The patient with end-stage renal disease show several nervous complications. The factors contributing to the nervous complications are still incompletely characterized. Cyanate, known as one of the uremic toxins, is derived spontaneously from urea. To investigate the mechanism of cyanate-induced effect on C6 glioma cells, the glioma cells were treated with 0, 1, 5, 10, 20 and 40 mM cyanate. There was a dose-dependent decrease in cell viability and the decreased number of cell was observed in glioma cells by treatment with cyanate. Western blot showed the down- regulation of procaspase-3, which means up-regulation of caspase-3, and the up-regulation of caspase-8, but the down-regulation by cyanate. In addition, cDNA microarray showed 934 down-regulated genes and 165 up-regulated genes on 1,099 genes in cyanate treated group. Treatment with cyanate led to 16 down-regulated genes and 6 up-regulated genes on apoptosis category, and especially heat shock 70 kD protein 1A gene on the category of apoptosis was significantly up-regulated. These results suggest that cyanate can induce apoptosis through caspase-8 and caspase-3 in glioma cells and decrease of gene expression including apoptosis category in glioma cells. These effects of cyanate may play a role in the nervous complications of patient with end-stage renal disease.
