摘要 目的探讨同源异型盒基因EN-2在不同前列腺癌细胞及人正常前列腺上皮细胞中的表达差异及意义。方法采用逆转录-聚合酶链反应(RT—PCR)和免疫荧光法检测前列腺癌PC3、DUl45和LNCAP细胞以及人正常前列腺上皮细胞RWPE-1中EN2mRNA和蛋白的表达,采用酶联免疫吸附试验(ELISA)法检测上述细胞培养液中EN2蛋白的含量变化。结果RT—PCR和ELISA检测结果显示:EN2mRNA和蛋白水平在激素依赖性前列腺癌细胞LNCAP(1.65±0.19、8.74±0.34)和激素非依赖性前列腺癌细胞PC3中(1.08±0.12、3.07±0.24)及DU145(1.15±0.53、2.86±0.26)均高于人正常前列腺上皮细胞(0.42±0.11、0.86±0.99)(P〈0.05),其中LNCAP细胞中EN2mRNA和蛋白表达水平高于其余两种前列腺癌细胞(P〈0.05)。结论EN2在前列腺上皮细胞中呈低表达,在各前列腺癌细胞株中表达增高,并为前列腺癌细胞所分泌。EN2的表达可能与前列腺癌发生发展有关。 Objective To investigate the expression of Engrail-2 (EN2) and its significance in different prostate cancer cell lines and normal human prostate epithelial cell line. Methods The expression of EN2 was detected in prostate cancer cell lines (PC3, DU145, LNCAP) and normal prostate epithelial cell line RWPE-1 by using reverse transcription-polymerase chain reaction (RT-PCR), enzyme linked im- munosorbent assay (ELISA) and immunofluorescence. Results The EN2 mRNA and protein expression levels in Pca cell lines ( LNCAP, PC3, DU145 ) were 1.65 ±0. 19/8.74± 0. 34, 1.08 ± 0. 12/3.07 ± 0. 24, and 1.15 ±0. 53/2. 86 ±0. 26 respectively, which was significantly higher than in normal prostate epithelial cell line RWPE-1 (0. 42± 0. 11/0. 86 ± 0. 99 ) ( P 〈 0. 05 ). The EN2 level was higher in LN- CAP cells than in PC3 and DU145 cells ( P 〈 0. 05 ). Conclusion The expression of EN2 in 3 prostate cancer cell lines is higher than in RWPE-1 and EN2 protein can be secreted by prostate cancer cells. It is important for the further study on the EN2 potential roles in the occurrence and development of prostate carcinoma.
