title: Aberrant expression of serum miRNAs in schizophrenia.
abstract: The circulating miRNAs are sufficiently stable and detectable to serve as clinical biomarkers as recent studies have revealed that the aberrant expression of circulating miRNAs can directly reflect disease status. Based on the analysis of the data (using miRanda software, TargetScan software and SOLID high-throughput sequencing) obtained from the literature, Schizophrenia Gene database, NCBI database, the quantification of the nine miRNAs in the serum samples of 115 patients suffering from schizophrenia and 40 healthy individuals using qRT-PCR and semi-nested qRT-PCR was conducted. The results suggested that the miR-181b, miR-219-2-3p, miR-346, miR-195, miR-1308, miR-92a, miR-17, miR-103 and let-7g are the key players to reflect the schizophrenia illnesses status and may serve as candidate biomarkers for diagnosis of schizophrenia. In addition, we also found that the risperidone improved the serum miR-346 level of schizophrenia significantly, and therefore may not be an effective drug in regulating serum miR-346 level of schizophrenia. Furthermore, the expression level of serum miRNAs levels and schizophrenia patients were regardless of family history subtypes, ages, and gender. Collectively, these findings suggested that the serum miRNAs have strong potential to reflect schizophrenia disease status. To the best of our knowledge, this is the first report demonstrating the analysis of the circulating miRNAs in schizophrenia.
