[摘要]：There now exists a resurgence of interest in the role of intermediary metabolism in medicine; especially in relation to medical disorders. Coupled with this is the contemporary focus on molecular biology, genetics and proteomics and their integration into studies of regulation and alterations in cellular metabolism in health and disease. This is a marriage that has vast potential for elucidation of the factors and conditions that are involved in cellular metabolic and functional changes, which heretofore could not be addressed by the earlier generations of biochemists who established the major pathways of intermediary metabolism. The achievement of this present potential requires the appropriate application and interpretation of genetic and proteomic studies relating to cell metabolism and cell function. This requires knowledge and understanding of the principles, relationships, and methodology, such as biochemistry and enzymology, which are involved in the elucidation of cellular regulatory enzymes and metabolic pathways. Unfortunately, many and possibly most contemporary molecular biologists are not adequately trained and knowledgeable in these areas of cell metabolism. This has resulted in much too common inappropriate application and misinformation from genetic/proteomic studies of cell metabolism and function. This presentation describes important relationships of cellular intermediary metabolism, and provides examples of the appropriate and inappropriate application of genetics and proteomics. It calls for the inclusion of biochemistry, enzymology, cell metabolism and cell physiology in the graduate and postgraduate training of molecular biology and other biomedical researchers.
