Other interactions of Gpx1

  • This study reports evidence of both common sites of Gpx1 and Gpx2 expression in rat colon and sites that are exclusive to each isoform [25].
  • In conclusion, the protective effect of SnCl2 on K2Cr2O7-induced nephrotoxicity is associated with HO-1 induction and not with other antioxidant enzymes (Cu,Zn-SOD, Mn-SOD, GPx, GR, and CAT) and SnCl2 has a preventive and not a therapeutic effect on renal damage induced by K2Cr2O7 [39].
 

Analytical, diagnostic and therapeutic context of Gpx1

  • Semi-quantitative PCR performed previously demonstrated RNA expression of Gpx1 and Gpx2 in proximal, transverse and distal colon [25].
  • In rats treated with GM (70 mg/kg/12 h/4 days/s.c.), ARF was evident by the: (i) decrease in creatinine clearance and increase in blood urea nitrogen, (ii) decrease in blood glutathione peroxidase (GPx) activity and increase in urinary excretion of N-acetyl-beta-D-glucosaminidase and total protein, and (iii) necrosis of proximal tubular cells [23].
  • Activities of GPx, SOD and CAT were higher in groups receiving DOX and/or DOX plus melatonin than in control groups [40].
  • Western blot analysis of cytoplasm for GPX and CuZn SOD showed a significant decrease in GPX and CuZn SOD proteins [41].
  • Endotracheal bleomycin administration alone caused significant reductions in catalase activity at 2 days and 2 weeks after treatment, whereas glutathione peroxidase activity increased above control untreated animals at 2 and 4 weeks, respectively [42].
