“A vast body of literature has suggested genetic programming of preterm birth. However, there is a complete lack of an organized analysis and stratification of genetic variants that may indeed be involved in the pathogenesis of preterm birth. We developed a novel bioinformatics approach to identify the nominal genetic variants associated with preterm birth. We used semantic data mining to extract all published articles related to preterm birth. Genes identified from public databases and archives of expression arrays were aggregated

with genes curated from the literature. Pathway analysis was used to impute genes from pathways identified in the curations. The curated articles and collected genetic Fluorouracil in vitro information are available in a web-based tool, the database for preterm birth (dbPTB) that forms a unique resource for investigators interested in preterm birth. Preterm birth (PTB) is an Acesulfame Potassium important, poorly understood clinical problem. It inures enormous clinical, economic and psychological burdens to society. While recent theories underscore the role of inflammation in preterm labor, simple explanations, single pathways and simple patterns of inheritance are inadequate to explain the pathogenesis of this enigmatic pregnancy complication. The pathogenesis of PTB could be better investigated whether considered a complex, polygenic disorder that entails activation or suppression of a host of genes. We hypothesized that polymorphic changes in the genes that

contribute to the risk of preterm birth could be identified using new bioinformatics approaches coupled with high-throughput technologies applied to appropriate cohorts of patients. This will lead to previously unrecognized insights into the relative contribution of the genetic and environmental factors, which underlie preterm birth. We developed an alternative approach to identify a more manageable set of candidate genes, which nonetheless incorporates some elements of genome-wide investigation. Our approach combined information from published literature with data from expression databases, linkage data and pathway analyses to identify biologically relevant genes for testing in an association study of genetic variants and preterm birth.
