製品説明	Tauroursodeoxycholic acid (TUDCA) is the taurine conjugate of ursodeoxycholic acid (UDCA) that acts as a mitochondrial stabilizer and anti-apoptotic agent in several models of neurodegenerative diseases, including AD, Parkinson's diseases (PD), and Huntington's diseases (HD).

In Vitro
In vitro	Tauroursodeoxycholic acid (TUDCA) is an endogenous hydrophilic tertiary bile acid produces in humans at a low level. In ER stress conditions, TUDCA treatment of MSCs (mesenchymal stem cells) 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. TUDCA treatment increases PrP^C (Cellular prion protein) expression. TUDCA regulates stem cell differentiation into various lineages such as adipogenic and osteogenic lineages. TUDCA attenuates ER stress, prevents unfolded protein response dysfunction, and stabilizes mitochondria. Under ER stress, treatment with TUDCA 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^[1].

	濃度	100 μM
	反応時間	30 min
	実験の流れ	MSCs are washed twice with phosphate buffer saline (PBS), and fresh α-MEM supplemented with 10% FBS is added. To investigate the apoptosis signaling pathway, MSCs are pretreated with TUDCA (100 μM) at 37 °C for 30 min and then treated with H2O2 (200 μM) for various times (0, 2, 4, 6, or 8 h). To assess another cell signaling pathway, MSCs are treated with an Akt inhibitor (10⁻⁶ M) for 30 min at 37 °C before treatment with TUDCA.

In Vivo
In Vivo	TUDCA is effective for treating cholestatic liver diseases. It 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^[1]. Several studies in animals have shown that TUDCA, an endogenous ambiphilic bile acid, can inhibit unfolded protein response dysfunction and ameliorate ER stress. TUDCA administration attenuates HDM-induced ER stress, airway inflammation, mucus metaplasia, airway remodeling, and methacholine-induced AHR^[2].
