Analysis by high-resolution two-dimensional electrophoresis of differentiation-dependent alterations in cytosolic protein pattern of HL-60 leukemic cells
No full textHL-60 leukemic cells were differentiated along the neutrophilic pathway with retinoic acid (RA) or along the monocytic pathway with 1,25-dihydroxyvitamin D3 (1,25(OH)2D3). Using a high-resolution two-dimensional electrophoresis technique and subsequent silver staining, differentiation-dependent changes in cytosolic protein pattern of HL-60 cells were analysed and were compared with the cytosolic protein pattern of human neutrophils. The amount of 64 and 50 out of a total of 632 proteins studied was increased or decreased in RA- and 1,25(OH)2D3-differentiated HL-60 cells, respectively, in comparison to undifferentiated HL-60 cells. Thirty-three of these proteins were similarly altered in RA- and 1,25(OH)2D3-differentiated HL-60 cells. Twenty-two and 25 of the proteins altered in amount in RA- or 1,25(OH)2D3-differentiated HL-60 cells versus undifferentiated HL-60 cells were similarly altered in human neutrophils in comparison to undifferentiated HL-60 cells. Seven and 10 of the proteins altered in amount in RA- or 1,25(OH)2D3-differentiated HL-60 cells had specific equivalents in neutrophil cytosol. Our results show (i) that neutrophilic and monocytic differentiation is associated with decreases and increases in amount of cytosolic proteins; (ii) that both differentiation processes share a common set of alterations; and (iii) are associated with specific alterations in protein amount

Experimental Check of Deceleration of Neutral Beam-Injected Energetic Ions in the HL-2A Tokamak
Full text linkShort pulses of a deuterium neutral beam (NB) with a duration of less than ? 5 ms were co-injected into magnetohydrodynamic (MHD)-quiescent ohmic deuterium plasmas of the HL-2A tokamak to study the variation of the slowing-down time in two different electron temperature environments. Analyses were made for the decay rate of D-D neutrons produced by beam-plasma interaction following NB turn-off, i.e., experimentally observed neutron decay rates were compared with those predicted by a classical slowing-down model. The results suggest the beam ions decelerate without significant loss in the HL-2A tokamak in round terms. When the critical energy for beam ions is higher than the beam injection energy, it seems that a small fraction of the beam ions is lost.journal articl
