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

Genomics promises to revolutionize the study of nutrient function and requi rements and, thereby, solidify the connection of this field to basic scienc es, such as molecular genetics. In this short review, we address the genera l concepts and techniques used in high throughput measurements of gene expr ession. We also speculate on how these technologies can be used to further our understanding of basic metabolism and nutrient regulation of gene expre ssion in developmental and pathological conditions.
