Rapid Purification of Recombinant Annexin V
2026-08-29
Burger and colleagues introduced a short purification strategy for recombinant annexin V that combines mild osmotic opening of Escherichia coli with reversible calcium-dependent capture on liposomes and final ion-exchange chromatography. The resulting analytical purity was designed to support demanding biophysical experiments, including crystallography, electron microscopy, spectroscopy, and single-channel measurements.

Leucovorin Calcium in Gastric Cancer Assembloids
2026-08-28
Leucovorin Calcium, also known as calcium folinate, offers translational researchers a mechanistically grounded way to study methotrexate rescue within patient-derived gastric cancer assembloids. By combining folate pathway perturbation with matched tumor and stromal models, researchers can move beyond simple viability readouts toward more informative analyses of microenvironment-dependent response and antifolate resistance.

IDO1 Blockade and Tumor-Protective JAK2/STAT3 Signaling
2026-08-26
The reference study shows that pharmacological IDO1 inhibition can activate antitumor immune cells while simultaneously inducing an IL-6–JAK2–STAT3 survival program within tumor cells. Its single-cell analysis supports combining IDO1 blockade with pathway-directed intervention, while also highlighting the limits of interpreting immune activation without resolving tumor-intrinsic responses.

How p38α Conformation Controls Dephosphorylation
2026-08-21
The preprint Dual-Action Kinase Inhibitors Influence p38α MAP Kinase Dephosphorylation shows that selected inhibitors can both suppress p38α catalytic activity and accelerate removal of its activation-loop phosphate by WIP1. Its biochemical and X-ray structural analyses provide a framework for designing kinase inhibitors that control phosphatase access, although the findings remain primarily mechanistic and preclinical.
