Expression sequence tag library derived from peripheral blood mononuclear cells of the chlorocebus sabaeus.

Abstract : ABSTRACT: BACKGROUND: African Green Monkeys (AGM) are amongst the most frequently used nonhuman primate models in clinical and biomedical research, nevertheless only few genomic resources exist for this species. Such information would be essential for the development of dedicated new generation technologies in fundamental and pre-clinical research using this model, and would deliver new insights into primate evolution. RESULTS: We have exhaustively sequenced an Expression Sequence Tag (EST) library made from a pool of Peripheral Blood Mononuclear Cells from sixteen Chlorocebus sabaeus monkeys. Twelve of them were infected with the Simian Immunodeficiency Virus. The mononuclear cells were or not stimulated in vitro with Concanavalin A, with lipopolysacharrides, or through mixed lymphocyte reaction in order to generate a representative and broad library of expressed sequences in immune cells. We report here 37,787 sequences, which were assembled into 14,410 contigs representing an estimated 12% of the C. sabaeus transcriptome. Using data from primate genome databases, 9,029 assembled sequences from C. sabaeus could be annotated. Sequences have been systematically aligned with ten cDNA references of primate species including Homo sapiens, Pan troglodytes, and Macaca mulatta to identify ortholog transcripts. For 506 transcripts, sequences were quasi-complete. In addition, 6,576 transcript fragments are potentially specific to the C. sabaeus or corresponding to not yet described primate genes. CONCLUSION: The EST library we provide here will prove useful in gene annotation efforts for future sequencing of the African Green Monkey genomes. Furthermore, this library, which particularly well represents immunological and hematological gene expression, will be an important resource for the comparative analysis of gene expression in clinically relevant nonhuman primate and human research.
