Ovarian cancer is a leading cause of cancer-related women mortality in China. In recent years, the molecular mechanisms involved in ovarian carcinoma development and/or progression have been intensely studied, and several genes have been identified. Deleted in Colorectal Carcinoma (DCC), is an important tumor suppressor gene, which is inactivated in many kinds of tumors, and its function(s) is not clarified. Even though the lost expression of DCC occurred in later stages of multistep colorectal carcinogenesis, its contribution to the onset or progression of ovarian cancer is not fully understood. To investigate DCC expression in ovarian cancer, we studied 254 clinical samples by RT-PCR. Our results revealed that 52% malignant ovarian cancer did not express DCC gene. By contrast, DCC expression was observed in all normal ovary tissues and 80% benign ovarian tumors. Obviously, there was a significant correlation between DCC expression and ovarian cancer, especially in the epithelial ovarian cancer. The present study also suggested that the loss expression of DCC occurred more frequently in the cases of later clinical stage, higher pathological grade, and poorer prognosis. In the other part of this study, we further explored DCC expression after transfection in two kinds of ovarian cancer cell lines, namely SKOV3 cell and HO-8910 cell, using RT-PCR and immunocytochemistry. The results indicated that DCC expressed in SKOV3-DCC and HO-8910-DCC cells, and ultrastructural analysis showed the appearance of apoptotic features in them. Furthermore, cell growth was markedly down-regulated in above groups of cells, indicating that transfection with the DCC constructs can suppress the growth of tumor cells. In conclusion, our results suggest an association of lost expression of DCC with the ovarian cancer, and DCC gene may inhibit the growth of ovarian carcinoma cells. However, this result needs further trials with a larger sample.
