PG - 445-59 AB - We investigated for the interaction between the polyol pathway and enhanced non-enzymatic glycation, both implicated in the pathogenesis of diabetic atherosclerosis, in the activation of aortic smooth muscle cell (SMC) function. Mouse aortas and primary cultures of SMCs from wildtype (WT) mice and transgenic (TG) mice expressing human aldose reductase (AR) were studied regarding changes in AR activity, and SMC gene activation, migration and monocyte adhesion, in response to advanced glycation end-product modified BSA (AGE-BSA). Results showed that AGE-BSA increased AR activity in both WT and TG aortas, with greater increments (p < 0.05) in TG aortas which, basally, had elevated AR activity (2.8 fold of WT). These increments were attenuated by zopolrestat, an AR inhibitor. Similar AGE-induced increments in AR activity were observed in primary cultures of aortic SMCs from WT and TG mice (60% and 100%, respectively, P < 0.01). Such increments were accompanied by increases in intercellular adhesion molecule-1 (ICAM-1) and monocyte chemoattractant protein-1 (MCP-1) mRNA levels (both P < 0.05), activation of membrane-associated PKC-beta1 (P < 0.05) as well as increased SMC migration and Tamm-Horsfall protein (THP)-1 monocyte adhesion to SMCs (both p < 0.01), with all changes being significantly greater in TG SMCs (P < 0.05) and suppressible by either zopolrestat or transfection with an AR antisense oligonucleotide. Our findings suggest that the effects of AGEs on SMC activation, migration and monocyte adhesion are mediated partly through the polyol pathway and, possibly, PKC activation. The greater AGE-induced changes in the TG SMCs have provided further support for the dependency of such changes on polyol pathway hyperactivity.
