Peptide CC9
Delivery Success Class yes
In Vivo Flag yes
Uptake Confirmed yes
Label Confidence medium
In Vitro Functional Effect
Endosomal Escape Evidence
Peptide Concentration CC9 co-administered/combined with PC/miR-34a complexes (concentration not explicitly stated for in vivo; optimized at 20 µM for in vitro)
Rna Concentration miR-34a 15 µM in injection solution; 20 µg per dose (100 µL)
Mixing Ratio N/P = 30; CC9 added post-complexation
Formulation Format PC/miRNA polyplex with co-administered CC9 (physical combination) for systemic tumor therapy
Formulation Components PC/miR-34a polyplex (N/P 30) with free CC9 added (PC/miR-34a + CC9; CC9 20 µM used in vitro optimization) administered IV to PANC-1 xenograft mice
Size Nm 261.00
Zeta Mv 16.50
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); increased TUNEL-positive cells; tumor miR-34a upregulated; Bcl-2/cyclin D1 reduced
Output Units
Output Notes Tumor targeting and penetration attributed to CC9 (RGD motif + proteolytic cleavage to CRGDK with neuropilin-1 binding).
Toxicity Notes No major systemic toxicity described in the paper.
