Effects of Hoechst 33342 on C2C12 and PC12 cell differentiation.
Accumulative evidence demonstrates that normal as well as cancer stem cells can be identified as a side population following Hoechst 33342 staining and flow cytometric analysis. This popular method is based on the ability of stem cells to efflux this fluorescent vital dye. We demonstrate that Hoechst 33342 can affect cell differentiation, suggesting potential complications in the interpretation...
متن کاملLabeling nuclear DNA with hoechst 33342.
A number of fluorescent stains are available that label DNA and allow easy visualization of the nucleus in interphase cells and chromosomes in mitotic cells. One advantage of Hoechst 33342 is that it is membrane permeant and, thus, can stain live cells. Hoechst 33342 binds to adenine-thymine-rich regions of DNA in the minor groove. On binding to DNA, the fluorescence greatly increases. This pro...
متن کاملMechanism of Hoechst 33342-induced apoptosis in BC3H-1 myocytes.
Hoechst 33342, a bisbenzimidazole dye, binds to adenine/thymine rich regions in the minor groove of deoxyribonucleic acid (DNA). This dye induces apoptosis in BC3H-1 myocytes. The mechanism of Hoechst 33342-induced apoptosis was investigated. Inhibitors of ribonucleic acid (RNA) synthesis, protein synthesis, and serine or cysteine proteases failed to prevent BC3H-1 myocyte death induced by Hoec...
متن کاملFlow cytometric analysis of marine bacteria with hoechst 33342.
We investigated the accuracy and precision of flow cytometric (FCM) estimates of bacterial abundances using 4', 6-diamidino-2-phenylindole (DAPI) and Hoechst 33342 (HO342, a bisbenzamide derivative) on paraformaldehyde-fixed seawater samples collected from two stations near Oahu, Hawaii. The accuracy of FCM estimates was assessed against direct counts by using epifluorescence microscopy. DAPI a...
متن کاملHeterogeneity in the radiosensitizing effects of the DNA ligand hoechst-33342 in human tumor cell lines.
The AT specific minor grove DNA binding ligands bisbenzimidazole derivatives like hoechst-33342 and hoechst-33258 which scavenge free radicals and stabilize macromolecular structure have been shown to afford radioprotection by reducing the induction of DNA damage. However, their ability to inhibit topoisomerases I & II, which play important roles in damage response pathways including DNA repair...
