Zusammenfassung
Keratins 8 and 18 (K8/K18) are the intermediate filaments of digestive epithelia and display an important hepatoprotective function. Accordingly, K8/K18 variants predispose humans to chronic liver disease and to acetaminophen toxicity. Given that K8 G62C and K8 R341 H/C are abundant K8 variants in European population, we studied their importance using newly generated/previously described mice subjected to acetaminophen (APAP) overdose. Under basal conditions, K8 G62C/K8 R341 C/H mice did not show any obvious liver phenotype or altered keratin distribution pattern. 18 hours after APAP administration (600 mg/kg),…
