Glycine seems to act at an intracellular site to enhance cyanide production and the process seems to involve a peroxidase mechanism similar to that reported for white blood cells.

The two faces of cyanide: an environmental toxin and a potential novel mammalian gasotransmitter
- BiologyThe FEBS journal
- 2021
Cyanide fulfills many of the general criteria as a ‘classical’ mammalian gasotransmitter and shares some common features with the current members of this class: nitric oxide, carbon monoxide, and hydrogen sulfide.
Oxidative stress and cyclooxygenase-2 induction mediate cyanide-induced apoptosis of cortical cells.
- BiologyToxicology and applied pharmacology
- 2002
The data show that cyanide treatment of cortical cells involves increased COX-2 expression, PGE(2) accumulation, and ROS generation, resulting in apoptotic cell death, and increased nitric oxide levels caused by cyanide may directly activate the COx-2 enzyme.
Nitric oxide and histone deacetylases modulate cocaine-induced mu-opioid receptor levels in PC12 cells
- BiologyBMC Pharmacology and Toxicology

In the PC12 cell model, both nitric oxide and histone deacetylase activity regulate cocaine-induced MOR expression at both the transcriptional and post-transcriptional levels, suggesting epigenetic mechanisms are implicated in cocaine’s action on MOR expression in neurons.

A mitochondria-specific coumarin pyrrolidinium-derived fluorescence probe (MRP1) that permits the real-time ratiometric imaging ofHCN in living cells and has proved effective in visualizing different concentrations of exogenous HCN in the mitochondria of HepG2 cells, as well as the imaging of endogenous HCN within neurons.

A critical analysis of acute CO and CN poisonings evidences that the lone toxicological similarity between CO andCN is their ability to avidly bind iron ions in the different hemoproteins, further supporting different mechanisms of action.
Inhibition by naloxone of promoter activity of the neurofilament gene in SK-N-SH cells.

It is suggested that naloxone has the ability to suppress transcriptional activity in some neurons by inhibition by dose-dependent and not reversed by morphine.

Since PC12 cells rapidly respond to cyanide, with predictable depletions of the cell adenylate energy pool, this cell line can serve as a suitable in vitro model for studies of neurotoxicity involving ischemic/hypoxic conditions.

It is shown that physiological concentrations of H2S selectively enhance NMDA receptor-mediated responses and facilitate the induction of hippocampal long-term potentiation, suggesting that endogenous H 2S functions as a neuromodulator in the brain.

Findings indicate that direct regulation of IP3R by NADH is responsible for elevated cytoplasmic [Ca2+] occurring in the earliest phase of hypoxia, and may be relevant to both hypoxic damage and metabolic regulation ofIP3 signaling processes.
