DICER1 and schizophrenia: Interestingly, DICER1 mRNA level was found to be upregulated in lymphoblastoid cell lines of schizophrenia patients35 and also upregulated in the dorsolateral prefrontal cortex of schizophrenia patients36, suggesting the possibility of a positive correlation of DICER1 expression between blood and brain; however, this remains to be investigated.
