Expression profiling of oxidative stress components by semiquantitative RT-PCR. GCS, γ-glutamylcysteine synthetase; GSHPx, glutathione peroxidase; GSSG-R, glutathione reductase; SOD 1, Cu/Zn superoxide dismutase; SOD 2, mitochondrial superoxide dismutase. The constitutive expression of rhoA is shown as loading control.
