title: Different expression of MAGE-A-antigens in foetal and adult keratinocyte cell lines.
abstract: MAGE-A-antigens are an immunologic marker for many cancers. The goal of this study was to compare the expression profiles of MAGE-A2, -A3, -A4, -A6 and -A10 in foetal and adult keratinocytes with an oral squamous cell carcinoma (OSCC) cell line. Expression of MAGE-A2, -A3, -A4, -A6 and -A10-antigens were detected with PCR in foetal and adult keratinocyte cell lines and in an OSCC cell line (pT4N1M0). Quantitative expression of the single MAGE-A-antigens was measured with rtq-PCR. The results were compared to the reference value of the adult keratinocyte cell line. MAGE-A-antigens were detected in all cell lines. Expression profiles of adult and foetal keratinocyte cell lines differed significantly. Expression profiles of foetal and carcinoma cell lines differed significantly also. MAGE-A-antigens were detected in foetal keratinocyte cell line and oral squamous cell carcinoma cell line but differ in their expression profiles. Up to now MAGE-A-antigens were not detected in foetal keratinocytes. Their role is still unknown.
