Detection of P glycoprotein activity on normal and leukemic CD34+ cells.

Abstract:

:Rhodamine 123 is transported by the transmembrane efflux pump P glycoprotein (Pgp). We used this fluorescent dye to study multidrug resistance (MDR) activity in normal and leukemic CD34+ cells. These immature cells had a high degree of MDR activity. Among leukemic cells, CD34+ leukemias had significantly higher MDR activity as compared to CD34- leukemias. Heterogeneous results in cell subpopulations, however, indicate that prognosis should be interpreted in the light of MDR analysis.

  • Glycosylation interference on RhoA activation: focus on G-CSF.

    abstract::Glycosylation of cytokines appears to be responsible for several differences in their activity, and focusing on G-CSF, several divergences between the non-glycosylated G-CSF, Filgrastim, and the glycosylated G-CSF, Lenograstim, have been reported. To verify the role of G-CSF glycosylation in mediating these difference...
