It has been implicated in human and experimental animal carcinogenesis.[2][3] Preliminary in vitro research suggests that LCA selectively kills neuroblastoma cells, while sparing normal neuronal cells and is cytotoxic to numerous other malignant cell types at physiologically relevant concentrations.[4]
Dietary fiber can bind to lithocholic acid and aid in its excretion in stool;[5] as such, fiber can protect against colon cancer.
LCA (and LCA acetate and LCA propionate) can activate the vitamin D receptor without raising calcium levels as much as vitamin D itself.[6]
LCA binds with 20 μM affinity to the human membrane enzyme NAPE-PLD, enhancing dimer assembly and enabling catalysis. NAPE-PLD catalyzes the release of anandamide and other N-acylethanolamines (NAE) from the membrane precursor N-acylphosphatidylethanolamine (NAPE). NAPE-PLD facilitates crosstalk between bile acid signals and lipid amide signals.[7][8][9]
LCA has been reported to have anti-aging effects in yeast,[10][11][12] and more recently fruit flies, nematodes, and mice.[13][14]
