Background:
The aim of this study is to detect the expression of melanoma antigen-C2 (MAGE-C2) in lung adenocarcinoma tissues and adjacent non-cancerousous tissues and analyze its clinical significance.
Methods:
The expression level of MAGE-C2 mRNA and MAGE-C2 protein were measured in 87 cases of lung adenocarcinoma tissues and adjacent non-cancerous tissues were detected by Real-time fluorescence quantitative PCR and Western blot.
Results:
Over-expression of the MAGE-C2 mRNA and MAGE-C2 protein were observed in lung adenocarcinoma tissues (53/87, 60.9%), but nor in adjacent non-cancerous tissues. The expressions of MAGE-C2 mRNA and MAGE-C2 protein were closely associated with clinical stage, metastasis and differentiation (P<0.05). The expression rate of MAGE-C2 mRNA had no relationship with gender, age, smoking (P>0.05). The expression of MAGE-C2 had an adverse effect on overall survival rate (P<0.05).
Conclusions:
Over-expression of the MAGE-C2 mRNA and protein is existed in lung adenocarcinoma. The high expression of MAGE-C2 may be closely related to the occurrence and development in lung adenocarcinoma. MAGE-C2 may predict a poor prognosis and could be as a novel lung adenocarcinoma molecule marker. .
