Kidney tissues were homogenized using radio-immunoprecipitation assay buffer (Wako Pure Chemicals, Osaka, Japan). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blotting were performed as described previously [24 (link)]. The primary antibodies against 5α-Red1 (Abcam, Cambridge, UK), 11β-HSD2 (Proteintech, Rosemont, USA), and β-actin (Abcam, located in Cambridge, UK) were used. The immunoreactive bands were visualized using Immobilon Western Chemiluminescent HRP Substrate (Millipore, Billerica, MA, USA). The intensities of the specific chemiluminescent bands were analyzed using an ImageQuant LAS 3000 (GE Healthcare, Amersham, UK).
