Acute kidney injury (AKI), defined as the rapid loss of kidney function, is often seen in the setting of multiple organ failure in critically ill patients. Lack of established therapeutic approaches to overcome AKI has lead to unacceptably high incidence of morbidity and mortality in these patients. The molecular mechanisms that lead to AKI often have oxidative stress as a common pathogenic event. The kidney responds by prompt induction of its own anti-oxidant machinery including the highly inducible, anti-inflammatory and anti-apoptotic gene-heme oxygenase-1 (HO-1). This microsomal enzyme degrades pro-oxidant heme, which is released from heme proteins. The cytoprotective properties of …

Heme oxygenase-1 (HO-1) is a critical enzyme catalyzing the degradation of heme and generating carbon monoxide, iron, and biliverdin. In addition to heme degradation, HO-1 expression is known to protect against various cellular insults and disease states including acute kidney injury, atherosclerosis, vascular restenosis, and others. Human HO-1 gene expression is tightly regulated at the level of transcription. The main goal of this study is to explore the transcriptional regulation of the human HO-1 gene in renal epithelial cells. Chromosome Conformation Capture (3C) demonstrates that multiple regulatory regions within the HO-1 promoter and enhancer regions are physically interacting with each …
