MEASUREMENT OF FGF21 AS A BIOMARKER OF FRUCTOSE METABOLISM AND METABOLIC DISEASE

摘要

The invention provides, inter alia, methods of monitoring the fructose response of a subject by determining the level of fibroblast growth factor 21 (FGF21) gene expression product in a biological sample (such as a serum sample) from the subject, where the subject was previously administered a fructose bolus. The invention also provides methods of monitoring the response of a subject to a treatment for a disorder of metabolism, for discriminating fructose intolerance from other gastrointestinal disorders not associated with fructose intolerance, for identifying a subject at risk for developing a disorder of metabolism, as well as methods of treatment for a disorder of metabolism.
