Alpha-ketoglutarate and N-acetyl cysteine protect PC12 cells from cyanide-induced cytotoxicity and altered energy metabolism.


Cyanide is a rapidly acting neurotoxin that inhibits cellular respiration and energy metabolism leading to histotoxic hypoxia. This results in the dissipation of mitochondrial membrane potential (MMP) accompanied by decreased cellular ATP content which in turn is responsible for increased levels of intracellular calcium ions ([Ca(2+)](i)) and total lactic… (More)
