Secretion of bile is an important excretory route for a wide range of endogenous and exogenous compounds, also known as endobiotics (e.g., bile acids, bilirubin, cholesterol, phospholipids) and xenobiotics (e.g., drugs and their metabolites), which may become toxic when accumulating in the liver [1–3]. Bile acids, the major component of bile, are not only essential for the digestion and absorption of lipids from the intestinal lumen, but also have multiple endocrine functions as regulators of hepatic glucose and lipid metabolism, liver regeneration, inflammation, and intestinal bacterial flora . Cholestasis is an impairment of bile secretion which is typically characterized by reduced bile flow and retention of biliary constituents (normally secreted into bile) in blood, liver, as well as extrahepatic organs and tissues . Histopathologically, cholestasis is characterized by bilirubinostasis with bile plugs and cholate-stasis with feathery degeneration of (mainly periportal) hepatocytes . An excellent, generally applicable definition of cholestasis, irrespective of the cause and etiology, has been coined by Serge Erlinger describing this condition as “failure of bile to reach the duodenum in sufficient amounts” .
