摘要: 摘要: 目的 研究白细胞介素 (IL) -17A 及其受体 (IL-17RA) 在不同恶性程度胶质瘤中表达的差异。方法 收集胶质瘤患者 50 例, 按照世界卫生组织的分类系统分为Ⅰ级 12 例, Ⅱ级 18 例, Ⅲ级 13 例, Ⅳ级 7 例。取患者外周血以及胶质瘤组织, 荧光实时定量 PCR 检测 IL-17A 及 IL-17RA 的 mRNA 水平, 采用免疫组化和 Western blot 检测 IL-17A 及 IL-17RA 的蛋白表达水平。结果 免疫组化染色结果显示, 随着胶质瘤恶性程度增加, IL-17A 及其受体 IL-17RA 表达增加。外周血中, IL-17A 及其受体 IL-17RA 的 mRNA 水平随着胶质瘤恶性程度增加而上升 (F 分别为 8.96、 10.34, 均 P<0.05)。胶质瘤组织中 IL-17A 及其受体 IL-17RA 的 mRNA 水平随着胶质瘤恶性程度增加而上升 (F 分别为 11.21、 14.11, 均 P<0.05)。在外周血和胶质瘤组织中, IL-17A 及其受体 IL-17RA 的蛋白水平随着胶质瘤恶性程度增加也上升 (外周血 F 分别为 9.90、 11.80, 均 P<0.05; 胶质瘤组织 F 分别为 8.15、 14.46,均 P< 0.05)。结论 IL-17A 及其受体 IL-17RA 的表达与胶质瘤恶性程度呈正相关性。

Abstract: Abstract: Objective To explore the expressions of interleukin (IL)- 17A and its receptor IL- 17RA in different degrees of malignant gliomas. Methods Fifty patients with glioma were collected in this study. Accordance to the World Health Organization Classification System, patients were classified by malignancy grade, including grade Ⅰ (n=12), grade Ⅱ (n=18), grade Ⅲ (n=13) and grade Ⅳ (n=7). The glioma tissue and peripheral blood samples of patients were obtained for detecting the expression levels of IL- 17A and IL- 17RA mRNA by using immunohistochemistry, quantitative real- time PCR. Western blot assay was used to detect expressions of IL- 17A and IL- 17RA in both the macroscopic (immunohistochemistry) and molecular levels (mRNA and protein). Results Immunohistochemical staining showed that the expression levels of IL-17A and its receptor IL-17RA increased with the increase of the malignant degree of gliomas. The mRNA levels of IL-17A and IL-17RA receptors in peripheral blood were up-regulated with the increasing malignancy grade of glioma (F=8.96, P<0.05; F=10.34, P<0.05). The mRNA levels of IL-17A and IL-17RA in glioma tissues were up-regulated with the increasing malignancy grade of glioma (F=11.21, P<0.05; F=14.11, P<0.05). The protein levels of IL-17A and IL-17RA in peripheral blood and glioma tissues were also up-regulated with the increasing malignancy grade of glioma (in peripheral blood: F=9.90, P<0.05; F=11.80, P<0.05; and in gliomas tissues: F=8.15, P<0.05; F=14.46, P< 0.05). Conclusion The expressions of IL-17A and IL-17RA receptor are positively correlated with malignancy grade of glioma. These results provide some reference for clinical diagnosis of malignant gliomas.
