Aim: Kidneys are the organs that play an important role in fluorine metabolism. This study was planned to
investigate the possible role of NaF administration in the NRK-52 kidney line, which causes certain levels
of cytotoxicity.
Methods: Rat renal epitelial NRK-52E (ATCC® CRL-1571™) cell line was cultured in standard cell culture
conditions. NaF concentrations were prepared in the medium (50, 100, 250, 500, 1000, 2000, 5000, 7500,
10000 and 20000 μM). MTT assay was performed to detect the cytotoxic effect of NaF in NRK-52E cells.
The cells treated with NaF at IC50 value dose were divided into 3 groups on time (3, 12 and 24th hours).
Then, total RNA isolation followed by cDNA isolation was performed. Expressions of the necrotic genes
(RIP 1 and RIP 3) were determined by RealTime-PCR.
Results: Ripk1 gene was decreased at 3 and 12 hours and increased at 24 hours. A significant difference
was detected between groups in terms of gene expression pattern. Ripk3 was decreased at 3 hours and
increased at 12 and 24 hours. The change in the 24 hours was significantly higher than in the other groups.
Conclusions: In conclusion, this study was conducted to elucidate the cause of NaF-induced cell death in
renal epithelial cells (NRK-52E). It has been suggested that genes involved in necrotic mechanisms are
gradually up-regulated and necrotic genes become more active.
