Elevated phosphaturia generates renal oxidative stress. Glutathione peroxidase (GPx) activity in renal tissue. (A) GPx activity was determined in 20 µg of total protein extracts of kidney samples by a coupled reaction with glutathione reductase. Units are expressed as nanomoles of NADPH oxidized per minute and milliliter. White bars are LPD (0.2%P diet) groups and black bars are HPD (1.2%P diet) groups. t-test analysis *p < 0.05, **p < 0.01. (B) Negative correlation between renal mRNA α-klotho expression and GPx activity.
