APEX-RNA-MS Maps RNA Modifications in Condensates
2026-08-24
Seo, Dhingani, and Kleiner introduce APEX-RNA-MS, a workflow that combines APEX2 proximity labeling with modified-nucleoside LC-MS to profile RNA modifications in defined protein neighborhoods. The study links m6A and m5C with DNA damage foci and shows that modified tRNAs accumulate near G3BP1 in arsenite-induced stress granules, providing a spatially resolved view of RNA regulation.

Fenofibrate, PPARα-YAP Signaling, and Liver Aging
2026-08-23
The reference study shows that fenofibrate-induced liver enlargement and activation of the PPARα-YAP signaling pathway are preserved across several aging mouse models. Its main contribution is demonstrating that hepatocyte enlargement, proliferation, and pathway activation remain broadly comparable with adult mice, providing a mechanistic basis for studying PPARα responses in older animals.

Patient-Derived 3D Spheroids in Prostate Cancer
2026-08-22
Linxweiler and colleagues developed viable three-dimensional spheroid cultures directly from radical prostatectomy specimens, addressing the shortage of representative models for organ-confined prostate cancer. The cultures retained key epithelial and prostate cancer markers, could be cryopreserved, and showed differential responses to androgen receptor-directed drugs, supporting their use in translational prostate cancer research.

Prostaglandin E2: Receptor Biology and Workflows
2026-08-21
Prostaglandin E2 (PGE2) is an endogenous lipid-derived autacoid that signals through four EP GPCR subtypes. Its receptor profile, handling requirements, and context-dependent immune effects make it useful for inflammation research, gastrointestinal mucosal protection, and reproductive medicine applications.

Artesunate Workflows for Cancer Response Studies
2026-08-20
Artesunate supports more than a single viability readout: it enables time-resolved studies of growth inhibition, cell killing, ferroptosis, and AKT/mTOR-associated responses. This workflow translates those properties into practical designs for small cell lung carcinoma research and esophageal squamous cell carcinoma models.

Alcohol, Anti-HIV Drugs, and Aging Liver Stress
2026-08-20
Chen and colleagues show that hepatocyte senescence and organismal aging amplify cellular stress and liver injury associated with alcohol, ritonavir, lopinavir, and hippuric acid. By combining senescent HepG2 and AML-12 cells with young and aged mouse models, the study identifies stress-response and metabolic changes that help explain increased liver vulnerability in older people with HIV and substance use disorders.

OTULIN–LUBAC Uncoupling in Childhood Pyoderma Gangrenosum
2026-08-19
This Nature Immunology study identifies homozygous OTULIN-R57C as a genetic cause of isolated, pediatric-onset pyoderma gangrenosum. Its key mechanistic insight is that OTULIN can remain catalytically active while losing its ability to bind LUBAC, linking dysregulated linear ubiquitination to myeloid IL-1β production and TNF-dependent death of skin-resident cells.

Adipose-Neural Signaling in Cardiac Arrhythmia
2026-08-19
Fan et al. developed a stem cell-based coculture model showing how epicardial adipose tissue can communicate with sympathetic neurons and cardiomyocytes through a leptin–NPY–Y1R pathway. The study links this axis to NCX and CaMKII activity, provides mechanistic evidence for arrhythmogenesis, and identifies measurable adipose-neural changes in patients with atrial fibrillation.

Danazol: From Steroid Mechanism to Translational Strategy
2026-08-18
Danazol is more than a historical endocrine agent: it is a mechanistically informative probe for steroidogenesis, luteinizing hormone regulation, androgen receptor signaling, and hypothalamic–pituitary–gonadal axis biology. This thought-leadership review connects Danazol and Danocrine research to a recent rat model of precocious puberty, practical experimental design, prostate cancer research, and strategic translational decision-making.
