RESUMEN
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.
RESUMEN
Objective To study the expression of human giant larvae-1 (Hugl-1) in ovarian carcinoma and its clinical significance.Methods Hugl-1 mRNA expression in 31 ovarian cancer and the corresponding adjacent tissues was examined by real time fluorescence quantitative RT-PCR and in situ hybridization.Moreover,analysis was done while taking into consideration of the clinicopathologic parameters of ovarian cancer.Results The expression of Hugl-1 mRNA in ovarian cancer tissue was significantly higher than that in the corresponding adjacent tissues ([0.051 ? 0.029]vs [0.026 ? 0.043],P
