CRISPR via nanocarriersHA liposome/protamine + Cas9-MTH1NSCLC (A549); liver metastasis micePreclinicalMTH1 knockout → reduced lung tumor + liver mets[82]
C14-PEG-PEI micelleplex (Cas9-KRAS G12S)KRAS-mutant NSCLC (A549)PreclinicalKRAS editing → cell death ↑, migration ↓[83]
Cryo-shocked tumor vesicle (Cas9-CDK4)KRAS-driven NSCLC micePreclinicalCDK4 knockout → regression + survival benefit[84]
Reformulated nano-chemotherapyInhalable liposome (osimertinib + IGF2BP3-plasmid)EGFR+ NSCLC + brain mets (mouse)PreclinicalDual lung/brain targeting → tumor & brain mets suppression[85]
