a Patient characteristics. Histogram of LVEFs for the patients under study (n = 15). Chronic cardiotoxic patients (dark blue) and control cardiomyopathy patients (light blue) are sorted after LVEF. b LVEF (X-axis) of chronic cardiotoxic patients decreases with duration of chemotherapy in days (Y-axis); color of the nodes correspond to LVEF classification of the respective patient. c Examples of in vitro-derived ACT response proteins whose expression in biopsies of cardiotoxic patients correlate with LVEF. X-axes shows LVEF, Y-axis shows normalized protein expression. Color of the nodes correspond to LVEF status similar to b. d Discordant correlation values of biopsies protein expression with the LVEFs of the two patient groups. Blue bars: correlation with respect to cardiotoxic patients, red bars: control group. X-axis: genes, Y-axis: correlation values (range [−1,1]). e Pairwise comparison of protein expression fold-changes of measured time points (8, 24, 72, 168, 240, and 336 h) against the earliest time point (2 h) in 3D cardiac microtissues using Student’s t-test on n = 3 experimental replicates. Y-axis: bars indicate log2-fold change. Colors of the bars indicate significance of fold-change (dark blue: Q < 0.05; light blue: Q ≥ 0.05).
