Abstract

The effect of a single oral dose of 4-ethylsulfonylnaphthalene-1 -sulfonamide, 2-acetylaminofluorene, and 3-aminodibenzofuran on DNA, RNA, and protein synthesis in the urinary bladder and liver of the mouse has been investigated. Each chemical stimulated RNA and DNA synthesis in the bladder, but the magnitude and timing of the response was different in each case. Administration of 4-ethylsulfonyl-naphthalene-1 -sulfonamide in the diet produced an increase in DNA synthesis in the mouse bladder which lasted for 4 weeks, whereas with 2-acetylaminofluorene, increased DNA synthesis occurred only during the first week. The effect of 4-ethylsulfonyl-naphthalene-l -sulfonamide on nucleic acid synthesis was specific for the bladder, whereas 2-acetylaminofluorene stimulated both RNA and DNA synthesis in the liver and 3-aminodibenzofuran induced a small increase in DNA synthesis in male, but not in female, mouse liver.
