7、 a cultured human hepatoblastoma cell line, HepG2 3. Chenodeoxycholic acid-induced Isc is inhibited (67%) by Bumetanide, BaCl2, and the cystic fibrosistransmembrane conductance regulator (CFTR) inhibitor CFTRinh-172.

9、e construct containing -1.65-kb GSTA2 promoter, whichcontains C/EBP response element (pGL-1651). Chenodeoxycholic acid treatment activates AMP-activatedprotein kinase (AMPK), which leads to extracellular signal-regulated kinase 1/2 (ERK1/2) activation, asevidenced by the results of experiments using

10、 a dominant-negative mutant of AMPK and chemical inhibitor5.PROTOCOLKinase Assay 1 Briefly, transfected HEK-293 cells, incubated in charcoal-treated Dulbeccos modified Eagles medium for 24h, are washed once with Hanks solution and resuspended in a buffer containing 100 mM NaCl, 1 mM MgCl2,1 mM EDTA,

11、 1 mM EGTA, 250 mMsucrose, 20 mM Tris-HCl, pH 7.4. Cells are lysed by freezing in liquidnitrogen. Dehydrogenase activity is measured in a final volume of 20 L containing the appropriateconcentration of bile acid, 30 nCi of 3Hcortisol, and unlabeled cortisol to a final concentrations of 50 nM.The rea

12、ction is started by mixing cell lysate with the reaction mixture. Alternatively, endoplasmic reticulummicrosomes are prepared from transfected HEK-293 cells and incubated with reaction mixture containingvarious concentrations of cortisol and CDCA. Incubation proceeded for 20 min, and the conversion

13、of cortisolto cortisone is determined by thin layer chromatography (TLC). Because of the inaccuracy of the TLC methodat low conversion rates and the end-product inhibition of 11HSD2 at conversion rates higher than 60-70%,only conversion rates between 10 and 60% are considered for calculation. The in

15、Cell Assay 1 The cell viability is analyzed by incubating transfected HEK-293 cells and CHO cells for 1 h with thecorresponding concentration of bile acid and staining with trypan blue. The toxicity of bile acids is analyzedusing the tetrazolium salt MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltet
