Gene expression change after LSD1 siRNA treatment in ER-negative breast cancer cells MDA-MB-231

ABSTRACT: Knock-down of LSD1 using siRNA approach induced regulation of several proliferation-associated genes in ER-negative breast cancer cells MDA-MB-231. To identify changes on gene expression caused by treatment with siRNA directed against LSD1 (si) or control siRNA (control) in MDA-MB-231 cells, total RNA was purified from the cells after treatment for 6 days (2 rounds of transfection). Three biological replicates were used.

Histone modifying enzymes confer epigenetic marks, directing the changes in gene expression required for diverse cellular processes. Lysine-specific demethylase 1 (LSD1) functions as a transcriptional coregulator by demethylating histone H3 on lysine 4 and lysine 9. Analyzing transcriptomes on microarrays, we identified genes which represent inflammatory-related targets of LSD1. We demonstrate a repressive role of LSD1 in proinflammatory cytokine expression such as IL1α, IL1β, IL6 and IL8 and cl  ...[more]
