Nephrotoxicity and ototoxicity are the most considerable side effects of aminoglycoside antibiotics, such as gentamicin that seriously limits its application in medicine. The major mechanism of negative effect of gentamicin on kidney cells involves damage of mitochondria and induction of an oxidative stress that causes cell death resulting in kidney dysfunction. In this work we compared effects of the lithium ions and delta-opioid receptors agonist, dalargin on gentamicin-induced kidney injury. It was revealed that LiCl and dalargin treatment reduced renal tubular cell death and diminished kidney injury caused by gentamicin. Both LiCl and dalargin were found to enhance phosphorylation of glycogen synthase kinase 3 beta in the kidney which points to induction of nephroprotective signaling pathways. Thus, we conclude that lithium ions and dalargin might be considered as novel promising agents for future use to prevent negative consequences of therapy with aminoglycoside antibiotics.
