Isolated rat-liver nuclei were incubated with a series of membrane-permeable metal-ion-complexing agents and examined for DNA damage. Of the reagents tested, only 1,10-phenanthroline (OP) and neocuproine (NC) were found to induce DNA fragmentation. Agarose-gel electrophoresis of the DNA fragments generated in the presence of OP revealed internucleosomal cleavage, which is widely considered to b...
Serum-free PC12 cell cultures have been used to study the mechanisms of neuronal death after neurotrophic factor deprivation. We previously reported that PC12 cells undergo "apoptotic" internucleosomal DNA cleavage after withdrawal of trophic support. Here, we have used a sensitive method to detect PC12 cell DNA fragmentation within three hrs of serum removal and have exploited this assay to ex...
