摘要:

目的  研究涎腺良性肿瘤组织、恶性肿瘤组织和涎腺炎症中人β-防御素-2(HBD-2)mRNA和蛋白的表达特征。方法  对不同涎腺组织,采用聚合酶链反应(PCR)、实时聚合酶链反应(Real-Time PCR)和免疫组化检测HBD-2的表达,并分析HBD-2 mRNA和蛋白在涎腺良性肿瘤组织、恶性肿瘤组织、炎症组织和正常涎腺组织中的表达差异。结果  与涎腺正常组织比较,良性肿瘤组HBD-2 mRNA表达量为其6.468倍,显著高于涎腺正常组织组(P<0.05);恶性肿瘤组为其0.334倍,显著低于涎腺正常组织组(P<0.05);涎腺炎症组为其10.563倍,显著高于涎腺正常组织组(P<0.05)。HBD-2不仅在这些组织的细胞质中有表达,而且在恶性组织中的细胞核也有表达。结论  HBD-2在涎腺良性肿瘤组织及涎腺炎症组织中高表达,在涎腺恶性肿瘤组织中低表达,其蛋白发生核转移。

Abstract:

Objective  To investigate the expression characteristics of human beta-defensin-2 (HBD-2) mRNA and pro-tein in salivary gland benign and malignant tumor tissues, as well as in salivary gland inflammation. Methods  The expres-sion of HBD-2 in salivary gland benign tumor, salivary gland cancer, inflammation tissues and normal salivary gland tissues were detected by polymerase chain reaction (PCR), real-time polymerase chain reaction (Real-Time PCR) and immunohisto-chemical. The differences expression of HBD-2 mRNA and protein were analyzed. Results  RT-PCR results showed that HBD-2 mRNA expression in salivary gland benign tumors, salivary gland cancer, and inflammation tissues was 6.468-, 0.334-, and 10.563-fold higher than that in normal tissues, respectively (P<0.05). HBD-2 was expressed in the nuclei of these organs and malignant tissues. Conclusion  HBD-2 mRNA and protein expressions are significantly increased in salivary gland benign tumor tissues and inflammation tissues compared with those in normal salivary gland tissues, but are significantly decreased in salivary gland cancer. The protein nuclear transfer in salivary gland cancer tissues is also significantly increased.
