| Description | Tauroursodeoxycholate Sodium is an endoplasmic reticulum (ER) stress inhibitor. Tauroursodeoxycholate significantly reduces expression of apoptosis molecules, such as caspase-3 and caspase-12. Tauroursodeoxycholate also inhibits ERK.In Vitro:Tauroursodeoxycholate (TUDCA) suppresses both viability and migration of vascular smooth muscle cells (VSMCs) through inhibition of ERK phosphorylation, by induction of mitogen-activated protein kinase phosphatase-1 (MKP-1) via PKCα. Tauroursodeoxycholate inhibits both the proliferation and migration of VSMCs via inhibition of ERK, through Ca2+-dependent PKCα translocation. Tauroursodeoxycholate prevents platelet-derived growth factor (PDGF) and vascular injury-induced MMP-9 expression. The knock-down of MKP-1 using specific si-RNA restores the reduced VSMC viability by Tauroursodeoxycholate (200 μM), which suggests that anti-proliferative effect of Tauroursodeoxycholate depended on the MKP-1 expression[1].In Vivo:The effects of Tauroursodeoxycholate (TUDCA) on proliferation and apoptosis of VSMCs in vivo are examined using immunohistochemistry for proliferating cell nuclear antigen (PCNA) and the transferase dUTP nick-end labelling (TUNEL) assay. Tauroursodeoxycholate (10, 50, and 100 mg/kg) increases the caspase 3 activity of injured tissues in a dose-dependent manner, indicating that Tauroursodeoxycholate induces apoptosis of VSMCs in the neointima. Using the injured tissues, further examination and comparison of the phosphorylation level of ERK and MMP-9 expression is performed at 1 week after injury, compared with normal controls. Balloon injury increased both the phosphorylation of ERK and expression of MMP-9 in the tissues. Tauroursodeoxycholate (10, 50, and 100 mg/kg) inhibits phosphorylation of ERK and MMP-9 expression in a dose-dependent manner[1]. Tauroursodeoxycholate (TUDCA) is a hydrophilic bile acid. Tauroursodeoxycholate as a cytoprotective agent improves liver function and can prevent hepatocellular carcinoma by reducing ER stress and apoptosis. Tauroursodeoxycholate significantly reduces expression of apoptosis molecules, such as caspase-3, caspase-12, C/EBP homologous protein, c-Jun N-terminal kinase (JNK), activating transcription factor 4 (ATF4), X-box binding protein (XBP), and eukaryotic initiation factor 2α (eIF2α) in Ang II induced ApoE-/- mice (p<0.05). Tauroursodeoxycholate reduces Angiotensin (Ang) II induced abdominal aortic aneurysm (AAA) formation in ApoE-/- mice. Tauroursodeoxycholate is used at a dose of 0.5 g/kg/day in treating Ang II induced ApoE-/- mice (ER stress inhibitor group). Systolic blood pressure (141.3±5.6 mmHg vs 145.9±8.9 mmHg; p>0.05) and total cholesterol levels (663.6±88.7 mg/dL vs 655.7±65.4 mg/dL; p>0 .05) do not differ between the AAA model group and Tauroursodeoxycholate group. In addition, maximum aortic diameter is significantly smaller in those in Tauroursodeoxycholate group compared with those in the AAA model group (0.95±0.03 mm vs 1.79±0.04 mm; p<0.05). AAA lesion areas are also smaller in those in Tauroursodeoxycholate group than in those in the AAA model group (0.37±0.03 mm2 vs 1.51±0.06 mm2; p<0.05)[2]. References: | |||||

Sodium tauroursodeoxycholate (TUDC) shows therapeutic effect on cholestasis [1, 2]. In human erythrocytes, it inhibited 2’,7’-bis-(carboxypropyl)-5(6)-carboxyfluorescein (BCPCF) efflux induced by bile salts with an IC50 value of 560 µM [3].
Cholestasis is the syndrome resulted from the impairment of the formation of bile, a vital function [4].
cVA-of-CLF means the canalicular vacuolar accumulation of cholyllysylfluorescein [1]. cVA of CLF is a parameter to indicate overall biliary secretion [5]. Incubation with 17βEG dose-dependently decreased the cVA-of-CLF in cells. 17βEG at a concentration of 50 µM decreased cVA-of-CLF by 40%. The simultaneous incubation with TUDC and 17βEG improved the decreased cVA by 24%. The simultaneous incubation with SAMe and 17βEG improved the decreased cVA by 18%. The simultaneous incubation with TUDC, SAMe and 17βEG improved the decreased cVA by 28%. But the effect of TUDC + SAMe was not significantly greater than the effect of either protectant alone [1].
In rats, intrahepatic cholestasis was induced by the administration of phalloidin at an i.p. dose of 500 µg/kg for 7 days. In these treated rats, bile flow was decreased, and activities of glutamic pyruvic transaminase, leucine aminopeptidase, serum alkaline phosphatase, and concentrations of bile acid, phospholipid and cholesterol were increased. But these effects were significantly suppressed by tauroursodeoxycholate. In these rats, excretion rates of biliary cholesterol and phospholipid were significantly improved by tauroursodeoxycholate [2].
