Structural Differences between Pri-miRNA Paralogs Promote Alternative Drosha Cleavage and Expand Target Repertoires

Cell Reports, 2019
Summary: MicroRNA (miRNA) processing begins with Drosha cleavage, the fidelity of which is critical for downstream processing and mature miRNA target specificity.

The Role of DICER and DROSHA Gene Expression in Assessment of Hashimoto Thyroiditis [PDF]

Zagazig University Medical Journal
Background: Hashimoto thyroiditis is autoimmune condition that destroys thyroid follicular cells by immune-mediated mechanisms through the development of anti-thyroid antibodies and T lymphocytes activation , which causes ongoing fibrosis of the thyroid.

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

Animal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

Engineering double-stranded RNA binding activity into the Drosha double-stranded RNA binding domain results in a loss of microRNA processing function.

PLoS ONE, 2017
Canonical processing of miRNA begins in the nucleus with the Microprocessor complex, which is minimally composed of the RNase III enzyme Drosha and two copies of its cofactor protein DGCR8.

The conserved single-cleavage mechanism of animal DROSHA enzymes

Communications Biology, 2021
Recently, the human RNase III enzyme DROSHA had been shown to exhibit single cleavage activity. Nguyen et al. report that this molecular mechanism of DROSHA is conserved in worms and flies, suggesting a common feature of animal DROSHAs.

Modulation of MicroRNA Processing by Dicer via Its Associated dsRNA Binding Proteins

Non-Coding RNA, 2021
MicroRNAs (miRNAs) are small non-coding RNAs that are about 22 nucleotides in length. They regulate gene expression post-transcriptionally by guiding the effector protein Argonaute to its target mRNA in a sequence-dependent manner, causing the ...

Epigenetic Regulation in the Pathogenesis of Renal Inflammation: Insights and Therapeutic Potentials

iNew Medicine, EarlyView.
ABSTRACT Renal inflammation is a common pathological process in various kidney diseases, often initiated by factors such as toxins, ischemia, or autoimmune reactions. This inflammatory response can result in structural damage and a rapid decline in renal function.

Emerging roles of DROSHA beyond primary microRNA processing [PDF]

RNA Biology, 2017
DROSHA is the catalytic subunit of the Microprocessor complex, which initiates microRNA (miRNA) maturation in the nucleus by recognizing and cleaving hairpin precursors embedded in primary transcripts. However, accumulating evidence suggests that not all hairpin substrates of DROSHA are associated with the generation of functional small RNAs.

miR‐9 Restricts Insulin Secretion by Targeting Rab34, Which Mediates Lysosomal Degradation of Proinsulin

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Insulin secretion is a complex, vesicular transport process. Rab34 is a key regulator of intracellular vesicle transport; however, its role in insulin secretion has not yet been reported. miRNA‐9 is vital for the development and progression of the diagnosis and treatment of type 2 diabetes. This study aimed to investigate whether miR‐9 targets
