Different casts of genes keep a pancreas cell squirting out insulin and a brain cell chattering with its neighbors. Compare gene activity in various cells and tissues with this free database of human and mouse gene chip studies from the Novartis Research Foundation in San Diego, California. The measurements cover several hundred genes, from the insulin receptor to cytochrome c, profiling their expression levels in tissues ranging from the salivary gland to melanoma tumor cells. Find a gene by name or sequence, or sort out the genes that increase or decrease their activity by a selected amount in different tissues.
