Abstract
The incidence of kidney disease is rising, constituting a significant burden on the healthcare system and making identification of new therapeutic targets increasingly urgent. The heme oxygenase (HO) system performs an important function in the regulation of oxidative stress and inflammation and, via these mechanisms, is thought to play a role in the prevention of non-specific injuries following acute renal failure or resulting from chronic kidney disease. The expression of HO-1 is strongly inducible by a wide range of stimuli in the kidney, consequent to the kidney's filtration role which means HO-1 is exposed to a wide range of endogenous and exogenous molecules, and it has been shown to be protective in a variety of nephropathological animal models. Interestingly, the positive effect of HO-1 occurs in both hemolysis- and rhabdomyolysis-dominated diseases, where the kidney is extensively exposed to heme (a major HO-1 inducer), as well as in non-heme-dependent diseases such as hypertension, diabetic nephropathy or progression to end-stage renal disease. This highlights the complexity of HO-1's functions, which is also illustrated by the fact that, despite the abundance of preclinical data, no drug targeting HO-1 has so far been translated into clinical use. The objective of this review is to assess current knowledge relating HO-1's role in the kidney and its potential interest as a nephroprotection agent. The potential therapeutic openings will be presented, in particular through the identification of clinical trials targeting this enzyme or its products.

Am J Physiol Lung Cell Mol Physiol 2018; 315:L545-L552. [PMID: 30024305 PMCID: PMC6230877 DOI: 10.1152/ajplung.00214.2018] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2018] [Revised: 07/13/2018] [Accepted: 07/16/2018] [Indexed: 11/22/2022] Open
Abstract
Thioredoxin reductase-1 (TXNRD1) inhibition effectively activates nuclear factor (erythroid-derived 2)-like 2 (Nrf2) responses and attenuates lung injury in acute respiratory distress syndrome (ARDS) and bronchopulmonary dysplasia (BPD) models. Upon TXNRD1 inhibition, heme oxygenase-1 (HO-1) is disproportionally increased compared with Nrf2 target NADPH quinone oxidoreductase-1 (Nqo1). HO-1 has been investigated as a potential therapeutic target in both ARDS and BPD. TXNRD1 is predominantly expressed in airway epithelial cells; however, the mechanism of HO-1 induction by TXNRD1 inhibitors is unknown. We tested the hypothesis that TXNRD1 inhibition induces HO-1 via Nrf2-dependent mechanisms. Wild-type (WT), Nrf2KO1.3, and Nrf2KO2.2 cells were morphologically indistinguishable, indicating that Nrf2 can be deleted from murine-transformed club cells (mtCCs) using CRISPR/Cas9 gene editing. Hemin, a Nrf2-independent HO-1-inducing agent, significantly increased HO-1 expression in WT, Nrf2KO1.3, and Nrf2KO2.2. Auranofin (AFN) (0.5 µM) inhibited TXNRD1 activity by 50% and increased Nqo1 and Hmox1 mRNA levels by 6- and 24-fold, respectively, in WT cells. Despite similar levels of TXNRD1 inhibition, Nqo1 mRNA levels were not different between control and AFN-treated Nrf2KO1.3 and Nrf2KO2.2. AFN slightly increased Hmox1 mRNA levels in Nrf2KO1.3 and Nrf2KO2.2 cells compared with controls. AFN failed to increase HO-1 protein in Nrf2KO1.3 and Nrf2KO2.2 compared with a 36-fold increase in WT mtCCs. Our data indicate that Nrf2 is the primary mechanism by which TXNRD1 inhibitors increase HO-1 in lung epithelia. Future studies will use ARDS and BPD models to define the role of HO-1 in attenuation of lung injury by TXNRD1 inhibitors.

Abstract
Sex and age influence susceptibility to acute kidney injury (AKI), with young females exhibiting lowest incidence. In these studies, we investigated mechanisms which may underlie the sex/age-based dissimilarities. Cisplatin (Cp)-induced AKI resulted in morphological evidence of injury in all groups. A minimal rise in plasma creatinine (PCr) was seen in Young Females, whereas in Aged Females, PCr rose precipitously. Relative to Young Males, Aged Males showed significantly, but temporally, comparably elevated PCr. Notably, Aged Females showed significantly greater mortality, whereas Young Females exhibited none. Tissue KIM-1 and plasma NGAL were significantly lower in Young Females than all others. IGFBP7 levels were modestly increased in both Young groups. IGFBP7 levels in Aged Females were significantly elevated at baseline relative to Aged Males, and increased linearly through day 3, when these levels were comparable in both Aged groups. Plasma cytokine levels similarly showed a pattern of protective effects preferentially in Young Females. Expression of the drug transporter MATE2 did not explain the sex/age distinctions. Heme oxygenase-1 (HO-1) levels (~28-kDa species) showed elevation at day 1 in all groups with highest levels seen in Young Males. Exclusively in Young Females, these levels returned to baseline on day 3, suggestive of a more efficient recovery. In aggregate, we demonstrate, for the first time, a distinctive pattern of response to AKI in Young Females relative to males which appears to be significantly altered in aging. These distinctions may offer novel targets to exploit therapeutically in both females and males in the treatment of AKI.

Heme oxygenase-1 mediated memorial and revivable protective effect of ischemic preconditioning on brain injury. CNS Neurosci Ther 2013; 19:963-8.

Abstract
AIMS Ischemic preconditioning (IPC) has short-term benefits for stroke patients. However, if IPC protective effect is memorial and the role of the intracellular protective protein heme oxygenase-1 (HO-1) is not known. METHODS Ischemic preconditioning and the corresponding sham control were achieved by blocking the blood flow of the left internal carotid artery for 20 min and 2 second, respectively, in rats. Both IPC and sham-operated animals were divided into three groups and treated with PBS, the HO-1 inducer hemin, and the HO-1 inhibitor Znpp. Three weeks after IPC, brain ischemia-reperfusion injury was achieved by left middle cerebral artery obstruction for 45 min followed by 24-h reperfusion. RESULTS 2,3,5-triphenyltetrazolium chloride staining and neurological dysfunction scoring showed IPC significantly reduced brain infarct area and improved neurological function occurred 3 weeks after IPC. Hemin treatment promoted whereas ZnPP blocked the benefits of IPC. Immunohistochemical analysis and Western blotting showed that the expression of HO-1 was higher in the border zone than in the necrotic core zone. The memorial IPC protection is independent of adenosine receptor A1R and A2aR expressions. CONCLUSIONS We found for the first time that the protective effect of IPC can be remembered to protect brain injury occurred after acute response disappear. The results indicate that interventional treatment can achieve protective effect for future cerebral injury not only through interventional treatment itself but also through the memorial and revivable IPC, eliminating the concern that temporary ischemia caused by interventional treatment may leave harmful effect in the brain.

Abstract
OBJECTIVE To determine if the magnitude of the acute injury response to shock-wave lithotripsy (SWL) depends on the number of SWs delivered to the kidney, as SWL causes acute renal oxidative stress and inflammation which are most severe in the portion of the kidney within the focal zone of the lithotripter. MATERIALS AND METHODS Pigs (7-8 weeks old) received 500, 1000 or 2000 SWs at 24 kV from a lithotripter to the lower pole calyx of one kidney. At 4 h after treatment the kidneys were removed, and samples of cortex and medulla were frozen for analysis of the cytokine, interleukin-6, and for the stress response protein, heme oxygenase-1 (HO-1). Urine samples taken before and after treatment were analysed for the inflammatory cytokine, tumour necrosis factor-α. For comparison, we included previously published cytokine data from pigs exposed to sham treatment. RESULTS Treatment with either 1000 or 2000 SWs caused a significant induction of HO-1 in the renal medulla within the focal zone of the lithotripter (F2, 1000 SWs, P < 0.05; 2000 SWs, P < 0.001). Interleukin-6 was also significantly elevated in the renal medulla of the pigs that received either 1000 or 2000 SWs (P < 0.05 and <0.001, respectively). Linear dose-response modelling showed a significant correlation between the HO-1 and interleukin-6 responses with SW dose (P < 0.001). Urinary excretion of tumour necrosis factor-α from the lithotripsy-treated kidney increased only for pigs that received 2000 SWs (P < 0.05). CONCLUSION The magnitude of renal oxidative stress and inflammatory response in the medulla increased with the number of SWs. However, it is not known if the HO-1 response is beneficial or deleterious; determining that will inform us whether SWL-induced renal injury can be assessed by quantifying markers of oxidative stress and inflammation.

Abstract
Hypoxia and the Net ternary complex factor (TCF) regulate similar processes (angiogenesis, wound healing, and cellular migration) and genes (PAI-1, c-fos, erg-1, NOS-2, HO-1, and vascular endothelial growth factor genes), suggesting that they are involved in related pathways. We show here that hypoxia regulates Net differently from the other TCFs and that Net plays a role in the hypoxic response in vivo in mice and in cells. Hypoxia induces Net depletion from target promoters, nuclear export, ubiquitylation, and proteasomal degradation. Key mediators of the hypoxic response, the prolyl-4-hydroxylases containing domain proteins (PHDs), regulate Net. PHD downregulation in normoxia leads to Net degradation, and PHD overexpression delays Net downregulation by hypoxia. Net inhibition by RNA interference or mutation leads to altered regulation by hypoxia of the Net targets PAI-1, c-fos, and egr-1. We propose that hypoxia stimulates transcription of target promoters through removal of the repressor function of Net. Interestingly, the hematocrit response to a chemical inducer of hypoxia-like responses (cobalt chloride) is strongly altered in Net mutant mice. Our results show that the Net TCF is part of the biological response to hypoxia, adding a new component to an important pathological and physiological process.

Abstract
An iron-containing, tetrapyrrole ring, heme is an essential prosthetic group in an array of proteins that comprehensively affect cellular function and metabolism; yet "free" heme in sufficient amounts can be damaging to the kidney and other organs because of its bioreactivity and pro-oxidant effects. This review discusses the cellular metabolism of heme in health and disease and covers such areas as the synthesis of heme and its utilization in heme proteins; mechanisms underlying the toxicity of heme; and the extent to which pathophysiologic processes, such as renal incorporation of heme proteins or destabilization of intracellular heme proteins, increase intracellular levels of heme and provoke renal injury. The main catabolic process that degrades heme, the heme oxygenase (HO) system, is reviewed, and evidence for the protective effects of HO-1 against acute and chronic heme/heme protein-induced renal injury is summarized. Finally, current views regarding the molecular basis for heme-induced upregulation of HO-1 are discussed.
