The present study provides a novel approach for klotho gene therapy and demonstrates that direct up-regulation of klotho in the brain might improve aging-related memory impairments and decrease oxidative stress. The underlying mechanism of this effect likely involves the inhibition of the Akt/FoxO1 pathway.

Maillard reaction (MR) is a non-enzymatic browning reaction commonly seen in food processing, which occurs between reducing sugars and compounds with amino groups. Despite certain advantages based on Maillard reaction products (MRPs) found in some food for health and storage application have appeared, however, the MR occurring in human physiological environment can produce advanced glycation end products (AGEs) by non-enzymatic modifi cation of macromolecules such as proteins, lipids and nucleic acid, which could change the structure and functional activity of the molecules themselves. In this review, we take AGEs as our main object, on the one hand, discuss physiologic aging, that is, age-dependent covalent cross-linking and modifi cation of proteins such as collagen that occur in eyes and skin containing connective tissue. On the other hand, pathological aging associated with autoimmune and infl ammatory diseases, neurodegenerative diseases, diabetes and diabetic nephropathy, cardiovascular diseases and bone degenerative diseases have been mainly proposed. Based on the series of adverse effects of accelerated aging and disease pathologies caused by MRPs, the possible harm caused by some MR can be slowed down or inhibited by artifi cial drug intervention, dietary pattern and lifestyle control. It also stimulates people's curiosity to continue to explore the potential link between the MR and human aging and health, which should be paid more attention to for the development of life sciences.
