Based on relevant literature and functional information in databanks, we assigned a function and a possible type(s) of cell(s) responsible for expression for most of the genes on our list (Fig. 3) . In this hypothetical model, information from existing models dealing with the pathogenesis of rotavirus infection [29, 39, 40] and the development and maintenance of the small intestinal epithelium [20] were used to fit in our data. Possible functions of these genes in relation to processes and pathways known to be important for rotavirus pathogenesis are discussed below.
