• MLKL Polymerization Drives Lysosomal Permeabilization

  2026-08-16

  The reference study identifies MLKL polymerization-induced lysosomal membrane permeabilization as a critical execution step in necroptosis. By linking MLKL assembly to lysosomal cathepsin B release and cell death, it expands mechanistic models of how regulated necrosis progresses beyond plasma-membrane disruption.

• PXR Activation, Liver Regeneration, and CYP Induction

  2026-08-15

  This rat study shows that pregnane X receptor activation can couple liver enlargement and regeneration with increased CYP3A1/2 and CYP2C6/11 metabolic activity. Its cocktail-probe and protein-expression design provides a useful framework for distinguishing anatomical liver recovery from functional drug-metabolizing capacity.
