Abstract
The rat nematode lungworm Angiostrongylus cantonensis undergoes obligatory intracerebral migration in its hosts and causes eosinophilic meningitis or meningoencephalitis. Heme oxygenase 1 (HO-1) has several cytoprotective properties such as anti-oxidative, anti-inflammatory, and anti-apoptotic effects. HO-1 in brain tissues was induced in A. cantonensis-infected group and showed positive modulation in cobalt protoporphyrin (CoPP)-treated groups. Assay methods for the therapeutic effect include western blot analysis, enzyme-linked immunosorbent assay, gelatin zymography, blood-brain barrier permeability evaluation and eosinophil count in cerebrospinal fluid. The combination of albendazole (ABZ) and CoPP significantly decreased pro-inflammatory cytokines, tumor necrosis factor-α, interleukin (IL)-1β, IL-5, and IL-33 but significantly increased anti-inflammatory cytokines IL-10 and transforming growth factor-β. In addition, worm recovery, matrix metalloproteinase-9, BBB permeability, and eosinophil counts were decreased in the ABZ and CoPP co-treated groups. Induction of HO-1 with CoPP strongly inhibited the protein levels of caspase-3 and increased the induction of annexin-V and B-cell leukemia 2. Thus, co-treatment with ABZ and CoPP prevented A. cantonensis-induced eosinophilic meningoencephalitis and its anti-apoptotic effect by promoting HO-1 signaling prior to BBB dysfunction. HO-1 induction might be a therapeutic modality for eosinophilic meningoencephalitis.

Abstract
Oxidative stress impairs the correct course of meiotic maturation, and it is known that the oocytes are exposed to increased oxidative stress during meiotic maturation in in vitro conditions. Thus, reduction of oxidative stress can lead to improved quality of cultured oocytes. The gasotransmitter carbon monoxide (CO) has a cytoprotective effect in somatic cells. The CO is produced in cells by the enzyme heme oxygenase (HO) and the heme oxygenase/carbon monoxide (HO/CO) pathway has been shown to have an antioxidant effect in somatic cells. It has not yet been investigated whether the CO has an antioxidant effect in oocytes as well. We assessed the level of expression of HO mRNA, using reverse transcription polymerase chain reaction. The HO protein localization was evaluated by the immunocytochemical method. The influence of CO or HO inhibition on meiotic maturation was evaluated in oocytes cultured in a culture medium containing CO donor (CORM-2 or CORM-A1) or HO inhibitor Zn-protoporphyrin IX (Zn-PP IX). Detection of reactive oxygen species (ROS) was performed using the oxidant-sensing probe 2′,7′-dichlorodihydrofluorescein diacetate. We demonstrated the expression of mRNA and proteins of both HO isoforms in porcine oocytes during meiotic maturation. The inhibition of HO enzymes by Zn-PP IX did not affect meiotic maturation. CO delivered by CORM-2 or CORM-A1 donors led to a reduction in the level of ROS in the oocytes during meiotic maturation. However, exogenously delivered CO also inhibited meiotic maturation, especially at higher concentrations. In summary, the CO signaling molecule has antioxidant properties in porcine oocytes and may also be involved in the regulation of meiotic maturation.

Abstract
Previous studies have shown that tilianin alleviates ischemia-reperfusion-induced cardiomyocyte injury. However, its clinical translation has been hampered because of its insolubility in water. Tilianin-based nano-micelles that may overcome this critical issue are presented. A polyethylene glycol compound was covalently attached to propylene sulfide-formed amphiphilic diblock polymers. In the aqueous solution, tilianin is encapsulated in a hydrophobic shell to form nano-micelles. The Ph-PPS-PEG self-assembled into nanoscale micelles with a size of approximately 70 nm, termed "tilianin-loaded micelles" (TLMs). TLMs are highly efficient hydrogen peroxide scavengers and the activity of caspase-3 inhibition, thereby protecting cells from H/R-induced cytotoxicity. In addition, TLMs decreased levels of MDA, IL-1 and tumor necrosis factor (TNF-α), inhibited apoptosis, TLR4 and nuclear transcription factor (NF-κB p65) protein expression in hypoxia-reoxygenation (H/R) model. Taken together, the study suggests that TLMs may be of clinical value for the protective effects of cardiomyocytes by inhibiting Inflammation and oxidative stress during myocardial ischemia-reperfusion injury.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive malignancies and has one of the worst prognoses leading to a meager 5-year survival rate of ∼8%. Chemotherapy has had limited success in extending the life span of patients with advanced PDAC due to poor tumor perfusion and hypoxia-induced resistance. Hypoxia reprograms the gene expression profile and upregulates the expression of multiple genes including heme oxygenase-1 (HO-1), which provide survival advantage to PDAC cells. However, the relationships between HO-1, hypoxia, and response to chemotherapy is unclear. Our results showed that hypoxia upregulates the expression of HO-1 in PDAC cells, and HO-1 inhibition using the HO-1 inhibitors zinc protoporphyrin, tin protoporphyrin IX (SnPP), and HO-1 knockout using CRISPR/Cas9 suppresses the proliferation of PDAC cells under hypoxia and sensitize them to gemcitabine under in vitro conditions. Treating orthotopic tumors with SnPP, or SnPP in combination with gemcitabine, significantly reduced the weight of pancreatic tumors (P < 0.05), decreased metastasis and improved the efficacy of gemcitabine treatment (P < 0.05). Mechanistically, inhibition of HO-1 increased the production of reactive oxygen species as demonstrated by increased dihydroethidium, and Mitosox, disrupted glutathione cycle, and enhanced apoptosis. There was significant increase in cleaved caspase-3 staining in tumors after combined treatment with SnPP and gemcitabine comparing to control or gemcitabine alone. In addition, inhibiting HO-1 reduced expression of stemness markers (CD133, and CD44) as compared to control or gemcitabine. Overall, our study may present a novel therapeutic regimen that might be adopted for the treatment of PDAC patients.

Abstract
Both c-Jun N-terminal kinase (JNK) and reactive oxygen species (ROS) play important roles in myocardial ischemia/reperfusion (I/R) injury. Our previous studies suggest that N-n-butyl haloperidol iodide (F2) exerts cardioprotection by reducing ROS production and JNK activation caused by I/R. In this study, we hypothesized that there is a JNK/Sab/Src/ROS pathway in the mitochondria in H9c2 cells following hypoxia/reoxygenation (H/R) that induces oxidative stress in the mitochondria and that F2 exerts mitochondrial protective effects during H/R injury by modulating this pathway. The results showed that H/R induced higher-level ROS in the cytoplasm on the one hand and JNK activation and translocation to the mitochondria by colocalization with Sab on the other. Moreover, H/R resulted in mitochondrial Src dephosphorylation, and subsequently, oxidative stress evidenced by the increase in ROS generation and oxidized cardiolipin in the mitochondrial membranes and by the decrease in mitochondrial superoxide dismutase activity and membrane potential. Furthermore, treatment with a JNK inhibitor or Sab small interfering RNA inhibited the mitochondrial translocation of p-JNK, decreased colocalization of p-JNK and Sab on the mitochondria, and reduced Src dephosphorylation and mitochondrial oxidative stress during H/R. In addition, Src dephosphorylation by inhibitor PP2 increased mitochondrial ROS production. F2, like inhibitors of the JNK/Sab/Src/ROS pathway, downregulated the H/R-induced mitochondrial translocation of p-JNK and the colocalization of p-JNK and Sab on the mitochondria, increased Src phosphorylation, and alleviated the above-mentioned mitochondrial oxidative stress. In conclusion, F2 could ameliorate H/R-associated oxidative stress in mitochondria in H9c2 cells through the mitochondrial JNK/Sab/Src/ROS pathway.

Abstract
Autologous human cardiac stem/progenitor cell (hCPC) therapy is a promising treatment that has come into use in recent years for patients with cardiomyopathy. Though innovative in theory, a major hindrance to the practical application of this treatment is that the hCPCs of elderly patients, who are most susceptible to myocardial disease, are senescent and prone to cell death. Rejuvenating hCPCs from elderly patients may help overcome this obstacle, and can be accomplished by reversing entry into the cellular stage of senescence. p16INK4A, a cyclin dependent kinase inhibitor, is an important player in the regulation of cell senescence. In this study, we investigated whether knockdown of p16INK4A will rejuvenate aging hCPCs to a youthful phenotype. Our data indicated that upregulation of p16INK4A is associated with hCPC senescence. Both cell proliferation and survival capacity were significantly increased in hCPCs infected with lentivirus expressing p16INK4A shRNA when compared to control hCPCs. The knockdown of p16INK4A also induced antioxidant properties as indicated by a 50% decrease in ROS generation at basal cell metabolism, and a 25% decrease in ROS generation after exposure to oxidative stress. Genes associated with cell senescence (p21CIP1), anti-apoptosis (BCL2 and MCL1), anti-oxidant (CYGB, PRDX1 and SRXN1), and NFκB signal pathway (p65, IKBKB, HMOX1, etc.), were significantly upregulated after the p16INK4A knockdown. Knocking down the NFĸB-p65 expression also significantly diminished the cytoprotective effect caused by the p16INK4A knockdown. Our results suggest that genetic knockdown of p16INK4A may play a significant role in inducing antioxidant effects and extending lifespan of aging hCPCs. This genetic modification may enhance the effectiveness of autologous hCPC therapy for repair of infarcted myocardium.

Abstract
Cardiomyocyte infarction could lead to high morbidity and mortality worldwide. Recent studies demonstrated that Heme oxygenase-1 (HO-1) could exert cardiac protective effect and arouse attention. However, the detailed mechanism is still unclear. Our study provided evidences of the protective effect of HO-1 overexpression on cardiomyocytes against hypoxia/reoxygenation (H/R). We divided the treatment into four groups: the control group, H/R group, H/R+HO-1 group, and H/R+Null group. Immunofluorescent study was utilized to label the BrdU-positive and LC3-positive cells. Flow cytometry and TUNEL assay were used to examine the cell apoptosis. Protein levels of Bax, Bcl-2, Sirt3, beclin-1, LC3-I, and LC3-II were both measured using western blotting. The results indicated that HO-1 overexpression decreased the cell apoptosis and enhanced the cell proliferation. The level of Sirt3 and autophagy were also increased in H/R+HO-1 group compared with H/R group. However, ZnPP, a HO-1 inhibitor, and SiRNA of Sirt3 are both reversed the decrease of cell apoptosis of HO-1 overexpression. Moreover, ZnPP also decreased the expression of Sirt3 in HO-1 overexpression treatment group. In summary, HO-1 overexpression protects cardiomyocytes against H/R injury via ameliorating cell apoptosis and enhancing cell proliferation and autophagy through Sirt3 signaling pathway.

Abstract
AIMS Muscle damage in Duchenne muscular dystrophy (DMD) caused by the lack of dystrophin is strongly linked to inflammation. Heme oxygenase-1 (HO-1; Hmox1) is an anti-inflammatory and cytoprotective enzyme affecting myoblast differentiation by inhibiting myomiRs. The role of HO-1 has not been so far well addressed in DMD. RESULTS In dystrophin-deficient mdx mice, expression of Hmox1 in limb skeletal muscles and diaphragm is higher than in wild-type animals, being consistently elevated from 8 up to 52 weeks, both in myofibers and inflammatory leukocytes. Accordingly, HO-1 expression is induced in muscles of DMD patients. Pharmacological inhibition of HO-1 activity or genetic ablation of Hmox1 aggravates muscle damage and inflammation in mdx mice. Double knockout animals (Hmox1-/-mdx) demonstrate impaired exercise capacity in comparison with mdx mice. Interestingly, in contrast to the effect observed in muscle fibers, in dystrophin-deficient muscle satellite cells (SCs) expression of Hmox1 is decreased, while MyoD, myogenin, and miR-206 are upregulated compared with wild-type counterparts. Mdx SCs demonstrate disturbed and enhanced differentiation, which is further intensified by Hmox1 deficiency. RNA sequencing revealed downregulation of Atf3, MafK, Foxo1, and Klf2 transcription factors, known to activate Hmox1 expression, as well as attenuation of nitric oxide-mediated cGMP-dependent signaling in mdx SCs. Accordingly, treatment with NO-donor induces Hmox1 expression and inhibits differentiation. Finally, differentiation of mdx SCs was normalized by CO, a product of HO-1 activity. Innovation and Conclusions: HO-1 is induced in DMD, and HO-1 inhibition aggravates DMD pathology. Therefore, HO-1 can be considered a therapeutic target to alleviate this disease. Antioxid.

Abstract
The aim of this study was to identify the role of the precursor of the brain-derived neurotrophic factor (pro-BDNF) in myocardial hypoxia/reoxygenation injury (H/R) and to address the underlying mechanisms. For this purpose, myocardial microvascular endothelial cells (MMECs) exposed to a high concentration of glucose (30 mM) for 48 h were subjected to 4 h of hypoxia followed by 2 h of reoxygenation. Terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labeling (TUNEL) staining and flow-cytometric analysis were performed to detect apoptosis. Cell scratch and capillary-like-structure formation assays were employed to evaluate cell function. The levels of apoptosis-related proteins were evaluated by Western blotting and immunofluorescence assays. Our results showed that H/R resulted in MMEC injury, as indicated by significant increases in TUNEL-positive cell numbers and a reduction in MMEC migration and in capillary-like-structure formation coupled with increased pro-BDNF protein expression. In addition, overexpression of pro-BDNF in MMECs via a viral vector led to increased pro-BDNF expression, and this upregulation induced apoptosis. Mechanistic experiments revealed that H/R did not influence BDNF, JNK, and caspase 3 expression, but upregulated pro-BDNF, p75NTR, sortilin, phospho-JNK, and cleaved caspase 3 protein levels. In contrast, neutralization of endogenous pro-BDNF with an antibody significantly attenuated H/R-induced upregulation of pro-BDNF, p75NTR, sortilin, p-JNK, and cleaved caspase 3 protein levels, indicating that p75NTR-sortilin signaling and activation of JNK and caspase 3 may be involved in these effects. In conclusion, H/R-induced injury may be mediated by pro-BDNF, at least in part through the regulation of p75NTR-sortilin signaling and activation of JNK and caspase 3.

[PMID: 29730426 DOI: 10.1016/j.gene.2018.05.009] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2018] [Revised: 04/24/2018] [Accepted: 05/02/2018] [Indexed: 02/07/2023]
Abstract
To unveil the possible protective role of isorhamnetin, an immediate 3'-O-methylated metabolite of quercetin, in cardiomyocyte under hypoxia/reoxygenation (H/R) condition and the underlying mechanisms involved, H9c2 cardiomyocytes were exposed to the vehicle or H/R for 6 h (2 h of hypoxia following by 4 h of reoxygenation) with isorhamnetin (0, 3, 6, 12, 25, 50 μM for 4 h prior to H/R exposure). Apoptosis was evaluated by TUNEL staining, flow cytometry analysis and western blot assay for cleaved caspase-3. Myocardial injure in vivo was determined by infarct size using TTC staining, histological damage using H&E staining and myocardial apoptosis. Here, we found that isorhamnetin dose-dependently protected H9c2 cardiomyocytes against H/R-induced injure, as evidenced by the reduction in lactate dehydrogenase (LDH) levels, increases in cell viability, superoxide dismutase (SOD) and catalase (CAT) activity, with the maximal effects at 25 μΜ. In addition, isorhamnetin treatment significantly inhibited apoptosis in H/R-induced H9c2 cardiomyocytes and ameliorated H/R-induced myocardial injure in vivo, concomitant with the upregulation of sirtuin 1 (SIRT1) expression. Mechanism studies demonstrated that isorhamnetin pretreatment remarkably abolished H/R-induced downregulation of Nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) expressions and upregulation of NADPH oxidase-2/4 (NOX-2/4) expressions in cardiomyocytes. However, SIRT1 inhibition (Sirtinol) not only inhibited isorhamnetin-induced Nrf2/HO-1 upregulation and NOX-2/4 downregulation, but also alleviated its anti-apoptotic effects. Taken together, these data indicate that isorhamnetin can exhibit positive effect on H/R-induced injure by attenuating apoptosis and oxidative stress in H9c2 cardiomyocytes, which is partly attributable to the upregulation of SIRT1 and Nrf2/HO-1-mediated antioxidant signaling pathway.

Abstract
High glucose-induced cardiomyocyte death is a common symptom in advanced-stage diabetic patients, while its metabolic mechanism is still poorly understood. The aim of this study was to explore metabolic changes in high glucose-induced cardiomyocytes and the heart of streptozotocin-induced diabetic rats by 1H-NMR-based metabolomics. We found that high glucose can promote cardiomyocyte death both in vitro and in vivo studies. Metabolomic results show that several metabolites exhibited inconsistent variations in vitro and in vivo. However, we also identified a series of common metabolic changes, including increases in branched-chain amino acids (BCAAs: leucine, isoleucine and valine) as well as decreases in aspartate and creatine under high glucose condition. Moreover, a reduced energy metabolism could also be a common metabolic characteristic, as indicated by decreases in ATP in vitro as well as AMP, fumarate and succinate in vivo. Therefore, this study reveals that a decrease in energy metabolism and an increase in BCAAs metabolism could be implicated in high glucose-induced cardiomyocyte death.

Abstract
If fertilization of matured oocyte does not occur, unfertilized oocyte undergoes aging, resulting in a time-dependent reduction of the oocyte’s quality. The aging of porcine oocytes can lead to apoptosis. Carbon monoxide (CO), a signal molecule produced by the heme oxygenase (HO), possesses cytoprotective and anti-apoptotic effects that have been described in somatic cells. However, the effects of CO in oocytes have yet to be investigated. By immunocytochemistry method we detected that both isoforms of heme oxygenase (HO-1 and HO-2) are present in the porcine oocytes. Based on the morphological signs of oocyte aging, it was found that the inhibition of both HO isoforms by Zn-protoporphyrin IX (Zn-PP IX) leads to an increase in the number of apoptotic oocytes and decrease in the number of intact oocytes during aging. Contrarily, the presence of CO donors (CORM-2 or CORM-A1) significantly decrease the number of apoptotic oocytes while increasing the number of intact oocytes. We also determined that CO donors significantly decrease the caspase-3 (CAS-3) activity. Our results suggest that HO/CO contributes to the sustaining viability through regulation of apoptosis during in vitro aging of porcine oocytes.

Abstract
Myocardial hypoxia/reoxygenation (H/R) injury is one of the main causes of death and disability worldwide. However, a limited number of therapies are available to minimize the detrimental effects of this injury. Recently, researchers have demonstrated that metformin exerts direct cardioprotective effects against H/R. The aim of this study was to investigate the underlying mechanisms of how metformin affects myocardial hypoxia/reoxygenation (H/R) injury. In our study, the activities of lactate dehydrogenase (LDH) and superoxide dismutase (SOD) as well as the levels of malondialdehyde (MDA) were measured. Following H/R injury, LDH activity and MDA levels were evidently increased, while SOD activity and cell viability significantly decreased. Surprisingly, metformin downregulated the levels of relative reactive oxygen species (ROS) and upregulated the levels of relative SOD following H/R injury. Furthermore, metformin-treated cells exhibited reduced cell death, which was demonstrated to be associated with increased SIRT3 expression compared to that in the control group, as evidenced by blocking of the protective effects of metformin on cell apoptosis by the SIRT3 inhibitor Nicotinamide (NAM). Therefore, our results demonstrate that metformin improves cells viability following H/R, and this cardioprotective effect is partly mediated by the SIRT3 signaling pathway.
