Mixing Ratio encapsulation into liposome (not free peptide/siRNA complex)
Formulation Format enzyme-sensitive, TAT and cetuximab functionalized immunoliposome
Formulation Components DOTAP, DOPE, PC, cholesterol, DSPE-PEG(2000)-TAT, MAL-PEG(3000)-MMP2-DOPE, cetuximab
Size Nm 157.90
Zeta Mv 28.90
Model Scope in_vitro
Model Type in vitro
Cell Lines Or Primary Cells MCF7-MX (mitoxantrone-resistant breast cancer cells); MCF7 used for expression comparisons
Animal Model
Administration Route cell culture treatment with siRNA-loaded liposomes; uptake by flow cytometry (DiI) and functional assays at 24–48 h
Output Type gene silencing, chemosensitization
Output Value BCRP mRNA ~0.24-fold; BCRP protein ~0.2-fold at 48 h; mitoxantrone IC50 reduced ~4-fold with TAT+Cetuximab+
Output Units
Output Notes Flow cytometry shows increased uptake for TAT+Cetuximab+ vs controls; qPCR + western blot confirm BCRP knockdown; chemosensitization to mitoxantrone.
Toxicity Notes Nanoparticle IC10/IC50 reported; targeted formulations more cytotoxic; used IC10 for silencing assays.
