1 Taurine-deficient diet up-regulated cystathionine beta-synthase monoallele in hemizygous cystathionine beta-synthase knockout mice. Taurine cystathionine beta-synthase Mus musculus
2 Taurine-deficient diet up-regulated cystathionine beta-synthase monoallele in hemizygous cystathionine beta-synthase knockout mice. Taurine cystathionine beta-synthase Mus musculus
3 Reduced CBS activity could decrease cysteine and taurine biosyntheses (metabolites of homocysteine degradation) and lead to less taurocholic acid production with a resultant increased cholesterol content. Taurine cystathionine beta-synthase Mus musculus
4 We hypothesized that a deficiency in CBS genetic material and enzyme activity would reduce taurine synthesis, which would lead to an elevated cholesterol concentration. Taurine cystathionine beta-synthase Mus musculus
5 Three important findings were a differential sex response of CBS mRNA to feeding the vitamin B(6) diet; CBS (+/-) mice had a significantly lower plasma cholesterol concentration, contrary to what was anticipated; and during feeding, the taurine- and cysteine-deficient diet, CBS mRNA levels in CBS (+/-) mice were reduced only 13% rather than the expected 50%. Taurine cystathionine beta-synthase Mus musculus

8 We conclude that the remaining CBS monoallele is up-regulated in mice when fed a taurine-deficient diet to produce additional CBS mRNA. Taurine cystathionine beta-synthase Mus musculus
9 We conclude that the remaining CBS monoallele is up-regulated in mice when fed a taurine-deficient diet to produce additional CBS mRNA. Taurine cystathionine beta-synthase Mus musculus
