<qa>  What is the name of the miRNA-30e precursor?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.
