ABSTRACT The transcription factors MECOM, PAX8, SOX17 and WT1 are candidate master regulators of high-grade serous ‘ovarian’ cancer (HGSC), yet their cooperative role in the hypothesized tissue origin, fallopian tube secretory epithelium (FTSEC) is unknown. We generated 26 epigenome (CUT&TAG, CUT&RUN, ATAC-seq HiC) data sets 24 profiles RNA-seq factor knock-down followed by RNA sequencing FTSEC HGSC models to define binding sites gene regulated these cis trans . This revealed that lineage-enriched, super-enhancer associated whose DNA-binding patterns target genes re-wired during tumor development. All four TFs were indispensable for clonogenicity survival but only depletion PAX8 impaired cell survival. These pharmacologically inhibited transcriptional inhibitors HGSCs not FTSECs. Collectively, our highlights tumor-specific epigenetic remodeling tightly related activity targetable a manner through inhibitors.

Significant racial disparities exist between Black and White patients with uterine serous carcinoma (USC). While the reasons for these are unclear, several studies have demonstrated significantly different rates of driver mutations groups, including TP53. However, limited research has investigated transcriptional differences tumors or composition tumor microenvironment (TME) groups. Here, we report single-nuclei RNA-sequencing profiles primary USC from diverse backgrounds. We find that there significant patients.
