Strong Points: Excellent focus

I had to laugh when I saw the URL for this site—bite-it. Those Finns sure know how to catch my attention. Teeth aren’t usually common subjects of discussion here but they are a specialized set of cells in the body. Hence, their gene expression is of interest, and that provides the complete focus of this aptly named site. The design is a little unusual. The central part of the page, which usually gets the most interesting material, simply has instructions about how to start. This consists of clicking on a topic listed in the left panel. Topics specific for teeth include signaling molecules, receptors, in situ hybridization, root development, and information specific for mice, humans, rats, and a few miscellaneous species. Almost every section is full of links to specific genes related to the topic area. Another section of the site, titled Traits and Mutants, contains links to numerous disorders of the teeth, most of which I had never heard of. With its tight focus and well-organized links, Gene Expression in Tooth is poised to serve everyone interested in molars, save possibly the tooth fairy.
