Epithelial characteristics of ovarian clear cell carcinoma at single-cell resolution.

ABSTRACT: Ovarian clear cell carcinoma (OCCC) represents a rare and aggressive subtype of epithelial ovarian cancer with distinctive clinical and molecular characteristics. However, the identification, origin, and molecular features of the malignant epithelial cells in OCCC remain poorly studied. We establish an OCCC-associated transcriptional landscape using single-cell RNA sequencing and investigated the properties of epithelial cells in tissues from normal ovaries, ovarian endometriosis, primary OCCC and recurrent OCCC to assess the status of malignant epithelial cells. We identify a specific subcluster of malignant epithelial cells and further analyze them to discover 173 candidate factors associated with OCCC. Regulon and pseudotime trajectory analyses reveal six transcription factors (TFs) and
