Many experimental diabetic rat models, such as type 1 (STZ-induced diabetic rats) and type 2 (e.g., Otsuka-Long-Evans-Tokushima-Fatty (OLETF) rats and Zucker Diabetic Fatty (ZDF-rats)) rats, demonstrated elevated expression of VEGF mRNA in the glomerulus [235–237]. The gene discussed is VEGFA; the disease is diabetes mellitus.
