TAGE病因説

Advanced glycation end-products (AGEs) generated with aging or in the presence of diabetes mellitus, particularly AGEs derived from the glucose/fructose metabolism intermediate glyceraldehyde (Glycer-AGEs; termed toxic AGEs (TAGE)), were recently shown to be closely involved in the onset and progression of diabetic vascular complications via the receptor for AGEs (RAGE). TAGE also contribute to various diseases, such as cardiovascular disease, nonalcoholic steatohepatitis, cancer, Alzheimer’s disease, and infertility. This suggests the necessity of minimizing the influence of the TAGE-RAGE axis in order to prevent the onset and progression of lifestyle-related diseases (LSRD) and establish therapeutic strategies. Changes in serum TAGE levels are closely associated with LSRD related to overeating, a lack of exercise, or excessive ingestion of sugars/dietary AGEs. We also showed that serum TAGE levels, but not those of hemoglobin A1c (HbA1c), glucose-derived AGEs, or N-(carboxymethyl)lysine, have potential as a biomarker for predicting the progression of atherosclerosis and future cardiovascular events. We have also demonstrated the usefulness of serum TAGE levels as a biomarker for the prevention and early diagnosis of LSRD and the evaluation of the efficacy of treatments. We aim to show whether dietary AGE/sugar intake restrictions reduce the generation and accumulation of TAGE, thereby preventing the onset and progression of LSRD.
