| Abstract | The present study was conducted to investigate the efficacy and safety of ultrasound (US)mediated transfection of the type 2 recombinant adenoassociated virus (AAV) vectors encoding the enhanced green fluorescent protein (EGFP) gene (rAAV), polyethylenimine (PEI)/plasmid EGFPN1 (pDNA) or lipofectamine (L)/carboxyfluorescein (FAM)labeled small interfering RNA (siRNA) in the human ARPE19 retinal pigment epithelial (RPE) cell line, with or without the addition of SonoVue. Cultured RPE cells were exposed to US, with or without SonoVue under different conditions, including variation in the intensity and duration of treatment, and the dose of microbubbles. The effects of ultrasoundtargeted microbubble destruction (UTMD) on the structure of pDNA and the transfection ability of rAAV, PEI/pDNA and L/siRNA were also evaluated. Furthermore, the effect of UTMD on RPE cells was evaluated at 0 and 24 h following UTMD. USmediated transfection (USMT) significantly increased L/siRNA transfection efficiency, as measured by the transgene expression per cell and the percentage of transfected cells. UTMD significantly increased rAAV and PEI/pDNA transfer to RPE cells. UTMDmediated rAAV or PEI/pDNA delivery was more effective than USMTmediated delivery of siRNA. Evaluating cell viability at 24 h postUTMD provided more valuable information than immediate evaluation following UTMD. Furthermore, there was minimal cytotoxicity and minimal change to the structure of pDNA under the optimal parameters. UTMD/US may be of use in enhancing rAAV, PEI/pDNA and L/siRNA transgene expression of ARPE19 cells in vitro. Studies on the transfection of different nucleotides (such as pDNA and siRNA) and different types of vectors (chemical and biological) mediated by UTMD may provide useful information to guide future in vivo and transfection studies. |

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.
