title: Qualitative alterations in plasma esterases in BALB/c mice following the administration of diethylnitrosamine.
abstract: Selected non-specific plasma esterases in female BALB/c mice, separated by polyacrylamide gel electrophoresis, were qualitatively altered following treatment of the mice with diethylnitrosamine (DEN). These alterations include a decreased preference for naphthyl butyrate as a substrate relative to naphthyl acetate; decreased sensitivity to enhancement by divalent cations such as Ca2+, Mg2+, and Mn2; and an increased sensitivity to inhibition by eserine. All esterase species affected were also quantitatively altered and some were testosterone-dependent.
