Multiple GF-1 binding sites flank the erythroid specific transcription unit of the human carbonic anhydrase I gene
AbstractSix potential GF-1 sites which bind an erythroid factor are present in the 5' and 3' regions flanking the erythroid-speciflc transcription unit of the human carbonic anhydrase 1 (HCAI) gene. When two of these sites are placed upstream of a minimal eukaryotic promoter they confer upregulated expression in erythroid over non-erythroid cells. The presence of the erythroid factor in TPA-treated HEL cells in which the level of HCAI transcript has greatly decreased and in non-HCAI-expressing K562 cells suggests that in these cases the presence of the factor is not sufficient for HCAI expression

Isolation of flow and nonflow correlations by two- and four-particle cumulant measurements of azimuthal harmonics in √sNN = 200 GeV Au+Au collisions
A data-driven method was applied to Au+Au collisions at √sNN = 200 GeV made with the STAR detector at RHIC to isolate pseudorapidity distance η-dependent and η-independent correlations by using two- and four-particle azimuthal cumulant measurements. We identified a η-independent component of the correlation, which is dominated by anisotropic flow and flow fluctuations. It was also found to be independent of η within the measured range of pseudorapidity |η| 0.7
