Chemo-biologic combinatorial drug delivery using folate receptor-targeted dendrimer nanoparticles for lung cancer treatment.

ABSTRACT: Co-administration of functionally distinct anti-cancer agents has emerged as an efficient strategy in lung cancer treatment. However, a specially designed drug delivery system is required to co-encapsulate functionally different agents, such as a combination of siRNA and chemotherapy, for targeted delivery. We developed a folic acid (FA)-conjugated polyamidoamine dendrimer (Den)-based nanoparticle (NP) system for co-delivery of siRNA against HuR mRNA (HuR siRNA) and cis-diamine platinum (CDDP) to folate receptor-α (FRA) -overexpressing H1299 lung cancer cells. The co-delivery of HuR siRNA and CDDP using the FRA-targeted NP had a significantly greater therapeutic effect than did individual therapeutics. Further, the FRA-targeted NP exhibited improved cytotoxicity compared to non-targeted NP
