Administration Route
Output Type splice correction / mRNA knockdown
Output Value PF14 achieved ~37–59% AR-V7 mRNA reduction; others minimal
Output Units
Output Notes PF14 showed highest uptake, partial nuclear localization, and significant AR-V7 knockdown with reduced androgen-independent proliferation; hLF, L-R9, D-r9 showed uptake but no functional splice correction.
Toxicity Notes PF14 showed moderate carrier-associated toxicity at longer incubation; others minimal
