Chicken Pulmonary MicroRNAs Targeting the PB2 (Segment 1) of Avian Influenza Virus

Animal Research and One Health, EarlyView.
The PB2 segment of H5N1 is essential for replication and host adaptation. We screened 200 miRNAs and identified five (gga‐miR‐17‐3p, gga‐miR‐29a‐5p, gga‐miR‐1718, gga‐miR‐16c‐5p, and gga‐miR‐1744‐5p) using thermodynamic stability of heteroduplex, seed sequence complementarity, conservation, and accessibility, offering insights into host antiviral ...

PUF Protein-mediated Deadenylation Is Catalyzed by Ccr4p [PDF]

Journal of Biological Chemistry, 2007
PUF proteins control gene expression by binding to the 3'-untranslated regions of specific mRNAs and triggering mRNA decay or translational repression. Here we focus on the mechanism of PUF-mediated regulation. The yeast PUF protein, Mpt5p, regulates HO mRNA and stimulates removal of its poly(A) tail (i.e. deadenylation).

Regulation of Synaptic Pumilio Function by an Aggregation-Prone Domain [PDF]

, 2010
We identified Pumilio (Pum), a Drosophila translational repressor, in a computational search for metazoan proteins whose activities might be regulated by assembly into ordered aggregates.

Bridging maternal effects and epitranscriptomics: A novel perspective in developmental biology

Developmental Dynamics, EarlyView.
Abstract Maternal effects, encompassing both genetic (maternally expressed gene products) and non‐genetic (maternal state) influences, are powerful determinants of offspring phenotype, yet their RNA‐level mechanisms remain incompletely resolved. In parallel, epitranscriptomics, an emerging field centered on chemical modifications to RNA, has revealed ...

RNF219 attenuates global mRNA decay through inhibition of CCR4-NOT complex-mediated deadenylation

Nature Communications, 2021
The CCR4-NOT complex is a key regulator of eukaryotic mRNA deadenylation. Here the authors identified the E3 ubiquitin ligase RNF219 as an acetylation-regulated cofactor of the complex, which inhibits mRNA decay through a direct interaction with NOT9.

Targeting the microbiota‐miRNA‐protease axis: A new therapeutic avenue in melanoma

The FEBS Journal, EarlyView.
Modulation of extracellular matrix (ECM) turnover is central to melanoma progression and metastasis, driven largely by ECM proteases. This review highlights the epigenetic regulation of ECM proteases by microRNAs and their roles in melanoma growth, invasion, and immune modulation.

SMG5-SMG7 authorize nonsense-mediated mRNA decay by enabling SMG6 endonucleolytic activity

Nature Communications, 2021
Degradation of nonsense mediated mRNA decay (NMD) substrates is carried out by two seemingly independent pathways, SMG6-mediated endonucleolytic cleavage and/or SMG5-SMG7-induced accelerated deadenylation.

OsFKBP20‐1b stabilizes OsUPF1 and OsUPF2 to promote the degradation of aberrant mRNAs during dehydration stress

Journal of Integrative Plant Biology, EarlyView.
The rice protein OsFKBP20‐1b protects key RNA‐surveillance factors from breakdown, so they can better eliminate defective messages. This RNA quality‐control boost reduces errors and helps plants survive drought, revealing a link between RNA control and drought tolerance.

Composition and function of P bodies in Arabidopsis thaliana

Frontiers in Plant Science, 2014
mRNA accumulation is tightly regulated by diverse molecular pathways. The identification and characterization of enzymes and regulatory proteins involved in controlling the fate of mRNA offers the possibility to broaden our understanding of ...

To translate, or not to translate: viral and host mRNA regulation by interferon-stimulated genes. [PDF]

, 2015
Type I interferon (IFN) is one of the first lines of cellular defense against viral pathogens. As a result of IFN signaling, a wide array of IFN-stimulated gene (ISG) products is upregulated to target different stages of the viral life cycle.
