Epithelial cell-related prognostic risk model in breast cancer based on single-cell and bulk RNA sequencing.

Objective: This study aims to construct an epithelial cell-related prognostic risk model for breast cancer (BRCA) and explore its significance.

Methods: GSE42568, GSE10780, GSE245601, and TCGA-BRCA datasets were sourced from public databases. Epithelial cell-related differentially expressed genes were identified using single-cell data analysis.
