Individuals with 22q11.2 microdeletions show behavioral and cognitive deficits and are at high risk of developing schizophrenia. We analyzed an engineered mouse strain carrying a chromosomal deficiency spanning a segment syntenic to the human 22q11.2 locus. We uncovered a previously unknown alteration in the biogenesis of microRNAs (miRNAs) and identified a subset of brain miRNAs affected by th...
MicroRNAs are a class of non-coding RNAs that regulate gene expression at the post-transcriptional level. The major proteins of the canonical microRNA biogenesis pathway in human are: Drosha, DGCR8, DDX5, DDX17, Exportin 5, Dicer and Argonaute 2. Recent studies suggest that gene expression of some canonical microRNA biogenesis components could be regulated by steroid hormones. Furthermore, vari...
GW bodies (GWBs), or mammalian P bodies, proposed to be involved in messenger RNA storage and/or degradation, have recently been linked to RNA interference and microRNA (miRNA) processing. We report that endogenous let-7 miRNA co-precipitates with the GW182 protein complex. In addition, knockdown of two proteins, Drosha and its protein partner DGCR8, which are vital to the generation of mature ...
MicroRNA (miRNA)-mediated gene silencing is one of the major regulatory pathways in eukaryotes. Much effort has been made to identify the factors involved in the pathway, and our understanding of RNA silencing has significantly advanced in recent years. Our group has been working on some of the issues regarding miRNA biogenesis and, in this paper, we summarize what we and other workers in the f...
