Eucalyptol repressed the stimulation of proteins implicated in the epithelial-mesenchymal transition, including β-catenin, Snail1, and integrin-1-related kinase (ILK1), in tubular cells displayed to glucose and in kidneys impacted by diabetes, while reversing the expression of glycogen synthase kinase (GSK)-3β. The gene discussed is GSK3B; the disease is diabetes mellitus.
