Circadian rhythms have profound influence on metabolic output, UCI study reveals

ching implications for human illness and aging, and it is likely vital for proper metabolism," he said. Study results appear this week in the early online edition of the Proceedings of the National Academy of Sciences.

"By identifying the relationship between metabolites and the body clock, we have taken a first step toward a better understanding of how nutrients interact with our metabolism, giving researchers a new opportunity to spot the optimal times for us to get the fullest benefits from the foods we eat and the medications we take," added Kristin Eckel-Mahan, a UCI postdoctoral researcher in biological chemistry and study co-author.

Working with Metabolon Inc., Sassone-Corsi and Eckel-Mahan created the first liver metabolome the full set of metabolites. With this information, they partnered with Pierre Baldi, director of UCI's Institute for Genomics & Bioinformatics, and his graduate student Vishal Patel to analyze the data and build CircadiOmics, a Web-based data system that provides detailed profiles of the metabolites and related genes in the liver and the underlying networks through which they interact. The CircadiOmics address is http://circadiomics.igb.uci.edu.

"Within CircadiOmics, we were able to integrate this circadian metabolite data with multiple other data sources to generate the first comprehensive map of the liver metabolome and its circadian oscillations and develop regulatory hypotheses that have been confirmed in the laboratory," said Baldi, Chancellor's Professor of computer science. "CircadiOmics is being expanded with metabolic data about other tissues and conditions and will be invaluable to further our understanding of the interplay between metabolism and circadian rhythms in healthy and diseased states."
