| Abstract | Angiogenesis is essential for tumor growth, progression and metastasis. Studies indicate that expression and activity of ecto-5′-nucleotidase (CD73) are elevated in metastatic carcinomas. Our previous studies found that angiogenesis of tumor xenografts was decreased when the activity of CD73 in cancer cells was inhibited, implying that this enzyme is involved in tumor angiogenesis. To elucidate the mechanism, we investigated CD73 influence on tumor angiogenesis in both in vitro assays and in tumor bearing mice. We found that capillary-like structures were formed more in CD73+/+ pulmonary microvascular endothelial cells (PMECs) than CD73−/− PMECs, and this was more pronounced when the cells were cultured in cancer-conditioned medium. Meanwhile, CD73 decreased endothelial cells adhesion to collagen IV and promoted migration. Additionally, the extent of tumor angiogenesis and the size of tumors were greater in CD73+/+ mice than in CD73−/− mice. Thus, we concluded that CD73 can promote endothelial cells forming new vessels in cancer condition, facilitating tumor growth and hematogenous metastasis. |

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.
