Hoechst 33342 apoptosis

NettetHoechst 33342-induced apoptosis is associated with disruption of TATA box binding protein/TATA box complexes, replication protein A/single-stranded DNA complexes, topoisomerase I/DNA cleavable complexes and with an increased intracellular concentration of E2F-1 transcription factor and nitric oxide concentration. NettetSimilarly, among the three cell lines, MTDH/AEG-1 siRNA had the most significant influence in the T24 cells. The results of Hoechst 33342 and PI double fluorescent staining indicated a clear increase in apoptosis after transfection with MTDH/AEG-1 siRNA, especially at 96 hours (Figures 10D–10F and 11).
