LCN2 and Glomerular sclerosis: According to the IHC results, the areas positively stained for Neutrophil gelatinase‐associated lipocalin (NGAL), TRPC5, and 8‐OHdG (an oxidative DNA damage marker) in regions with glomerular sclerosis were decreased after GQDs administration compared with that observed in the AD‐injected group (Figure 3A).
