Development of a tumor cell type-selective and cancer gene-specific nanocomplex for ALCL cells. A, A nano-sized carrier core structure was initially formed via aggregation of polyethyleneimine (PEI) and crosslinking with sodium citrate (PEI-citrate nanocore). The synthetic RNA-based CD30 aptamers and ALK siRNA were then incorporated onto the PEI-citrate nanocore to form the nanocomplex. B, When the functional RNA nanocomplex is added to cultures, the aptamer component will selectively target CD30-positive ALCL cells. Aptamer-mediated cell binding will facilitate intracellular delivery of the nanocomplex. The siRNA component will subsequently silence the cellular ALK gene, resulting in the growth arrest of ALCL cells.
