S100A6 and acute kidney injury: The overexpression of S100A6 clearly attenuated I/R and cisplatin‐triggered AKI, as evidenced by decreased BUN and Cr levels (Figures S11A–C and S12A,B), along with reduced RTD (Figures S11D,G and S12C,F) and diminished renal tubular cell apoptosis (Figures S11E,H and S12D,G).
