Biological context of B4galnt2

 

Anatomical context of B4galnt2

  • Following treatment with PhIP, there was no difference in the number of Dlb-1 locus mutations between the proximal and distal ends of the small intestine in uninduced animals, indicating that the bile duct is unlikely to be responsible for transport of mutation inducing metabolites of PhIP to the small intestine [10].
  • Previous studies have shown that although this compound produces multiple tumors in the colons in most individuals of every species tested, it is, at best, marginally mutagenic in the bone marrow (micronuclei) and small intestine (Dlb-1 mutations) [11].
  • Chromosome aberrations induced in lymphocytes and Dlb-1 mutations induced in the small intestine were measured after daily doses of 0.64, 1.85 or 5.5 cGy 137Cs gamma rays administered for 21, 42 or 63 days [12].
  • The lacI assay (Big Blue Mouse assay) is not as sensitive to some types of mutation as is Dlb-1 but was used in the colonic epithelium [13].
 

Associations of B4galnt2 with chemical compounds

  • Chronic administration of 1,2-dimethylhydrazine (20 mg/kg/week s.c. for 10 weeks) induced Dlb-1 mutants, whereas administration of a single dose did not [14].
  • Similarly, chronic dimethylnitrosamine treatment p.o. (0.001% in drinking water for 8 weeks) induced Dlb-1 mutants, but acute administration did not [14].
 

Other interactions of B4galnt2

  • Studies in congenic Ahr-non-responsive versus Ahr-responsive mice indicated that induction of CYP1A1 was associated with increased numbers of Dlb-1 mutations [15].
