UBXN11 and carcinosarcoma: In these experiments, we tested a subset of OCI and SOC lines from mRNA/RPPA cluster 1 and cluster 2 that are representative of a spectrum of different tumour subtypes (papillary serous, clear cell, carcinosarcoma, endometrioid and mucinous), and tissue sources (solid tumours, ascites fluid and xenograft explants) (Supplementary Table 2).
