• Dabigatran: From Thrombin Mechanism to Translation

  2026-08-13

  Dabigatran is more than a potent direct thrombin inhibitor: it is a translational tool for connecting molecular thrombin biology with plasma coagulation, therapeutic strategy, and assay design. This article outlines how to use Dabigatran and its metabolite benchmarks rigorously while avoiding common errors involving formulation, species translation, renal function, and clinical-to-laboratory extrapolation.

• SAN-Plexus Assembloids Model Pacemaker Maturation

  2026-08-13

  This study introduces human pluripotent stem cell-derived SAN-plexus assembloids that combine sinoatrial node, cardiac ganglionated plexus, and atrial-like organoids to model neuro-pacemaker development. By integrating electrophysiology with human SAN spatial transcriptomics, the authors identify a CGPO-derived prosaposin–GPR37 signaling axis that promotes pacemaker maturation and provides a framework for studying conduction dysfunction.

• Mitochondrial Calcium Signaling and Ferroptosis

  2026-08-12

  The reference study links mitochondrial calcium uptake through MCU to ferroptosis control by sustaining acetyl-CoA-dependent acetylation and activity of GPX4. Genetic, antioxidant-rescue, structural, and tumor-model experiments identify a mechanistic connection between mitochondrial metabolism, GPX4 regulation, and cancer-cell survival.
