Intravesical p21 mRNA-LNP Therapy in Bladder Cancer
2026-08-23
This 2026 FASEB Journal study developed chemically modified p21 mRNA encapsulated in lipid nanoparticles for localized intravesical treatment of bladder cancer. The formulation restored nuclear p21, altered cell-cycle and DNA-damage markers, suppressed orthotopic tumor growth, and produced strong bladder-localized expression with limited systemic distribution in mice.

Macrophage TIPE2 Drives ASC Ferroptosis in Obesity
2026-08-22
This Nature Communications study identifies a macrophage–adipose stem cell circuit that links obesity-associated inflammation to ferroptotic loss of adipose stem cells and visceral fat dysfunction. Its central mechanistic insight is that macrophage TIPE2 preserves exosomal ferritin delivery by restraining the IP3R–Ca2+–Drp1 mitochondrial fission axis, suggesting a cellular route for restoring adipose tissue homeostasis.
