- Abstract
- Objective. Oxidative stress has been implicated in the side-effects caused by haemodialysis (HD) treatment. Design. In the present study we have investigated whether gene expression of the enzymatic defence system provided by cellular glutathione peroxidase (GPx-1), phospholipid glutathione peroxidase (GPx-4), glutathione reductase (GSSG-R), glutathione synthethase (GSH-S), Cu/Zn-superoxide dismutase (SOD-1) and catalase (CAT) is affected by HD. The GPx-1, GPx-4, GSSG-R, GSH-S, SOD-1 and CAT mRNA were determined in white blood cells by quantitative reverse transcriptase-polymerase chain reaction with the LightCycler((R)) instrument and transcription elongation factor-2 as reference gene at the start (SD) and immediately after (ED) dialysis treatment (n = 36). In a subgroup (n = 10), messenger RNA (mRNA) expression was determined hourly during a 5 h HD. Results. The expression of GPx-1, GPx-4, GSSG-R, GSH-S, SOD-1 and CAT mRNA was not affected by a single HD treatment. All mRNAs were significantly (P < 0.05) increased in HD patients [median (16. percentiles (perc.); 84. perc.)]: GPx-1: 2.18 (0.89; 3.23); GPx-4: 0.41 (0.26; 0.74); GSSG-R: 0.04 (0.02; 0.10); GSH-S: 0.04 (0.02; 0.08); SOD-1: 0.32 (0.20; 0.62); CAT: 0.12 (0.06; 0.18) when compared with healthy blood donors (GPx-1: 0.91 (0.60; 1.44); GPx-4: 0.27 (0.16; 0.43); GSSG-R: 0.02 (0.01; 0.02); GSH-S: 0.02 (0.02; 0.04); SOD-1: 0.15 (0.10; 0.18); CAT: 0.07 (0.04; 0.16). Conclusions. These results show that the HD procedure does not acutely affect the antioxidant defence system on the gene level but suggest that the chronic stress caused by uraemia and/or HD may cause gene induction of the enzymatic defence system.
