Disease relevance of Abcg2


High impact information on Abcg2

  • Therefore, Bcrp1 has an important role in extruding glucuronide and sulfate conjugates formed in enterocytes into the intestinal lumen, whereas Mrp2 is responsible for the efflux of some glucuronide conjugates [1].
  • The intestinal lumen of EHBRs and Bcrp1 (-/-) mice was perfused with medium containing 4-methylumbelliferone (4MU) and E3040 [6-hydroxy-5,7-dimethyl-2-methylamino-4-(3-pyridilmethyl) benzothiazole] to determine the efflux of metabolites into the outflow [1].
  • Immunocytochemical analysis demonstrates specificity of expression of Sox1, ABCG2/Bcrp1, and shows that nucleostemin labels both progenitor and stem cell populations [2].
