| Abstract | Hepatic fibrosis is a common form of wound healing in response to chronic liver injuries and can lead to more serious complications, including mortality. It is wellestablished that hepatic stellate cells (HSCs) are central mediators of hepatic fibrosis, and matrix metalloproteinase2 (MMP2) is important in the formation of liver fibrosis. In addition, HSCs are the primary cells secreting MMP2 and extracellular matrix, therefore, there has been increasing interest in developing agents with high selectivity towards HSCs. However, no clinical drugs based on MMP2, directed against HSCs, have been used to prevent fibrosis. Following consideration of the abundant vitamin A (VitA) receptors expressed on the cellular membrane of HSCs, the present study constructed VitAcoupled liposomes (VitAlips) using dicyclohexylcarbodiimide1, 3diaminopentane condensation, rotatory film processing and ultrasonic oscillation. The results revealed that the liposomes exhibited low cytotoxicity and a suitable binding ability to MMP2 small interference (si)RNA. Furthermore, the liposomes effectively delivered MMP2 siRNA to the HSCT6 cells. When HSCs were treated with the liposomes carrying MMP2 siRNA (VitAlipMMP2 siRNA), the mRNA expression and activity of MMP2, and the protein expression levels of smooth muscle actin and type I collagen were significantly reduced. These results suggested that inhibition of the expression of MMP2 in HSCT6 cells may contribute to preventing hepatic fibrosis, and provided experimental support to the development of specific drugs against MMP2 to prevent fibrogenesis in chronic liver disease. |

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.
