the absence of IP3R2 led to increased innate immunity, which may contribute to the decreased survival of the SOD1(G93A) mice.our data indicate that IP3R2 protects against the negative effects of inflammation, suggesting that the increase in IP3R2 expression in ALS patients is a protective response.

we showed that, in the absence of ERalpha (show ESR1 Proteins), G93A-SOD1 failed to activate OMI (show HTRA2 Proteins) and the proteasome, confirming the ERalpha (show ESR1 Proteins) dependence of the response. Taken together, these results demonstrate the IMS-UPRmt activation in SOD1 familial Amyotrophic lateral sclerosis , and suggest that sex differences in the disease phenotype could be linked to differential activation of the ERa axis of the IMS-UPRmt
The cross-sectional area of the pial arteriolar wall was increased in SOD1 deficiency, and a hyperhomocysteinemic diet sensitized SOD1-deficient mice to this hypertrophic effect. Analysis of of the vascular wall demonstrated a increase in the content of smooth muscle and elastin (show ELN Proteins). We conclude that superoxide is a driver of both cerebral vascular hypertrophy and vasomotor dysfunction in a model of hyperhomocysteinemia.

The results show that the docking of the electrostatic loop to the rest of SOD1 plays a role in amyotrophic lateral sclerosis (ALS (show IGFALS Proteins)) pathogenesis, in support of that structure acting as a solvent barrier for the metal site. The results provide a unified pathogenic mechanism for five different ALS (show IGFALS Proteins)-linked mutations of SOD1.
SOD1 is the seeding particle responsible for the spread of SOD1-familial amyotrophic lateral sclerosis neurodegeneration from its initial onset site

study thus implies that the WT and mutant SOD1 indeed converge on a common mechanism for gain of cytotoxicity by abnormally interacting with membranes. Moreover, any genetic/environmental factors which can delay or impair its maturation might act to transform SOD1 into cytotoxic forms with the acquired capacity to abnormally interact with membranes.
Data suggest that multiple non-native species of misfolded SOD1 may exist in the SOD1(G93A) rat model, some of which are associated with mitochondrial damage, highlighting that variable potency/toxicity of different SOD1 species is possible even when only one SOD1 mutation is present.
SOD1 is one of the most commonly mutated genes in ALS.
superoxide dismutase function of SOD1 might not be required to preserve DNA integrity in motor neurons, at least when the function of TDP-43 (show TARDBP Proteins) is unaltered

The protein encoded by this gene binds copper and zinc ions and is one of two isozymes responsible for destroying free superoxide radicals in the body. The encoded isozyme is a soluble cytoplasmic protein, acting as a homodimer to convert naturally-occuring but harmful superoxide radicals to molecular oxygen and hydrogen peroxide. The other isozyme is a mitochondrial protein. Mutations in this gene have been implicated as causes of familial amyotrophic lateral sclerosis. Rare transcript variants have been reported for this gene.
