Figure Lengend Snippet: Inhibition of p300’s enzymatic activity hinders cell proliferation and GR transcriptional regulation. ( A ) Depiction of chemical structures of coregulator inhibitors. A-485, p300/CBP histone acetyl transferase (HAT) domain inhibitor; CCS1477, p300/CBP bromodomain inhibitor; I-BET762, bromodomain and extra terminal domain (BET) bromodomain inhibitor; BRM014, BRM/BRG1 ATP domain inhibitor. (B–E) Bar graphs depict KLK3 gene expression analysis in VCaP ENZ 0 ( B ), VCaP ENZ 3w ( C ), 22Rv1 ENZ 0 ( D ), and 22Rv1 ENZ 3w ( E ) cells treated with or without Dex in the presence or absence of 0.1 or 1 μM of indicated inhibitor. Bars represent mean ± SD, n = 3. Statistical significance calculated using one-way ANOVA with Bonferroni post hoc test. (F, G) Line graphs depict change in cell proliferation as function of time in VCaP ( F ) and 22Rv1 ( G ) ENZ 0 and ENZ 3w cells with or without indicated chemical inhibitor treatment. Each data point represents mean ± SD, n = 3. Statistical significance calculated using Two-way ANOVA with Bonferroni post hoc test. * P < 0.05; ** P < 0.01; *** P < 0.001.
Article Snippet: For experiments with the coregulator inhibitors, the cells were treated with 0.1 μM or 1 μM A-485 p300/CBP HAT (Tocris, #6387), CCS1477 p300/CBP bromodomain (MedChemExpress, #HY-111784), I-BET762 BET bromodomain (Sigma, #SML1272), or BRM014 BRM/BRG1 ATP (MedChemExpress, #HY-119374) inhibitors.
