Abstract

Circadian rhythms are common to most organisms and govern much of homeostasis and physiology. Since a significant fraction of the mammalian genome is controlled by the clock machinery, understanding the genome-wide signaling and epigenetic basis of circadian gene expression is essential. BMAL1 is a critical circadian transcription factor that regulates genes via E-box elements in their promoters. We used multiple high-throughput approaches, including chromatin immunoprecipitation-based systematic analyses and DNA microarrays combined with bioinformatics, to generate genome-wide profiles of BMAL1 target genes. We reveal that, in addition to E-boxes, the CCAATG element contributes to elicit robust circadian expression. BMAL1 occupancy is found in more than 150 sites, including all known clock genes. Importantly, a significant proportion of BMAL1 targets include genes that encode central regulators of metabolic processes. The database generated in this study constitutes a useful resource to decipher the network of circadian gene control and its intimate links with several fundamental physiological functions. © 2010, American Society for Microbiology.
