| Abstract | Progression through the various stages of skin tumorigenesis is correlated with an altered expression of the integrin 3ß1, suggesting that it plays an important role in the tumorigenic process. Using epidermis-specific Itga3 KO mice subjected to the 7,12-dimethylbenzanthracene (DMBA)/12-O-tetradecanoylphorbol-13-acetate two-stage skin carcinogenesis protocol, we demonstrate that efficient tumor development is critically dependent on the presence of 3ß1. In the absence of 3ß1, tumor initiation is dramatically decreased because of increased epidermal turnover, leading to a loss of DMBA-initiated label-retaining keratinocytes. Lineage tracing revealed emigration of 3-deficient keratinocytes residing in the bulge of the hair follicle toward the interfollicular epidermis. Furthermore, tumor growth and cell proliferation were strongly reduced in mice with an epidermis-specific deletion of Itga3. However, the rate of progression of 3ß1-null squamous cell carcinomas to undifferentiated, invasive carcinomas was increased. Therefore, 3ß1 critically affects skin carcinogenesis with opposing effects early and late in tumorigenesis. |

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.
