Differential expression profile of MAGE family in non-small-cell lung cancer.
The expression of the melanoma-associated antigen (MAGE) genes consists of variables in all tumor types, such as lung cancer, which are relevant to be silent in all normal tissues except germ cells. They are considered as tumor-specific antigens, and are ideal targets for cancer immunotherapy. A complete MAGE genes differential expression profile analysis of lung cancer can provide this study not only various target genes for immunotherapy, but also valuable markers for further diagnosis and prognosis. This research has constructed a membrane array, which was consisted 32 MAGE genes, to detect whether the differential expression profile occurred in 52 pairs of non-small-cell lung cancer (NSCLC) samples. Nearly 32 MAGE genes have been differential expressed in NSCLC except MAGE-B1 and -E2. MAGE-B, -C, -D, and subgroup -B6, -D4 have showed prominences in lung adenocarcinoma. High-frequent expression of MAGE-D, and subgroup -A2, -D2 has also been discovered in non-metastasis group (p<0.05). However, there is no significant difference of MAGE genes differential expression shown among different primary tumor (T), nodal involvement (N) and overall stages. Several MAGE subgroup genes, such as MAGE-A5, -A7, -A8, -A9, -A11, -B3, -B4, -B10, -D2, -D3, -F1, -G1, -H1, and -L2, have been first discovered to show differential expression in NSCLC. Although the small size of the sample may limit the diagnostic and prognostic value of MAGE genes, the function of the membrane array can provide this study a high-throughput method to detect the whole MAGE genes differential expression profile.
