Multianimal MRI for Pancreatic Tumor Monitoring
2026-09-20
Kempinska and colleagues introduce a four-chamber MRI workflow that images up to four KPC mice in one high-resolution acquisition, addressing the time and cost barriers of longitudinal pancreatic tumor measurement. The protocol also demonstrates how standardized MRI can support treatment-response studies, using gemcitabine as a proof-of-concept therapy in a clinically relevant pancreatic ductal adenocarcinoma model.

TECPR1 Tubulation Repairs Lysosomes During Energy Crisis
2026-09-17
This 2026 Cell Research study identifies TECPR1 as a lysosomal membrane-repair factor that recruits KIF1A to generate tubules from damaged, PI4P-enriched lysosomes. The findings connect membrane tubulation with lipid metabolism, survival during glucose starvation, and protection from liver injury in a metabolic-associated fatty liver disease model.

Adipose-Neural Axis in Cardiac Arrhythmia
2026-09-17
Fan et al. developed a stem cell-based coculture model showing how epicardial adipose tissue-derived leptin activates sympathetic neurons, increases neuropeptide Y release, and promotes cardiomyocyte arrhythmia through Y1R, NCX, and CaMKII signaling. The study connects EAT biology with neural and calcium-handling mechanisms while providing a framework for testing receptor- and pathway-specific interventions.

Anagliptin Vasorelaxation: Kv Channels and SERCA
2026-09-16
A 2025 Acta Diabetologica study found that Anagliptin relaxes phenylephrine-contracted rabbit aortic rings through pharmacologically defined involvement of voltage-dependent K⁺ channels and the SERCA pump. The findings separate this vascular response from endothelium-dependent signaling and canonical cAMP/PKA or cGMP/PKG pathways, providing a focused framework for diabetes-related vasorelaxant mechanism research.

Açaí Extracts: Hepatocyte Cytotoxicity and Induction
2026-09-16
This study combines consumer-relevant açaí preparations with human hepatocyte cytotoxicity and drug-metabolism assays to distinguish loss of viability from enzyme or transporter induction. Select extracts reduced hepatocyte viability in a dose- and time-dependent manner, whereas meaningful induction of major CYP enzymes and transporters was not detected, refining assessment of botanical-drug interaction risk.

ATRX-Deficient Glioma and RTK Inhibitor Sensitivity
2026-09-15
The reference study identifies a pharmacological vulnerability in ATRX-deficient high-grade glioma cells: increased sensitivity to multi-targeted receptor tyrosine kinase and selected PDGFR inhibitors. Its findings also support evaluating RTK inhibitor and temozolomide combinations while incorporating ATRX status into the interpretation of glioma drug studies.

N-MYC–eIF4G1 Signaling in inv(16) AML
2026-09-15
Peramangalam et al. identify an N-MYC–eIF4G1 survival pathway that helps maintain inv(16) acute myeloid leukemia. Their combination of transcriptomic analysis, enhancer investigation, primary leukemia models, and patient-derived xenografts provides a mechanistic framework for studying how CBFβ-SMMHC-associated transcriptional dysregulation supports leukemic survival.
