| Abstract | The aim of this study was to investigate the expression of Delta-like ligand 4(DLL4) and Endoglin(CD105) labeled microvessel density(MVD) in pancreatic ductal adenocarcinoma (PDAC) and evaluate their correlation with major clinicopathologic features and patients' survival. Forty-two pancreatic cancer and 20 normal pancreatic tissues were included in the study. Immunohistochemical staining was employed to assess the expression level of DLL4 both in tumor cells and stromal vascular endothelial cells, as well as CD105 which was used to determine MVD. The relationships of DLL4 and CD105 expression with clinicopathologic parameters and clinical outcome were evaluated. Both DLL4 and CD105-labeled microvessel were observed highly immunostained in PDAC cases, and high expression of DLL4 was positively correlated with MVD. Moreover, the high expression of DLL4 was significantly associated with histological grade, node stage and TNM stage in not only the cancer cells but also stroma; while high expression of CD105 was associated with histological grade, TNM stage, node stage and distant metastasis. In univariant analysis, patients with high expression of DLL4 and CD105 tended to significantly poorer overall survival. Both DLL4 and CD105 were overexpressed in a large proportion of patients with PDAC. The expression of DLL4 was positively correlated with CD105-labeled MVD, indicating DLL4 may involved in angiogenesis. In addition, high DLL4 and CD105 expression correlated with the poor clinical outcome and overall survival in patients with PDAC. |

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.
