Figure Lengend Snippet: Hypoxia increases expression of EZH2, H3K27me3 and survivin. (A) Immunoblots of WCEs from U2OS, HeLa and MRC5 lines cultured under normoxic or hypoxic environments (24 h). Blots were immunoprobed with anti-EZH2, anti-H3K27me3 and anti-survivin antibodies. Anti-Hif1a used to prove the hypoxic state had been induced, and anti-tubulin was used as a loading control. (B–D) Quantification of immunoblots represented in A from three independent experiments demonstrating that EZH2, H3K27me3 and survivin are all more abundant under hypoxia. Data presented are means±s.d. * P <0.05, ** P <0.01, *** P <0.001 (two-way ANOVA with Tukey's multiple comparisons post test).
