UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation

Advanced Science, Volume 13, Issue 48, 28 August 2026.
ABSTRACT Flavivirus subgenomic RNAs (sfRNAs) antagonise antiviral defences, yet how sfRNAs are organized and maintained in cells remains poorly understood. Here we identify ubiquitin C‐terminal hydrolase L3 (UCHL3) as a post‐translational regulator of flavivirus sfRNA stability and function.

The decapping activator Edc3 and the Q/N-rich domain of Lsm4 function together to enhance mRNA stability and alter mRNA decay pathway dependence in Saccharomyces cerevisiae

Biology Open, 2016
The rate and regulation of mRNA decay are major elements in the proper control of gene expression. Edc3 and Lsm4 are two decapping activator proteins that have previously been shown to function in the assembly of RNA granules termed P bodies.

Deep Learning‐Based Multimodal Fusion of Whole‐Slide Images and RNA Sequencing Identifies Survival‐Relevant Glioblastoma Clusters

Cancer Medicine, Volume 15, Issue 8, August 2026.
ABSTRACT Glioblastoma is profoundly heterogeneous, and single‐modality analyses often miss prognostically relevant structure. We introduce a transparent, end‐to‐end workflow that fuses available whole‐slide histology and RNA‐seq to discover clinically meaningful glioblastoma subgroups using an unsupervised learning model after feature extraction ...

Stress‐Induced Switch in Small Extracellular Vesicle Secretion: From Constitutive ‘Torn Bag Mechanism’ to Exocytosis

Journal of Extracellular Vesicles, Volume 15, Issue 8, August 2026.
Stress‐induced switch. Under stress conditions, small extracellular vesicle release shifts from the constitutive ‘torn bag mechanism’ to exocytosis of multivesicular endosomes. https://BioRender.com/xn1pa1e. ABSTRACT The biogenesis of small extracellular vesicles (sEVs) is only partially understood.

The GSK3/SHAGGY‐like OsGSK3 phosphorylates and inhibits phase separation of OsFCA at Ser‐43 and Ser‐45 to regulate brassinosteroid signaling and rice architecture

New Phytologist, Volume 251, Issue 4, Page 1909-1929, August 2026.
A working model for GLYCOGEN SYNTHASE KINASE 3‐mediated phosphorylation of FLOWERING CONTROL LOCUS A in the regulation of brassinosteroid signaling and rice growth and development. Summary Brassinosteroid (BR) signaling plays a critical role in rice (Oryza sativa L.) grain development.

Long‐Term Salt Exposure Reprograms the Nicotiana tabacum BY‐2 Suspension Proteome and Metabolome Toward Stabilization of the Core Metabolic Pathways, Protein Turnover Machinery Modifications, and Protective Metabolome Adjustments

Plant, Cell &Environment, Volume 49, Issue 8, Page 5849-5865, August 2026.
ABSTRACT In this study, we analyzed a unique Nicotiana tabacum BY‐2 line that was gradually adapted to and subsequently maintained in 190 mM NaCl for over 15 years. Years of continuous high salinity shaped a stable “new homeostasis” in BY‐2 suspension cells. Salt‐adapted cells were smaller and formed tighter clusters. Metabolomics revealed constitutive

Investigating the regulation of the human decapping enzyme Dcp2 [PDF]

, 2012
.Decapping is a critical step in several mRNA decay pathways that are important for the regulation of gene expression. A major decapping complex consists of the decapping enzyme Dcp2 as well as several decapping enhancers.

Targeting Poxvirus Decapping Enzymes and mRNA Decay to Generate an Effective Oncolytic Virus

Molecular Therapy: Oncolytics, 2018
Through the action of two virus-encoded decapping enzymes (D9 and D10) that remove protective caps from mRNA 5′-termini, Vaccinia virus (VACV) accelerates mRNA decay and limits activation of host defenses.

The role of transcriptional ‘futile cycles’ in autophagy and microbial pathogenesis

Microbial Cell, 2015
Eukaryotic cells utilize macroautophagy (hereafter autophagy) to recycle cellular materials during nutrient stress. Target of rapamycin (Tor) is a central regulator of this process, acting by post-translational mechanisms, phosphorylating ...
