YAP1 knockdown depleted FUS‐DDIT3‐expressing MLS 402‐91 and MLS 1765‐92 cells to a similar extent as knockdown of KIF11, an essential cell cycle regulator that served as positive control, whereas there was little effect in cell lines representing other liposarcoma subtypes (Fig 3A and B, Appendix Fig S3A and B). This evidence concerns the gene DDIT3 and liposarcoma.
