Abstract

Layer-by-layer (LbL) technique was employed to modify the surface of doxorubicin (Dox)-loaded bovine serum albumin (BSA) nanoparticles using hyaluronic acid (HA) to enable targeted delivery, to overexpressed CD44, receptors in metastatic breast cancer cells. LbL technique offers a versatile approach to modify the surface of colloidal nanoparticles without any covalent modification. Dox-loaded BSA (Dox Ab) nanoparticles optimized for their size, zeta potential, and drug encapsulation efficiency were prepared by modified desolvation technique. The cellular uptake and cytotoxicity of the coated Dox Ab nanoparticles were analyzed in CD44 overexpressing breast cancer cell line MDA-MB-231. Nanoparticles with HA as the, final layer (Dox Ab HA) showed maximum cellular uptake in MDA-MB-231 owing to the CD44 receptor-mediated endocytosis and hence, exhibited more cytotoxicity as compared to free Dox. Further, luciferase-transfected MDA-MB-231 cells were used to induce tumor in BALB/c female nude mice to enable whole body tumor imaging. The mice were imaged before and after Dox treatment to visualize the tumor growth. The in vivo biodistribution of Dox Ab HA nanoparticles in nude mice showed maximum accumulation in tumor, and importantly, better tumor reduction in. comparison with free Dox, thus paving the way for improved drug delivery into tumors.
