| 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. |
