Hyperoxia downregulates catalase expression in the proximal tubules and collecting ducts. (a) Catalase expression in the proximal tubules and collecting ducts of newborn rats exposed to normoxia or hyperoxia was detected by immunohistochemical staining (original magnification ×400; scale bar, 100 μm). (b) The immunostaining intensity of catalase expression in the proximal tubules exposed to normoxia or hyperoxia is shown by box and whisker plots. Relative expression is standardized to the value of the normoxia group on P1D. The whiskers represent the minimal intensity or the maximal intensity, and the boxes span the interquartile range of measurements for 10 rats with the mean value of 10 separate fields of view (n = 10). ∗P < 0.05, one-way ANOVA, Bonferroni post hoc test. (c) The immunostaining intensity of catalase expression in the collecting ducts exposed to normoxia or hyperoxia is shown by box and whisker plots. Relative expression is standardized to the value of normoxia group on P1D. The whiskers represent the minimal intensity or the maximal intensity, and the boxes span the interquartile range of measurements for 10 rats with the mean value of 10 separate fields of view (n = 10). ∗P < 0.01, one-way ANOVA, Bonferroni post hoc test.
