原始语种摘要: Abstract(#br)The use of surrogate end‐point biomarkers could help in the development of chemopreventive agents. To define potential surrogate end‐point biomarkers, the ability of budesonide to decrease mRNA expression of the insulin‐like growth factor‐2 ( Igf‐II ) and c‐ myc genes and to cause the remethylation of the genes was investigated in lung tumors. Lung tumors were induced in female strain A mice by administering i.p. 16 mg/kg vinyl carbamate for 2 consecutive wk or by a single dose of 100 mg/kg benzo[ a ]pyrene (B[ a ]P). Thirty‐four weeks later, the mice given vinyl carbamate received budesonide (0.6 or 2.4 mg/kg diet) for 7 d and then were killed. Mice were killed 24 wk after administration of B[ a ]P. The mRNA expression of the Igf‐II and c‐ myc genes was increased in lung...
