Brief Summary

The aberrant expression of micro-RNAs (miRNAs) has been described in many human diseases, including schizophrenia (SZ). The previous work has indicated a strong genetic association between the miRNA-30e precursor (pre-miR-30e) and the risk of SZ. However, to date, few reports have focused on the expression level of the miR-30 family (miR-30s) and its networks of co-regulation in SZ, even in response to antipsychotic treatment. Given this, the investigator first constructed a hybrid miRNA-TF (transcription factor)-gene-PPI (protein-protein interactions) network focusing on miR-30s by bioinformatics technology. The investigator then selected several candidate miR-30s and key regulators for further validation. These candidates were then quantified by real-time quantitative PCR (qRT-PCR) in an independent cohort of 200 healthy controls and 200 drug-free SZ patients, among which were followed up by 12-week antipsychotic treatment. Furthermore, the investigator evaluated the correlation between the change in gene expression and the improvement of symptoms.

Outcome Measures

Primary Outcomes (1)

  • Number of schizophrenics with antipsychptic treatment who achieved remission assessed by PANSS.

    The clinical effects were assessed by trained and experienced psychiatrists with the Positive and Negative Syndrome Scale (PANSS) before and after 12-week treatment.

    Number of schizophrenics with 12-week antipsychptic treatment who achieved remission assessed by PANSS.
