Molecular approaches to studying nutrient metabolism and function: an array of possibilities.

Genomics promises to revolutionize the study of nutrient function and requirements and, thereby, solidify the connection of this field to basic sciences, such as molecular genetics. In this short review, we address the general concepts and techniques used in high throughput measurements of gene expression. We also speculate on how these technologies can be used to further our understanding of basic metabolism and nutrient regulation of gene expression in developmental and pathological conditions.
