DICER1 and schizophrenia: Given the critical role of DICER1 in the formation of mature miRNAs, it is notable that 13 sets of genes that were targets of various miRNAs and one set involving brain miRNA biogenesis in a mouse model of schizophrenia were significantly enriched, suggesting that genes that are targets of different miRNAs were differentially expressed in PTSD&Dep (Supplementary Table 1).
