  Fig. 1. FUS-DDIT3 peaks annotation in ML017 controls. A Genomic distribution (%) of the annotated peaks from the consensus of the control (CTRL) condition in ML017. Color regions as reported in the legend. B Enrichment map obtained from the annotated genes of the consensus CTRL of ML017. Pathways are reported as circles, they are connected when sharing at least 50% of the genes. The node size is proportional to the number of genes in the pathway. The node fill color is proportional to the fraction of the significant genes over the total number of genes in the pathway (see Materials and Methods)

Color regions as reported in the legend. B Read enrichment analysis around DBPs in CTRL and ET-72h conditions in ML017. C MAplot of log concentration versus log Fold Change of the identified DBPs. D Enrichment map of the annotated genes associated with pathways. Pathways are reported as circles, they are connected when sharing at least 50% of the genes. The node size is proportional to the number of genes in the pathway. The node fill color is proportional to the fraction of the significant genes over the total number of genes in the pathway (see Materials and Methods)

  Fig. 4. Comparison between ChIP-Seq and RNA-Seq data in ML017ET. A Figure shows the number (N) of differentially expressed genes (DEGs, in green), differentially bound peaks (DBPs, in pink), and unique genes associated with DBPs (in magenta), under the three trabectedin-treated conditions (ET-24h, ET-72h, ET-15d) in ML017ET model. B Venn diagram comparing the unique genes related to DBPs at ET-24 and the DEGs under the same condition

  Fig. 5. Mechanism of action of trabectedin in myxoid liposarcoma. A Venn diagrams showing the common genes between DEGs, divided in up- and down-regulated, and the unique genes annotated to DBPs, in ET-72h and ET-15d, respectively, in the ML017 model. B Enrichment map showing the common pathways between RNA-Seq and ChIP-Seq analysis at ET-15d in ML017. Common pathways are reported as black circles. Common genes are connected by an edge to the pathway they belong to, and the color shows their transcriptional regulation: red for up-regulated genes, blue for down-regulated genes. The darker the color the greater the regulation. D Schematic overview of the possible mechanism of action of trabectedin in myxoid liposarcoma guided by ChIP-Seq and RNA-Seq results
