  • Title: The effect of taurine depletion with guanidinoethanesulfonate on bile acid metabolism in the rat.
    Author: De la Rosa J, Stipanuk MH.
    Journal: Life Sci; 1985 Apr 08; 36(14):1347-51. PubMed ID: 3982216.
    Abstract:
    Administration of guanidinoethanesulfonate (GES) to male rats for 5 weeks resulted in a 90% decrease in the hepatic taurine concentration. This depletion of hepatic taurine was associated with a 570% increase in the concentration of glycine-conjugated bile acids, a 30% decrease in the concentration of taurine-conjugated bile acids, and an increase in the ratio of glycine- to taurine-conjugated bile acids from 0.046 to 0.45. The total concentration of bile salts in the bile and the turnover of cholic acid were not affected by administration of GES. The data indicate that the taurine-depleted rat conserves taurine to some extent by using glycine instead of taurine for bile salt synthesis but not by decreasing the daily fractional turnover of bile acids.
