In the present study, the role of Mus81 in gastric cancer was explored. Materials and Methods: Mus81 expression in 53 cases of gastric cancer and the corresponding normal tissues was determined by quantitative real-time PCR. The correlations between Mus81 down-regulation and the clinicopathological data were also evaluated. Results: Mus81 expression was significantly lower in gastric cancer tissues than the corresponding normal tissues (p=0.018) and the down-regulation of Mus81 occurred in 51% (27/53) of the gastric carcinomas. More importantly, Mus81 down-regulation correlated significantly to invasion depth (p=0.015) and poorly-differentiated type (p=0.016) of gastric cancer. Conclusion: Mus81 might be a potential marker for the malignancy of gastric cancer.
