Nuclear respiratory factor-1 negatively regulates TGF-β1 and attenuates pulmonary fibrosis. iScience 2022; 25:103535.

Abstract
The preclinical model of bleomycin-induced lung fibrosis is useful to study mechanisms related to human pulmonary fibrosis. Using BLM in mice, we find low HO-1 expression. Although a unique Rhenium-CO-releasing molecule (ReCORM) up-regulates HO-1, NRF-1, CCN5, and SMAD7, it reduces TGFβ1, TGFβr1, collagen, α-SMA, and phosphorylated Smad2/3 levels in mouse lung and in human lung fibroblasts. ChIP assay studies confirm NRF-1 binding to the promoters of TGFβ1 repressors CCN5 and Smad7. ReCORM did not blunt lung fibrosis in Hmox1-deficient alveolar type 2 cell knockout mice, suggesting this gene participates in lung protection. In human lung fibroblasts, TGFβ1-dependent production of α-SMA is abolished by ReCORM or by NRF-1 gene transfection. We demonstrate effective HO-1/NRF-1 signaling in lung AT2 cells protects against BLM induced lung injury and fibrosis by maintaining mitochondrial health, function, and suppressing the TGFβ1 pathway. Thus, protection of AT2 cell mitochondrial integrity via HO-1/NRF-1 presents an innovative therapeutic target.

Abstract
Hypoxia-inducible factor prolyl hydroxylase domain 2 (PHD2) is an important oxygen sensor in animals. By using the CO-releasing molecule-2 (CORM-2) as an in situ CO donor, we demonstrate that CO is an inhibitor of PHD2. This report provides further evidence about the emerging role of CO in oxygen sensing and homeostasis.

Abstract
Supplemental Digital Content is available in the text. Objectives: Carbon monoxide (CO) produced by haem oxygenases or released by CO-releasing molecules (CORM) affords antiplatelet effects, but the mechanism involved has not been defined. Here, we tested the hypothesis that CO–induced inhibition of human platelet aggregation is mediated by modulation of platelet bioenergetics. Approach and Results: To analyze the effects of CORM-A1 on human platelet aggregation and bioenergetics, a light transmission aggregometry, Seahorse XFe technique and liquid chromatography tandem-mass spectrometry–based metabolomics were used. CORM-A1–induced inhibition of platelet aggregation was accompanied by the inhibition of mitochondrial respiration and glycolysis. Interestingly, specific inhibitors of these processes applied individually, in contrast to combined treatment, did not inhibit platelet aggregation considerably. A CORM-A1–induced delay of tricarboxylic acid cycle was associated with oxidized nicotinamide adenine dinucleotide (NAD+) depletion, compatible with the inhibition of oxidative phosphorylation. CORM-A1 provoked an increase in concentrations of proximal (before GAPDH [glyceraldehyde 3-phosphate dehydrogenase]), but not distal glycolysis metabolites, suggesting that CO delayed glycolysis at the level of NAD+–dependent GAPDH; however, GAPDH activity was directly not inhibited. In the presence of exogenous pyruvate, CORM-A1–induced inhibition of platelet aggregation and glycolysis were lost, but were restored by the inhibition of lactate dehydrogenase, involved in cytosolic NAD+ regeneration, pointing out to the key role of NAD+ depletion in the inhibition of platelet bioenergetics by CORM-A1. Conclusions: The antiplatelet effect of CO is mediated by inhibition of mitochondrial respiration—attributed to the inhibition of cytochrome c oxidase, and inhibition of glycolysis—ascribed to cytosolic NAD+ depletion.

Effects of frequently applied carbon monoxide releasing molecules (CORMs) in typical CO-sensitive model systems - A comparative in vitro study. Arch Biochem Biophys 2020; 687:108383. [PMID: 32335048 DOI: 10.1016/j.abb.2020.108383] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 04/15/2020] [Accepted: 04/16/2020] [Indexed: 12/18/2022]
Abstract
Intracellular carbon monoxide (CO) is a gaseous signaling molecule and is generated enzymatically by heme oxygenases upon degradation of heme to billiverdin. Target structures for intracellular produced CO are heme proteins including cytochrome c oxidase of the respiratory chain, cytochrome P450-dependent monooxygenases, or myoglobin. For studies on CO signaling, CO-releasing molecules (CORMs) of different structure are available. Here, three frequently used CORMs (CORM-2, CORM-3 and CORM-401) were studied for their properties to provide CO in biological test systems and address susceptible heme proteins. CO release was investigated in the myoglobin binding assay and found to be rapid (<5 min) with CORM-2- and CORM-3, whereas CORM-401 continuously provided CO (>50 min). Storage stability of CORM stock solutions was also assessed with the myoglobin assay. Only CORM-401 stock solutions were stable over a period of 7 days. Incubation of CORMs with recombinant cytochrome P450 led to an inhibition of enzyme activity. However, only CORM-3 and CORM-401 proved to be suitable in this test system because controls with the inactivated CORM-2 (iCORM-2) also led to a loss of enzyme activity. The impact of CORMs on the respiratory chain was investigated with high resolution respirometry and extracellular flux technology. In the first approach interferences of CORM-2 and CORM-3 with oxygen measurement occurred, since a rapid depletion of oxygen was detected in the medium even when no cells were present. However, CORM-401 did not interfere with oxygen measurement and the expected inhibition of cellular respiration was observed. CORM-2 was not suitable for use in oxygen measurements with the extracellular flux technology and CORM-3 application did not show any effect in this system. However, CO-dependent inhibition of cellular respiration was observed with CORM-401. Based on the present experiments it is concluded, that CORM-401 produced most reliable CO-specific results for the modulation of typical CO targets. For studies on CO-dependent biological effects on intracellular heme groups, CORM-2 and CORM-3 were less suitable. Depending on the experimental setting, data achieved with these compounds should be evaluated with caution.

Abstract
Carbon monoxide (CO) is a gasotransmitter produced in humans. An essential unanswered question in the design of carbon monoxide releasing molecules (CORMs) is whether the delivery molecule should be localized extra- or intracellularly to produce desired biological effects. Herein we show that extracellular CO release is less toxic and is sufficient to produce an anti-inflammatory effect similar to that of intracellular CO release at nanomolar concentrations. This information is valuable for the design of CORMs.

Abstract
Carbon monoxide (CO) at low, non-toxic concentrations has been previously demonstrated to exert anti-inflammatory protection in murine models of sickle cell disease (SCD). However CO delivery by inhalation, CO-hemoglobin infusion or CO-releasing molecules presents problems for daily CO administration. Oral administration of a CO-saturated liquid avoids many of these issues and potentially provides a platform for self-administration to SCD patients. To test if orally-delivered CO could modulate SCD vaso-occlusion and inflammation, a liquid CO formulation (HBI-002) was administered by gavage (10 ml/kg) once-daily to NY1DD and Townes-SS transgenic mouse models of SCD. Baseline CO-hemoglobin (CO-Hb) levels were 1.6% and 1.8% in NY1DD and Townes-SS sickle mice and 0.6% in Townes-AS control mice. CO-Hb levels reached 5.4%, 4.7% and 3.0% within 5 minutes in NY1DD, SS and AS mice respectively after gavage with HBI-002. After ten treatments, each once-daily, hemoglobin levels rose from 5.3g/dL in vehicle-treated Townes-SS mice to 6.3g/dL in HBI-002-treated. Similarly, red blood cell (RBC) counts rose from 2.36 x 106/μL in vehicle-treated SS mice to 2.89 x 106/μL in HBI-002-treated mice. In concordance with these findings, hematocrits rose from 26.3% in vehicle-treated mice to 30.0% in HBI-002-treated mice. Reticulocyte counts were not significantly different between vehicle and HBI-002-treated SS mice implying less hemolysis and not an increase in RBC production. White blood cell counts decreased from 29.1 x 103/μL in vehicle-treated versus 20.3 x 103/μL in HBI-002-treated SS mice. Townes-SS mice treated with HBI-002 had markedly increased Nrf2 and HO-1 expression and decreased NF-κB activation compared to vehicle-treated mice. These anti-inflammatory effects were examined for the ability of HBI-002 (administered orally once-daily for up to 5 days) to inhibit vaso-occlusion induced by hypoxia-reoxygenation. In NY1DD and Townes-SS sickle mice, HBI-002 decreased microvascular stasis in a duration-dependent manner. Collectively, these findings support HBI-002 as a useful anti-inflammatory agent to treat SCD and warrants further development as a therapeutic.

Abstract
While interactions between carbon monoxide (CO) and mitochondria have been previously studied, the methods used to deliver CO (gas or CO-releasing metal carbonyl compounds) lack subcellular targeting and/or controlled delivery. Thus, the effective concentration needed to produce changes in mitochondrial bioenergetics is yet to be fully defined. To evaluate the influence of mitochondrial-targeted versus intracellularly released CO on mitochondrial oxygen consumption rates, we developed and characterized flavonol-based CO donor compounds that differ at their site of release. These molecules are metal-free, visible light triggered CO donors (photoCORMs) that quantitatively release CO and are trackable in cells via confocal microscopy. Our studies indicate that at a concentration of 10 μM, the mitochondrial-localized and cytosolic CO-releasing compounds are similarly effective in terms of decreasing ATP production, maximal respiration, and the reserve capacity of A549 cells. This concentration is the lowest to impart changes in mitochondrial bioenergetics for any CO-releasing molecule (CORM) reported to date. The results reported herein demonstrate the feasibility of using a structurally tunable organic photoCORM framework for comparative intracellular studies of the biological effects of carbon monoxide.

Abstract
Carbon monoxide (CO) modulates mitochondrial respiration, but the mechanisms involved are not completely understood. The aim of the present study was to investigate the acute effects of CO on bioenergetics and metabolism in intact EA.hy926 endothelial cells using live cell imaging techniques. Our findings indicate that CORM-401, a compound that liberates CO, reduces ATP production from glycolysis, and induces a mild mitochondrial depolarization. In addition, CO from CORM-401 increases mitochondrial calcium and activates complexes I and II. The subsequent increase in mitochondrial respiration leads to ATP production through oxidative phosphorylation. Thus, our results show that nonactivated endothelial cells rely primarily on glycolysis, but in the presence of CO, mitochondrial Ca2+ increases and activates respiration that shifts the metabolism of endothelial cells from glycolysis- to oxidative phosphorylation-dependent ATP production.

Recent evidence indicates that mitochondria are among a number of molecular targets that mediate the cellular actions of CO. In the present study we characterized the effects of CO released from CORM-401 on mitochondrial respiration and glycolysis in intact human endothelial cells using electron paramagnetic resonance (EPR) oximetry and the Seahorse XF technology. We found that CORM-401 (10-100μM) induced a persistent increase in the oxygen consumption rate (OCR) that was accompanied by inhibition of glycolysis (extracellular acidification rate, ECAR) and a decrease in ATP-turnover. Furthermore, CORM-401 increased proton leak, diminished mitochondrial reserve capacity and enhanced non-mitochondrial respiration. Inactive CORM-401 (iCORM-401) neither induced mitochondrial uncoupling nor inhibited glycolysis, supporting a direct role of CO in the endothelial metabolic response induced by CORM-401. Interestingly, blockade of mitochondrial large-conductance calcium-regulated potassium ion channels (mitoBKCa) with paxilline abolished the increase in OCR promoted by CORM-401 without affecting ECAR; patch-clamp experiments confirmed that CO derived from CORM-401 activated mitoBKCa channels present in mitochondria. Conversely, stabilization of glycolysis by MG132 prevented CORM-401-mediated decrease in ECAR but did not modify the OCR response. In summary, we demonstrated in intact endothelial cells that CO induces a two-component metabolic response: uncoupling of mitochondrial respiration dependent on the activation of mitoBKCa channels and inhibition of glycolysis independent of mitoBKCa channels.

Abstract
Background Carbon monoxide (CO), a byproduct of heme degradation, is attracting growing attention from the scientific community. At physiological concentrations, CO plays a role as a signal messenger that regulates a number of physiological processes. CO releasing molecules are under evaluation in preclinical models for the management of inflammation, sepsis, ischemia/reperfusion injury, and organ transplantation. Because of our discovery that nitric oxide signaling actively down-regulates integrin affinity and cell adhesion, and the similarity between nitric oxide and CO-dependent signaling, we studied the effects of CO on integrin signaling and cell adhesion. Results We used a cell permeable CO releasing molecule (CORM-2) to elevate intracellular CO, and a fluorescent Very Late Antigen-4 (VLA-4, α4β1-integrin)-specific ligand to evaluate the integrin state in real-time on live cells. We show that the binding of the ligand can be rapidly down-modulated in resting cells and after inside-out activation through several Gαi-coupled receptors. Moreover, cell treatment with hemin, a natural source of CO, resulted in comparable VLA-4 ligand dissociation. Inhibition of VLA-4 ligand binding by CO had a dramatic effect on cell-cell interaction in a VLA-4/VCAM-1-dependent cell adhesion system. Conclusions We conclude that the CO signaling pathway can rapidly down-modulate binding of the VLA-4 -specific ligand. We propose that CO-regulated integrin deactivation provides a basis for modulation of immune cell adhesion as well as rapid cell mobilization, for example as shown for splenic monocytes in response to surgically induced ischemia of the myocardium.

Lower obesity rate during residence at high altitude among a military population with frequent migration: a quasi experimental model for investigating spatial causation. PLoS One 2014; 9:e93493.

Abstract
We sought to evaluate whether residence at high altitude is associated with the development of obesity among those at increased risk of becoming obese. Obesity, a leading global health priority, is often refractory to care. A potentially novel intervention is hypoxia, which has demonstrated positive long-term metabolic effects in rats. Whether or not high altitude residence confers benefit in humans, however, remains unknown. Using a quasi-experimental, retrospective study design, we observed all outpatient medical encounters for overweight active component enlisted service members in the U.S. Army or Air Force from January 2006 to December 2012 who were stationed in the United States. We compared high altitude (>1.96 kilometers above sea level) duty assignment with low altitude (<0.98 kilometers). The outcome of interest was obesity related ICD-9 codes (278.00-01, V85.3x-V85.54) by Cox regression. We found service members had a lower hazard ratio (HR) of incident obesity diagnosis if stationed at high altitude as compared to low altitude (HR 0.59, 95% confidence interval [CI] 0.54–0.65; p<0.001). Using geographic distribution of obesity prevalence among civilians throughout the U.S. as a covariate (as measured by the Centers for Disease Control and Prevention and the REGARDS study) also predicted obesity onset among service members. In conclusion, high altitude residence predicts lower rates of new obesity diagnoses among overweight service members in the U.S. Army and Air Force. Future studies should assign exposure using randomization, clarify the mechanism(s) of this relationship, and assess the net balance of harms and benefits of high altitude on obesity prevention.

Abstract
BACKGROUND/AIMS Carbon monoxide (CO) interferes with cytochrome-dependent cellular functions and acts as gaseous transmitter. CO is released from CO-releasing molecules (CORM) including tricarbonyl-dichlororuthenium (II) dimer (CORM-2), molecules considered for the treatment of several disorders including vascular dysfunction, inflammation, tissue ischemia and organ rejection. Cytochrome P450-sensitive function include formation of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) by renal 25-hydroxyvitamin D3 1-alpha-hydroxylase (Cyp27b1). The enzyme is regulated by PTH, FGF23 and klotho. 1,25(OH)2D3 regulates Ca(2+) and phosphate transport as well as klotho expression. The present study explored, whether CORM-2 influences 1,25(OH)2D3 formation and klotho expression. METHODS Mice were treated with intravenous CORM-2 (20 mg/kg body weight). Plasma 1,25(OH)2D3 and FGF23 concentrations were determined by ELISA, phosphate, calcium and creatinine concentrations by colorimetric methods, transcript levels by quantitative RT-PCR and protein expression by western blotting. Fgf23 mRNA transcript levels were further determined in rat osteosarcoma UMR106 cells without or with prior treatment for 24 hours with 20 µM CORM-2. RESULTS CORM-2 injection within 24 hours significantly increased FGF23 plasma levels and decreased 1,25(OH)2D3 plasma levels, renal Cyp27b1 gene expression as well as renal klotho protein abundance and transcript levels. Moreover, treatment of UMR106 cells with CORM-2 significantly increased Fgf23 transcript levels. CONCLUSION CO-releasing molecule CORM-2 enhances FGF23 expression and release and decreases klotho expression and 1,25(OH)2D3 synthesis. © 2013 S. Karger AG, Basel.
