β‐Elemene Rescues Radiation‐Induced Enteritis by Orchestrating a Host‐Microbiome Circuit That Fuels Epigenetic DNA Repair

Advanced Science, EarlyView.
This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.

SIRT7-dependent deacetylation of the U3-55k protein controls pre-rRNA processing

Nature Communications, 2016
SIRT7 is a protein deacetylase with important roles in rRNA synthesis, ribosome biogenesis and cell proliferation. Here the authors show a role of SIRT7 in rRNA maturation via deacetylation of U3-55k, a core component of the U3 snoRNP complex.

UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation

Advanced Science, EarlyView.
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.

Zebrafish models for dyskeratosis congenita reveal critical roles of p53 activation contributing to hematopoietic defects through RNA processing.

PLoS ONE, 2012
Dyskeratosis congenita (DC) is a rare bone marrow failure syndrome in which hematopoietic defects are the main cause of mortality. The most studied gene responsible for DC pathogenesis is DKC1 while mutations in several other genes encoding components of

Targeting Supramolecular Active Complexes of Nav1.7/Nav1.8 to Relieve Chronic Neuropathic Pain

Advanced Science, EarlyView.
In mice and patients with severe chronic neuropathic pain (NP), Nav1.7, Nav1.8, TrkB, and five cytoskeletal proteins form supramolecular active complexes (SMACs) with polygonal lattice structures as noxious signal amplifiers in dorsal root ganglion (DRG) neurons.

Tetrahymena ribozyme disrupts rRNA processing in yeast.

Journal of Biological Chemistry, 1994
The intervening sequence (IVS) of Tetrahymena thermophila nucleolar DNA interrupts a highly conserved sequence in the RNA core structure of the large ribosomal subunit. This location in nuclear DNA is unusual as most group I introns are in mitochondrial and chloroplast DNA.

Bifidobacterium Pseudolongum‐Derived Inosine Mitigates Polystyrene Nanoplastics‐Induced Hepatic Injury by Inhibiting the Polarization of M1 Macrophages

Advanced Science, EarlyView.
Probiotic B.p colonization elevated gut‐derived inosine level in the liver, while elevated inosine activated A2AR and subsequently blocked NPs‐induced polarization of M1 macrophages by repressing the miR155/SOCS1/NF‐κB pathway. This reduced the release of inflammatory cytokines and thereby, mitigated NPs‐induced hepatic injury.
