Positivity in BKZ-2 and BKZ-3 cells for the 40 kDa single transmembrane protein EPCAM encoded by tumor-associated calcium signal transducer-1 gene [55] was relevant as epithelial adhesion molecule playing a role in carcinogenesis of epithelial cells by activating expression of proto-oncogenes MYC and CYCLIN A/E [56]. Here, EPCAM is linked to neoplasm.
