Resistance of three immortalized human hepatocyte cell lines to acetaminophen and N-acetyl-p-benzoquinoneimine toxicity.
841 - 851.
Acetaminophen toxicity in hepatocytes is attributed to generation of the toxic metabolite N-acetyl-p-benzoquinoneimine, leading to depletion of intracellular glutathione, alteration of redox potential and ultimately, cellular necrosis. We aimed to determine the effect of acetaminophen and N-acetyl-p-benzoquinoneimine on three human hepatocyte cell lines HH25, HH29 and HHY41, and for comparison, on primary rat hepatocytes, a cell type that is relatively resistant to acetaminophen-induced toxicity.
