• Targeted mRNA Nanoparticles After Ischemic Stroke

  2026-08-26

  Gao and colleagues developed mannose-targeted lipid nanoparticles carrying IL-10 mRNA to redirect microglial responses in ischemic brain tissue. In mouse stroke models, this strategy reduced neuroinflammation, improved blood–brain barrier integrity, limited neuronal apoptosis, and supported functional recovery, with therapeutic activity reported when treatment was initiated up to 72 hours after stroke.

• AMPK–SQSTM1 Feedback in Metabolic Stress

  2026-08-26

  Choi et al. identify a double-positive feedback loop in which SQSTM1/p62 and AMPK reinforce one another during metabolic stress, coordinating KEAP1 degradation, NFE2L2/NRF2 activation, and lysosomal AMPK signaling. The study connects lysosomal deacidification, PP2A-dependent transcriptional control, ROS-sensitive TAK1 activation, and SQSTM1 phosphorylation to explain how tumor cells sustain antioxidant defenses under nutrient limitation.

• Cell Counting Kit-8 for Osteoblast Viability

  2026-08-25

  Learn how cck8 chemistry can quantify osteoblast growth, senescence-related loss of viability, and treatment response in a practical 96-well workflow.

• BRCA2 Prevents PARP1 Retention and Protects RAD51 Filaments

  2026-08-25

  The 2025 Nature study identifies a direct mechanism linking BRCA2-dependent homologous recombination to PARP inhibitor activity: BRCA2 prevents PARP1 from remaining bound to resected DNA and thereby stabilizes RAD51 filaments. Biochemical reconstitution, single-molecule FRET, strand-exchange assays, and cellular localization microscopy together show how PARP1 retention can obstruct DNA repair in BRCA2-deficient settings.

• Biomimetic Nanotherapy for Metastatic TNBC

  2026-08-24

  The ACS Nano study developed a biomimetic mesoporous silica nanoplatform that combines photothermal tumor ablation with tumor vaccination and immune checkpoint modulation. Its significance lies in coordinating tumor targeting, stimulus-responsive cargo release, and immune remodeling to address recurrence and metastasis rather than treating the primary tumor alone.

• Losmapimod: Rethinking p38 MAPK Translation

  2026-08-24

  Losmapimod and its synonym GW856553X offer translational researchers a defined way to interrogate p38α/β signaling across inflammation, vascular biology, hypertension, and COPD research.
