Abstract
© 2019 Elsevier Ltd Fibrogenesis is a common feature for all types of chronic kidney disease (CKD). Epithelial-to-mesenchymal transition (EMT) of renal tubular epithelial cells is one of the main processes involving renal fibrosis and its inhibition is considered as a preventive/therapeutic strategy for CKD. Trigonelline (TRIG), a plant alkaloid commonly found in herbs, coffee bean, soy bean and other edible food plants, has several beneficial effects on human health and has been proposed to reduce renal fibrosis but with unclear mechanisms. This study thus addressed cellular mechanism underlying the anti-fibrogenic effects of TRIG in renal tubular epithelial cells grown in vitro. EMT was successfully induced by oxalate treatment as indicated by morphological changes into spindle-shape cells, increased expression of mesenchymal proteins (fibronectin, vimentin and α-smooth muscle actin (α-SMA)), decreased expression of epithelial proteins (E-cadherin and zonula occludens-1 (ZO-1)) and increased activity of a profibrotic factor (matrix metalloproteinase-9 (MMP-9)). Interestingly, these oxalate-induced EMT features could be attenuated by TRIG pretreatment. Moreover, TRIG also prevented oxalate-induced cell migration, reactive oxygen species (ROS) overproduction, and down-regulation of Nrf-2 signaling molecule. These data indicated that TRIG could attenuate the effects of oxalate-induced EMT and thus may serve as the anti-fibrotic compound for prevention and/or treatment of CKD.
