We focused on ZEB2 (Zinc finger E-box binding homeobox 2), a well-known player in epithelial to mesenchymal transition process, and we showed that ZEB2 is exclusively expressed in immune cells in single-cell transcriptome and, at the same time, downregulated in TCGA-UCEC (The Cancer Genome Atlas—Uterine Corpus Endometrial Carcinoma) bulk RNA-seq data and negatively associated with tumor purity. The gene discussed is ZEB2; the disease is neoplasm.
