Abstract
Background Drug-induced nephrotoxicity is an important side effect of many commonly used drugs. In this study, we planned to evaluate the effects of teneligliptin (TG), which is a dipeptidyl peptidase-4 (DPP-4) inhibitor, on cell healing by creating nephrotoxicity models in human renal proximal tubule cell and human embryonic kidney epithelial cells cell lines in-vitro with cisplatin, vancomycin, and gentamicin. Methodology First, we determined the 50% inhibitory concentration doses of nephrotoxic drugs and the nephroprotective dose of TG. Then, we analyzed the difference in cell viability, apoptosis, and oxidative stress (reactive oxygen and nitrogen species (ROS/RNS) production) between TG-treated and untreated cells after nephrotoxicity occurred. Moreover, we evaluated the expression of kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) in cells. Results We found that when cell lines were treated after toxicity was induced with TG, cell viability increased, apoptosis and ROS/RNS production were significantly decreased, and expressions of KIM-1 and NGAL were significantly reduced. Conclusions This study showed that TG has positive effects on the recovery of drug-induced nephrotoxicity in an in-vitro setting.
