Cisplatin (CDDP) is one of the most frequently used antitumor agents, but its application is significantly limited by its hepatotoxicity. In the present study, we investigated the effects of crocin against CDDP-induced oxidative stress and apoptosis in the liver of Kunming mice. Crocin was administered to the mice once daily for 7 consecutive days at the doses of 6.25 and 12.5 mg/kg body weight orally. On day 1, a single intraperitoneal injection of CDDP was given at the dose of 10 mg/kg body weight. Crocin treatment significantly improved CDDP-induced hepatic damage as indicated by serum aspartate aminotransferase and alanine aminotransferase levels. Crocin relieved CDDP-induced oxidative stress by reducing malondialdehyde level and recovering the levels of glutathione and antioxidant enzymes such as superoxide dismutase, catalase, and glutathione peroxidase. In addition, liver histopathology indicated that crocin alleviated CDDP-induced focal necrosis. Immunohistochemical staining and Western blot analysis showed that crocin significantly decreased the levels of phospho-p38 mitogen-activated protein kinase (MAPK), tumor protein 53 (p53), and cleaved caspase-3. Taken together, our data suggest that crocin provides protective effects against CDDP-induced hepatoxicity by attenuating oxidative stress and inhibiting the activation of p38 MAPK, p53, and caspase-3.

1-O-Hexyl-2,3,5-trimethylhydroquinone (HTHQ) has previously been found to have effective anti-oxidant and anti-lipid-peroxidative activity. We aimed to elucidate whether HTHQ can prevent dopaminergic neuronal cell death by investigating the effect on l-DOPA-induced cytotoxicity in PC12 cells. HTHQ protected from both l-DOPA-induced cell death and superoxide dismutase activity reduction. When assessing the effect of HTHQ on oxidative stress-related signaling pathways, HTHQ inhibited l-DOPA-induced phosphorylation of sustained extracellular signal-regulated kinases (ERK1/2), p38 mitogen-activated protein kinase (MAPK), and c-Jun N-terminal kinase (JNK1/2). HTHQ also normalized l-DOPA-reduced Bcl-2-associated death protein (Bad) phosphorylation and Bcl-2-associated X protein (Bax) expression, promoting cell survival. Taken together, HTHQ exhibits protective effects against l-DOPA-induced cell death through modulation of the ERK1/2-p38MAPK-JNK1/2-Bad-Bax signaling pathway in PC12 cells. These results suggest that HTHQ may show ameliorative effects against oxidative stress-induced dopaminergic neuronal cell death, although further studies in animal models of Parkinson’s disease are required to confirm this.

This study examined whether serotonin and two of its derivatives, [Formula: see text]-feruloylserotonin and [Formula: see text]-([Formula: see text]-coumaroyl) serotonin, have a renoprotective effect in a mouse model of cisplatin-induced acute renal failure. Cisplatin (20[Formula: see text]mg/kg body weight) was administered by intraperitoneal injection to male BALB/c mice that had received oral serotonin, [Formula: see text]-feruloylserotonin or [Formula: see text]-([Formula: see text]-coumaroyl) serotonin (7.5[Formula: see text]mg/kg body weight per day) during the preceding 2 days. At 3 days after the cisplatin injection, serum and renal biochemical factors, oxidative stress, inflammation and apoptosis-related protein expression were evaluated, and histological examinations were performed. Cisplatin caused reduction in body weight and an increase in kidney weight; however, [Formula: see text]-([Formula: see text]-coumaroyl) serotonin and [Formula: see text]-feruloylserotonin attenuated these effects. Moreover, the serotonin derivatives significantly decreased serum urea nitrogen and creatinine levels. They also significantly reduced the level of reactive oxygen species and upregulated the expression of glutathione peroxidase in the kidney. Furthermore, the serotonin derivatives improved the abnormal expression of mitogen-activated protein kinases activation-dependent inflammation- and apoptosis-related protein and caused less renal damage. These results provide important evidence that [Formula: see text]-([Formula: see text]-coumaroyl) serotonin and [Formula: see text]-feruloylserotonin exert a pleiotropic effect on several parameters related to oxidative stress, inflammation and apoptosis. The derivatives also have a renoprotective effect in cisplatin-treated mice; however, this effect is higher with [Formula: see text]-([Formula: see text]-coumaroyl) serotonin.

According to a previous study, YGDEY from tilapia fish skin gelatin hydrolysates hasstrong free radical scavenging activity. In the present study, the protective effect of YGDEY againstoxidative stress induced by ethanol in HepG2 cells was investigated. First, cells were incubatedwith YGDEY (10, 20, 50, and 100 μM) to assess cytotoxicity, and there was no significant change incell viability. Next, it was established that YGDEY decreased the production of reactive oxygenspecies (ROS). Western blot results indicated that YGDEY increased the levels of superoxidedismutase (SOD) and glutathione (GSH) and decreased the expression ofgamma-glutamyltransferase (GGT) in HepG2 cells. It was then revealed that YGDEY markedlyreduced the expressions of bax and cleaved-caspase-3 (c-caspase-3); inhibited phosphorylation ofAkt, IκB-α, p65, and p38; and increased the level of bcl-2. Moreover, the comet assay showed thatYGDEY effectively decreased the amount of ethanol-induced DNA damage. Thus, YGDEYprotected HepG2 cells from alcohol-induced injury by inhibiting oxidative stress, and this may beassociated with the Akt/nuclear factor-κB (NF-κB)/mitogen-activated protein kinase (MAPK) signaltransduction pathways. These results demonstrate that YGDEY from tilapia fish skin gelatinhydrolysates protects HepG2 cells from oxidative stress, making it a potential functional foodingredient.

Underlying Mechanisms

Oxidative stress participates in numerous myocardial pathophysiological processes and is considered a therapeutic target for myocardial ischemia and heart failure. Guanxintai (GXT), a traditional Chinese medicine, is commonly used to treat cardiovascular disease on account of its numerous beneficial physiological activities, such as dilating coronary arteries, inhibiting platelet aggregation, and reducing the serum lipid content. However, the antioxidative properties of GXT and potential underlying mechanisms remain to be established. In the present study, we investigated the protective effects of GXT on ischemic cardiomyocytes and the associated antioxidative mechanisms, both in vivo and in vitro. Notably, GXT treatment reduced the degree of cardiomyocyte injury, myocardial apoptosis, and fibrosis and partially improved cardiac function after myocardial infarction. Furthermore, GXT suppressed the level of ROS as well as expression of NADPH oxidase (NOX) and phospho-p38 mitogen-activated protein kinase (MAPK) proteins. Our results collectively suggest that the protective effects of GXT on ischemic cardiomyocytes are exerted through its antioxidative activity of NOX inhibition.

Recently, many studies have attempted to illustrate the mechanism of autophagy in protection against oxidative stress to the heart induced by H2O2. However, whether resveratrol-induced autophagy involves the p38 mitogen-activated protein kinase (MAPK) pathway is still unknown. This study aimed to investigate whether treating H9c2 cells with resveratrol increases autophagy and attenuates the cell death and apoptosis induced by oxidative stress via the p38 MAPK pathway. Resveratrol with or without SB202190, an inhibitor of the p38 MAPK pathway, was added 30 min before H2O2. After H2O2 treatment, the cells were incubated under 5% CO2 at 37 °C for 24 h to assess cell survival and death or incubated for 20 min for Western blot and transmission electron microscopy. Flow cytometry was used to detect apoptosis after 6 h of H2O2 treatment. Resveratrol at 20 µmol/L protected H9c2 cells treated with 100 µmol/L H2O2 from oxidative damage. It increased cell survival and markedly decrease lactate dehydrogenase release. In addition, resveratrol increased autophagy and decreased H2O2-induced apoptosis. Furthermore, the protective effects of resveratrol were inhibited by 10 µmol/L SB202190. Thus, resveratrol protected H2O2-treated H9c2 cells by upregulating autophagy via the p38 MAPK pathway.

The antioxidant effect of salidroside has been proven, but its role in liver injury is poorly understood. In this study, we aimed to evaluate the protective effects and mechanism of salidroside on liver injury induced by carbon tetrachloride (CCl4) in vivo. Mice were pretreated with salidroside (60 mg/kg, intraperitoneally injected, i.p.) once per day for 14 consecutive days and then administered with CCl4 (15.95 g/kg, i.p.) for 24 h to produce a liver injury model. Salidroside attenuated hepatic transaminase elevation in serum and ameliorated liver steatosis and necrosis, thereby suggesting its protective effect on the liver. Salidroside antagonized CCl4-induced toxicity by equilibrating antioxidation system, thereby inhibiting reactive oxygen species accumulation, and restoring mitochondrial structure and function. Salidroside exerts antioxidant and liver-protective effects by selectively inhibiting the activation of genes, including growth arrest and DNA -damage-inducible 45 α (Gadd45a), mitogen-activated protein kinase 7 (Mapk7), and related RAS viral oncogene homolog 2 (Rras2), which induce oxidative stress in the mitogen-activated protein kinase pathway. These results revealed that salidroside can protect the liver from CCl4-induced injury by resisting oxidative stress and protecting mitochondrial function.

Nox (NADPH oxidase)-derived ROS (reactive oxygen species) have been implicated in the development of diabetic nephropathy. Of the Nox isoforms in the kidney, Nox4 is important because of its renal abundance. In the present study, we tested the hypothesis that GKT136901, a Nox1/4 inhibitor, prevents the development of nephropathy in db/db (diabetic) mice. Six groups of male mice (8-week-old) were studied: (i) untreated control db/m, (ii) low-dose GKT136901-treated db/m (30 mg/kg of body weight per day), (iii) high-dose GKT136901-treated db/m (90 mg/kg of body weight per day), (iv) untreated db/db; (v) low dose GKT136901-treated db/db; and (vi) high-dose GKT136901-treated db/db. GKT136901, in chow, was administered for 16 weeks. db/db mice developed diabetes and nephropathy as evidenced by hyperglycaemia, albuminuria and renal injury (mesangial expansion, tubular dystrophy and glomerulosclerosis). GKT136901 treatment had no effect on plasma glucose or BP (blood pressure) in any of the groups. Plasma and urine TBARSs (thiobarbituric acid-reacting substances) levels, markers of systemic and renal oxidative stress, respectively, were increased in diabetic mice. Renal mRNA expression of Nox4, but not of Nox2, increased, Nox1 was barely detectable in db/db. Expression of the antioxidant enzyme SOD-1 (superoxide dismutase 1) decreased in db/db mice. Renal content of fibronectin, pro-collagen, TGFβ (transforming growth factor β) and VCAM-1 (vascular cell adhesion molecule 1) and phosphorylation of ERK1/2 (extracellular-signal-regulated kinase 1/2) were augmented in db/db kidneys, with no change in p38 MAPK (mitogen-activated protein kinase) and JNK (c-Jun N-terminal kinase). Treatment reduced albuminuria, TBARS and renal ERK1/2 phosphorylation and preserved renal structure in diabetic mice. Our findings suggest a renoprotective effect of the Nox1/4 inhibitor, possibly through reduced oxidative damage and decreased ERK1/2 activation. These phenomena occur independently of improved glucose control, suggesting GKT136901-sensitive targets are involved in complications of diabetes rather than in the disease process.

Cardiac Damage

Doxorubicin (DOX), an anticancer drug, causes a dose-dependent cardiotoxicity. Some evidence suggests that female children have an increased risk for DOX-mediated cardiac damage. To determine whether the iron chelator dexrazoxane (DXR) could reduce DOX-induced cardiotoxicity in the young, we injected day 10 neonate female and male rat pups with a single dose of saline or DOX, DXR, or DXR + DOX (20:1). We followed body weight gain with growth, measured cardiac hypertrophy after a 2-wk swim exercise program, markers of apoptosis (Bcl-2, BAX, BNIP1, caspase 3 activation), oxidative stress (heme oxygenase 1, protein carbonyl levels), the chaperone protein clusterin, and the transcriptional activator early growth response gene-1 (Egr-1) in hearts of nonexercised and exercised rats on neonate day 38. All DOX-alone and DXR + DOX-treated rats showed decreased weight gain, with female rats affected earlier than male rats. DXR-alone, DOX-alone, and DXR + DOX-treated rats had an increased heart weight-to-body weight (heart wt/body wt) ratio after the exercise program with female rats showing the largest increase in heart wt/body wt. Drug-treated females also showed increased cardiac apoptosis, as measured by the increased expression of the proapoptotic proteins BAX and BNIP1 and the appearance of caspase 3 activation products, and oxidative stress, as measured by increased heme oxygenase 1 expression, and reduced Egr-1 and clusterin expression when compared with the similarly treated male rats. We conclude that DXR preinjection did not reduce DOX-induced noncardiac and cardiac damage and that young female rats were more susceptible to DXR and DOX toxicities than age-matched male rats.

Neuroprotective Effects

Free radical generation and oxidative stress push forward an immense influence on the pathogenesis of neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease. Maclura tricuspidata fruit (MT) contains many biologically active substances, including compounds with antioxidant properties. The current study aimed to investigate the neuroprotective effects of MT fruit on hydrogen peroxide (H2O2)-induced neurotoxicity in SH-SY5Y cells. SH-SY5Y cells were pretreated with MT, and cell damage was induced by H2O2. First, the chemical composition and free radical scavenging properties of MT were analyzed. MT attenuated oxidative stress-induced damage in cells based on the assessment of cell viability. The H2O2-induced toxicity caused by ROS production and lactate dehydrogenase (LDH) release was ameliorated by MT pretreatment. MT also promoted an increase in the expression of genes encoding the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT). MT pretreatment was associated with an increase in the expression of neuronal genes downregulated by H2O2. Mechanistically, MT dramatically suppressed H2O2-induced Bcl-2 downregulation, Bax upregulation, apoptotic factor caspase-3 activation, Mitogen-activated protein kinase (MAPK) (JNK, ERK, and p38), and Nuclear factor-κB (NF-κB) activation, thereby preventing H2O2-induced neurotoxicity. These results indicate that MT has protective effects against H2O2-induced oxidative damage in SH-SY5Y cells and can be used to prevent and protect against neurodegeneration.
