Simplified, “classic” model of the pathogenesis of glomerulosclerosis. High extracellular glucose leads to increased mesangial cell glucose uptake via enhanced expression of the facilitative glucose transporter GLUT1, activating metabolic pathways that result in increased ROS and AGE generation, which in turn activate a number of signaling pathways that augment ECM production directly via protein kinase Cβ stimulation of AP-1 transcriptional activation, ERK pathways, and, critically, TGF-β1 synthesis, which in an autocrine and paracrine fashion stimulates its signaling pathways to further enhance ECM protein synthesis. Ang II, angiotensin II; DAG, diacylglycerol; PKC, protein kinase C; ROS, reactive oxidant species.
