Bile acids are essential for solubilization and transport of dietary lipids, are the major products of cholesterol catabolism, and are physiological ligands for farnesoid X receptor (FXR), a nuclear receptor that regulates genes involved in lipid metabolism.1 They are also inherently cytotoxic, as physiological imbalance contributes to increased oxidative stress.2,3 Bile acid-controlled signaling pathways are promising novel targets to treat such metabolic diseases as obesity, type II diabetes, hyperlipidemia, and atherosclerosis. Chenodeoxycholic acis (CDCA) is a hydrophobic primary bile acid that activates nuclear receptors involved in cholesterol metabolism.3,4 EC50 concentrations for activation of FXR range from 13-34 μM.5,6 In cells, CDCA also binds to bile acid binding proteins (BABP) with a reported stiochiometery of 1:2.4 CDCA toxicity is linked to increased cellular glutathione levels and increased oxidative stress. Exposure of cells to excess CDCA contributes to liver and intestinal cancers.3
