METTL3–COL5A2 Axis Suppresses Ferroptosis in Gastric Cancer
2026-09-26
This study links METTL3-dependent m6A modification to stabilization of COL5A2 by IGF2BP3, connecting RNA regulation with FAK/MAPK/ERK signaling and reduced ferroptosis in gastric cancer models. Its combination of cell-based perturbations and xenograft evidence makes the pathway a useful framework for investigating how tumor cells resist ferroptotic stress, while leaving clinical relevance and pathway specificity to be tested.

SIRT1–PGC-1α–TFAM Signaling in Prion-Stressed N2a Cells
2026-09-25
Zhao et al. report that prion peptide exposure impairs SIRT1 activity and mitochondrial biogenesis in N2a cells, while SIRT1 overexpression or pharmacological activation alleviates mitochondrial damage and apoptosis. The study connects these effects to PGC-1α–TFAM signaling and positions Resveratrol as a useful experimental probe of this pathway, while leaving in vivo efficacy and clinical relevance unresolved.

Psoralen-Induced Cholestasis Through ERK1/2 Activation
2026-09-25
A 2024 zebrafish study found that the estrogen-like natural products psoralen and isopsoralen induce cholestatic liver injury alongside increased ERK1/2 phosphorylation and altered bile-acid regulation. Pharmacological rescue with an ERK1/2 antagonist supports ERK signaling as a mechanistically relevant node, while leaving questions about causality and transfer to human disease for future work.

Glucagon Cross-Talk at the GLP-1 Receptor
2026-09-24
Chepurny and colleagues used FRET-based cAMP assays, pharmacological antagonism, and molecular modeling to show that glucagon can activate the GLP-1 receptor as well as its canonical receptor. The findings caution against assuming ligand selectivity in metabolic experiments and offer a framework for testing receptor attribution in GLP-1 receptor signaling research.

SOD-Enabled Amplex Red Assays for NADPH Systems
2026-09-21
Mishina and colleagues showed that NADPH and NADH can create a superoxide-dependent interference in the Amplex Red/horseradish peroxidase assay, obscuring hydrogen peroxide production by microsomal enzymes. Their key methodological advance is the inclusion of superoxide dismutase, which enables continuous and more reliable H2O2 measurements in NAD(P)H-supported reactions.
