CTAG2 and plasma cell myeloma: We also detected the expression of other CTA genes, namely, NY-ESO-1, MAGE-A1, MAGE-A2, MAGE-C1, LAGE-1, and PRAME. MAGE-A1 and MAGE-A3 were found to be commonly expressed in five myeloma cell lines (KMM1, KMS20, KMS21, KMS26, and KMS27), while NY-ESO-1 was detected in six cell lines (KMM1, KMS20, KMS21, KMS26, KMS27, and MUM24), and MAGE-A2 and MAGE-C1 were detected in seven cell lines (KMM1, KMS21, KMS26, KMS27, KMS20, and MUM24).
