Disease relevance of Pyronine

 

High impact information on Pyronine

  • In determining whether Bcl-2 and Bcl-x(L) act in G(0) or G(1), forward scatter and pyronin Y fluorescence measurements indicated that Bcl-2 and Bcl-x(L) cells arrested more effectively in G(0) than controls, and were delayed in G(0)-G(1) transition [4].
  • DNA-bound Hoechst 33342 (blue), protein-fluorescein isothiocyanate (green), and RNA-bound pyronin Y (red) fluorescence measurements were correlated as each stained cell intersected three spatially separated laser beams [5].
  • Interestingly, the G(0) cells defined by their low levels of Hoechst 33342 and Pyronin Y staining, and reduced Ki67 and cyclin D expression (representing 21% of the cultured CB population) include some mature erythroid CFCs but very few primitive CFCs, LTC-ICs, or repopulating cells [6].
  • To test the hypothesis that primitive LTHC-ICs would reenter a state of relative quiescence after in vitro division, BM CD34(+) cells proliferating in ex vivo cultures were identified from their quiescent counterparts by a relative loss of membrane intercalating dye PKH2, and were further fractionated with Hst and PY [7].
  • Reticulocytes in fixed human blood samples were stained for RNA with the fluorescent dye pyronin Y and measured by flow cytometry [8].
