Across the six abovementioned carcinomas, except occasional deviations seen in PAAD, CD274 expression levels correlated positively with a mesenchymal and a partial EMT signature but correlated negatively with both the hallmark OXPHOS pathway and epithelial signatures (Figure 3A, left), consistent with the meta-analysis presented earlier (Figure 1 and Figure 2). The gene discussed is CD274; the disease is carcinoma.
