Interleukin-17 receptor (IL-17RA) is essential for proinflammatory cytokine IL-17-mediated pathogenesis of various tumors. IL-17RA is upregulated by some proinflammatory cytokines such as IL-21 and IL-15 and downregulated by IL-2, while the effect of IL-1β, IL-6, IL-8, TNF-α on IL-17RA expression in non-small cell lung caner (NSCLC) remains unknown. Our findings revealed that IL-17RA mRNA was increased in NSCLC tissues compared with the corresponding peritumor tissues (P = 0.0039) and high expression of IL-17RA protein in human NSCLC tissues was significantly associated with histological subtype, primary tumor size and clinical stages (P = 0.033, 0.033 and 0.011, respectively). IL-17RA mRNA expression was positively related to IL-1β, IL-6, IL-8, TNF-α mRNA expression (P = 0.013, 0.0001, 0.002 and 0.010 respectively) in NSCLC tissues. Furthermore, IL-1β, IL-6, IL-8, TNF-α upregulated IL-17RA mRNA and protein in A549 and H460 cells (all P < 0.05). It is suggested that IL-1β, IL-6, IL-8, TNF-α promoted IL-17RA expression in NSCLC and they may involve in IL-17RA signaling in NSCLC.
白细胞介素-17受体(IL-17RA)对于促炎细胞因子IL-17介导的各种肿瘤发病机制至关重要。IL-17RA会被一些促炎细胞因子如IL-21和IL-15上调,而被IL-2下调,然而IL-1β、IL-6、IL-8、TNF-α对非小细胞肺癌(NSCLC)中IL-17RA表达的影响仍不清楚。我们的研究结果显示,与相应的肿瘤旁组织相比,NSCLC组织中IL-17RA mRNA增加(P = 0.0039),并且人NSCLC组织中IL-17RA蛋白的高表达与组织学亚型、原发肿瘤大小和临床分期显著相关(分别为P = 0.033、0.033和0.011)。在NSCLC组织中,IL-17RA mRNA表达与IL-1β、IL-6、IL-8、TNF-α mRNA表达呈正相关(分别为P = 0.013、0.0001、0.002和0.010)。此外,IL-1β、IL-6、IL-8、TNF-α上调了A549和H460细胞中IL-17RA mRNA和蛋白的表达(所有P < 0.05)。提示IL-1β、IL-6、IL-8、TNF-α促进了NSCLC中IL-17RA的表达,并且它们可能参与了NSCLC中的IL-17RA信号传导。
