摘要

摘要: 目的探讨自噬相关基因LC-3 mRNA、Beclin-1 mRNA、Agt-3 mRNA、Agt-5 mRNA、Agt-12 mRNA和Agt-16L1 mRNA在系统性硬化症(systemic sclerosis,SSc)患者外周血单个核细胞(peripheral blood mononuclear cell,PBMC)中的表达及临床意义。方法选取2018年4月—2019年3月于川北医学院附属医院就诊的SSc患者(SSc组)29例和年龄、性别相匹配的对照组(健康体检者)29例,采用RT-PCR检测自噬相关基因在PBMC中的表达水平。运用SPSS 19.0统计学软件比较组间自噬相关基因的表达,分析自噬相关基因与临床资料之间的关系,P<0.05为差异有统计学意义。结果 (1)与对照组相比,自噬相关基因LC-3、Beclin-1和Agt-3在SSc组中表达增加[LC-3:0.77(0.51,1.00)×10^-3 vs. 0.46(0.37,0.63)×10^-3;Beclin-1:6.13(5.01,7.88)×10^-3 vs. 4.76(3.43,5.34)×10^-3;Agt-3:15.67(11.52,23.66)×10^-3 vs. 8.65(7.44,11.23)×10^-3],而自噬相关基因Agt-5、Agt-12及Agt-16L1组间差异无统计学意义;(2)LC-3在抗核小体抗体、抗SSA/Ro抗体阳性患者中表达更高;(3)LC-3的相对表达量与SSc患者的年龄、ESR呈正相关,r值分别为0.662、0.428(均P<0.05)。结论自噬相关基因在SSc患者外周血单个核细胞中表达增加,并与年龄、ESR、抗体相关,提示自噬是SSc发病机制中的一个重要特征。

Abstract: Objective To investigate the expression and clinical significance of autophagy-related genes LC-3 mRNA, Beclin-1 mRNA, Agt-3 mRNA, Agt-5 mRNA, Agt-12 mRNA and Agt-16 L1 mRNA in peripheral blood mononuclear cell(PBMC) of systemic sclerosis(SSc). Methods Twenty-nine cases of SSc and 29 cases of normal control were received from the Affiliated Hospital of North Sichuan Medical College, and autophagy-related genes were detected by RT-PCR. SPSS 19.0 statistical software was used to compare the expression of autophagy-related genes between groups and analyze the relationship between autophagy-related genes and clinical data, P<0.05 was considered statistically significant. Results (1)LC-3, Beclin-1, and Agt-3 were highly expressed in SSc compared with normal control [LC-3:0.77(0.51,1.00)×10^-3 vs. 0.46(0.37,0.63)×10^-3; Beclin-1: 6.13(5.01,7.88) ×10^-3 vs. 4.76(3.43,5.34)×10^-3;Agt-3:15.67(11.52,23.66)×10^-3 vs. 8.65(7.44,11.23)×10^-3], however Agt-5, Agt-12 and Agt-16 L1 of autophagy-related genes were not statistically significant.(2)LC-3 high expressed in SSc with the positive of anti-nucleosome antibody and the positive of anti-SSA/Ro antibody.(3)LC-3 was positively correlated with Age and ESR, and the values of r were 0.662, 0.428(all P<0.05). Conclusion Autophagy-related genes were increased in PBMC of SSc, and were correlated with age, ESR and autoantibody, suggested that autophagy is a key feature in the pathogenesis of systemic sclerosis.
