Chronopharmacology is an important but under-explored aspect
of therapeutics. Rhythmic variations in biological processes can
influence drug action, including pharmacodynamic responses,
due to circadian variations in the availability or functioning of drug
targets. We hypothesized that global gene expression analysis
can be useful in the identification of circadian-regulated genes
involved in drug action. Circadian variations in gene expression in
rat liver were explored using Affymetrix gene arrays. A rich time
series involving animals analyzed at 18 time points within the 24-h
cycle was generated. Of the more than 15,000 probe sets on
