Figure Lengend Snippet: Fig. 2 Effects of oxidative stress on glycolysis pathway. A Schematic diagram illustrating the preparation of supernatant from SV-ECs following short-term stimulation of 500 μM H2O2 for 2 h. B Heat Map showing the differential expression analysis of SV-ECs treated with or without 500 μM H2O2. C–F SV-ECs were cultured in CCM with short-term stimulation of 500 μM H2O2 for 2 h and subsequently in SFM without H2O2 for another 24 h (C, D), or in SFM with long-term stimulation of 500 μM H2O2 for 48 h (E, F). Relative mRNA levels of glycolysis-related genes were analyzed by qRT-PCR (D, F). G, H Western blot analysis of the glycolysis-related genes in SV-ECs treated with H2O2 for 2, 24 and 48 h (n = 3). The data is expressed as Mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001 analyzed by one-way ANOVA.
