Cytotoxicity of H₂O₂ and protective effects of LFP-a1 in H₂O₂-challenged L02 cells. (a) Effect of H₂O₂ on cell viability of L02 cells, respectively. (b) Effect of LFP-a1 on cell viability of L02 cells against H₂O₂-insult. (c) Effect of LFP-a1 on cell proliferation of L02 cells against H₂O₂-insult. (d) Edu and Hoechst 33342 fluorescent staining of L02 cells (EdU: staining in red; Hoechst 33342: staining in blue, original magnification: ×200). Data are expressed as the mean ± SD (n = 3) and are representative of at least three independent experiments (^∗p < 0.05, ^∗∗p < 0.01, ^∗∗∗p < 0.001 compared with control cells, ^#p < 0.05, ^##p < 0.01 compared with H₂O₂-challenged cells).
