摘要
目的研究乳腺癌组织和细胞株中Mage基因的表达情况。方法采用RTPCR检测33例乳腺癌组织和4株乳腺癌细胞株MCF7、SkBr3、MDAMB435s和TM40D中Mage基因的表达。结果33例乳腺癌组织中13例(39%)至少表达一种MageA基因,4例(12%)MageA1阳性,8例(24%)MageA2阳性,7例(21%)MageA3阳性,细胞株MCF7中MageA1和MageA3阳性表达,SkBr3中MageA1和MageA3阳性表达,MDAMB435s中MageA2和MageA3阳性表达,TM40D中MageA3阳性表达。结论Mage基因在乳腺癌中表达率较高,不同的乳腺癌细胞表达Mage基因有差别,Mage蛋白可望成为乳腺癌免疫治疗的靶抗原。
Objective To study the expression of Mage A1、A2、A3 in breast cancer tissues and four breast cancer cell lines Methods The expression of Mage A1、A2、A3 in breast cancer tissues and four breast cancer cell lines, MCF 7、Sk Br 3、MDA MB 435s and TM40D was detected by reverse transcription polymerase chain reaction (RT PCR) Results The positive expression rate of Mage A in breast cancer tissues was 13/33 (39%), of Mage A1 was 4/33 (12%), of Mage A2 was 8/33 (24%), and of Mage A3 was 7/33 (21%), respectively Both Mage A1 and Mage A3 were positive in breast cancer cell line MCF 7 and Sk Br 3 MDA MB 435s expressed Mage A2 and Mage A3 Mage A3 was positive in TM40D Conclusion Mage genes were often expressed in breast cancer, but expression of Mages varies in the breast cancer cell lines Mage genes encoding proteins are eligible for Mage peptide based active immunotherapy
