Pharmacologic Modulation of ARID3A with Rimegepant Reactivates Type I Interferon Signaling and Sensitizes Triple‐Negative Breast Cancer to PD‐1 Blockade

Advanced Science, EarlyView.
This study identifies ARID3A as a key immunosuppressive transcription factor in TNBC. Its inhibition activates the type I IFN pathway, boosting CD8+ T cell infiltration and sensitizing tumors to anti‐PD‐1. The FDA‐approved migraine drug Rimegepant targets ARID3A, enhances immunotherapy efficacy in preclinical models, and establishes a druggable axis to

Regulation of anti-CRISPR operons by structurally distinct families of Aca proteins

Communications Biology
CRISPR-Cas systems provide bacteria with adaptive immunity against bacteriophages and mobile genetic elements, driving an evolutionary arms race in which phages deploy anti-CRISPR (Acr) proteins.

Dose‐Dependent Reprogramming of Chromatin Accessibility by SOX4 Drives the Transcriptional Response to Iron Overload

Advanced Science, EarlyView.
This study demonstrates that iron overload triggers widespread chromatin compaction and transcriptional repression in human granulosa cells, recapitulating features of endometriosis. The epigenetic reprogramming is orchestrated by a TFEB‐SOX4‐SWI/SNF axis, with SOX4 acting as a central, dosage‐sensitive regulator.

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.

Costly intermediation and the big push [PDF]

Many existing theories of financial intermediation have difficulty explaining why financial activity can generate large real effects. This paper argues that the large real effects may reflect a multiplicity of equilibria.

In vivo structure profiling reveals human cytosolic and mitochondrial tRNA structurome and interactome in response to stress

Nature Communications
Transfer RNA (tRNA) is the most abundant cellular RNA family in terms of copy numbers. It not only folds into defined structures but also has complex cellular interaction networks involving aminoacyl-tRNA synthetases, translation factors, and ribosomes ...

Haplotype‐Resolved 3D Genomic Landscapes and Their Impacts on Agronomic Traits in Grapevine

Advanced Science, EarlyView.
This study presents a haplotype‐resolved 3D genomic landscape of grapevine, revealing that structural variations (SVs) are closely associated with phased topologically associating domain (TAD) boundary transitions. These rearrangements coordinate with allele‐specific DNA methylation (ASM) and allele‐biased gene expression (ASE) to shape key agronomic ...

Characterization of repression capability of Sin3-associated protein 30-like and its alternatively spliced isoforms [PDF]

, 2008
Background and Aims: Within the nucleus of eukaryotic cell, DNA is packaged with histone proteins to from nucleosomes that arrange further to form higher-order packaged structures. This three dimensional structure forms a physical barrier between DNA and

A Circuit of Mechanically Regulated Transcription Factors Balances Regenerative and Fibrotic Memory of Mesenchymal Stromal Cells

Advanced Science, EarlyView.
Producing MSCs on rigid culture substrates induces a scar‐making phenotype, jeapordizing therapeutic success. ‘Tissue‐soft’ surfaces prevent MSC fibrogenesis and preserve regenerative traits. An epigenetic network, driven by HOXA11 and SALL1, maintains ‘soft memory’ by keeping chromatin open in relaxed MSCs, promoting anti‐fibrotic programs.
