| In Vivo Flag | no |
| Uptake Confirmed | yes |
| Label Confidence | high |
| In Vitro Functional Effect | yes |
| 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. |
