Paper Development of an Efficient Transdermal Delivery System of Small Interfering RNA Using Functional Pe
Peptide AT1002 analog (AT-1002)
Delivery Success Class no
In Vivo Flag yes
Uptake Confirmed yes
Label Confidence high
In Vitro Functional Effect
Endosomal Escape Evidence
Peptide Concentration AT1002 400 µg per application (25 µL)
Rna Concentration 5 µg fluorescent siRNA per application; 10 h
Mixing Ratio siRNA + AT1002 (siRNA 5 µg + AT1002 400 µg) mixed (no N/P)
Formulation Format Topical siRNA + AT1002 (tight junction modulator) for transdermal delivery
Formulation Components FAMsiRNA or Cy3-siGL3 mixed with AT1002 and applied topically to tape-stripped mouse skin
Size Nm
Zeta Mv
Model Scope in_vivo
Model Type in vivo
Cell Lines Or Primary Cells
Animal Model ICR mice (male, 6-week); back skin tape-stripped; topical 10 h
Administration Route Topical application to tape-stripped dorsal skin (25 µL); confocal imaging
Output Type In vivo uptake/distribution in skin (confocal microscopy)
Output Value AT1002 drives more uniform surface distribution and deeper signal up to ~20 µm depth vs Tat alone
Output Units
Output Notes AT1002 disrupts ZO-1 staining (tight junction modulation) and effect is reversible after washing.
