Protocol

Cell experiment:

Cell viability and proliferation are measured using Ez-Cytox. VSMCs (5×103 cells) are seeded onto 96-well plates in Smooth Muscle Cell Growth Medium 2 (SMCGM2) and cultured. After serum starvation, Tauroursodeoxycholate (0, 50, 100, and 200 μM) is added to the hVSMCs, with or without 1,2-bis(o-aminophenoxy) ethane-N,N,N′,N′-tetraacetic acid tetra(acetoxymethyl) ester (BAPTA, 10 μM) and 7-hydroxystaurosporine (H7, 10 μM) and cultured for 24 h. To assess the effect of Tauroursodeoxycholate on the PDGF-stimulated hVSMC proliferation, hVSMCs are seeded onto 96-well plates and cultured. After serum starvation, Tauroursodeoxycholate (0, 50, 100, and 200 μM) is added to the hVSMCs, with or without PDGF-BB (50 ng/mL) and cultured. After addition of 10 μL of Ez-Cytox into each well, cell viability is evaluated by measuring the optical density at 450 nm[1].

Animal experiment:

Rats[1]Sprague-Dawley rats are anaesthetized with a combined anaesthetic (Ketamine, 70 mg/kg; Xylazine, 7 mg/kg ip). Tauroursodeoxycholate is administered orally once a day, in different concentrations (i.e. vehicle, 10, 50, and 100 mg/kg) for 2 weeks. The carotid arteries are fixed by perfusion with 4% formaldehyde, then the tissues are embedded in paraffin, and sections (8 μm) are stained with H&E[1]. Mice[2]Thirty ApoE-/- C57BL/6 male mice aged 8 weeks are randomly divided into three groups (n=10 in each group): (i) sham operated and injected with physiologic (0.9%) saline as vehicle (normal: group); (ii) mini-osmotic pumps are implanted subcutaneously into the right flank of ApoE-/- mice to release Ang II (1000 ng/kg/min) over the course of 28 days (AAA model group); (iii) AAA model mice treated with Tauroursodeoxycholate daily for 4 weeks at a dosage of 0.5 g/kg/day in drinking water (Tauroursodeoxycholate group). Mice are sacrificed after 28 days of Ang II infusion[2].

Background

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].
