Peptide Penetratin-derived CPP
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed yes
Label Confidence high
In Vitro Functional Effect yes
Endosomal Escape Evidence
Peptide Concentration
Rna Concentration 100 nM final siRNA (c-Myc or NC) for gene silencing assays
Mixing Ratio CPP–siRNA encapsulated in N-NB (surface PEGylation: DSPE-PEG2000 (10 molar, total PEGylated lipid 10)); DPPC/DSPC/PEGylated lipid = 90/10/10 (molar ratio); perfluorobutane (C3F8) gas core
Formulation Format CPP–siRNA/N-NB (+US)
Formulation Components CPP–siRNA conjugate (disulfide-linked; reducible by cytosolic GSH) encapsulated in non-targeted nanobubbles (no YSA ligand)
Size Nm 196.00
Zeta Mv
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells MCF-7 (human breast adenocarcinoma; EphA2-positive)
Animal Model
Administration Route
Output Type In vitro functional effect: c-Myc mRNA/protein reduction with ultrasound-triggered release
Output Value
Output Units
Output Notes Ultrasound increased CPP–siRNA delivery and gene silencing vs non-ultrasound conditions; weaker than YSA-NB (+US).
Toxicity Notes Blank NBs and ultrasound had minimal effect on MCF-7 viability (supplementary).
