Figure 3 PQQ inhibits high glucose-induced OS damage in NRK-52E cells. (A) CCK-8 method for detecting optimal culture concentration and time of PQQ. (B) Western blot detects SOD1 and SOD2 expression. (C) Protein analysis. (D) SOD1 mRNA. (E) SOD2 mRNA. (F) CAT activity. (G) GSH-Px content. * Compared with the control group, P<0.05; # Compared with the high glucose group, P<0.05. PQQ – pyrroloquinoline quinone; OS – oxidative stress; CCK-8 – Cell Counting Kit-8; SOD – superoxide dismutase; mRNA – messenger RNA; CAT – catalase; GSH-Px – glutathione peroxidase.
