Summary: This study evaluated the impact of glyoxal-lysine dimer (GOLD) on oxidative damage and inflammatory response in SV40 MES 13 mesangial cells. GOLD increased RAGE expression, reactive oxygen species production, and regulated NRF2 and GLO1 expression. Additionally, GOLD induced mitochondrial deterioration and inflammation through oxidative stress, and regulated MAPK and proinflammatory cytokines release. Inhibition of RAGE using RAGE siRNA suppressed the oxidative stress and inflammatory responses triggered by GOLD, highlighting the importance of the interaction between GOLD and RAGE in mesangial cell function.

Summary: The study characterized MG-modified myoglobin in a time-dependent manner, with mass spectrometric studies indicating modifications at Lys-87 and Lys-133. Far-UV CD studies revealed alterations in protein structure and surface hydrophobicity as a result of MG modification. These findings suggest that MG-derived AGE adducts significantly impact the structure of Mb.

Summary: Endophytes, microorganisms that live in plants, have the potential to produce bioactive compounds, including anti-aging compounds. This study discusses the importance and challenges of using endophytes as a source of anti-aging compounds, focusing on 26 plant compounds and derivatives that have been reported as endophytic metabolites.

Summary: In thermally processed foods, heat-induced toxicants such as alpha-dicarbonyls and advanced glycation end products (AGEs) can be formed. The methylglyoxal (MGO)-trapping and antiglycative activities of herbal tea samples are strongly correlated with their phenolic and flavonoid contents. Rooibos tea exhibits the strongest MGO-trapping and antiglycative activities, reducing the levels of dicarbonyls and AGEs in cookies.

Summary: This study examined the effect of five different types of AGEs on HepG2 cells and found that AGE2 to 5 increased the production of reactive oxygen species (ROS) in liver cells, leading to apoptosis. AGE5 treatment showed the greatest increase in the expression of apoptosis-related factors. N-epsilon-carboxymethyl-lysine (CML) and glyoxal-lysine dimer (GOLD) were identified as important AGE compounds in AGE5.

Summary: This study prepared Penta-O-galloyl-beta-D-glucose (PGG) from tannic acid methanolysis products and investigated its protective effects and mechanism on glucose-induced glycation for the first time. PGG was found to have strong anti-AGEs effects in bovine serum albumin (BSA)-glucose (Glu) and BSA-methylglyoxal (MGO) glycation systems. It inhibits AGEs formation by blocking glycated intermediates, eliminating radicals, and chelating metal ions. Mechanism analysis showed that PGG prevents BSA from glycation by hindering amyloid fibril accumulation, stabilizing BSA secondary structures, and binding partial glycation sites. PGG also displays effective trapping capacities on MGO reactive intermediate. This research suggests PGG as a potential functional ingredient in food materials for preventing diabetic syndrome.

Summary: This study found that a low-AGE diet significantly alters circulating metabolomes and lipidomes, including sphingolipid, ether-lipid, and glycerophospholipid metabolism. This dietary approach can reproduce some plasma characteristics of healthy aging.

Summary: We identified a mitochondrial protein, GATD3A, with bacterial evolutionary affinities, that functions as a deglycase and restricts the formation of AGEs in mitochondria. GATD3A may play a role in maintaining the integrity of important biomolecules.

Summary: This review examines the antiglycation effect and mechanism of tea and tea polyphenols. The findings suggest that tea polyphenols, particularly catechins, have a significant antiglycation effect by trapping alpha-dicarbonyl compounds and impeding the formation of advanced glycation end products (AGEs). Additionally, tea polyphenols alleviate aging, diabetes, and collagen-related diseases or complications through the regulation of receptor for advanced glycation end products (RAGE) expression and subsequent MAPK and TGF-beta pathways.

Summary: This study compared the effects of different frying methods on the formation of AGEs in sturgeon patties and found that pan-fried and deep-fried patties had different levels of AGEs. Deep-fried patties had higher levels of CML compared to pan-fried patties, and this increase was positively correlated with frying time. The formation of AGEs during cooking was positively associated with temperature and amino groups, while negatively correlated with moisture content.
