BRCA1 regulates microRNA biogenesis via the DROSHA microprocessor complex

MicroRNAs (miRNAs) are noncoding RNAs that function as key posttranscriptional regulators of gene expression. miRNA maturation is controlled by the DROSHA microprocessor complex. However, the detailed mechanism of miRNA biogenesis remains unclear. We show that the tumor suppressor breast cancer 1 (BRCA1) accelerates the processing of miRNA primary transcripts. BRCA1 increased the expressions of...

A novel role for GSK3β as a modulator of Drosha microprocessor activity and MicroRNA biogenesis

Regulation of microRNA (miR) biogenesis is complex and stringently controlled. Here, we identify the kinase GSK3β as an important modulator of miR biogenesis at Microprocessor level. Repression of GSK3β activity reduces Drosha activity toward pri-miRs, leading to accumulation of unprocessed pri-miRs and reduction of pre-miRs and mature miRs without altering levels or cellular localisation of mi...

Dysregulation of microRNA biogenesis in cancer: the impact of mutant p53 on Drosha complex activity.

A widespread decrease of mature microRNAs is often observed in human malignancies giving them potential to act as tumor suppressors. Thus, microRNAs may be potential targets for cancer therapy. The global miRNA deregulation is often the result of defects in the miRNA biogenesis pathway, such as genomic mutation or aberrant expression/localization of enzymes and cofactors responsible of miRNA ma...

FUS stimulates microRNA biogenesis by facilitating co-transcriptional Drosha recruitment.

microRNA abundance has been shown to depend on the amount of the microprocessor components or, in some cases, on specific auxiliary co-factors. In this paper, we show that the FUS/TLS (fused in sarcoma/translocated in liposarcoma) protein, associated with familial forms of Amyotrophic Lateral Sclerosis (ALS), contributes to the biogenesis of a specific subset of microRNAs. Among them, species w...

MicroRNA Biogenesis: Drosha Can't Cut It without a Partner

The ribonuclease Drosha requires a dedicated double-stranded RNA binding protein to convert long, nuclear primary microRNA transcripts into shorter pre-microRNA stem-loops, the cytoplasmic precursors from which mature microRNAs are ultimately excised.
