Superimposition of Drosha and Dicer.

open access: yes, 2019
Front (left) and side (right) views of superimposition of Drosha (sand) upon Dicer (deep blue). Connector domain of Drosha is colored firebrick and of Dicer green-forest.

Glycogen synthase kinase 3 beta (GSK3β) phosphorylates the RNAase III enzyme Drosha at S300 and S302. [PDF]

open access: yesPLoS ONE, 2011
The canonical microRNA (miRNA) pathway commences with the enzymatic cleavage of the primary gene transcript (pri-miRNA) by the RNAase III enzyme Drosha in the nucleus into shorter pre-miRNA species that are subsequently exported to the cytoplasm for ...

ECM Substrates Impact RNAi Localization at Adherens Junctions of Colon Epithelial Cells

open access: yesCells, 2022
The extracellular matrix (ECM) plays crucial roles in tissue homeostasis. Abnormalities in ECM composition are associated with pathological conditions, such as fibrosis and cancer.

Interplay Between Epigenetics and Reactive Oxygen Species in Tumor Radioresistance: Mechanisms and Therapeutic Strategies for Radiotherapy

open access: yesCancer Medicine, Volume 15, Issue 10, October 2026.
ABSTRACT Radiotherapy efficacy is constrained by tumor radioresistance, which arises in part from the interplay between reactive oxygen species (ROS) and epigenetic regulation. This review systematically synthesizes the bidirectional “epigenetics‐ROS interactive network” that governs tumor radiosensitivity. We propose that this network operates through

Transcription factor binding sites are highly enriched within microRNA precursor sequences

open access: yesBiology Direct, 2011
Background Transcription factors are thought to regulate the transcription of microRNA genes in a manner similar to that of protein-coding genes; that is, by binding to conventional transcription factor binding site DNA sequences located in or near ...

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

open access: yesThe Kaohsiung Journal of Medical Sciences, Volume 42, Issue 10, October 2026.
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

The amount of 3’UTR-derived piRNAs does not decrease in follicle cells lacking Drosha activity.

open access: yes, 2015
Normalized profiles of ovarian piRNAs (sense: up (red); antisense: down (blue)) that map to the traffic jam, jim and GC32000 3'UTRs in tj-GAL4>WT-Drosha* and tj-GAL4>TN-Drosha* libraries (upper panels), in tj-GAL4>WT-Drosha and tj-GAL4>TN-Drosha (middle ...

The microRNA processor DROSHA is a candidate gene for a severe progressive neurological disorder [PDF]

open access: yes, 2022
DROSHA encodes a ribonuclease that is a subunit of the Microprocessor complex and is involved in the first step of microRNA (miRNA) biogenesis. To date, DROSHA has not yet been associated with a Mendelian disease.

Nucleases and Their Inhibitors: Exploring Biological Roles, Industrial Applications, and Challenges in Heterologous Expression

open access: yesBiotechnology Journal, Volume 21, Issue 9, September 2026.
Graphical Abstract and Lay Summary Intracellular nucleases, depicted as blue circles in a nucleosome, hydrolyze phosphodiester bonds, repair damaged DNA using DNA base excision repair (BER), mismatch repair (MMR), and homologous recombination (HR), and are involved in DNA replication.
