CD28–ARS2 Control of CD8+ T-Cell Metabolism
2026-08-27
A 2024 study identifies a CD28–ARS2 signaling axis that reshapes PKM alternative splicing and gives activated CD8+ T cells greater flexibility in glucose use. The findings connect exon selection, PKM2 expression, interferon-γ production, and antitumor activity through a mechanism that is distinct from canonical PI3K signaling.

ERAD Chimeras for Targeted Membrane Protein Degradation
2026-08-26
Song et al. establish ERAD-engaging chimeras (ERADECs), a small-molecule targeted protein degradation platform that recruits the ER E3 ligase SYVN1 to eliminate transmembrane proteins. The study demonstrates potent PD-L1 degradation, improved tumor suppression relative to a clinically used antibody in vivo, and broader utility through desonide-enabled degradation of mutant huntingtin.

Bismuth Subsalicylate in GI Cell Assays
2026-08-25
Bismuth Subsalicylate can anchor gastrointestinal disorder research when prostaglandin pathway modulation is paired with a direct membrane-injury readout. This workflow uses recombinant annexin V to separate early phosphatidylserine exposure from later loss of membrane integrity while addressing the compound’s water insolubility and suspension-driven variability.

SB-505124 Hydrochloride in Causal Biology
2026-08-25
SB-505124 hydrochloride provides a selective way to test whether ALK4/5/7 signaling contributes to fibrosis, mechanotransduction, or cancer-cell phenotypes. This article develops a causal assay framework that connects Smad2/3 signaling with the MRTFA–KCNMB1 stiffness axis without conflating correlation with mechanism.

PCMT1 and Ovarian Cancer Metastasis: CRISPR Study
2026-08-24
Zhang et al. used a genome-wide CRISPR/Cas9 knockout screen to identify PCMT1 as a driver of anoikis resistance and ovarian cancer dissemination. The study connects extracellular PCMT1 to LAMB3–integrin–FAK–Src signaling, providing a mechanistic explanation for enhanced adhesion, spheroid growth, invasion, ascites formation, and distant metastasis.

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.
