Hydrogen Peroxide 68-72 heme oxygenase 1 Homo sapiens 48-64 17559630-1 2007 BACKGROUND AND OBJECTIVE: Although induction of heme oxygenase-1 by H2O2 has been reported, the protective role of heme oxygenase-1 against the cytotoxic and osteoclastogenic effects of H2O2 have not been elucidated in human periodontal ligament cells. Hydrogen Peroxide 186-190 heme oxygenase 1 Homo sapiens 115-131 17559630-2 2007 The aim of this work was to investigate the defense mechanism of heme oxygenase-1 on H2O2-induced cytotoxicity and to analyze the expression of receptor activator of nuclear factor-kappaB ligand (RANKL) and osteoprotegerin as markers for osteoclast differentiation in periodontal ligament cells. Hydrogen Peroxide 85-89 heme oxygenase 1 Homo sapiens 65-81 17559630-4 2007 RESULTS: H2O2 produced a cytotoxic effect by reducing the cell viability and enhancing the expression of heme oxygenase-1 and RANKL mRNAs in a concentration- and time-dependent manner. Hydrogen Peroxide 9-13 heme oxygenase 1 Homo sapiens 105-121 16378625-10 2006 On the other hand, pretreatment of these cells with EGCG exerts significant cytoprotective effects against H2O2, suggesting that the induction of HO-1 is an important component in the protection against oxidative stress. Hydrogen Peroxide 107-111 heme oxygenase 1 Homo sapiens 146-150 17339489-8 2007 The same low H(2)O(2) concentration also induced the anti-inflammatory gene coding for heme oxygenase-1 (HO-1) and IL-6. Hydrogen Peroxide 13-21 heme oxygenase 1 Homo sapiens 87-103 17339489-8 2007 The same low H(2)O(2) concentration also induced the anti-inflammatory gene coding for heme oxygenase-1 (HO-1) and IL-6.

Hydrogen Peroxide 181-198 heme oxygenase 1 Homo sapiens 92-96 17559630-6 2007 CONCLUSION: These data suggest that heme oxygenase-1 induction plays a protective role in periodontal ligament cells against the cytotoxic and RANKL-inducing effects of H2O2, through multiple signaling pathways. Hydrogen Peroxide 169-173 heme oxygenase 1 Homo sapiens 36-52 16298686-4 2005 In neuron-glia cultures, we found that H2O2, a product of dopamine metabolism, or l-3,4-dihydroxyphenylalanine (L-DOPA), the dopamine precursor used in the therapy of PD, induced a fast up-regulation of HO-1 mRNA and protein levels, followed by a secondary down-regulation. Hydrogen Peroxide 39-43 heme oxygenase 1 Homo sapiens 203-207 16337498-7 2006 Coincubation of C (0.5-1.0-2.0 mM), AC (0.1-0.2-0.4 mM) and PC (0.05-0.1-0.2 mM) with H2O2 further increased HO-1 gene expression and not only normalized vs. H2O2 but even increased vs. basal ecNOS mRNA. Hydrogen Peroxide 86-90 heme oxygenase 1 Homo sapiens 109-113 16298686-5 2005 H2O2 and L-DOPA also increased HO-1 expression in astrocyte cultures, but with a delayed time course in H2O2-treated cultures. Hydrogen Peroxide 0-4 heme oxygenase 1 Homo sapiens 31-35 16298686-7 2005 Because exogenously applied GDNF prevented HO-1 up-regulation in cultures treated with H2O2 or l-DOPA, and antibody neutralization of GDNF prevented the secondary HO-1 down-regulation observed in neuron-glia cultures, we propose that GDNF negatively modulates HO-1 expression induced by oxidative stress. Hydrogen Peroxide 87-91 heme oxygenase 1 Homo sapiens 43-47 10631150-8 2000 H2O2 exposure up-regulated the transcriptional activity of the HO-1 promoter/luciferase fusion genes with (GT)16 or (GT)20 but did not do so with (GT)29 or (GT)38. Hydrogen Peroxide 0-4 heme oxygenase 1 Homo sapiens 63-67 15589375-0 2005 Distinct protective mechanisms of HO-1 and HO-2 against hydroperoxide-induced cytotoxicity.

Hydrogen Peroxide 56-73 heme oxygenase 1 Homo sapiens 10-14 15207648-7 2004 We found that HO-1 induction in astrocytes is increased by combined exposure to Pb2+ and many other stresses, including heat, nitric oxide, H2O2, and superoxide. Hydrogen Peroxide 140-144 heme oxygenase 1 Homo sapiens 14-18 12118938-4 2002 However, the resistance of the HO-1 transfected VSMC against H2O2 was significantly raised. Hydrogen Peroxide 61-65 heme oxygenase 1 Homo sapiens 31-35 11581219-6 2001 Differentiated ARPE-19 cells treated with tBH or H2O2 resulted in upregulation of the HO-1 and FGFR1 transcripts. Hydrogen Peroxide 49-53 heme oxygenase 1 Homo sapiens 86-90 15213272-5 2004 The presence of catalase significantly prevented the upregulation of HO-1 in SSAT overexpressing cells, indicating that generation of H2O2 is partially responsible for the induction of oxidative stress. Hydrogen Peroxide 134-138 heme oxygenase 1 Homo sapiens 69-73 11930234-5 2002 It was found that the HO-1 transfected-VSMCs presented dominant resistance to toxicity produced by exposure to H2O2, as a significant protective effect of HO-1 marked by cell survival and LDH leakage was observed when 200, 400 and 600 micromol/L of H2O2 were used. Hydrogen Peroxide 111-115 heme oxygenase 1 Homo sapiens 22-26 11930234-5 2002 It was found that the HO-1 transfected-VSMCs presented dominant resistance to toxicity produced by exposure to H2O2, as a significant protective effect of HO-1 marked by cell survival and LDH leakage was observed when 200, 400 and 600 micromol/L of H2O2 were used. Hydrogen Peroxide 111-115 heme oxygenase 1 Homo sapiens 155-159 11930234-5 2002 It was found that the HO-1 transfected-VSMCs presented dominant resistance to toxicity produced by exposure to H2O2, as a significant protective effect of HO-1 marked by cell survival and LDH leakage was observed when 200, 400 and 600 micromol/L of H2O2 were used. Hydrogen Peroxide 249-253 heme oxygenase 1 Homo sapiens 22-26 11171043-9 2001 H(2)O(2) also activated the CdRE-binding activity, and pretreatment with N-acetyl-L-cysteine, which replenishes the intracellular levels of GSH, suppressed, in TS-treated cells, both the CdRE-binding activity and the increased HO-1 expression. Hydrogen Peroxide 0-8 heme oxygenase 1 Homo sapiens 227-231 10644516-6 2000 In contrast, HO-1 induction by the oxidants, H(2)O(2) and carbonyl cyanide m-chlorophenylhydrazone (CCCP) was significantly attenuated in the presence of free radical scavengers. Hydrogen Peroxide 45-53 heme oxygenase 1 Homo sapiens 13-17 10425949-2 1999 Synthesis of the enzyme heme oxygenase-1 (HO-1) is increased after exposure of eukaryotic cells to conditions of oxidative stress (including H2O2) as a defense against the damaging effects of free radicals. Hydrogen Peroxide 141-145 heme oxygenase 1 Homo sapiens 24-40 10460761-9 1999 These findings suggest that HO-1 induction provides protection against H(2)O(2)-induced injury of the cultured human airway epithelial cells in part via the HO-bilirubin pathway. Hydrogen Peroxide 71-79 heme oxygenase 1 Homo sapiens 28-32 10409239-7 1999 The protective effect of enhancement of HO-1 activity against heme and H(2)O(2) was reversed by pretreatment with stannic mesoporphyrin, a competitive inhibitor of HO. Hydrogen Peroxide 71-79 heme oxygenase 1 Homo sapiens 40-44 10513606-10 1999 Strain treatment, similar to H2O2 exposure, induced HO-1 expression in a time-dependent manner. Hydrogen Peroxide 29-33 heme oxygenase 1 Homo sapiens 52-56 10425949-2 1999 Synthesis of the enzyme heme oxygenase-1 (HO-1) is increased after exposure of eukaryotic cells to conditions of oxidative stress (including H2O2) as a defense against the damaging effects of free radicals. Hydrogen Peroxide 141-145 heme oxygenase 1 Homo sapiens 42-46 10218639-1 1999 Induction of heme oxygenase 1 transcription and enzymatic activity is a common response after exposure of cells to various forms of oxidative stress including ultraviolet A radiation (UVA) and hydrogen peroxide. Hydrogen Peroxide 193-210 heme oxygenase 1 Homo sapiens 13-29 10218639-4 1999 We also demonstrate a high degree of correlation between the amount of heme released and the degree of subsequent induction of heme oxygenase 1 transcription following UVA and hydrogen peroxide treatment. Hydrogen Peroxide 176-193 heme oxygenase 1 Homo sapiens 127-143 8783636-2 1996 BSC-1 cells adapted by long-term exposure to H2O2 exhibited a twofold increase in basal HO activity and expression of HO-1 mRNA as compared with their wild-type counterparts. Hydrogen Peroxide 45-49 heme oxygenase 1 Homo sapiens 118-122 9747510-7 1998 In addition to hyperoxia, sodium arsenite (NaAsO2), cadmium chloride (CdCl(2)) and hydrogen peroxide (H2O2), which are reactive oxygen intermediates (ROI) generators, increased the HO-1 mRNA level by 11-, 22- and 2.5-fold, respectively. Hydrogen Peroxide 83-100 heme oxygenase 1 Homo sapiens 181-185 9747510-7 1998 In addition to hyperoxia, sodium arsenite (NaAsO2), cadmium chloride (CdCl(2)) and hydrogen peroxide (H2O2), which are reactive oxygen intermediates (ROI) generators, increased the HO-1 mRNA level by 11-, 22- and 2.5-fold, respectively. Hydrogen Peroxide 102-106 heme oxygenase 1 Homo sapiens 181-185 9054378-1 1997 Conversion of heme to verdoheme by heme oxygenase-1 (HO-1) is thought to involve alpha-meso-hydroxylation and elimination of the meso-carbon as CO, a reaction supported by both H2O2 and NADPH-cytochrome P450 reductase/O2. Hydrogen Peroxide 177-181 heme oxygenase 1 Homo sapiens 35-51 8783636-3 1996 Exposure of both adapted and wild-type BSC-1 cells to H2O2 induced HO-1 mRNA. Hydrogen Peroxide 54-58 heme oxygenase 1 Homo sapiens 67-71 8783636-8 1996 In conclusion, two interrelated stressors, H2O2 and hemin, produced a stimulation of HO-1, and this was associated with a reduction in the viability of BSC-1 cells. Hydrogen Peroxide 43-47 heme oxygenase 1 Homo sapiens 85-89 8600294-9 1995 In addition, exposure to hydrogen peroxide (H2O2), cadmium (Cd), and lipopolysaccharide (LPS) stimulated a rise in HO-1 levels. Hydrogen Peroxide 25-42 heme oxygenase 1 Homo sapiens 115-119 8600294-9 1995 In addition, exposure to hydrogen peroxide (H2O2), cadmium (Cd), and lipopolysaccharide (LPS) stimulated a rise in HO-1 levels. Hydrogen Peroxide 44-48 heme oxygenase 1 Homo sapiens 115-119 33775716-0 2021 The signaling pathway PI3K/Akt/Nrf2/HO-1 plays a role in the mitochondrial protection promoted by astaxanthin in the SH-SY5Y cells exposed to hydrogen peroxide. Hydrogen Peroxide 142-159 heme oxygenase 1 Homo sapiens 36-40 33775716-9 2021 Inhibition of the PI3K/Akt or of the HO-1 enzyme abolished the AST-induced mitochondrial protection in cells challenged with H2O2. Hydrogen Peroxide 125-129 heme oxygenase 1 Homo sapiens 37-41 33775716-11 2021 Thus, we suggest that AST promotes mitochondrial protection by a mechanism dependent on the PI3K/Akt/Nrf2/HO-1 signaling pathway in SH-SY5Y cells exposed to H2O2. Hydrogen Peroxide 157-161 heme oxygenase 1 Homo sapiens 106-110 34874275-8 2021 As an HO-1 inducer, cobalt protoporphyrin IX (CoPP) decreased ROS production and significantly reversed the inhibitory effect of H2O2 on cell viability.

Hydrogen Peroxide 10-14 heme oxygenase 1 Homo sapiens 75-79 34476501-4 2021 The expression levels of apoptosis-related proteins, activation of the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway induced by H2O2 and the effect of treatment with ANP on vertebral EPCs were detected by western blotting. Hydrogen Peroxide 175-179 heme oxygenase 1 Homo sapiens 122-138 34476501-4 2021 The expression levels of apoptosis-related proteins, activation of the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway induced by H2O2 and the effect of treatment with ANP on vertebral EPCs were detected by western blotting. Hydrogen Peroxide 175-179 heme oxygenase 1 Homo sapiens 140-144 34476501-8 2021 Finally, ANP blocked H2O2-induced oxidative stress through activating the Nrf2/HO-1 signaling pathway. Hydrogen Peroxide 21-25 heme oxygenase 1 Homo sapiens 79-83 34476501-9 2021 These findings suggested that ANP may effectively protect EPCs through inhibition of H2O2-induced oxidant injury and cell death by activating the Nrf2/HO-1 signaling pathway. Hydrogen Peroxide 85-89 heme oxygenase 1 Homo sapiens 151-155 34876806-13 2021 Conclusion: Our results indicate that MeCbl attenuated the H2O2-induced oxidative stress in melanocytes by activating the Nrf2/HO-1 pathway, this suggests that MeCbl may be an effective treatment against vitiligo.

Hydrogen Peroxide 38-43 heme oxygenase 1 Homo sapiens 136-140 34305600-6 2021 At the same time, the GN combination could also inhibit the H2O2-induced inflammatory response and apoptosis of human umbilical vein endothelial cells (HUVECs), which is mainly related to the activation of the AMPK/mTOR pathway by GN combination, which in turn induces the activation of Nrf2/HO-1 signal. Hydrogen Peroxide 60-64 heme oxygenase 1 Homo sapiens 292-296 34104310-8 2021 In particular, the methanol extract was the most effective in protecting neuron-like SH-SY5Y cells against H2O2-induced oxidative stress by upregulating endogenous antioxidant enzymes such as thioredoxin reductase, heme oxygenase 1, NADPH quinone oxidoreductase, and glutathione reductase. Hydrogen Peroxide 107-111 heme oxygenase 1 Homo sapiens 215-231 35306372-3 2022 Photochemical oxidation of isoprene leads to the formation of hydroperoxides, environmental oxidants that lead to inflammatory (IL-8) and adaptive (HMOX1) gene expression in human airway epithelial cells (HAEC).
