Sp1 Regulates Chromatin Looping between an Intronic Enhancer and Distal Promoter of the Human Heme Oxygenase-1 Gene in Renal Cells
30 Mar 2010
Abstract excerpt
HO-1 (heme oxygenase-1) is an inducible microsomal enzyme that catalyzes the degradation of pro-oxidant heme. The goal of this study was to characterize a minimal enhancer region within the human HO-1 gene and delineate its role in modulating HO-1 expression by participation with its promoter elements in renal epithelial cells. Deletion analysis and site-directed mutagenesis identified a 220-bp minimal enhancer...
