Gene References into Functions
  1. MnSOD deficiency exacerbated the mitochondrial rate of reactive oxygen species (ROS) production and myocardial oxidative stress in Chagas disease. PMID: 30044789
  2. Quiescence is initiated by the prion protein (PrP) and maintained through downstream increases in the expression and activity of superoxide dismutase-2 (SOD2) that reduces mitochondrial superoxide. PMID: 29574582
  3. Melatonin promoted MnSOD and SIRT1 expression, which successfully ameliorated busulfan-induced SSC apoptosis caused by high concentrations of ROS and p53 PMID: 28027652
  4. deletion of intestinal SOD2 gene in mice results in increased susceptibility to colitis PMID: 28401939
  5. SOD2 expression is ATM- and RelA-dependent, ATM knockdown renders cells sensitive to pro-oxidant exposure, and SOD mimetics partially rescue this sensitivity. Mice with germline deletion of Atm fail to develop mature mammary glands, but using a conditional knockout approach, we determined that Atm deletion significantly diminished the expression of Sod2. PMID: 28849346
  6. Enhanced mitochondrial oxidative stress under hyperlipidemic conditions in aging induces plaque instability, in part by increasing smooth muscle cell apoptosis, necrotic core expansion, and matrix degradation in Sod2/ApoE knockout mice. PMID: 29079564
  7. Deletion of SOD2 increases mitochondrial reactive oxygen species but does not influence platelet function. PMID: 28771279
  8. This study reveals a novel model regulating cardiomyocyte apoptosis which is composed of miR-23a and MnSOD. PMID: 28756653
  9. data showed that Klotho protects Tac-induced oxidative stress by negatively regulating the PI3K/AKT pathway and subsequently enhancing FoxO3a-mediated MnSOD expression. PMID: 28771227
  10. Moderate MnSOD and/or catalase overexpression in desmin-null hearts leads to a marked decrease in intracellular reactive oxygen species, ameliorates mitochondrial and other ultrastructural defects, minimizes myocardial degeneration and leads to a significant improvement of cardiac function. PMID: 28629836

  12. SOD2 overexpression blocks maternal diabetes-induced oxidative stress and ER stress, and reduces the incidence of NTDs in embryos exposed to maternal diabetes PMID: 27130031
  13. the regulation of mitochondrial ROS by SOD2 and Sirt3 plays an important role in fine-tuning the Osteoclast differentiation program. PMID: 27540894

  15. On normal salt diet, renal CuZnSOD and ECSOD proteins were similar but renal MnSOD was lower in hGRK4g486V than Non-T mice and remained low on high salt diet. hGRK4gammawild-type mice were normotensive and hGRK4g142V mice were hypertensive but both were salt-resistant and in normal redox balance. Chronic tempol treatment partially prevented the salt-sensitivity of hGRK4g486V mice. PMID: 28189851
  16. when mice were challenged with chronic, peripheral infusion of AngII, only the MnSOD knock-down confined to the SFO, and not the periphery, demonstrated an increased sensitization and potentiated hypertension. In complementary experiments, over-expressing MnSOD in the SFO significantly decreased blood pressure in response to chronic AngII. PMID: 27889641

  18. We investigated the role of Mn-SOD in NIHL by examining the extent of hearing loss and hair cell damage after noise exposure in C57BL/6 wild-type (WT) mice and Mn-SOD heterozygous knockout (HET) mice. Mean ABR thresholds were significantly worse on post-noise exposure days 7 and 14 in HET mice compared with WT mice. Outer hair cell damage was significantly greater in all cochlear turns in HET mice compared with WT mice. PMID: 28163078
  19. Data suggest that negative regulatory effect of Sirt3 on Nlrp3 inflammasome assembly in macrophages due to prolonged fasting occurs via Sirt3-mediated deacetylation of mitochondrial Sod2, leading to Sod2 activation; prolonged fasting blunts inflammasomes in wild-type mice but not in Sirt3 knock-out mice. (Sirt3 = sirtuin 3; Nlrp3 = NLR family, pyrin domain containing 3 protein; Sod2 = superoxide dismutase 2) PMID: 28584055
