Mechanism of Action

In vitro	Tauroursodeoxycholic acid (TUDCA) is an endogenous hydrophilic tertiary bile acid produced in humans at a low level. In ER stress conditions, treatment with this compound reduces the activation of ER stress-associated proteins, including GRP78, PERK, eIF2α, ATF4, IRE1α, JNK, p38, and CHOP, and inhibits the dissociation between GRP78 and PERK, resulting in reduced ER stress-mediated cell death. It also increases PrP^C (Cellular prion protein) expression. TUDCA regulates stem cell differentiation into various lineages such as adipogenic and osteogenic lineages. It attenuates ER stress, prevents unfolded protein response dysfunction, and stabilizes mitochondria. Under ER stress, treatment with this compound significantly increases the expression of BCL-2 and significantly decreases the expression of Bax, cleaved caspase-3, and cleaved PARP-1, compared with that of untreated cells.
In vivo	Tauroursodeoxycholic Acid (TUDCA) is effective for treating cholestatic liver diseases and also has an ameliorating effect on several diseases, including neurodegenerative diseases, osteoarthritis, vascular diseases, and diabetes. In a murine hindlimb ischemia model, TUDCA-treated mesenchymal stem cells (MSCs) transplantation augments the blood perfusion ratio, vessel formation, and transplanted cell survival more than untreated MSC transplantation does. Augmented functional recovery following MSC transplantation is blocked by PrP^C downregulation. Several studies in animals have shown that this compound, an endogenous ambiphilic bile acid, can inhibit unfolded protein response dysfunction and ameliorate ER stress. Its administration attenuates HDM-induced ER stress, airway inflammation, mucus metaplasia, airway remodeling, and methacholine-induced AHR.
