Peptide CC9
Delivery Success Class yes
In Vivo Flag yes
Uptake Confirmed yes
Label Confidence high
In Vitro Functional Effect
Endosomal Escape Evidence
Peptide Concentration Peptide conjugated on polymer (PC-CC9-10% feed); no free peptide added
Rna Concentration miR-34a 15 µM in injection solution; 20 µg per dose (100 µL)
Mixing Ratio N/P = 30
Formulation Format PC-CC9/miRNA polyplex (covalent peptide-conjugated polymer) for systemic tumor therapy
Formulation Components PC-CC9 (PC-CC9-10% feed) complexed with miR-34a at N/P 30; administered IV to PANC-1 xenograft mice (treatment twice weekly for 2 weeks)
Size Nm 225.00
Zeta Mv 8.60
Model Scope in_vivo
Model Type in vivo
Cell Lines Or Primary Cells
Animal Model BALB/c athymic female mice bearing subcutaneous PANC-1 xenografts
Administration Route Intravenous injection (100 µL); twice per week for 2 weeks; dose miR-34a 20 µg per injection
Output Type In vivo antitumor efficacy and tumor apoptosis
Output Value Tumor growth strongly inhibited (tumor volumes <100 mm3 in treated groups); increased TUNEL-positive cells; miR-34a upregulated in tumor; Bcl-2/cyclin D1 reduced
Output Units
Output Notes Tumor targeting supported by increased tumor localization/fluorescence in tumor sections vs non-targeting PC; PET imaging shows reduced tumor signal/size.
Toxicity Notes No major systemic toxicity described in the paper (no detailed body-weight/toxicology focus).
