Effective Chemotherapy Of Lung Cancer Using Bovine Serum Albumin-Coated Hydroxyapatite Nanoparticles

Background: Successful chemotherapy of lung cancer relies largely on the use of a good drug delivery system (DDS). We successfully constructed a hybrid DOS comprised of hydroxyapatite (HAP) nanoparticles and bovine serum albumin (BSA).Material/Methods: The HAP nanoparticles were selected as the core to encapsulate the anticancer drug doxorubicin (DOX), followed by surface modification of BSA as a stabilizer and shielding corona to finally prepare the hybrid DDS (BSA/HAP/DOX).Results: The following characterizations revealed that BSA/HAP nanoparticles have high stability, high biocompatibility, and good DOX-loading capability to meet in vivo applications. Moreover, BSA/HAP/DOX can enhance the cellular uptake of drug in A549 cells (lung cancer cells). Most importantly, BSA/HAP had better in vivo tumor targetability than bare HAP nanoparticles, which resulted in stronger anticancer efficacy both in vitro and in vivo than free DOX or HAP/DOX, and greatly decreased the adverse effects of free DOX.Conclusions: Our hybrid DDS shows potential to be applied in more advanced application of cancer therapy.
