| Abstract | The swine is an important animal model for allo- and xeno-transplantation donor studies, which necessitates an extensive characterization of the expression and sequence variations within the highly polygenic and polymorphic swine leukocyte antigen (SLA) region. Massively parallel pyrosequencing is potentially an effective new 2ndGen method for simultaneous high-throughput genotyping and detection of SLA class I gene expression levels. In this study, we compared the 2ndGen method using the Roche Genome Sequencer 454 FLX with the conventional method using sub-cloning and Sanger sequencing to genotype SLA class I genes in five pigs of the Clawn breed and four pigs of the Landrace breed. We obtained an average of 10.4 SLA class I sequences per pig by the 2ndGen method, consistent with the inheritance data, and an average of only 6.0 sequences by the conventional method. We also performed a correlation analysis between the sequence read numbers obtained by the 2ndGen method and the relative expression values obtained by quantitative real-time PCR analysis at the allele level. A significant correlation coefficient (r = 0.899, P < 0.01) was observed between the sequence read numbers and the relative quantitative values for the expressed classical SLA class I genes SLA-1, SLA-2, and SLA-3, suggesting that the sequence read numbers closely reflect the gene expression levels in white blood cells. Overall, five novel class I sequences, different haplotype-specific expression patterns and a splice variant for one of the SLA class I genes were identified by the 2ndGen method at greater efficiency and sensitivity than the conventional method. |

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.
