## Abstract We previously reported a separation, on an organomercurial column, of transcriptionally inactive nucleosomes (class 1) from those containing active gene sequences (classes 2 and 3). In this paper, we analyzed nucleosomal damage caused by exposure of HeLa S3 cells in suspension culture t

## Abstract Numerous prospective and retrospective studies have clearly demonstrated a doseβrelated increased lung cancer risk associated with cigarette smoking, with evidence also for a genetic component to risk. In this study, using the twoβstage clonal expansion stochastic model framework, for t
## Abstract Copper is an essential trace element involved, among other functions, in enzymatic antioxidative defense systems. However, nonprotein bound copper ions have been shown to generate reactive oxygen species. To gain insight into the discrepancy between the protective properties of copper o
In breast and colon adenocarcinomas methylation patterns at CCGG sites of several loci located on the short arm of chromosome 11 were determined by Southern blot analysis. Results obtained indicate that all tumor samples (20/20) exhibit DNA methylation changes when compared to their normal counterpa
