Paper Amphiphilic lipopeptide significantly enhances uptake of charge-neutral splice switching morpholino
Peptide Myr-ApoE (peptide amphiphile)
Delivery Success Class no
In Vivo Flag no
Uptake Confirmed no
Label Confidence high
In Vitro Functional Effect yes
Endosomal Escape Evidence
Peptide Concentration ~0.5 µM (as lipopeptide–PMO conjugate) + GMO 8 µg/mL
Rna Concentration ~0.5 µM (PMO equivalent)
Mixing Ratio
Formulation Format cubosome formulation (GMO)
Formulation Components GMO (monoolein) + Pluronic F108 + Myr-ApoE-PMO
Size Nm
Zeta Mv
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells SMA Type I patient-derived fibroblasts (GM03813)
Animal Model
Administration Route
Output Type splice-switching activity (RT-PCR; % full-length SMN2 transcript)
Output Value No significant improvement vs Myr-ApoE-PMO alone
Output Units
Output Notes Cubic phase structure of GMO disrupted by PA-PMO (SAXS); possible tight incorporation into GMO bilayer reduces release.
Toxicity Notes GMO reduced viability above 10 µg/mL; 8 µg/mL used for functional testing.
