Paper Dual stimulus of hyperthermia and intracellular redox environment triggered release of siRNA for tum
Peptide CPP (penetratin-derived)
Delivery Success Class yes
In Vivo Flag yes
Uptake Confirmed no
Label Confidence medium
In Vitro Functional Effect
Endosomal Escape Evidence
Peptide Concentration
Rna Concentration Dose: 1.2 mg/kg siRNA (as siRNA-CPPs/TSL formulations)
Mixing Ratio
Formulation Format Thermosensitive liposome (TSL) encapsulating siRNA-CPP conjugate; heat-triggered release
Formulation Components DPPC:MSPC:DSPE-PEG2000 (87:3:10, w/w); encapsulated siRNA-CPP conjugate; hyperthermia 42°C 30 min (in vivo experiments); intracellular GSH reduces disulfide
Size Nm 88.49
Zeta Mv -22.30
Model Scope in_vivo
Model Type in vivo
Cell Lines Or Primary Cells
Animal Model Female BALB/c nude mice; HT-1080 xenograft
Administration Route IV (tail vein) + hyperthermia 42°C 30 min
Output Type Tumor growth inhibition; in vivo c-myc knockdown; biodistribution imaging
Output Value Tumor growth inhibition and in vivo gene silencing under hyperthermia (less than NGR-TSL)
Output Units
Output Notes Hyperthermia increased tumor accumulation even without NGR; TSL group showed lower gene silencing than NGR-TSL but better than several controls.
Toxicity Notes No pronounced body weight loss reported for liposomal groups
Curation Notes
