Metabonomics and the endocrine system.
Proton-NMR-based metabonomics offers a rare opportunity as a definitive screening technique for biofluids and tissue biopsies. The procedure is extraordinary in that it allows the 'complete biochemical picture' to be examined at one time and is able to detect subtle but repeatedly consistent disparities that may be occurring in different, and perhaps unrelated, biochemical pathways. Such metabolic responses to an initial perturbation in homeostasis may be followed over a sequential time-course to their eventual dissipation or consequent sequelae. The application of this technique is beginning slowly to filter into the area of endocrine research and has been used to examine long-term and diffuse physiological alterations that may occur following such events as anabolic steroid treatment of cattle and the exposure of endometrial cells to tamoxifen. Although only modest inroads have been made so far, this technique promises immense potential for future researches within the endocrine field.
