Inhibition of estrogen signaling and induction of cell death after TGFB1 treatment in MCF7 cells. Time trends in the expression of genes related to estrogen signaling and apoptosis in MCF10A and MCF7 cells: (a) steroid receptors and EGFR; (c) ESR1 targets; (d) prosurvival genes; (e) proapoptotic genes. The cells were treated according to the scheme shown in Figure S2a. TGF, direct TGFB1 treatment; CM, conditioned medium treatment. *** padj < 0.0001, ** padj < 0.001, * padj < 0.05 (significance of differences was marked for the entire run if the adjusted p value vs. Ctr reached a given value at least at one experimental point). (b) Response of MCF7 and MCF10A cells to TGFB1 treatment analyzed by Western blot. The cells were treated according to the scheme shown in Figure S2a. The levels of the indicated proteins were analyzed in total protein extracts. ACTB was used as a loading control
