Additional file 2: Figure S2. CDH1 and EpCAM are targeted by ZEB2 and SIRT1 modulating H3K9Ac level. (a) HA-ZEB2 ChIP assay after induction (+dox) analyzed on CDH1 and EpCAM promoter location using published sequences. (b) H3K9Ac ChIP assay performed in MDA-MB-231, 48 h after ZEB2 siRNA treatment (siZEB2). (c) RAB25 mRNA expression measured by qRT-PCR in HT29, MCF7, BT549 and MDA-MB-231. P values were determined using two-way ANOVA (***p < 0.001). (d) SIRT1 ChIP and (e) H3K9Ac ChIP assay performed after ZEB2 induction (+dox) with SIRT1 inhibitor (EX-527, 1 μM) (+dox/EX-527), in MCF7 analyzed on CDH1 and EpCAM promoter. Enrichments to input were calculated, control values were set as 1 and s.d. is shown. For all analyses, p values were determined using two-way ANOVA (*p < 0.05; **p < 0.01). NC = negative control. Three independent experiments were performed for all experiments.
