Cytoprotective Effects of Heme Oxygenase in Acute Renal Failure

Akagi, Reiko, Takahashi, Toru, Sassa, Shigeru·2005·Contributions to Nephrology

Abstract

Following ischemia, superoxide is produced during the reperfusion phase in various organs. In renal pathophysiology, excess of free heme, which is released from hemeproteins under these conditions, catalyzes the formation of further reactive oxygen species to accelerate cellular injuries. There is accumulating evidence suggesting that transcriptional activation of heme oxygenase (HO)-1, the rate-limiting enzyme in heme degradation as well as the 32-kDa heat shock protein, participates in the defense against oxidative tissue injuries. Ischemia followed by reperfusion of the rat kidney accompanies significant induction of HO-1 mRNA, protein and enzyme activity, which is in part mediated through a rapid and transient increase in microsomal heme concentration. Inhibition of HO activity by tin mesoporphyrin results in a sustained and enhanced increase in microsomal heme content, and significantly exacerbates renal function. In contrast, SnCl2 treatment, which specifically induces HO-1 mRNA and protein in the proximal tubular epithelial cells, prevents the ischemia-reperfusion-mediated increase in microsomal heme concentration, and ameliorates the ischemic renal injury. In addition to these findings, recent evidence on the role of HO-1 in the kidney pathophysiology is summarized, with a particular emphasis on its protective role in the ischemic acute renal failure.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
