Intronic microRNA precursors that bypass Drosha processing [PDF]

open access: yesNature, 2007
MicroRNAs (miRNAs) are approximately 22-nucleotide endogenous RNAs that often repress the expression of complementary messenger RNAs. In animals, miRNAs derive from characteristic hairpins in primary transcripts through two sequential RNase III-mediated cleavages; Drosha cleaves near the base of the stem to liberate a approximately 60-nucleotide pre ...

Drosha: a new tumor suppressor in pineoblastoma. [PDF]

open access: yesGenes Dev
To investigate the pathogenesis and target the vulnerability of human pineoblastoma, researchers have developed multiple genetically engineered mouse models that represent distinct molecular subtypes of the disease. In this issue ofGenes & Development, Fraire and colleagues (doi:10.1101/gad.352485.124) examined the roles of key microRNA (miRNA ...

PLK1 regulates microRNA biogenesis through Drosha phosphorylation

open access: yes, 2023
Polo-Like Kinase 1 (PLK1), a key mediator of cell-cycle progression, is associated with poor prognosis and is a therapeutic target in a number of malignancies.

Expression levels of Drosha and Dicer enzymes and DGCR8 protein in pre-eclamptic patients [PDF]

open access: yesMajallah-i Zanān, Māmā̓ī va Nāzā̓ī-i Īrān, 2018
Introduction: Pre-eclampsia is a serious problem of pregnancy that is associated with proteinuria and increased blood pressure in the second half of pregnancy. It is one of the three leading causes of maternal and fetal mortality. Dysregulated expression

Drosha mediates destabilization of Lin28 mRNA targets [PDF]

open access: yesCell Cycle, 2012
Lin28 plays important roles in development, stem cell maintenance, oncogenesis and metabolism. As an RNA-binding protein, it blocks the biogenesis primarily of let-7 family miRNAs and also promotes translation of a cohort of mRNAs involved in cell growth, metabolism and pluripotency, likely through recognition of distinct sequence and structural motifs

Structural basis for Dicer-like function of an engineered RNase III variant and insights into the reaction trajectory of two-Mg2+-ion catalysis

open access: yesRNA Biology, 2022
The RNase III family of dsRNA-specific endonucleases is exemplified by prokaryotic RNase III and eukaryotic Rnt1p, Drosha, and Dicer. Structures of Aquifex aeolicus RNase III (AaRNase III) and Saccharomyces cerevisiae Rnt1p (ScRnt1p) show that both ...

Cytoplasmic Drosha activity generated by alternative splicing [PDF]

open access: yesNucleic Acids Research, 2016
RNase III enzyme Drosha interacts with DGCR8 to form the Microprocessor, initiating canonical microRNA (miRNA) maturation in the nucleus. Here, we re-evaluated where Drosha functions in cells using Drosha and/or DGCR8 knock out (KO) cells and cleavage reporters.

Essential role of the amino-terminal region of Drosha for the Microprocessor function

open access: yes, 2022
Summary: The ribonuclease (RNase) III enzyme Drosha enables processing of microRNA (miRNA) primary transcripts (pri-miRNAs) and control of ribosomal protein (RP) biogenesis by the Microprocessor.

DROSHA Knockout Leads to Enhancement of Viral Titers for Vectors Encoding miRNA-Adapted shRNAs

open access: yesMolecular Therapy: Nucleic Acids, 2018
RNAi-based gene therapy using miRNA-adapted short hairpin RNAs (shRNAmiR) is a powerful approach to modulate gene expression. However, we have observed low viral titers with shRNAmiR-containing recombinant vectors and hypothesized that this could be due ...
