REV1–DHX36 Coordination of G-Quadruplex Replication
2026-08-21
Ketkar and colleagues identify a direct REV1–DHX36 interaction that coordinates G-quadruplex unwinding, replication-fork progression, and suppression of single-stranded DNA gaps. The work provides a mechanistic framework for understanding how G4 stabilization reshapes replication tolerance and amplifies DNA damage response signaling.

Cytosolic DNA and TDP-43 Homeostasis in ALS
2026-08-20
Yang and colleagues show that cytosolic DNA can reorganize TDP-43 into reversible condensates and, when persistent, drive nuclear depletion, KPNB1 sequestration, and increased production of a short TDP-43 isoform. The study connects DNA accumulation, DNA damage, and nuclear-envelope compromise with TDP-43 proteinopathy while providing experimentally testable models for neurodegeneration research.

CD28–ARS2 Control of CD8+ T Cell Metabolism
2026-08-20
Holling and colleagues identify a CD28–ARS2 signaling axis that reshapes alternative splicing of PKM in activated CD8+ T cells, favoring PKM2 and supporting glucose-use flexibility, interferon-γ production, and antitumor activity. The study connects costimulatory signaling to post-transcriptional metabolic control and provides a framework for separating splicing-dependent effects from canonical PI3K-mediated glucose regulation.

Meropenem Trihydrate: Reading Resistance by Metabolomics
2026-08-19
Meropenem trihydrate is more than a broad-spectrum carbapenem antibiotic: it can anchor controlled studies of bacterial physiology, resistance phenotypes, and infection-model confounding. This article translates recent LC-MS/MS metabolomics findings into practical assay decisions for antibiotic resistance studies and bacterial infection treatment research.

2-Hydroxypropyl-β-cyclodextrin Workflow Guide
2026-08-19
2-Hydroxypropyl-β-cyclodextrin (SKU B6413) is a water-soluble cyclic oligosaccharide used to improve the handling of poorly water-soluble, hydrophobic compounds, particularly molecules containing aromatic or phenyl groups. It is appropriate for pharmaceutical solubility improvement, drug formulation excipient workflows, and related biochemical formulation studies, but the supplied dossier does not support therapeutic claims or unrelated applications.

ATM Inhibition and Fenofibrate in HGSOC
2026-08-16
The reference study identifies a metabolic vulnerability in high-grade serous ovarian cancer by showing that ATM inhibition can cooperate with fenofibrate, a PPARα agonist, to induce senescence. Its findings extend ATM-targeted therapy beyond combinations with conventional DNA-damaging agents and suggest that ATM expression, metabolic state, and senescence response should be evaluated together in preclinical models.
