Abstract:
Objective To study the expression of GPC3 mRNA and GPC3 protein in ovarian carcinoma, and to investigate the clinical significance of their expression. Methods 35 specimens of ovarian carcinomas and 23 specimens of normal ovarian tissues were obtained from the patients undergoing operation during Jan. 2004 to Oct. 2005. The expressions of GPC3 mRNA in ovarian carcinomas and normal ovarian tissues were detected by real-time fluorescence quantitative PCR (RT-PCR). The clinical and pathological characteristics of ovarian carcinomas were analyzed. The expression of GPC3 protein was detected in 4 specimens of ovarian carcinomas and 3 specimens of normal ovarian tissues by Western bloting. Results The expression level of GPC3 mRNA in ovarian carcinomatous was down-regulated compared with that in normal ovarian tissues (P0.05). The expression of GPC3 protein was consistent with the expression of GPC3 mRNA. GPC3 protein was doubly or trebly expressed in normal ovarian tissues compared with ovarian carcinomas. Conclusion The present study suggests that GPC3 may be related to the occurrence and development of the ovarian carcinoma. The simultaneous determination of GPC3 and CA125 may increase the sensitivity of diagnosis for ovarian carcinoma.
