Abstract
BACKGROUND Testicular torsion is a urological emergency that requires urgent surgical intervention which results in testicular loss if not diagnosed and treated in a timely fashion. Ischemic tissue damage with oxygen deficiency, which starts with the decrease in blood flow to the tissue, continues to increase with the reoxygenation of the damaged tissues as soon as reperfusion is achieved. In various studies, osthole has also been shown to reduce cerebral, spinal cord, intestinal, renal, and myocardial ischemia/perfusion (I/R) damage. The aim of this study is to examine the effects of osthole on testicular I/R injury. METHODS 28 Wistar-albino rats were randomly divided into four experimental groups (n=7). Group 1 was the sham operation group. In Group 2 (I/R), 3-h ischemia was created by rotating the testis 720° clockwise, followed by 3 h of reperfusion. In Group 3 (I/R + single dose of Osthole), 20 mg/kg ostol was administered intraperitoneally half an hour before detorsion after 3 h of torsion. The testis was detorsioned. Three h of detorsion was applied. In Group 4 (I/R + twice doses of Osthole), 20 mg/kg ostol was administered intraperitoneally half an hour before detorsion, followed by 3-h torsion. The testis was released and detorsioned. Half an hour after the detorsion, an intraperitoneal dose of 20 mg/kg osthole was administered again. Detorsion was done for 3 h. All rats were sacrificed after 6 h and right orchiectomy was performed for blood for biochemical analysis and histopathological sample. RESULTS Glutathion, nuclear respiratory factor 2, Superoxide dismutase, and 8-hydroxydeoxyguanosine levels were decreased in I/R rats, while interleukin-6, malondialdehyde, and myeloperoxidase levels were increased. While caspase 3, caspase 8, caspase 9, and TUNEL showed moderate immunopositive tissues immunohistochemically in rats with I/R damage, mild immunopositive tissues were detected in Group 3 and Group 4. In the histochemical examination, degenerative tubule structure and separation of epithelial cells were observed in I/R rats, while partially healed testicular tissue was detected in Group 3 and Group 4. CONCLUSION In our study, we observed that osthole reduced oxidative damage, suppressed the inflammatory process, prevented apoptosis, and reduced cell damage. We think that with repeated doses, cellular damage would gradually decline.

Abstract
Avian tibial dyschondroplasia affects fast growing broiler chickens accounting for almost 30% of leg ailments in broilers. The present project was designed to assess the efficacy of osthole against avian tibial dyschondroplasia (TD). Two hundred and forty chickens were equally allocated into control, TD and osthole groups (n = 80). The TD and osthole group chickens were challenged with tetramethylthiuram disulfide (thiram) at 50 mg/kg of feed from 4–7 days, followed by osthole administration at 20 mg/kg orally to the osthole group only from 8–18 days. Thiram feeding resulted in lameness, increased mortality, and decreased production parameters, alkaline phosphatase (ALP), superoxide dismutase (SOD), total antioxidant capacity (T-AOC), and glutathione peroxidase (GSH-PX) levels, along with significantly increased aspartate aminotransferase (AST), alanine aminotransferase (ALT), malondialdehyde (MDA) levels, and growth plate size. Moreover, the genes and protein expressions of BMP-2 and RUNX-2 were significantly down-regulated in TD affected chickens (p < 0.05). Osthole administration showed promising results by alleviating lameness; increased ALP, SOD, T-AOC, and GSH-Px levels; and decreased the AST, ALT, and MDA levels significantly. It restored the size of the growth plate and significantly up-regulated the BMP-2 and RUNX-2 expressions (p < 0.05). In conclusion, the oxidative stress and growth plate anomalies could be assuaged using osthole.

Abstract
Tamoxifen (TMX) is an antiestrogen drug that is used in the treatment and prevention of all stages of estrogen-dependent breast cancer. Adverse effects of TMX include hepatotoxicity. In this study, we investigated the therapeutic effects of osthole, isolated from medicinal plants especially Fructus Cnidii, on TMX-induced acute liver injury in mice. Mice were injected with osthole (100 mg/kg, ip) or vehicle, followed by TMX (90 mg/kg, ip) 24 h later. We showed that a single injection of TMX-induced liver injury and oxidative stress. Pretreatment with osthole attenuated TMX-induced liver injury evidenced by dose-dependent reduction of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities. Pretreatment with osthole also blunted TMX-induced oxidative stress, evidenced by significant increase of reduced glutathione (GSH) as well as reduction of malondialdehyde (MDA) and hydrogen peroxide (H2O2). Consistently, osthole significantly enhanced the expressions of antioxidant genes (GPX1, SOD2, GCL-c, and G6pdh), but suppressed those of pro-oxidant genes (NOX2 and ACOX). Furthermore, osthole inhibited the production of inflammatory cytokines, reduced the metabolic activation of TMX, and promoted its clearance. We further revealed that osthole elevated hepatic cAMP and cGMP levels, but inhibition of PKA or PKG failed to abolish the hepatoprotective effect of osthole. Meanwhile, prominent phosphorylation of p38 was observed in liver in response to TMX, which was significantly inhibited by osthole. Pretreatment with SB203580, a p38 inhibitor, significantly attenuated TMX-induced increase of ALT and AST activities, reduced oxidative stress, and reversed the alterations of gene expression caused by TMX. Moreover, pretreatment with L-buthionine sulfoximine (BSO), an inhibitor of GSH synthesis, partly reversed the effect of osthole on TMX-induced liver injury. Consistently, pretreatment with N-acetyl-L-cysteine (NAC) significantly attenuated TMX-induced increase in ALT and AST activities. Notably, both BSO and NAC had no detectable effect on the phosphorylation levels of p38. Collectively, our results suggest that osthole prevents TMX hepatotoxicity by suppressing p38 activation and subsequently reducing TMX-induced oxidative damage.

Osthole prevents acetaminophen-induced liver injury in mice. Acta Pharmacol Sin 2018; 39:74-84.

Abstract
Acetaminophen (APAP) overdose leads to severe hepatotoxicity. Osthole, a natural coumarin found in traditional Chinese medicinal herbs, has therapeutic potential in the treatment of various diseases. In this study, we investigated the effects of osthole against APAP-induced hepatotoxicity in mice. Mice were administered osthole (100 mg·kg-1·d-1, ip) for 3 d, then on the fourth day APAP (300 mg/kg, ip) was co-administered with osthole. The mice were euthanized post-APAP, their serum and livers were collected for analysis. Pretreatment with osthole significantly attenuated APAP-induced hepatocyte necrosis and the increases in ALT and AST activities. Compared with the mice treated with APAP alone, osthole pretreatment significantly reduced serum MDA levels and hepatic H2O2 levels, and improved liver GSH levels and the GSSG-to-GSH ratio. Meanwhile, osthole pretreatment markedly alleviated the APAP-induced up-regulation of inflammatory cytokines in the livers, and inhibited the expression of hepatic cytochrome P450 enzymes, but it increased the expression of hepatic UDP-glucuronosyltransferases (UGTs) and sulfotransferases (SULTs). Furthermore, osthole pretreatment reversed APAP-induced reduction of hepatic cAMP levels, but pretreatment with H89, a potent selective PKA inhibitor, failed to abolish the beneficial effect of osthole, whereas pretreatment with L-buthionine sulfoximine, a GSH synthesis inhibitor, abrogated the protective effects of osthole on APAP-induced liver injury, and abolished osthole-caused alterations in APAP-metabolizing enzymes. In cultured murine primary hepatocytes and Raw264.7 cells, however, osthole (40 μmol/L) did not alleviate APAP-induced cell death, but it significantly suppressed APAP-caused elevation of inflammatory cytokines. Collectively, we have demonstrated that osthole exerts a preventive effect against APAP-induced hepatotoxicity by inhibiting the metabolic activation of APAP and enhancing its clearance through an antioxidation mechanism.

Abstract
Renal cell carcinoma (RCC) is a common urinary malignancy that is resistant to chemotherapy and radiotherapy. Osthole, a monomer compound extracted from a traditional Chinese herb, has potent anti-tumor effects on various types of cancer cells. However, the therapeutic effects of osthole on RCC remain unclear. In our study, osthole could suppress the proliferation and colony formation of two RCC cell lines, ACHN and 786-O cells, in a dose-dependent manner. Treatment with osthole resulted in a significant, dose-dependent increase in the expression of pro-apoptotic proteins (cleaved caspase-3 and Bax) and decreased expression of anti-apoptotic proteins (Bcl-2 and survivin), which were consistent with evidence of apoptotic nuclear morphology revealed by DAPI staining. Pre-treatment with osthole attenuated the migratory and invasive abilities of RCC cells in a dose-dependent manner, as evidenced by a reduction in migrating cells in a Transwell assay and a decreased wound closure ratio in a scratch assay as compared with the control. Additionally, osthole down-regulated the expression of migration/invasion-related proteins matrix metalloproteinase (MMP)-2 and MMP-9. Osthole significantly up-regulated epithelial biomarkers (E-cadherin and beta-catenin) and down-regulated mesenchymal biomarkers (N-cadherin and vimentin). Furthermore, our results suggest that osthole suppressed the expression of epithelial-mesenchymal transition transcriptional factors Smad-3, Snail-1, and Twist-1. Taken together, the results of this study suggest that osthole might be a potential novel herbal agent against RCC.

Abstract
Osthole, a natural coumarin found in traditional Chinese medicinal plants, has shown multiple biological activities. In the present study, we investigated the preventive effects of osthole on inflammatory bowel disease (IBD). Colitis was induced in mice by infusing TNBS into the colonic lumen. Before TNBS treatment, the mice received osthole (100 mg·kg-1·d-1, ip) for 3 d. Pretreatment with osthole significantly ameliorated the clinical scores, colon length shortening, colonic histopathological changes and the expression of inflammatory mediators in TNBS-induced colitis. Pretreatment with osthole elevated serum cAMP levels; but treatment with the PKA inhibitor H89 (10 mg·kg-1·d-1, ip) did not abolish the beneficial effects of osthole on TNBS-induced colitis. In mouse peritoneal macrophages, pretreatment with osthole (50 μmol/L) significantly attenuated the LPS-induced elevation of cytokines at the mRNA level; inhibition of PKA completely reversed the inhibitory effects of osthole on IL-1β, IL-6, COX2, and MCP-1 but not on TNFα. In Raw264.7 cells, the p38 inhibitor SB203580 markedly suppressed LPS-induced upregulation of the cytokines, whereas the PKA inhibitors H89 or KT5720 did not abolish the inhibitory effects of SB203580. Moreover, in LPS-stimulated mouse peritoneal macrophages, SB203580 strongly inhibited the restored expression of IL-1β, IL-6, COX2, and MCP-1, which was achieved by abolishing the suppressive effects of osthole with the PKA inhibitors. Western blot analysis showed that osthole significantly suppressed the phosphorylation of p38, which was induced by TNBS in mice or by LPS in Raw264.7 cells. Inhibition of PKA partially reversed the suppressive effects of osthole on p38 phosphorylation in LPS-stimulated cells. Collectively, our results suggest that osthole is effective in the prevention of TNBS-induced colitis by reducing the expression of inflammatory mediators and attenuating p38 phosphorylation via both cAMP/PKA-dependent and independent pathways, among which the cAMP/PKA-independent pathway plays a major role.

Am J Physiol Gastrointest Liver Physiol 2017; 312:G427-G433. [PMID: 28254774 DOI: 10.1152/ajpgi.00440.2016] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2016] [Revised: 02/08/2017] [Accepted: 02/19/2017] [Indexed: 01/31/2023]
Abstract
Although melatonin attenuates the increases in inflammatory mediators and reduces organ injury during trauma-hemorrhage, the mechanisms remain unclear. This study explored whether melatonin prevents liver injury after trauma-hemorrhage through the p38 mitogen-activated protein kinase (MAPK)-dependent, inducible nitrite oxide (iNOS)/hypoxia-inducible factor (HIF)-1α pathway. After a 5-cm midline laparotomy, male rats underwent hemorrhagic shock (mean blood pressure ~40 mmHg for 90 min) followed by fluid resuscitation. At the onset of resuscitation, rats were treated with vehicle, melatonin (2 mg/kg), melatonin plus p38 MAPK inhibitor SB203580 (2 mg/kg), or melatonin plus the melatonin receptor antagonist luzindole (2.5 mg/kg). At 2 h after trauma-hemorrhage, histopathology score of liver injury, liver tissue myeloperoxidase activity, malondialdehyde, adenosine triphosphate, serum alanine aminotransferase, and asparate aminotransferase levels were significantly increased compared with sham-operated control. Trauma-hemorrhage resulted in a significant decrease in the p38 MAPK activation compared with that in the sham-treated animals. Administration of melatonin after trauma-hemorrhage normalized liver p38 MAPK phosphorylation and iNOS and HIF-1α expression and attenuated cleaved caspase 3 and receptor interacting protein kinase-1 levels. Coadministration of SB203580 or luzindole abolished the melatonin-mediated attenuation of the trauma-hemorrhage-induced increase of iNOS/HIF-1α protein expression and liver injury markers. Taken together, our results suggest that melatonin prevents trauma-hemorrhage-induced liver injury in rats, at least in part, through melatonin receptor-related, p38 MAPK-dependent iNOS/HIF-1α pathway.NEW & NOTEWORTHY Trauma-hemorrhage resulted in a significant decrease in liver p38 MAPK activation and increase in nitrite oxide synthase (iNOS) and hypoxia-inducible factor (HIF)-1α expression. Administration of melatonin after trauma-hemorrhage normalized liver p38 MAPK phosphorylation and iNOS and HIF-1α expression, which was abolished by coadministration of SB203580 or luzindole. Melatonin prevents trauma-hemorrhage-induced liver injury in rats via the melatonin receptor-related, p38 MAPK-dependent iNOS/HIF-1α pathway.

Abstract
Oxidative stress caused by neutrophils is an important pathogenic factor in trauma/hemorrhagic (T/H)-induced acute lung injury (ALI). Osthol, a natural coumarin found in traditional medicinal plants, has therapeutic potential in various diseases. However, the pharmacological effects of osthol in human neutrophils and its molecular mechanism of action remain elusive. In this study, our data showed that osthol potently inhibited the production of superoxide anion (O2(•-)) and reactive oxidants derived therefrom as well as expression of CD11b in N-formylmethionylleucylphenylalanine (FMLP)-activated human neutrophils. However, osthol inhibited neutrophil degranulation only slightly and it failed to inhibit the activity of subcellular NADPH oxidase. FMLP-induced phosphorylation of extracellular signal-regulated kinase (ERK) and protein kinase B (Akt) was inhibited by osthol. Notably, osthol increased the cAMP concentration and protein kinase A (PKA) activity in activated neutrophils. PKA inhibitors reversed the inhibitory effects of osthol, suggesting that these are mediated through cAMP/PKA-dependent inhibition of ERK and Akt activation. Furthermore, the activity of cAMP-specific phosphodiesterase (PDE) 4, but not PDE3 or PDE7, was significantly reduced by osthol. In addition, osthol reduced myeloperoxidase activity and pulmonary edema in rats subjected to T/H shock. In conclusion, our data suggest that osthol has effective anti-inflammatory activity in human neutrophils through the suppression of PDE4 and protects significantly against T/H shock-induced ALI in rats. Osthol may have potential for future clinical application as a novel adjunct therapy to treat lung inflammation caused by adverse circulatory conditions.

Abstract
Osthole, the active constituent of Cnidium monnieri extracts, has been shown to have a diverse range of pharmacological properties. In the present study, we aimed to evaluate the cardioprotective effects of osthole in a rat model of acute myocardial infarction (AMI). The rats with AMI were treated with 1, 3 and 10 mg/kg of osthole or the vehicle for 4 weeks. The infarct size of the rats with AMI was measured, and casein kinase (CK), the MB isoenzyme of creatine kinase (CK-MB), lactate dehydrogenase (LDH) and cardiac troponin T (cTnT) activities in the rats with AMI were analyzed using commercially available kits. The nuclear factor-κB (NF-κB), tumor necrosis factor‑α (TNF-α), interleukin (IL)-1β and IL-6 levels in whole blood from rats with AMI were also detected using commercially available kits. The levels of Toll-like receptors 2/4 (TLR2/4) and nucleotide-binding oligomerization domain-containing protein 1/2 (NOD1/2) were also detected by RT-qPCR. Moreover, the protein expression levels of endothelial nitric oxide synthase (eNOS) and mitogen-activated protein kinase (MAPK) cascades, including extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK) and p38, cyclooxygenase-2 (COX-2), as well as matrix metalloproteinase-2 (MMP-2) were all assayed by western blot analysis. Our results revealed that osthole markedly reduced the infarct size, and the levels of CK, CK-MB, LDH and cTnT in the rats with AMI, and that these cardioprotective effects may be associated with the inhibition of inflammatory reactions, the reduction in MMP-2 activity and the activation of MAPK cascades.

Abstract
Resveratrol (RSV) has been shown to inhibit the inflammatory reaction and ameliorate the organ damage resulting from trauma-hemorrhage (TH). However, the effects of RSV on the metabolomic profiles under these conditions remain unclear. The aim of this study was to determine the metabolomic profiles of plasma in TH rats and to evaluate the therapeutic effects of RSV using high-performance liquid chromatography-mass spectrometry. Thirty male Sprague-Dawley rats were divided into sham operation (n = 10), sham-operation plus RSV treatment (n = 10), TH (n = 10), and TH plus RSV treatment (n = 10) groups. Plasma samples were obtained at 24 h after surgery. Electrospray ionization-tandem mass spectrometry was used to characterize the plasma metabolomes. The systemic analyses of plasma metabolomes and their targets were determined using a number of computational approaches, including principal component analysis, partial least squares discriminant analysis, and heat map analysis. Using these methods, the effects of RSV on the metabolomic profiles in animals that underwent trauma-hemorrhagic injury were determined. These approaches allowed a clear discrimination of the pathophysiological characteristics among the groups. The results demonstrate RSV treatment significantly reduced the metabolic derangements caused by TH. Compared with the sham-operated rats, the plasma levels of carnitine in the TH rats were relatively lower, but the levels of acetylcarnitine and butyrylcarnitine were higher, suggesting that RSV ameliorated the deranged carnitine metabolism in TH rats. There was a statistically significant increase in carnitine. In addition, RSV treatment reduced ketoacidosis and protein degradation, as evidenced by the attenuation of the elevated plasma branched-chain amino acid levels in the TH rats. Our study showed that the alterations of the metabolomic profiles in the rats subjected to trauma-hemorrhagic shock were attenuated by RSV treatment. In view of the metabolomic evidence, we conclude that RSV exerts beneficial effects in trauma-hemorrhagic shock injury and that these effects are partially mediated by improving energy metabolism and reducing protein degradation.

Int J Clin Exp Med 2015; 8:8854-8859. [PMID: 26309539 PMCID: PMC4538101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2015] [Accepted: 04/23/2015] [Indexed: 06/04/2023]
Abstract
Acute myocardial infarction (AMI) is the myocardial necrosis caused by coronary artery acute and persistent ischemia and hypoxia. Matrix metalloprotease-9 (MMP-9) plays an important role in a series of process of occurrence and development of AMI. Inflammatory reaction plays the key role in all kinds of damage factors in AMI. Apigenin (API) has effectively restrained the activity of MMP-9, anti-inflammatory and hepatic fat oxidizing properties. API significantly improved AMI of rats through inhibiting MMP-9 and inflammatory reactions in a few recent studies. Our investigation detected the infarct size of AMI rats, casein kinase (CK), the MB isoenzyme of creatine kinase (CK-MB) and lactate dehydrogenase (LDH) and cardiac troponin T (cTnT) activities in AMI rats were also analyzed with commercial kits. Additionally, Nuclear factor kappa B (NF-κB), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) levels of whole bloods of AMI rats were also detected using commercial kits. Next, MMP-9 protein of cardiac in AMI rats was measured with gelatin zymography assays. Finally, caspase-3 and caspase-9 activities in AMI rats were analyzed with commercial kits. In the present study, our work indicated API might significantly reduce the infarction size of AMI rat. It was shown that the treatment of API could decrease the expression of MMP-9 level and reduce the activities of NF-κB, TNF-α, IL-1β and IL-6 in AMI rats. Next, API treatment could reduce caspase-3 and caspase-9 activities and decrease cellular apoptosis of AMI rats. Our findings concluded that API ameliorates acute myocardial infarction of rats via inhibiting MMP-9 and inflammatory reactions.

Abstract
Neutrophil activation is associated with the development of organ injury after trauma-hemorrhagic shock. In the present study, ursolic acid inhibited the superoxide anion generation and elastase release in human neutrophils. Administration of ursolic acid attenuated trauma-hemorrhagic shock-induced hepatic and lung injuries in rats. In addition, administration of ursolic acid attenuated the hepatic malondialdehyde levels and reduced the plasma aspartate aminotransferase and alanine aminotransferase levels after trauma-hemorrhagic shock. In conclusion, ursolic acid, a bioactive natural compound, inhibits superoxide anion generation and elastase release in human neutrophils and ameliorates trauma-hemorrhagic shock-induced organ injury in rats.

Liu FC, Tsai YF, Yu HP. Maraviroc attenuates trauma-hemorrhage-induced hepatic injury through PPAR gamma-dependent pathway in rats. PLoS One 2013; 8:e78861. [PMID: 24205332 PMCID: PMC3799750 DOI: 10.1371/journal.pone.0078861] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2013] [Accepted: 09/19/2013] [Indexed: 01/02/2023] Open
Abstract
Maraviroc is a CC-chemokine receptor 5 (CCR5) antagonist with potent antiviral and cancer preventive effects. Recent evidence suggests that the co-existence of CCR5 in various cell types is involved in inflammation. However, the effects that CCR5 antagonists produce in trauma-hemorrhage remain unknown. The peroxisome proliferator-activated receptor gamma (PPARγ) pathway exerts anti-inflammatory effects in injury. In this study, we hypothesized that maraviroc administration in male rats, after trauma-hemorrhage, decreases cytokine production and protects against hepatic injury through a PPARγ-dependent pathway. Male Sprague-Dawley rats underwent trauma-hemorrhage (mean blood pressure maintained at approximately 35-40 mmHg for 90 minutes), followed by fluid resuscitation. During resuscitation, a single dose of maraviroc (3 mg/kg, intravenously) with and without a PPARγ antagonist GW9662 (1 mg/kg, intravenously), GW9662 or vehicle was administered. Plasma alanine aminotransferase (ALT) with aspartate aminotransferase (AST) concentrations and various hepatic parameters were measured (n=8 rats/group) at 24 hours after resuscitation. The results showed that trauma-hemorrhage increased hepatic myeloperoxidase activity, intercellular adhesion molecule-1 and interleukin-6 levels, and plasma ALT and AST concentrations. These parameters were significantly improved in the maraviroc-treated rats subjected to trauma-hemorrhage. Maraviroc treatment also increased hepatic PPARγ expression compared with vehicle-treated trauma-hemorrhaged rats. Co-administration of GW9662 with maraviroc abolished the maraviroc-induced beneficial effects on the above parameters and hepatic injury. These results suggest that the protective effect of maraviroc administration on alleviation of hepatic injury after trauma-hemorrhage, which is, at least in part, through PPARγ-dependent pathway.
