Abstract
The main aim of this work was to evaluate a nanoconjugate system of paclitaxel loaded self-assembling, biodegradable micelles for targeting CD44 overexpression in cancer cells. The shape and size, zeta potential, encapsulation efficiency and cell uptake of these drug-loaded micelles were evaluated. To understand their bio distribution profile, the hyaluronate (HA) micelles were labeled with Flammaâ¢-774 NIR dye and injected into SCC7 tumor induced mice. Cell viability in response to drug loaded and unloaded micelles was studied in SCC7 cancer cells using the MTS assay. An in vivo tumor inhibition study was conducted by intravenous injection of paclitaxel-loaded HA micelle nanoparticles as well as control nanoparticles without paclitaxel. The shape of the nanomicelles was evaluated by loading them with hydrophobic superparamagnetic iron oxide nanoparticle and then visualizing them by TEM. In conclusion, paclitaxel-loaded HA nanoparticulate micelles might be found to be a specific and efficient chemotherapeutic treatment for CD44 overexpressing cancer cells.
