DGCR8/miR-106 Axis Enhances Radiosensitivity of Head and Neck Squamous Cell Carcinomas by Downregulating RUNX3

open access: yesFrontiers in Medicine, 2020
Purpose: Head and neck squamous cell carcinoma (HNSCC) is the sixth most prevalent malignant tumor worldwide, and the radiotherapy effect is strongly associated with human papillomavirus (HPV) infection. Therefore, the aim of our study was to analyze the

Understanding Recognition of Primary MicroRNAs by Human Drosha/DGCR8 [PDF]

open access: yes, 2022
MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression by suppressing messenger RNAs. The RNase Drosha, as part of the Microprocessor complex, performs the initial processing step in miRNA biogenesis.

Genomic analysis suggests that mRNA destabilization by the microprocessor is specialized for the auto-regulation of Dgcr8.

open access: yesPLoS ONE, 2009
BackgroundThe Microprocessor, containing the RNA binding protein Dgcr8 and RNase III enzyme Drosha, is responsible for processing primary microRNAs to precursor microRNAs.

Molecular determinants that govern scaRNA processing by Drosha/DGCR8

open access: yesBiology Open, 2020
The Cajal body (CB) is a subnuclear domain that participates in the biogenesis of many different types of ribonucleoproteins (RNPs), including small nuclear RNPs (snRNPs), small Cajal body-specific RNPs (scaRNPs) and telomerase. Most scaRNAs, the RNA component of scaRNPs, accumulate in CBs.

Elevated p53 Activities Restrict Differentiation Potential of MicroRNA-Deficient Pluripotent Stem Cells

open access: yesStem Cell Reports, 2017
Summary: Pluripotent stem cells (PSCs) deficient for microRNAs (miRNAs), such as Dgcr8−/− or Dicer−/– embryonic stem cells (ESCs), contain no mature miRNA and cannot differentiate into somatic cells.

WBP2 inhibits microRNA biogenesis via interaction with the microprocessor complex

open access: yesLife Science Alliance, 2021
WBP2 protein blocks the microRNA biogenesis via physical interactions with the microprocessor complex, and reverts the tumor-suppressive role of DGCR8.

Elucidating the Role of Microprocessor Protein DGCR8 in Bending RNA Structures [PDF]

open access: yesBiophysical Journal, 2020
Although conformational dynamics of RNA molecules are potentially important in microRNA (miRNA) processing, the role of the protein binding partners in facilitating the requisite structural changes is not well understood. In previous work, we and others have demonstrated that nonduplex structural elements and the conformational flexibility they support

Epigenetic regulation of miR-29a/miR-30c/DNMT3A axis controls SOD2 and mitochondrial oxidative stress in human mesenchymal stem cells

open access: yesRedox Biology, 2020
The use of human mesenchymal stem cells (hMSCs) in clinical applications requires large-scale cell expansion prior to administration. However, the prolonged culture of hMSCs results in cellular senescence, impairing their proliferation and therapeutic ...

Noncanonical function of DGCR8 controls mESC exit from pluripotency [PDF]

open access: yesJournal of Cell Biology, 2017
Mouse embryonic stem cells (mESCs) deficient for DGCR8, a key component of the microprocessor complex, present strong differentiation defects. However, the exact reasons impairing their commitment remain elusive. The analysis of newly generated mutant mESCs revealed that DGCR8 is essential for the exit from the pluripotency state.
