Fig. 7From: Complement C3 deficiency alleviates alkylation-induced retinal degeneration in miceOxidative stress level in MMS-treated mouse retina. a–d Nrf2, Nqo1, Hmox-1 and Sod2 mRNA levels in mouse retinal tissue were measured by real-time qPCR before and 1, 3, and 7 days after MMS injection and are expressed as the fold change compared with that in the control group after normalization to mβ-actin level (n = 6, ***P < 0.001 compared with control). MMS, methyl methane sulfonate; WT, wild-typeBack to article page
