摘要: 目的:探讨重组人白细胞介素17A (IL-17A)对结肠癌细胞生长的影响,并阐明其作用机制。方法:将结肠癌SW480细胞分为对照组和实验组,对照组细胞未经处理,实验组细胞加入50 μg·L-1重组人IL-17A。采用CKK-8法检测2组SW480细胞增殖活性,采用ELISA法检测2组细胞中IL-17A水平,Western blotting法检测2组SW480细胞中信号传导及转录激活因子3(STAT3)和磷酸化信号传导及转录激活因子3(p-STAT3)蛋白表达水平。结果:与对照组比较,实验组细胞增殖活性明显升高(P<0.05)。与对照组比较,实验组SW480细胞中IL-17A水平、STAT3和p-STAT3蛋白表达水平明显升高(P<0.01)。结论:重组人IL-17A可刺激结肠癌细胞SW480细胞的生长,其作用机制可能与激活STAT3信号通路有关。

Abstract: Objective: To explore the effect of recombinant human interleukin-17AI (IL-17A)on the growth of colon cancer cells,and to investigate the related mechanism.Methods: The colon cancer SW480 cells were divided into control group and experimental group. The SW480 cells in control group were untreated and the SW480 cells in experimental group were added with 50μg·L-1IL-17A. The proliferation abilities of SW480 cells in two groups were detected by CKK-8 method. The levels of IL-17A in the SW480 cells in two groups were detected by ELISA,and the expression levels of signal transducers and activators of transcription 3(STAT3 ) and p-signal transducers and activators of transcriptions 3(p-STAT3) were examined by Western blotting methed.Results: Compared with control group,the proliferation ability of the SW480 cells in experimental group was increased (P<0.05).The level of IL-17A in the SW480 cells in experimental group was significantly higher than that in control group (P<0.01). Compared with control group,the expression levels of STAT3 and p-STAT3 proteins in the SW480 cells in experimental group were significantly higher than those in control group(P<0.01).Conclusion: Recombinant protein IL-17A can stimulate the growth of colon cancer SW480 cells,which may be related to the activation of STAT3 signaling pathway.

Key words: interleukin-17A, colon cancer cells, signal pathway, signal transducers and activators of transcription
