This experiment investigates the temporal dynamics in gene expression upon Orsay virus infection in the nematode Ceanorhabditis elegans. Three different strains were infected: JU1580, N2, and CB4856. Of these, JU1580 is highly susceptible, N2 moderately susceptible, and CB4856 the most resistant strain. The goal of the experiment was to identify genes that show different expression dynamics over the time-course of the infection. We (mock-)infected 40h-old C. elegans populations with Orsay virus and took samples over a 32-hour spanning time-course. For each treatment-strain combination 12 samples were collected. Thereafter RNA was isolated, labelled, and hybridized on microarray. The gene-expression dynamics of previously identified genes (e.g. from literature and from a highly replicated N2 versus CB4856 experiment) were analyzed.
