Peptide CC9
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed yes
Label Confidence high
In Vitro Functional Effect yes
Endosomal Escape Evidence
Peptide Concentration Free CC9 20 µM (optimal in transfection assays)
Rna Concentration miR-34a 0.15 µM per well (6-well) for qRT-PCR; 0.15 µM FAM-siRNA for uptake assays
Mixing Ratio N/P = 30; CC9 = 20 µM (optimal) added post-complexation
Formulation Format PC/miRNA polyplex with co-administered CC9 (physical combination)
Formulation Components PC/miR-34a polyplex (N/P 30) with free CC9 added after complexation (optimal CC9 20 µM) (PC/miR-34a + CC9)
Size Nm 261.00
Zeta Mv 16.50
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells PANC-1 (pancreatic cancer) (primary in vitro efficacy); BxPC-3 also tested; 293T as normal control
Animal Model
Administration Route
Output Type In vitro functional effects: miR-34a upregulation (qRT-PCR), cell cycle arrest, apoptosis, migration inhibition, target gene downregulation
Output Value miR-34a expression substantially increased; apoptosis ~44% (Annexin V/PI) for PC/miR-34a+CC9; target gene mRNA/protein reduced (E2F3, Bcl-2, c-myc, cyclin D1)
Output Units
Output Notes Higher uptake vs PC alone (flow cytometry ~87.5% FAM-positive); competitive inhibition with free RGD reduced uptake for conjugate system.
Toxicity Notes Low cytotoxicity reported (MTT; supporting info).
