| Abstract | A biomimic reconstituted high-density-lipoprotein-based drug and p53 gene co-delivery system (rHDL/CD-PEI/p53 complexes) was fabricated as a targeted co-delivery nanovector of drug and gene for potential bladder cancer therapy. Here, CD-PEI was utilized to effectively condense the p53 plasmid, to incorporate the plasmid into rHDL, and to act as an antitumor drug to suppress tumor angiogenesis. The rHDL/CD-PEI/p53 complexes exhibited desirable and homogenous particle size, neutral surface charge, and low cytotoxicity in vitro. The results of confocal laser scanning microscopy and flow cytometry confirmed that SR-BI-targeted function induced specific cytoplasmic delivery and high gene transfection efficiency in MBT-2 murine bladder cells. In addition, rHDL/CD-PEI/p53 complexes co-delivering CD and p53 gene achieved synergistic angiogenesis suppression by more effectively downregulating the expression of vascular endothelial growth factor (VEGF) messenger RNA (mRNA) and protein via different pathways in vitro. In vivo investigation on C3H/He mice bearing MBT-2 tumor xenografts revealed that rHDL/CD-PEI/p53 complexes possessed strong antitumor activity. These findings suggested that rHDL/CD-PEI/p53 complexes could be an ideal tumor-targeting system for simultaneous transfer of drug and gene, which might be a new promising strategy for effective bladder cancer therapy. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
