Hepatocyte-specific Gclch/h knockout strain

The Gclch/h mouse line was created by crossing Gclcf/f and Alb-Cre mice (1). Gclch/h mice experience almost complete loss of hepatic GSH (5% of normal) and die from acute liver failure when mitochondrial failure occurs. Chronic administration of N-acetyl-cysteine, a treatment that promotes only a mild increase in liver GSH levels (to 8% of normal) but partially preserves mitochondrial function, allows Gclch/h mice to survive to adulthood, albeit with the still serious liver fibrosis and cirrhosis (2). Gclch/h mice demonstrate liver pathologies reminiscent of those occurring at the various clinical stages of alcoholic liver disease.
