The effect of NMN on free radicals and related inflammatory factors. (A) The effect of NMN on free radicals induced by H₂O₂. (B) The effect of NMN on antioxidant enzymes CAT induced by H₂O₂. (C) The effect of NMN on antioxidant enzymes SOD induced by H₂O₂. (D–I) Detection of mRNA expression levels of TNF-α, IL-1β, ICAM1, MMP-9, eNOs, and NF-κB p65 using reverse transcription method. The results represent the average of three parallel experiments. Statistical analysis was conducted using the t-test, with the BC groups as the reference. Significance levels are expressed as: p-value < 0.05 as *, p-value < 0.01 as **.
