Abstract IA27: Functional genetic architecture of serous ovarian cancer

Abstract: The degree of genetic aberrations characteristic of high-grade serous ovarian cancer (HGSC) makes identification of the molecular features that drive tumor progression difficult. Here, we perform genome-wide RNAi screens and whole-kinome proteomics to identify genes that are critical to their survival. We report that the tetraspanin CD151 contributes to survival of a subset of HGSC cell lines associated with a ZEB transcriptional program and supports the growth of HGSC tumors. Moreover, we show that high CD151… Show more

“…HGSOC cell lines appear to depend on “quality control” pathways that sense and destroy damaged transcripts and proteins. Nonsense‐mediated decay (NMD) is highly active in HGSOC cell lines . Interference with enzymes that control NMD either genetically or with small molecule inhibitors is deleterious to HGSOC cell lines.…”
