MiR‐940 Suppresses Ferroptosis by Controlling Expression of Key Regulatory Genes

Advanced Science, EarlyView.
A CRISPR‐based screening identified miR‐940 as a critical suppressor of ferroptosis in cancer. By coordinating the downregulation of pro‐ferroptotic genes with the upregulation of GPX4, miR‐940 establishes a regulatory network that protects against ferroptosis and correlates with poor clinical outcomes in distinct cancer entities.

Staufen Negatively Modulates MicroRNA Activity in Caenorhabditis elegans

G3: Genes, Genomes, Genetics, 2016
The double-stranded RNA-binding protein Staufen has been implicated in various posttranscriptional gene regulatory processes. Here, we demonstrate that the Caenorhabditis elegans homolog of Staufen, STAU-1, functionally interacts with microRNAs.

Nucleic Acid Therapeutics for “Undruggable” Cancer Targets: Mechanisms, Challenges, and Prospects

Advanced Science, EarlyView.
Nucleic acid therapeutics bypass the structural limitations of conventional drugs by targeting mRNA rather than proteins. This review examines how antisense oligonucleotides, siRNAs, miRNAs, aptamers, and mRNA vaccines intervene against historically undruggable oncoproteins including Ras, MYC, and p53, highlighting mechanistic advances, delivery ...

Functional non-coding RNAs derived from the flavivirus 3′ untranslated region

Virus Research, 2015
Flaviviruses are single-stranded positive sense RNA enveloped viruses. The flavivirus genus includes important human pathogens such as dengue virus (DENV), West Nile virus (WNV), yellow fever virus (YFV), Japanese encephalitis virus (JEV), tick-borne encephalitis virus (TBEV), and Murray Valley encephalitis virus (MVEV).

Engineered Exosomal miR‐146a‐5p Reprograms BMSC Fate and Restores Mitochondrial Homeostasis in Glucocorticoid‐Induced Osteonecrosis of Femoral Head

Advanced Science, EarlyView.
Exosomal miR‐146a‐5p is identified as a pivotal regulator in steroid‐induced osteonecrosis. Its reduction activates NF‐κB signaling, compromises mitophagy, and disrupts mitochondrial bioenergetics, resulting in autophagic disequilibrium. Engineered exosomes delivering miR‐146a‐5p reinstate mitochondrial function, augment oxidative phosphorylation and ...

Plus-strand RNA viruses hijack Musashi homolog 1 to shield viral RNA from cytoplasmic ribonuclease degradation

Journal of Virology
A successful strategy employed by RNA viruses to achieve replication is to evade host cell RNase degradation. However, the mechanisms through which plus-strand RNA viruses effectively shield viral RNA from cellular ribonuclease degradation remain unclear.

How to find RNA thermometers

Frontiers in Cellular and Infection Microbiology, 2014
Temperature is one of the decisive signals that a mammalian pathogen has entered its warm-blooded host. Among the many ways to register temperature changes, bacteria often use temperature-modulated structures in the untranslated region of mRNAs.

Epidermal METTL1‐Mediated m7G Modification Drives Psoriatic Inflammation by Stabilizing Bdkrb1 and Orchestrating Neutrophil Recruitment

Advanced Science, EarlyView.
This study unveils an unrecognized pro‐inflammatory epitranscriptomic checkpoint in psoriasis. By installing m7G modifications on the 5′ UTR of Bdkrb1 mRNA, METTL1 enhances receptor stability to orchestrate keratinocyte‐driven neutrophil recruitment via p38 MAPK signaling.

Cell morphogenesis proteins are translationally controlled through UTRs by the Ndr/LATS target Ssd1.

PLoS ONE, 2014
Eukaryotic cells control their growth and morphogenesis to maintain integrity and viability. Free-living cells are further challenged by their direct interaction with the environment and in many cases maintain a resilient cell wall to stay alive under ...
