ATM–Fenofibrate Synergy in Ovarian Cancer Cells
2026-08-14
The reference study identifies a metabolic vulnerability in high-grade serous ovarian cancer by showing that pharmacologic ATM inhibition synergizes with fenofibrate, a PPARα agonist, in HGSOC cell models. Its findings extend ATM-targeted research beyond conventional DNA-damaging combinations and suggest that induced cellular senescence may be especially relevant in HR-proficient disease.

TSPAN18–STIM1 Axis in Prostate Cancer Bone Metastasis
2026-08-13
Zhou et al. identify TSPAN18 as a binding partner that stabilizes STIM1 by opposing TRIM32-mediated ubiquitination, thereby enhancing store-operated Ca2+ entry and prostate cancer bone-metastatic behavior. The work provides a mechanistic framework for connecting protein turnover, calcium signaling, tumor-cell motility, and clinical metastatic risk.

Topotecan HCl: Mechanism, Evidence, and Workflow
2026-08-12
Topotecan HCl is a semisynthetic camptothecin analogue and topoisomerase 1 inhibitor that stabilizes the topoisomerase I-DNA complex. Preclinical evidence supports DNA damage and apoptosis induction in rapidly dividing tumor cells, while product-specific concentration, solubility, and storage parameters define practical assay design.

Tomivosertib Calms Human DRG Hyperexcitability
2026-08-12
The reference study provides direct ex vivo evidence that MNK inhibition with tomivosertib rapidly and reversibly suppresses spontaneous activity in dorsal root ganglion neurons obtained from patients with radiculopathy. By linking electrophysiological changes to loss of eIF4E Ser209 phosphorylation, the work connects a defined signaling pathway with ectopic activity in human sensory neurons while also clarifying the limits of translating ex vivo findings into clinical treatment.

TSPAN18–STIM1 Signaling in Prostate Cancer Bone Metastasis
2026-08-09
Zhou et al. identify TSPAN18 as a regulator of STIM1 stability and show that it promotes prostate cancer bone metastasis by preventing TRIM32-mediated ubiquitination of STIM1. The study connects a protein-stability mechanism with store-operated calcium entry, cancer-cell invasion, and clinical metastatic risk, providing a framework for investigating the TSPAN18–STIM1 axis in prostate cancer research.

Norovirus Co-opts NINJ1 for Selective NS1 Secretion
2026-08-08
Song and colleagues show that murine norovirus exploits the membrane-rupture factor NINJ1 to release the viral protein NS1 through a regulated, cargo-selective pathway. The study combines genetic screening, cell biology, protein mutagenesis, and mouse infection models to connect caspase-3 activation, NINJ1 oligomerization, and suppression of intestinal antiviral immunity.
