Peptide Concentration
Rna Concentration siRNA 1 mg/mL (topical application; 60 μL)
Mixing Ratio SHP/siRNA N/P = 10:1; siRNA concentration 1 mg/mL for topical dosing
Formulation Format pH-switchable cationic micelles (SHP) assembled from SCP-HA-PAE
Formulation Components SCP (ACTGSTQHQCG) + hyaluronic acid (HA, MW 8000) + poly(β-amino ester) (PAE)
Size Nm 170.00
Zeta Mv
Model Scope in_vivo
Model Type in vivo
Cell Lines Or Primary Cells
Animal Model C57BL/6 nude mice with subcutaneous B16F10 melanoma xenograft; topical treatment at tumor site
Administration Route topical (transdermal) daily; 60 μL of SHP/siRNA-survivin
Output Type tumor growth inhibition + in vivo gene silencing (IHC) / apoptosis (TUNEL)
Output Value tumor volume <200 mm^3 after 10 weeks; ~10-fold smaller vs controls; survivin down ~75%
Output Units
Output Notes Compared vs PBS, naked siRNA-survivin, and blank SHP; SHP/siRNA-survivin showed necrotic/apoptotic regions and strongest TUNEL signal.
Toxicity Notes No obvious organ damage on H&E (heart, liver, spleen, lung, kidney); no noted physiological complications.
