Sodium cyanide (NaCN)-induced chemical hypoxia is known to increase intracellular free calcium concentration and reduce cell survival, but its effect on gene expression has not been studied.
The NaCN-induced hypoxia was also found to increase caspase-3 cellular activity in both cell types.

To examine neurofilament (NF) aggregate-mediated sensitization of motor neurons to NMDA excitotoxicity, we examined NMDA receptor expression and the impact of NO donors (NOC12 or NOC5) or sodium cyanide (NaCN) on calcium influx and viability in dissociated motor neurons derived from wt and hNFL+/+ (NF aggregate-forming) mice.
Alterations in intracellular calcium were assayed using Oregon Green calcium dye and the extent of apoptosis using active caspase-3 immunoreactivity.

Early mitochondrial swelling and loss of the mitochondrial membrane potential were accompanied by release of cytochrome c and followed by caspase-9-dependent activation of caspase-3.

To test these hypotheses, renal epithelial cells were transiently ATP depleted with sodium cyanide and 2-deoxy-D-glucose in the absence of medium dextrose.
Concomitant with mitochondrial cytochrome c leak, a seven- to eightfold increase in caspase 3 activity was observed.

They showed early mitochondrial swelling, loss of mitochondrial membrane potential and cytoplasmic release of cytochrome c, followed by activation of caspase-9, and by caspase-9-dependent activation of caspase-3.

Sodium cyanide-induced chemical hypoxia triggers a series of biochemical alterations leading to apoptosis in many cell types, including T cells.
The inhibition of iNOS limited T-cell apoptosis by decreasing the activity of caspase-3 without affecting the expression of Fas/Apo-1/CD95 on the surface membrane of T cells.

Based on two observations, (a) potentiation of the cytotoxic effect of SNP when coincubated with ferricyanide or ferrocyanide, but not sodium cyanide, and (b) protection by deferoxamine, an iron cyanide chelator, we conclude that the greater sensitivity of N20.1 cells to SNP compared with SNAP is due to synergism between NO released and the iron cyanide portion of SNP, with the cyanide accounting for very little of the cytotoxicity.
