To better understand the increased sensitivity of proliferating intestinal epithelial cells to topoisomerase I (topo I) poisons, we examined differentiation of a human intestinal cell line (Caco-2) in the presence of camptothecin (CPT) and its analogs irinotecan (CPT-11) and topotecan (TPT). The pro
Chromosomes with Ag staining that varies from one metaphase to the other can be distinguished from those with an Ag-staining that is the same in all metaphases. The intercellular variation of an Ag-NOR can be attributed to many different factors. Whatever the importance of technical factors, they do
Background. Nucleolar organizer regions (NORs) are loops of ribosomal DNA that occur in nucleoli and that transcribe to ribosomal RNA. NORs have been identified by means of the Ag-NOR technique in routinely processed tissues, and were found to be of discriminative value between some types of benign
