Abstract
Bilirubin is the main waste product of heme catabolism. At high concentrations, bilirubin
may cause toxicity, especially in the brain, kidney, and erythrocytes. Membrane and mitochondrial
dysfunction, oxidative stress, apoptosis, necrosis, endoplasmic reticulum stress, excitotoxicity,
inflammation, and epigenetic modifications are the main mechanisms of toxicity triggered by
bilirubin in susceptible organs. Many studies have shown that there is an interaction between bilirubin
and epigenetic modifications in metabolic and immune diseases. In this review, we first outline the
toxicity mediated by bilirubin and then summarize the current knowledge linking bilirubin and
epigenetic modifications in metabolic and immunometabolic disorders.
Keywords:
Bilirubin, DNA methylation, epigenetic modifications, metabolic disorders, immunometabolic disorder, Wilson’s disease (WD).
