For instance, in many carcinomas—BRCA, ESCA, and non-small cell lung carcinoma (NSCLC)—the EMT status of cells strongly associates with PD-L1 expression levels [56], at least partly through the action of pathways such as phosphoinositide 3-kinase/protein kinase B pathway [57]. Here, CD274 is linked to non-small cell lung carcinoma.
