| Abstract | Genetic risk factors of chronic pancreatitis (CP) have been identified and a number of studies have found that CP can lead to pancreatic cancer. Therefore, the detection of pancreatitis-associated gene mutations can aid the pancreatic cancer diagnostic process. Mutations in three genes, the cationic trypsinogen (PRSS1) gene, the cystic fibrosis transmembrane conductance regulator (CFTR) gene and the pancreatic secretory trypsin inhibitor (SPINK1) gene, have been identified as risk factors for CP. The aim of this study was to describe specific novel mutations in the intron of the PRSS1 gene in patients with pancreatic cancer and CP. A total of 65 unrelated patients with pancreatic cancer and 29 with CP were reviewed. Mutations and polymorphisms of the PRSS1 gene were analyzed by direct sequencing. Information regarding clinical data and smoking exposure was collected by personal interviews using a structured questionnaire. IVS 3+36 A>G mutation in the PRSS1 gene was found in 2 cases with pancreatic cancer, and these 2 patients were classified as never-smokers. IVS 3+127 T>A and IVS 3+157 G>C double mutations were identified in one patient with CP. All patients were found to have serum trypsin levels lower than that of the normal controls. Therefore, the PRSS1 gene mutation may be a special common cause of pancreatic cancer and CP. |

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.
