Paper The nuclear concentration required for antisense oligonucleotide activity in myotonic dystrophy cell
Peptide PepFect14 (PF14)
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed yes
Label Confidence high
In Vitro Functional Effect no
Endosomal Escape Evidence yes
Peptide Concentration Matched to CAG5 condition at same ASO dose (e.g., 9× molar excess).
Rna Concentration Control ASO tested alongside CAG5 (e.g., 0.1–1.0 µM).
Mixing Ratio N/P = 3 (PF14), peptide:ASO molar ratio 9:1; stabilized ~1 h RT.
Formulation Format Noncovalent CPP/ASO polyplex (charge-driven nanoparticle)
Formulation Components PF14 + control steric-blocking ASO (GAC5) polyplex.
Size Nm
Zeta Mv
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells Immortalized human DM1 myoblasts (DM11 cl5) and unaffected myoblasts (C25); fibroblast validation in some experiments
Animal Model
Administration Route
Output Type in vitro negative control (splice correction)
Output Value No splice correction of DM1-associated mis-splicing compared with untreated DM1 cells.
Output Units
Output Notes Used as sequence control to confirm specificity of CAG5 activity.
Toxicity Notes Same PF14 dose-dependent viability trend applies; control used for interpretation.
