In Fig 4C, significantly elevated MAGE-A3 and MAGE-A4 RNA transcript levels were also detected by qPCR in primary Pam 212 cSCC tumors compared to normal murine keratinocytes and Pam 212 cells in culture (77.4± 46.2 vs. 1± 0.1 vs. 2.62± 2.1; 90.4± 68.3 vs. 1± 0.1 vs. 1.86± 1.19, respectively; all p < 0.05). The gene discussed is MAGEA3; the disease is skin squamous cell carcinoma.
