PG - 1426-35 LID - 10.1002/mnfr.201300910 [doi] AB - SCOPE: Antiglycative effects of glycyrrhizic acid (GA) in kidney of diabetic mice were examined. METHODS AND RESULTS: GA at 0.05, 0.1, and 0.2% was supplied to diabetic mice for 9 wk. Results showed that GA intake increased its deposit in kidney, raised plasma insulin level, decreased plasma glucose and blood urine nitrogen levels, and improved creatinine clearance rate (p < 0.05). GA intake dose-dependently reduced renal carboxymethyllysine level, and at 0.1 and 0.2% decreased plasma HbA1c, urinary glycated albumin, and renal pentosidine levels (p < 0.05). Dietary GA intake declined renal aldose reductase activity and protein expression, as well as lowered renal fructose and sorbitol levels (p < 0.05). GA intake dose-dependently increased glyoxalase-1 activity and expression, and decreased renal methylglyoxal level (p < 0.05). This compound at 0.1 and 0.2% raised glyoxalase-2 activity and protein expression, and increased d-lactate formation (p < 0.05). GA intake dose-dependently suppressed renal expression of nuclear factor kappa B (NF-kappaB) p65 and p-p38, decreased reactive oxygen species production, and retained glutathione content (p < 0.05). This compound at 0.1 and 0.2% downregulated renal expression of NF-kappaB p50 and p-ERK1/2 (p < 0.05), and lowered renal level of monocyte chemoattractant protein-1 (MCP-1) and intercellular adhesion molecule-1 (ICAM-1). CONCLUSIONS: These findings suggest that glycyrrhizic acid is an antiglycative and renal-protective agent. CI - (c) 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
