  14. Certain SOD1 mutants, viz. His80Arg and Asp83Gly, were recognized that were more damaging to the Zn binding loop than all other mutants, leading to a loss of Zn binding with altered coordination of the Zn ion. Furthermore, the conformational stability, compactness, and secondary structural alteration of the His80Arg and Asp83Gly mutants were monitored using distinct parameters. PMID: 28271284

  27. Study shows that in senile cataracts, SOD1 expression decreased significantly. Both H3 and H4 were deacetylated at -600 bp of the SOD1 promoter of cataract lenses, and hypoacetylated at -1500, -1200, and -900 bp.

PMID: 26069299
  45. Slowly upper and lower motor neuron degeneration, even with non-motor clinical features, should prompt a sequencing of SOD1 PMID: 27892702
  46. research demonstrated that erysipelas infection predisposition and its clinical characteristics are affected by age, sex and SNPs found in SOD1, SOD2, and catalase genes; presence of SOD1 G7958 alleles was linked to erysipelas' predisposition; G and A alleles of SOD1 G7958A individually were associated with lower limbs and higher body part localizations of the infection, respectively PMID: 28512644

Gelsolin enhances the invasive capacity of colon cancer cells via elevating intracellular superoxide (O2.-) levels by interacting with Cu/ZnSOD, and gelsolin gene expression positively correlates with urokinase plasminogen activator (uPA), an important matrix-degrading protease invovled in cancer invasion. PMID: 27391159
  50. The observation that beta-strand 5 is among the first to unfold here, but the last to unfold in simulations of loop-truncated SOD1, could imply the existence of an evolutionary compensation mechanism, which would stabilize beta-strands flanking long loops against their entropic penalty by strengthening intramolecular interactions.
