| Abstract | Objective: Most primary human ovarian tumors and peritoneal implants, as well as tumor vascular endothelial cells, express the CD44 family of cell surface proteoglycans, the natural ligand for which is hyaluronic acid (HA). Paclitaxel (PTX) is an effective chemotherapeutic agent that is widely used for the treatment of several cancers, including ovarian cancer. This study aimed to develop a HA-based PTX-loaded nanoparticle system to improve the ovarian cancer therapeutic effects.Methods: PTX-loaded cationic nanostructured lipid nanoparticles (PTX-NLCs) were prepared. HA-PE was then coated onto the PTX-NLCs by electrostatic adsorption to form HA-PTX-NLCs. In vitro tumor cell inhibition efficiency was analyzed on SKOV3 human ovarian cancer cells (SKOV3 cells) and PTX-resistant SKOV3 cells (SKOV3/PTX cells). In vivo anticancer ability was evaluated with mice bearing SKOV3 ovarian cancer cells xenografts.Results: HA-PTX-NLCs had an average diameter of 163 nm, and PTX was incorporated with an efficiency of over 80%. The in vitro viability of SKOV3 cells and SKOV3/PTX cells was obviously inhibited by HA-PTX-NLCs. In the ovarian cancer cells model, significant reduction in tumor growth was observed, whereas the conventional PTX injection group did not achieve significance.Conclusion: This study demonstrated that significantly improved results were obtained by the newly constructed HA-PTX-NLCs, in terms of in vitro and in vivo therapeutic efficacy. These findings strongly support the superiority of HA based nano-system for the PTX delivery, thus enhance the efficacy of ovarian cancer chemotherapy. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
