TFAP2A overexpression in NMuMG modulates epithelial plasticity. a Expression of either GFP or TFAP2A was induced by 72 h doxycycline treatment in NMuMG cells stably transduced with either pCLX-GFP or pCLX-TFAP2A. Morphological changes and sparse cell arrangement are visible in phase contrast microscopy upon TFAP2A expression. Scale bar: 50 μm. b Gene expression log2 fold changes of EMT markers (TFs) were calculated from mRNA-seq samples of doxycycline-induced, TGFβ1-treated (72 h, 2 ng/mL) pCLX-GFP (pCLX-GFP + TGF-beta), doxycycline-induced pCLX-TFAP2A (pCLX-TFAP2A), as well as of doxycycline-induced, TGFβ1-treated (72 h, 2 ng/mL) pCLX-TFAP2A (pCLX-TFAP2A + TGF-beta) cell lines relative to doxycycline-induced pCLX-GFP (pCLX-GFP) cell line. Shown are the mean log2 fold changes (+/- 1 standard deviation) from two experiments. TFAP2A overexpression is apparent in both TFAP2A-induced samples (dark green and dark blue) but is not induced in cells treated with TGFβ1 alone (light blue). The EMT-inducing TFs have increased expression upon TFAP2A induction. * indicates a p-value ≤ 0.05 and ** a p-value ≤ 0.01 in a two-tailed t-test. c The transcriptional activities of TFAP2{A,C} and SNAI1..3 motifs in different conditions, as inferred with ISMARA from mRNA-seq data as described in (b). The two replicates from each condition are plotted next to each other
