Abstract
Tumor-targeted drug delivery via chemotherapy is very effective on cancer treatment. For potential anticancer agent such as Camptothecin (CPT), high chemotherapeutic efficacy and accurate tumor targeting are equally crucial. Inspired by special CD44 binding capability from hyaluronic acid (HA), in this study, novel HA-coated CPT nanocrystals were successfully prepared by an antisolvent precipitation method for tumor-targeted delivery of hydrophobic drug CPT. These HA-coated CPT nanocrystals demonstrated high drug loading efficiency, improved aqueous dispersion, prolonged circulation, and enhanced stability resulting from their nanoscaled sizes and hydrophilic HA layer. Moreover, as compared to crude CPT and naked CPT nanocrystals, HA-coated CPT nanocrystals displayed dramatically enhanced in vitro anticancer activity, apoptosis-inducing potency against CD44 overexpressed cancer cells, and lower toxic effect toward normal cells due to pH-responsive drug release behavior and specific HA-CD44 mediated endocytosis. Additionally, HA-coated CPT nanocrystals performed fairly better antimigration activity and biocompatibility. The possible molecular mechanism regarding this novel drug formulation might be linked to intrinsic mitochondria-mediated apoptosis by an increase of Bax to Bcl-2 ratio and upregulation of P53. Consequently, HA-coated CPT nanocrystals are expected to be an effective nanoplatform in drug delivery for cancer therapy.

Abstract
Chemotherapeutic drugs have a series of limitations in anti-tumor treatment, mainly including multidrug resistance (MDR) and serious adverse reactions. Co-delivery system with two or more synergistic therapeutic drugs is an effective strategy to settle these limitations. In this study, active tumor-targeted co-delivery micelles (DOX+Cur)-PMs, with two synergistic drugs of a therapeutic drug of doxorubicin (DOX) and a chemosensitizer of curcumin (Cur) co-encapsulated into hyaluronic acid-vitamin E succinate (HA-VES) graft copolymer, were prepared and delivered simultaneously into tumor cells for improving therapeutic effects of DOX. (DOX+Cur)-PMs had uniform particle size, high encapsulation efficacy, sustained release profile and good colloidal stability. In vitro cytotoxicity study, (DOX+Cur)-PMs exerted the strongest cytotoxicity and highest cell apoptosis-inducing activities against DOX-resistant MCF-7/Adr cells. Moreover, (DOX+Cur)-PMs more efficiently internalized into cancer cells and enhanced the cellular uptake of DOX via energy-dependent and caveolae-mediated endocytosis, and significantly reversed MDR effects via CD44 targeting delivery and the synergic effect of released Cur. More importantly, in vivo results illustrated that (DOX+Cur)-PMs not only displayed better tumor accumulation and tumor targeting, and more efficiently inhibited the growth of tumor in 4T1 tumor-bearing mice, but also induced significantly less pathological damage to the cardiac tissue in comparison with free DOX, even DOX-PMs and DOX-PMs+Cur. In summary, this targeted combinational micellar delivery system with DOX and Cur could be a promising vehicle in tumor therapy.

Abstract
Tumor-targeted delivery system has been developed as an attractive strategy for effective tumor therapy. In this study, in order to enhance the antitumor effects of doxorubicin (DOX), amphiphilic hyaluronic acid (HA)-conjugated vitamin E succinate (VES) copolymers (HA-VES) with different degrees of substitution (DS) were prepared with synergistic antitumor effects and active targeting activities, and utilized as nanocarriers for the efficient delivery of DOX. DOX-loaded HA-VES polymeric micelles (HA-VES/DOX) self-assembled from dual-functional HA-VES copolymer and exhibited excellent loading efficiency and superior colloidal stability. In vitro, HA-VES/DOX displayed enhanced cytotoxicity with synergistic anticancer effects of HA-VES copolymer, high apoptosis-inducing activities of tumor cells, and reversal effects of DOX on multidrug resistance, in comparison with DOX. Also, in vitro cellular uptake and subcellular localization studies revealed that HA-VES/DOX could more efficiently internalize into cancer cells and selectively release DOX within lysosomes, thereby enhancing the distribution of DOX in nuclei and facilitating its interactions with DNA. Specifically, HA-VES/DOX decreased the activity of CD44 mRNA and improved the targeting efficiency on MCF-7 cells, based on the active recognition between HA and CD44 receptor. More importantly, HA-VES/DOX displayed better tumor accumulation and targeting, and enhanced antitumor efficacy with reduced systemic toxicity in 4T1 tumor-bearing mice. In summary, the developed HA-VES-based drug delivery system, which increased drug targeting on the tumor site and exhibited preferable anticancer activity, could hold great potential as an effective and promising strategy for efficient tumor therapy.
