Fig. 1: SUMOylation inhibition potentiates Dex-induced cell cycle arrest.

A Cell proliferation as assessed by MTS assays. Bars represent mean of 5 replicates with SD. Asterisks denote statistical significance calculated with Two-way ANOVA with Bonferroni post hoc test: *ā=āpā<ā0.05, **ā=āpā<ā0.01, ***ā=āpā<ā0.001. B Immunoblotting of SUMO2/3 or (C) GR and loading control (GAPDH) in NALM6 cells exposed to vehicle control (DMSO-EtOH), 10ānM Dex, 125ānM SUMOi or combination as depicted by + and ā signs. Average SUMO2/3 or GR signal from two replicates normalized to GAPDH and further to time point vehicle control is indicated below the samples. D Bar graph of flow cytometric cell cycle analysis. Bars represent mean of 3 replicates with SD. Asterisks denote statistical significance calculated with One-way ANOVA with Bonferroni post hoc test: *ā=āpā<ā0.05, **ā=āpā<ā0.01, ***ā=āpā<ā0.001. E Representative flow cytometry gating strategy for the cell cycle analysis. F, G Bar graphs of flow cytometric apoptosis analysis for cells in early-stage and late-stage apoptosis stages, respectively. Bars represent mean of 3 replicates with SD. Asterisks denote statistical significance calculated with One-way ANOVA with Bonferroni post hoc test: *ā=āpā<ā0.05, **ā=āpā<ā0.01, ***ā=āpā<ā0.001.
