| Abstract | Decorin (DCN), a class I member of the small leucine-rich proteoglycan (SLRP) family, is composed of a protein core of approximately 40kDa [1, 2] substituted with a single glycosaminoglycan (GAG) chain of chondroiton/dermatan sulfate on the N-terminal site [3]. DCN has been reported to interact with collagen [4,5] via its core protein, influence collagen fibrillogenesis [6], and inhibit the growth rates of various cell types when added exogenously to cell cultures [5,6]. There has recently been growing interest and studies in DCN related research using the knockout (KO) mice model which provides an excellent example of inherited disorders that stem from deficiencies in decorin expression [7]. Skin and tendon tissues from DCN KO mice have been characterized as being extremely fragile with significantly reduced strength and stiffness [8, 9]. The DCN KO tissues also show potential functional biglycan compensation [9] and at the microscopic level collagen fibrils with highly irregular diameters, abnormal lateral fusion, and loose packing [6] in contrast to wild type (WT) mice. Despite the intensive investigation of the DCN KO mice, the complexity of the animal model makes it difficult to assess the actual influence of decorin. In an attempt to take a more simplistic approach 2D cell phenotypic characterization studies were performed in addition to studying cell growth, contraction, and matrix organization in 3-D models to show the very distinct biochemical responses to type I collagen when compared to WT control cells. |

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.
