Research Article


More and more evidence has demonstrated that astrocyte elevated gene-1 (AEG-1) is tightly associated with progression, metastasis, and unfavorable prognosis in many malignancies. However, the potential biological role of AEG-1 in gastric carcinoma (GC) has not been thoroughly delineated. In the current study, we found that AEG-1 mRNA and protein levels in GC tissues were significantly higher than those in normal gastric mucosa (P < 0.05). Simultaneously, statistical analysis displayed a significant correlation of high AEG-1 mRNA and protein expressions with differentiation status, TNM staging, invasive depth, and lymph node metastasis (P < 0.05). Most importantly, expressions of AEG-1 mRNA and protein in high clinical staging and metastatic GC tissues were dramatically higher than those in low clinical staging and non-metastatic GC tissues (P < 0.05). Stepwise investigation confirmed that the survival time of the patients with high AEG-1 level was shorter than those with low AEG-1 level or negative AEG-1 staining. Taken altogether, our data presented herein suggest that AEG-1 may be a novel predictor for metastasis and prognosis of the patients with GC.
