Glutathione-Dependent Bioactivation and Renal Toxicity of Xenobioticsns (Meister 1988, 1992). Due to the nucleophilicity of the sulfur atom and the antioxidant properties of glutathione, this tripeptide is an important factor in the detoxication of xenobiotics and oxidants (Boyland and Chasseaud 1969). The formation of glutathione .-conjugates from xenobiotics and th

Two-Dimensional Polyacrylamide Gel Electrophoresis of Cancer-Associated Proteins years considerable effort has been made to define the genetic events involved in the etiology of cancer development. Indeed, molecular genetics has been highly successful in the demonstration that development of certain forms of human cancers, in particular, colorectal, lung, and breast, may arise

DNA hypomethylation is one of the possible causes and one of the consequences of mammalian neoplasia and also occurs in cultured cells after treatment with certain carcinogenic drugs (Spruck et al. 1993). Changes in DNA

Among these extragenomic cellular components, the histories and the proteins of the nuclear matrix, consisting mainly of the nuclear pore complex and the nuclear lamins, are
