Inhibition of Bilirubin Generation Exacerbates Oxidative Stress and Liver Injury in Early‐to‐Intermediate Obstructive Cholestasis

Key Points

To investigate the impact of bilirubin inhibition on oxidative stress and liver injury in obstructive cholestasis.
Assessment of HO1 inhibition effects on bilirubin levels.
Evaluation of oxidative stress markers in liver tissues.
Analysis of liver injury indicators in an obstructive cholestasis model.
Inhibition of bilirubin led to increased markers of oxidative stress.
Loss of bilirubin exacerbated liver damage during obstructive cholestasis.
Bilirubin accumulation was found to be protective against bile salt toxicity.

Abstract

The inhibition of HO1 and consequent decrease in the endogenous levels of BR negatively impacts the outcome of obstructive cholestasis due to the loss of BR's antioxidant and cytoprotective effects. BR accumulation during cholestasis serves as a critical defence against oxidative damage induced by retained bile salts.
