Ki-67 as a cell proliferation marker is tightly associated with maintenance and regulation of the cell division. To understand the mechanism of Ki-67 gene expression and regulation, we first cloned 5′-flanking region and identified the Ki-67 core promoter. The deletion analysis and the dual luciferase reporter assay were used to locate the Ki-67 core promoter from −223 to +12 nt relative to the transcriptional...
Ki-67 plays a crucial role in cell proliferation as well as maintenance or regulation of cell division. The mechanism governing the Ki-67 gene expression remains unknown. Thus, we cloned the core promoter of the human Ki-67 gene and further investigated its transcriptional regulation. The putative Sp1 binding sites were confirmed by electrophoretic mobility shift assay together with an anti-Sp1 antibody-mediated...
