Abstract
Chitosan oligosaccharide (COS) is the depolymerized product of chitosan possessing various biological activities and protective effects against inflammation and oxidative injury. The aim of the present study was to investigate the antioxidant effects of COS supplements on aging-related liver dysfunction. We found that COS treatment significantly attenuated elevated liver function biomarkers and oxidative stress biomarkers and decreased antioxidative enzyme activities in liver tissues in D-galactose (D-gal)-treated mice. Furthermore, COS treatment significantly upregulated the expression of Nrf2 and its downstream target genes HO-1, NQO1, and CAT. Moreover, in vitro experiments showed that COS treatment played a vital role in protecting H2O2-exposed L02 cells against oxidative stress by activating Nrf2 antioxidant signaling. These data indicate that COS could protect against D-gal-induced hepatic aging by activating Nrf2 antioxidant signaling, which may provide novel applications for the prevention and treatment of aging-related hepatic dysfunction.

Life Sci 2020; 255:117844. [PMID: 32464124 DOI: 10.1016/j.lfs.2020.117844] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2019] [Revised: 05/19/2020] [Accepted: 05/22/2020] [Indexed: 01/03/2023]
Abstract
AIMS Interleukin (IL) 9 is a pleiotropic cytokine, and recent studies have demonstrated that IL-9 is associated with several cardiovascular diseases, via regulation of the inflammatory response. Doxorubicin (DOX) is known to induce severe cardiac injury and dysfunction by enhancing inflammation. This study aimed to investigate the role of IL-9 in DOX-induced cardiotoxicity. MATERIALS AND METHODS DOX was used to induce cardiac dysfunction and the expression of IL-9 in the murine cardiac tissues was measured. The mice were intraperitoneally injected with recombinant mouse IL-9 (rmIL-9) or anti-IL-9 neutralizing antibody (IL-9nAb) for investigating the effect of IL-9 on DOX-induced cardiac injury and dysfunction. The messenger ribonucleic acid (mRNA) expression levels of the pro-inflammatory cytokines were determined in each group by quantitative real-time polymerase chain reaction (RT-qPCR). The effect of rmIL-9 or IL-9nAb on DOX-induced apoptosis was determined both in vivo and vitro. KEY FINDINGS IL-9 levels significantly increased in the heart following DOX injection. Cardiac injury and dysfunction were induced by DOX, and treatment with IL-9nAb significantly alleviated DOX-induced injury, whereas rmIL-9 administration aggravated the cardiac damage. IL-9nAb decreased the expression of pro-inflammatory cytokines in the DOX-treated mice, while rmIL-9 administration increased the levels of pro-inflammatory cytokines. IL-9nAb reduced DOX-induced myocardial apoptosis, whereas rmIL-9 administration produced the opposite results. Additionally, IL-9nAb mitigated the DOX-induced apoptosis in H9C2 cells, while administration of rmIL-9 produced the opposite effect. SIGNIFICANCE Our results demonstrated that IL-9 aggravated DOX-induced cardiac injury and dysfunction by promoting the inflammatory response and cardiomyocyte apoptosis.

Abstract
Parkinson's disease (PD) is a neurodegenerative disorder closely associated with oxidative stress. The biochemical and cellular alterations that occur after cell and mouse treatment with the parkinsonism-inducing neurotoxin MPP+/MPTP are remarkably similar to those observed in idiopathic PD. Previously, we showed that ferulic acid (FA) has antioxidant properties and the ability to activate nuclear factor E2-related factor 2 (Nrf2). The present study tested the hypothesis that FA attenuates MPP+/MPTP-induced oxidative stress by regulating crosstalk between sirtuin 2 (SIRT2) and Nrf2 pathways. To test this hypothesis, we performed in vitro and in vivo studies using MPP+/MPTP-challenged SH-SY5Y cells or mice treated with or not with FA. FA marginally inhibited SIRT2 in parallel with α-synuclein at levels of transcription and translation in SH-SY5Y cells challenged with MPP+. Moreover, FA attenuated MPP+-induced oxidative stress, as indicated by reactive oxygen species, lipid hydroperoxides, GSH/GSSG ratio, and NAD+/NADH ratio. Mechanistically, FA strongly upregulated the glutamate cysteine ligase catalytic subunit and heme oxygenase-1 expression at the levels of transcription and translation. Interestingly, FA-mediated extracellular signal-regulated kinases 1 and 2 (ERK1/2) activation contributed to nuclear accumulation of Nrf2 via de novo synthesis, which was validated by the use of dominant negative ERK2. Surprisingly, activation of the ERK1/2 and inhibition of SIRT2 by FA are mediated by independent mechanisms. Furthermore, FA ameliorated motor deficits and oxidative stress in the ventral midbrain in MPTP-treated (25 mg/kg, i.p., daily for 5 days) wild-type mice and α-synuclein knockout mice, but not in Nrf2 knockout mice. Collectively, FA exerts antioxidant effects through ERK1/2-mediated activation of the Nrf2 pathway, and these results may have important translational value for the treatment of PD.

Dexrazoxane Protects Cardiomyocyte from Doxorubicin-Induced Apoptosis by Modulating miR-17-5p. BIOMED RESEARCH INTERNATIONAL 2020; 2020:5107193. [PMID: 32190669 PMCID: PMC7071803 DOI: 10.1155/2020/5107193] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/08/2019] [Accepted: 02/08/2020] [Indexed: 12/22/2022]
Abstract
The usage of doxorubicin is hampered by its life-threatening cardiotoxicity in clinical practice. Dexrazoxane is the only cardioprotective medicine approved by the FDA for preventing doxorubicin-induced cardiac toxicity. Nevertheless, the mechanism of dexrazoxane is incompletely understood. The aim of our study is to investigate the possible molecular mechanism of dexrazoxane against doxorubicin-induced cardiotoxicity. We established a doxorubicin-induced mouse and cardiomyocyte injury model. Male C57BL/6J mice were randomly distributed into a control group (Con), a doxorubicin treatment group (DOX), a doxorubicin plus dexrazoxane treatment group (DOX+DEX), and a dexrazoxane treatment group (DEX). Echocardiography and histology analyses were performed to evaluate heart function and structure. DNA laddering, qRT-PCR, and Western blot were performed on DOX-treated cardiomyocytes with/without DEX treatment in vitro. Cardiomyocytes were then transfected with miR-17-5p mimics or inhibitors in order to analyze its downstream target. Our results demonstrated that dexrazoxane has a potent effect on preventing cardiac injury induced by doxorubicin in vivo and in vitro by reducing cardiomyocyte apoptosis. MicroRNA plays an important role in cardiovascular diseases. Our data revealed that dexrazoxane could upregulate the expression of miR-17-5p, which plays a cytoprotective role in response to hypoxia by regulating cell apoptosis. Furthermore, the miRNA and protein analysis revealed that miR-17-5p significantly attenuated phosphatase and tensin homolog (PTEN) expression in cardiomyocytes exposed to doxorubicin. Taken together, dexrazoxane might exert a cardioprotective effect against doxorubicin-induced cardiomyocyte apoptosis by regulating the expression of miR-17-5p/PTEN cascade.

Abstract
OBJECTIVE Ginsenoside Rb1 (GRb1) is known to play an effective protection on myocardial infarction, yet its therapeutic mechanism on myocardial ischemia/reperfusion (I/R) injury has remained obscure. Here we sought to investigate the protective mechanism of GRb1 preconditioning on myocardial I/R injury in rats. METHODS AND RESULTS We report here that GRb1 preconditioning could improve myocardial I/R injury induced-cardiac functions including LVDP, -dp/dt min and + dp/dt max; however, the heart rate (HR) was maintained at a level comparable to the I/R group. Additionally, in I/R injury group given GRb1 preconditioning, release of myocardial enzymes (CK-MB and Trop l) and CtsB was decreased. Moreover, GRb1 decreased the expression of apoptotic related proteins e.g. cleaved-caspase 3; however, the ratio of Bcl-2/Bax related to anti-apoptosis was decreased. The study was extended by injecting rapamycin intraperitoneally before GRb1 pretreatment. Thus, mTOR pathway was significantly upregulated after GRb1 pretreatment when compared with I/R. Remarkably, the anti-apoptosis protection of GRb1 pretreatment was attenuated by rapamycin. Furthermore, GRb1 effectively reduced the infarct size thus supporting its role in anti-myocardial I/R injury. CONCLUSIONS It is concluded that GRb1 preconditioning can ameliorate myocardial I/R injury as manifested by the improvement of cardiac function indices; moreover, release of myocardial enzymes, namely, CK-MB, Trop l and CtsB was reduced. More importantly, we have shown that the protective effect of GRb1 against I/R injury induced cardiomyocyte apoptosis is associated with the activation of mTOR signal pathway as evident by the use of rapamycin.

Abstract
Cadmium (Cd) poisoning is characterized by multiple organ dysfunction in organisms, and the kidney is the main target organ of Cd toxicity. Trehalose (Tr), a multifunctional bioactive disaccharide, possesses potential kidney protective properties. Nevertheless, the specific biological function of Tr in antagonizing kidney injury induced by Cd remains to be elucidated. Herein, an in vivo model of Tr antagonizing Cd nephrotoxicity was established and the indictors related to kidney function, oxidative stress, and apoptosis were detected to investigate the molecular mechanism underlying the Tr-protection against Cd-induced kidney injury of rats. Firstly, Tr significantly declined the levels of blood urea nitrogen (BUN) and serum creatinine, and partially restored renal pathological changes caused by Cd. Secondly, Cd exposure significantly increased the malondialdehyde (MDA) content, and decreased the levels of total antioxidant capacity (T-AOC), superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), and glutathione (GSH) in serum. However, Tr significantly ameliorated these abnormal alterations. Moreover, Tr regulated the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway to suppress the Cd-induced nuclear translocation of Nrf2 and the up-regulation of heme oxygenase-1 (HO-1) and NAD (P) H quinone reductase-1 (NQO1). Meanwhile, Tr significantly reversed the increased Sequestosome-1(SQSTM1/p62) and decreased Kelch-like ECH associated protein-1 (Keap1) protein levels induced by Cd. Thirdly, further mechanistic exploration suggested that Tr inhibited the mitochondrial apoptotic signaling pathway induced by Cd. Collectively, the results indicated that Tr exerts antioxidant and anti-apoptosis functions involving the Nrf2 and mitochondrial apoptotic signaling pathways to protect against Cd-induced kidney injury in rats.

Abstract
Doxorubicin, as a first line chemotherapeutic agent, its usage is limited owing to cardiotoxicity. Necroptosis is a new form of programmed cell death, and recent investigations indicated that necroptosis is vitally involved in serious cardiac pathological conditions. Dexrazoxane is the only cardiac protective drug approved by FDA for anthracycline. We aimed to explore whether and how dexrazoxane regulates doxorubicin-induced cardiomyocyte necroptosis. First, doxorubicin could cause heart failure and reduce cardiomyocyte viability by promoting cell apoptosis and necroptosis in vivo and in vitro. Second, necroptosis plays an important role in doxorubicin induced cardiomyocyte injury, which could be inhibited by Nec-1. Third, dexrazoxane increased cell viability and protect heart function by decreasing both cardiomyocyte apoptosis and necroptosis after doxorubicin treatment. Forth, dexrazoxane attenuated doxorubicin-induced inflammation and necroptosis by the inhibition of p38MAPK/NF-κB pathways. These results indicated that dexrazoxane ameliorates cardiotoxicity and protects heart function by attenuating both apoptosis and necroptosis in doxorubicin induced cardiomyocyte injury.

Abstract
Buxaustroines A-N (1-14), a series of triterpenoidal alkaloids featuring a novel 17(13→18)abeo motif, were obtained from the extract of Buxus austro-yunnanensis. Their structures were assigned based on NMR data analysis and X-ray diffraction crystallography. A putative biosynthetic pathway for one of the alkaloids from a co-isolate 15 is proposed. In the assessment of their bioactivities, some of the compounds displayed protective effects against doxorubicin-induced injury of myocardial cells. Preliminary structure-activity relationship studies of 1-14, which are based on the same skeleton, were conducted.

Abstract
Acute lung injury (ALI) is a critical event involved in the pathophysiological process of acute pancreatitis (AP). Many methods have been widely used for the treatment of AP-ALI, but few are useful during early inflammation. Lipoxin A4 (LXA4), a potent available anti-inflammatory and novel antioxidant mediator, has been extensively studied in AP-ALI, but its underlying mechanism as a protective mediator is not clear. This research was conducted to identify the possible targets and mechanisms involved in the anti-AP-ALI effect of LXA4. First, we confirmed that LXA4 strongly inhibited AP-ALI in mice. Next, using ELISA, PCR, and fluorescence detection to evaluate different parameters, LXA4 was shown to reduce the inflammatory cytokine production induced by AP and block reactive oxygen species (ROS) generation in vivo and in vitro. In addition, TNF-α treatment activated the nuclear factor E2-related factor 2 (Nrf2) signaling pathway and its downstream gene heme oxygenase-1 (HO-1) in human pulmonary microvascular endothelial cells (HPMECs), and LXA4 further promoted their expression. This study also provided evidence that LXA4 phosphorylates Ser40 and triggers its nuclear translocation to activate Nrf2. Moreover, when Nrf2-knockout (Nrf2−/−) mice and cells were used to further assess the effect of the Nrf2/HO-1 pathway, we found that Nrf2 expression knockdown partially eliminated the effect of LXA4 on the reductions in inflammatory factor levels while abrogating the inhibitory effect of LXA4 on the ROS generation stimulated by AP-ALI. Overall, LXA4 attenuated the resolution of AP-induced inflammation and ROS generation to mitigate ALI, perhaps by modulating the Nrf2/HO-1 pathway. These findings have laid a foundation for the treatment of AP-ALI.

Ameliorative effect of rosiglitazone, a peroxisome proliferator gamma agonist on adriamycin-induced cardio toxicity via suppressing oxidative stress and apoptosis. IUBMB Life 2019; 72:607-615. [PMID: 31660680 DOI: 10.1002/iub.2190] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2019] [Accepted: 10/01/2019] [Indexed: 12/19/2022]
Abstract
We investigated the rosiglitazone (RSG) effect on adriamycin (ADM)-induced cardio toxicity in experimental animals. Forty adult Wistar male rats were separated into four groups as follows: normal control; RSG (10 mg/kg)-treated; ADM (10 mg/kg)-administered; and ADM (10 mg/kg) + RSG (10 mg/kg)-treated. Serum lipid level, different biochemical biomarkers, histological analysis, and nuclear factor erythroid 2-related factor/heme oxygenase-1 (Nrf2/HO-1), Caspase 3, B-cell lymphoma 2 (Bcl-2), and Bax gene expression were assessed in serum and cardiac tissue samples. Our results show that RSG treatment in ADM-administered animals significantly diminished low-density lipoprotein cholesterol, triglyceride, and total cholesterol, and increases high-density lipoprotein cholesterol (HDL-c) in comparison with the ADM group. RSG treatment reduced the effect of ADM administration on cardiac dysfunction markers such as cardiac troponin T Creatine Kinase-MB, aspartate aminotransferase, and lactate dehydrogenase, showing the amelioration of cardio toxicity in ADM-administered rats. Additionally, RSG treatment significantly decreased the level of malondialdehyde and nitric oxide in cardiovascular tissue. RSG-treated rats in combination with ADM likewise showed a significant increase in reduced glutathione, superoxide dismutase, catalase content, and the activity of glutathione peroxidase (GPx) as compared with ADM group. Moreover, RSG treatment in ADM rats significantly increased an Nrf2 and HO-1 expression in comparison with ADM group. While in apoptosis parameters, RSG treatment in ADM rats significantly diminished a cleaved caspase-3 and Bax expression as well as expanded Bcl-2 expression when contrasted with ADM group of rats. In conclusion, RSG is capable of protecting heart toxicity in ADM-treated animals through defensive effects on oxidative stress and biochemical markers.
