The activity of SOD2 is regulated by the deacetylase SIRT3.

Redox Cascade in Chicken Skeletal Muscle: SELENOT Suppression in Selenium Deficiency Triggers Disulfidptosis via mtROS‐NADPH Dysregulation

Advanced Science, EarlyView.
Se deficiency downregulates SELENOT, disrupting mitochondrial function and elevating mtROS to induce glucose metabolic reprogramming, NADPH depletion, cysteine accumulation, and disulfidptosis‐mediated actin cytoskeleton collapse in chicken skeletal muscle.

Anti‐Swelling Hydrogel Combined With Nucleus Pulposus Cell Exosomes and Senolytic Drugs Efficiently Repair Intervertebral Disc Degeneration

Advanced Science, EarlyView.
In this study, a bifunctional anti‐swelling hydrogel system is developed, which encapsulated anti‐senescence drugs quercetin, dasatinib, nucleus pulposus‐derived exosomes (NP‐Exo) to clear senescent nucleus pulposus cells, regulate the inflammatory disc microenvironment, and enhance nucleus pulposus cells activity, ultimately promoting the repair of ...

Evaluating the role of the Hippo pathway in the onset and disease progression of the SOD1 mouse model of amyotrophic lateral sclerosis [PDF]

, 2016
The Hippo pathway is a cell signaling pathway involved in organ size regulation and tumorigenesis in mammals. This pathway regulates the activity of Yes-associated protein (YAP), a transcriptional coactivator which binds to the transcription factor TEAD ...

Screening of the transcriptional regulatory regions of vascular endothelial growth factor receptor 2 (VEGFR2) in amyotrophic lateral sclerosis [PDF]

, 2007
Background Vascular endothelial growth factor (VEGF) has neurotrophic activity which is mediated by its main agonist receptor, VEGFR2. Dysregulation of VEGF causes motor neurone degeneration in a mouse model of amyotrophic lateral sclerosis (ALS), and

SOD1 Lysine 123 Acetylation in the Adult Central Nervous System

Frontiers in Cellular Neuroscience, 2016
Superoxide dismutase 1 (SOD1) knockout (Sod1-/-) mice exhibit an accelerated aging phenotype. In humans, SOD1 mutations are linked to familial amyotrophic lateral sclerosis (ALS), and post-translational modification (PTM) of wild-type SOD1 has been ...

Features of wild-type human SOD1 limit interactions with misfolded aggregates of mouse G86R Sod1 [PDF]

Molecular Neurodegeneration, 2013
AbstractMutations in the gene encoding superoxide dismutase 1 (SOD1) account for about 20% of the cases of familial amyotrophic lateral sclerosis (fALS). It is well established that mutations in SOD1, associated with fALS, heighten the propensity of the protein to misfold and aggregate.
