Ad36感染对维吾尔族肥胖患者progranulin 表达的调节作用

目的:探讨腺病毒36型(Ad36)感染对维吾尔族肥胖患者颗粒蛋白前体(progranulin)表达的调节作用。方法根据肥胖诊断标准将维吾尔族人群样本分为肥胖组(115)与非肥胖组(117),收集血清标本232份,脂肪标本102份。血清中和反应法检测样本血清中的 Ad36抗体。采用实时荧光定量 PCR(real time quantitative-PCR)方法检测研究对象大网膜和皮下的脂肪组织 progranulin 的 mRNA 表达水平,利用酶联免疫吸附实验(ELISA)测定血清progranulin 的蛋白表达水平。免疫组化方法检测脂肪组织巨噬细胞 CD68蛋白表达,了解巨噬细胞浸润情况。...

Summary:目的:探讨腺病毒36型(Ad36)感染对维吾尔族肥胖患者颗粒蛋白前体(progranulin)表达的调节作用。方法根据肥胖诊断标准将维吾尔族人群样本分为肥胖组(115)与非肥胖组(117),收集血清标本232份,脂肪标本102份。血清中和反应法检测样本血清中的 Ad36抗体。采用实时荧光定量 PCR(real time quantitative-PCR)方法检测研究对象大网膜和皮下的脂肪组织 progranulin 的 mRNA 表达水平,利用酶联免疫吸附实验(ELISA)测定血清progranulin 的蛋白表达水平。免疫组化方法检测脂肪组织巨噬细胞 CD68蛋白表达,了解巨噬细胞浸润情况。结果①肥胖患者 Ad36感染率(54/115,47.0%)明显高于非肥胖者(38/117,32.5%),差异有统计学意义(P <0.05)。②Ad36感染的肥胖组血清 progranulin 的 蛋 白 表达水平 (408.45±156.92)显著高于非肥胖组(326.11±158.60),差异有统计学意义(P <0.05);两组的腹部大网膜、皮下脂肪组织 progranulin mRNA 表达水平差异无统计学意义(P 均>0.05)。③Ad36感染的肥胖组巨噬细胞浸润(14730.16±2227.39)明显高于非肥胖组(10786.50±2772.80),差异有统计学意义(P <0.05)。结论Ad36感染可能与维吾尔族肥胖发生有关,其机制可能为通过调节血清 progranulin 的蛋白表达水平而实现。

Objective To investigate the regulation of adenovirus type 36 infection on precursor protein particles progranulin expression in Uygur obese patients.Methods Based on the diagnostic criteria of obesity,the samples were divided into obese group and non-obese group.Serum neutralization test was used to detect the antibody of Ad36.The progranulin mRNA expressions in abdominal omental and subcutaneous adipose tissues were detected by real-time quantitative PCR.ELISA method was used to determine serum progranulin protein levels. CD68 protein expression of macrophage was detected by immunohistochemistry. Results ① In the Uygur population of our study,compared with that in the non-obese group (38/1 1 7,32.5%),the number of obese patients (54/1 1 5,47.0%)infected with Ad36 was significantly higher than that in non-obese group (P 〈0.05 ).② Serum prog
