目的:检测与精神分裂症相关的血浆中差异表达微小 RNA (miRNA),探寻有精神分裂症诊断价值的生物标记。方法:选择6例首发、未用药的符合美国精神障碍诊断与统计手册第4版(DSM-IV)诊断的精神分裂症患者及6例年龄、性别匹配的正常对照者(筛查样本),采用 TaqMan Array 人类微小 RNA 芯片(TaqMan Array Human MicroRNA A +B Cards Set v3.0)高通量检测了754个 miRNA (SangerhumanmiRBase v14)的血浆表达水平,并用 SAM 软件的 t 检验分析病例和对照组间 miRNA 表达水平的差异;进而在独立的25例精神分裂症患者和18例正常对照(验证样本)中,采用实时荧光定量 PCR (RT-PCR)方法进行检测与分析,采用 t 检验比较两组 miRNA 表达水平差异。结果:筛查样本中精神分裂症患者有20个 miRNA 的表达水平低于正常对照,并通过 FDR 多重比较校正;根据差异表达 miRNA 的显著性和既往文献报道,选择其中8个差异表达 miRNA 进行独立样本验证,发现这些 miRNA 在验证样本的精神分裂症血浆中表达下调,且其中4个 miRNA:hsa-miR-15b-5p 经过 FDR 多重比较校正后仍有统计意义。结论:精神分裂症患者血浆中有多个 miRNA 低表达,这些低表达的 miRNA 对精神分裂症的诊断有参考意义。
目的:檢測與精神分裂癥相關的血漿中差異錶達微小 RNA (miRNA),探尋有精神分裂癥診斷價值的生物標記。方法:選擇6例首髮、未用藥的符閤美國精神障礙診斷與統計手冊第4版(DSM-IV)診斷的精神分裂癥患者及6例年齡、性彆匹配的正常對照者(篩查樣本),採用 TaqMan Array 人類微小 RNA 芯片(TaqMan Array Human MicroRNA A +B Cards Set v3.0)高通量檢測瞭754箇 miRNA (SangerhumanmiRBase v14)的血漿錶達水平,併用 SAM 軟件的 t 檢驗分析病例和對照組間 miRNA 錶達水平的差異;進而在獨立的25例精神分裂癥患者和18例正常對照(驗證樣本)中,採用實時熒光定量 PCR (RT-PCR)方法進行檢測與分析,採用 t 檢驗比較兩組 miRNA 錶達水平差異。結果:篩查樣本中精神分裂癥患者有20箇 miRNA 的錶達水平低于正常對照,併通過 FDR 多重比較校正;根據差異錶達 miRNA 的顯著性和既往文獻報道,選擇其中8箇差異錶達 miRNA 進行獨立樣本驗證,髮現這些 miRNA 在驗證樣本的精神分裂癥血漿中錶達下調,且其中4箇 miRNA:hsa-miR-15b-5p 經過 FDR 多重比較校正後仍有統計意義。結論:精神分裂癥患者血漿中有多箇 miRNA 低錶達,這些低錶達的 miRNA 對精神分裂癥的診斷有參攷意義。

Objective:To detect differentiallyexpressed microRNAs (miRNAs)in plasma of schizophrenia and explore biomarker for diagnosis of schizophrenia.Methods:The discovery cohort tincluded 6 patients with schizophrenia meeting diagnostic criteria of schizophrenia of the Diagnostic and Statistical Manual of Mental Disor-der,Fourth Edition (DSM-IV),as well as 6 healthy control subjects,whose age and gender were matched to pa-tients.The expression of 754 miRNAs (Sanger human miRBase v14)in the discovery cohort was investigated by Taqman Array (Human MicroRNA A +B Cards Set v3.0).Then the quantitative reverse-transcription polymor-phism chain reaction (qRT-PCR)assay was conducted to validate differentially expressed miRNAs in an independ-ent replication cohort,which included 25 schizophrenia patients and 18 healthy control subjects.The student's t-tests were used to analyze the differential expression of miRNA between schizophrenia patients and controls.All analyses were performed in Significance Analysis of Microarrays (SAM)software.Results:Twenty down-regulated miRNAs were observed in discovery cohort.Four miRNAs,hsa-miR-15b-5p were down-regulated in both discovery and rep-licated cohorts.Conclusion:The present study suggests that aberrant expression of miRNA might be of potential im-portance as biomarkers in the diagnosis of schizophrenia.
