Supplementary Fig.1Effects of A. cinnamomea extract on anti-oxidative gene expressions. MRC-5 cells were incubated without or with A. cinnamomea (A.C.) extract for 24 h. Quantitative real-time RT-PCR was performed to examine the relative SOD1 mRNA expression levels. Values were normalized to β-actin and are expressed relative to the respective control group. ∗p < 0.05.
