Expression Profiling of Inflammatory Breast Cancer Cells Treated with the Novel Histone Deacetylase Inhibitor, CG-1521 (Agilent miRNA v12.0). Homo sapiens

Studies of gene expression profiles using the whole genomewide microarray analysis of miRNA in SUM149PT cells (ER-, p53mut) and SUM190PT cells (ER-, p53mut) when treated with 5-7.5 µM CG-1521 alone and in combination with 10 nM 17β-Estradiol. Comparisons between each treatment group provides evidence for the dysregulation of miRNA affecting genes associated with the spindle assembly checkpoint. Overall design: Four independent experiments were carried out in SUM149PT and SUM190PT cells, which were treated with vehicle (ethanol/DMSO), 10nM 17β-Estradiol, 5 or 7.5µM CG-1521, and the combination of 17β-Estradiol and CG-1521. Total RNA was extracted from cell lysates using QIAGEN miRNeasy mini kit after 48h of treatment.
