Figure 7: Protein expression level of IL-1β, IL-6 and TNF-α in the retina of mice at the age of 17 days. (A) Western blot bands of IL-1β, IL-6 and TNF-α. (B) Quantification of IL-1β, IL-6 and TNF-α protein. Data are expressed as the mean ± SD (n = 15 mice per group). **P < 0.01 (Mann-Whitney U test). IL: Interleukin; OIR-C: oxygen-induced retinopathy, control eye; OIR-T: oxygen induced retinopathy eye injected intravitreally with MEG3 overexpression lentivirus; TNF: tumor necrosis factor.
