We report on the integration of a number of RT-PCR expression datasets totalling 102 genes across 49 experimental conditions of relevance to gastro-intestinal nematodes in sheep. The experimental conditions include three challenge trials, six tissues, five genotypes and two parasites surveyed at multiple time points. After mining gene interaction data for these 102 genes, we have generated an interaction network that enabled us to study these genes in a biologically relevant, system context. Following a systematic investigation of this network, we have identified a number of genes encoding extracellular matrix proteins that may be useful biomarkers enabling identification of parasite resistant sheep.
