Expression and significance of MAGE-D4 in human meningioma tissues

  • Online:2015-06-25 Published:2015-07-13

摘要:

目的 检测人脑膜瘤组织中黑色素瘤相关抗原MAGE-D4 mRNA的表达并分析其临床意义。方法 采用逆转录-聚合酶链反应(reverse transcription polymerase chain reaction,RT-PCR)方法,检测36例脑膜瘤组织和8例正常人脑组织中MAGE-D4 mRNA的表达,分析MAGE-D4 mRNA的表达与脑膜瘤患者临床病理特征的关系。结果 MAGE-D4 mRNA在脑膜瘤组织中的阳性表达率为58.33%(21/36),明显高于正常人脑组织中的阳性表达率12.50%(1/8)(P<0.05);脑膜瘤组织中MAGE-D4 mRNA的表达与性别、年龄、肿瘤大小和病理类型等临床病理特征无关(P>0.05)。 结论 在脑膜瘤组织中MAGE-D4的表达率较高,提示MAGE-D4可能成为脑膜瘤免疫治疗的靶抗原。

Abstract:

Objective  To explore the expression and possible significance of melanoma-associated antigen MAGE-D4 in human meningioma tissues. Methods Expression of MAGE-D4 was determined by RT-PCR in 36 meningiomas tissues and 8 normal brain tissues. The associations between MAGE-D4 expression and clinico-pathological features was statistically evaluated. Results Expression rates of MAGE-D4 mRNA was significantly higher in meningioma tissues(58.33% and 12.50%,respectively)than that in normal brain tissues(P<0.05). MAGE-D4 mRNA expression wasn′t related to gender,age,tumor size and histological types(P>0.05). Conclusion MAGE-D4 mRNA was significantly expressed in meningioma tissues,which may serve as a target antigen for meningioma immunotherapy.
