1. A method of screening a drug for deleterious side effects on a cell comprising the steps of:
- assaying for the amount of expression in the cell of two or more genes selected from the group consisting of;
G6PD, calcium channel, synaptotagamin, neuromodulin, calmodulin, nicotinic acetylcholine receptor beta 2, VLDLR, udulin1/undulin/extracellular matrix glycoprotein, pyruvate dehydrogenase E1, apolipoprotein B100, hepatocyte gf, IGF binding protein 1, ubiquitin, bone morphogenetic protein precursor, cytochrome p450-2E1, and thymosin beta-10, wherein the expression in the cell is assayed before and after the cell has been contacted with the drug, wherein alteration of the amount of expression of at least one of these genes by the drug is indicative of a deleterious side effect.

Abstract
Expression profiles have been constructed for liver and brain, in adult and fetal and adolescent tissue. These provide the art with probes which are highly differentially expressed among stages and organs. The profiles and probes can be used to prioritize potential drug targets, to monitor disease progression and remission, and to assess drug metabolism. Solid supports are also provided which facilitate these uses.
