Endosomal Escape Evidence
Peptide Concentration 6 µM
Rna Concentration 100 nM
Mixing Ratio MR 1/60 (siRNA/NP1; N/R≈60)
Formulation Format noncovalent NP1/siRNA complex (nanoparticle)
Formulation Components NP1 + HIF-1α siRNA (electrostatic complex)
Size Nm
Zeta Mv
Model Scope in_vitro
Model Type in vitro (3D spheroid)
Cell Lines Or Primary Cells HCT 116 3D tumour spheroids (hanging drop)
Animal Model
Administration Route
Output Type Phenotypic effect (Ki-67 IHC; apoptosis by Annexin V/PI FACS)
Output Value Reduced proliferation signal (Ki-67) and apoptosis observed after HIF siRNA treatment (qualitative)
Output Units
Output Notes NP1-HIF-siRNA treatment in 3D spheroids reduced Ki-67 proliferation staining and was associated with apoptosis responses (study reports induced apoptosis after HIF mRNA silencing).
Toxicity Notes NP1 peptide alone did not affect proliferation (Ki-67 staining similar to untreated); suggests low carrier toxicity under tested conditions.
