Taurine concentration decreases rapidly in the tissues and physiological fluids of kittens fed a diet of partially purified casein which lacks taurine. We have studied the subcellular distribution in cerebrum of taurine and [35S]taurine administered intravenously to these animals. The taurine concentration of all the fractions isolated from the cerebrum of taurine-deficient kittens was approximately sevenfold less than that observed in the fractions of cerebrum isolated from control kittens. The [35S]taurine was approximately twofold greater in all the brain fractions isolated from the taurine-deficient kittens compared with those isolated from the control kittens. The percent distributions of taurine and [35S]taurine in the fractions isolated from the cerebrum of control and deficient kittens were identical. Thus, in the face of a severe diet-induced deficiency of taurine in kitten brain, there appears to be no conservation of taurine by any particular subcellular pool of taurine. These studies provide no evidence for differences in compartmentation of taurine in cerebrum of taurine-deficient kittens compared with control kittens.
