丙型肝炎病毒和丝氨酸蛋白酶抑制因子Kazal1型的关系研究

Relationship between hepatitis C virus and serine protease inhibitor Kazal1

目的探讨丙型肝炎病毒(hepatitis Cvirus,HCV)对丝氨酸蛋白酶抑制因子Kazal1型(SPINK1)表达的影响及其临床意义。方法采用逆转录聚合酶链反应(RT-PCR)和Western blot印迹法检测JFH-1株HCV病毒感染的Huh7.5.1细胞及其对照细胞中SPINK1mRNA和蛋白的表达水平,酶联免疫吸附试验(ELISA)检测细胞上清及丙肝患者血清中SPINK1的含量,分析健康对照者及丙肝患者SPINK1血清含量的差异。结果HCV感染的Huh7.5.1细胞中SPINK1mRNA和蛋白的表达水平较对照细胞高;SPINK1血清含量在丙肝患者明显高于健康体检者(P=0.016)。结论HCV能够上调SPINK1的表达。

Objective To explore the effect of hepatitis C virus (HCV) on the expression of serine protease inhibitor Kazal1 (SPINK1) and its clinical implication. Methods mRNA and protein expression of SPINK1 in Huh7.5.1 cells infected by HCV JFH-1 and the control cells were measured by RT-PCR and western blotting, SPINK1 levels in the cell supernatants and sera of HCV patients were measured by enzyme-linked immunosorbent assay (ELISA), the difference of SPINK1 levels between healthy controls and HCV patients was analyzed. Results Expression of SPINK1 mRNA and protein was higher in Huh7.5.1 cells infected by HCV JFH-1 than in the control cells, serum SPINK1 levels was much higher in HCV patients than in healthy controls (P=0.016). Conclusions HCV can upregulate the expression of SPINK1.
