Figure 3From: MYC regulates the unfolded protein response and glucose and glutamine uptake in endocrine resistant breast cancerCombination of MYC inhibitor and antiestrogen increased G1 cell cycle arrest in endocrine resistant cells. A, Top, ICI (100 nM), 10058-F4 (25 μM), or the combination significantly increased percentage of cells in G1 arrest and reduced percentage of cells in S phase in LCC1 (p < 0.001). Bottom, Representative cell count plots for propidium iodide (PI) in LCC1 cells are shown. B , Top, Only the combination of ICI and 10058-F4 induced significant increase in G1 arrest in LCC9 cells (p < 0.001). Bottom, Representative cell count plots for PI in LCC9 cells are shown. Graphs represent data that are presented as the mean ± SE for three independent experiments. ANOVA, p < 0.001; *p < 0.001 for indicated treatment versus vehicle control.Back to article page
