ABSTRACT
Genes of cancer-associated testis antigens (CTAs) are expressed in various cancer tissues. In order to use CTAs as cancer diagnosis marker, we developed molecular method for detection of CTAs transcripts in tissue. In order to know the applicability of DNA of cancer-associated testis antigens (CTAs) on cancer diagnosis, molecular diagnostic methods for detection of gene expression of melanoma antigen gene (MAGE), GAGE, and B melanoma antigen (BAGE) was studied. After comparing DNA sequences of CTAs, S1/AS1 and S2/AS2, GAGE-S/ GAGE-AS, and BAGE-S/BAGE-AS primers were designed for the detection of MAGEs, GAGEs and BAGEs, respectively. The gene expression of CTAs in cancer cell lines, head and neck cancer tissues, ovary cancer tissue, and peritoneal cells of gastric cancer patients were investigated by reverse transcription-polymerase chain reaction (RT-PCR) using these primers. The MAGEs, GAGEs and BAGE genes were expressed in 8/8 (100%), 5/8 (62.5%) and 1/8 (12.5%) of head and neck cancer tissues, respectively. The gene expression of MAGEs were also detected in 8/10 (80%) of ovary cancer tissues and in 9/10 (90%) of peritoneal cells of gastric cancer patients in RT-PCR test using S1/AS1 primers. The results of this study suggest that molecular diagnosis method using CTAs genes, especially RT-PCR using S1/AS1 primer combination, is useful for diagnosis of cancer and it will be used for the prediction of cancer progression or regression and metastasis in future.
