Antioxidants (Basel) 2023; 12:antiox12050997. [PMID: 37237862 DOI: 10.3390/antiox12050997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 04/14/2023] [Accepted: 04/21/2023] [Indexed: 05/28/2023] Open
Abstract
Atherogenesis involves multiple cell types undergoing robust metabolic processes resulting in mitochondrial dysfunction, elevated reactive oxygen species (ROS), and consequent oxidative stress. Carbon monoxide (CO) has been recently explored for its anti-atherogenic potency; however, the effects of CO on ROS generation and mitochondrial dysfunction in atherosclerosis remain unexplored. Herein, we describe the anti-atherogenic efficacy of CORM-A1, a CO donor, in in vitro (ox-LDL-treated HUVEC and MDMs) and in vivo (atherogenic diet-fed SD rats) experimental models. In agreement with previous data, we observed elevated miR-34a-5p levels in all our atherogenic model systems. Administration of CO via CORM-A1 accounted for positive alterations in the expression of miR-34a-5p and transcription factors/inhibitors (P53, NF-κB, ZEB1, SNAI1, and STAT3) and DNA methylation pattern, thereby lowering its countenance in atherogenic milieu. Inhibition of miR-34a-5p expression resulted in restoration of SIRT-1 levels and of mitochondrial biogenesis. CORM-A1 supplementation further accounted for improvement in cellular and mitochondrial antioxidant capacity and subsequent reduction in ROS. Further and most importantly, CORM-A1 restored cellular energetics by improving overall cellular respiration in HUVECs, as evidenced by restored OCR and ECAR rates, whereas a shift from non-mitochondrial to mitochondrial respiration was observed in atherogenic MDMs, evidenced by unaltered glycolytic respiration and maximizing OCR. In agreement with these results, CORM-A1 treatment also accounted for elevated ATP production in both in vivo and in vitro experimental models. Cumulatively, our studies demonstrate for the first time the mechanism of CORM-A1-mediated amelioration of pro-atherogenic manifestations through inhibition of miR-34a-5p expression in the atherogenic milieu and consequential rescue of SIRT1-mediated mitochondrial biogenesis and respiration.

Abstract
Background Zhijing Powder (ZJP) is a traditional Chinese medicine containing two kinds of Chinese medicine. Those studies analyze the molecular mechanism of ZJP in treating hypertension through network pharmacology, combined with animal experiments. Methods First, the effective ingredients and potential targets of the drug were obtained through drug databases, while the targets of disease obtained through disease target databases. The potential targets, cellular bioanalysis and signaling pathways were found in some platforms by analyzing collected targets. Further experiments were conducted to verify the effect and mechanism of drugs on cold and high salt in an induced-hypertension rat model. Results There are 17 effective components of centipedes and 10 of scorpions, with 464 drug targets obtained after screening. A total of 1263 hypertension targets were obtained after screening and integration, resulting in a protein-protein interaction network (PPI) with 145 points and 1310 edges. Gene ontology (GO) analysis shows that blood circulation regulation and activation of G protein-coupled receptors are mainly biological processes. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis shows that neuroactive ligand-receptor interaction, calcium signaling pathways, PI3K-AKT signaling pathways are the most abundant gene-enriched pathway. Animal experiments indicated that ZJP can reduce blood pressure (BP), affect expression of the PI3K-AKT signaling pathway, and improve oxidative stress in the body. Conclusion ZJP ameliorates oxidative stress and reduces BP in hypertensive rats caused by cold stimuli and high salt, revealing its effect on the expression of the PI3K/AKT signaling pathway in the rat aorta.

Abstract
Venoms are a complex cocktail of biologically active molecules, including peptides, proteins, polyamide, and enzymes widely produced by venomous organisms. Through long-term evolution, venomous animals have evolved highly specific and diversified peptides and proteins targeting key physiological elements, including the nervous, blood, and muscular systems. Centipedes are typical venomous arthropods that rely on their toxins primarily for predation and defense. Although centipede bites are frequently reported, the composition and effect of centipede venoms are far from known. With the development of molecular biology and structural biology, the research on centipede venoms, especially peptides and proteins, has been deepened. Therefore, we summarize partial progress on the exploration of the bioactive peptides and proteins in centipede venoms and their potential value in pharmacological research and new drug development.

Correlation between decreased plasma miR-29a and vascular endothelial injury induced by hyperlipidemia. Herz 2022:10.1007/s00059-022-05121-x. [PMID: 35674773 DOI: 10.1007/s00059-022-05121-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Revised: 02/14/2022] [Accepted: 04/22/2022] [Indexed: 11/04/2022]
Abstract
BACKGROUND Hyperlipidemia is a major risk factor for vascular endothelial injury and atherosclerosis leading to cardiovascular diseases. Early diagnosis of vascular endothelial injury is important for the prevention and prognosis of cardiovascular diseases. This study aimed to investigate sensitive circulating microRNA (miRNA) as a potential diagnostic biomarker of vascular endothelial injury in a hyperlipidemic rat model. METHODS The miRNA expression profile was detected by miRNA microarray. The hyperlipidemic rat model was established by intraperitoneal injection of vitamin D3 combined with a high-fat diet. Plasma miRNA levels were measured by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR). RESULTS No significant difference was found in the types of highly expressed miRNAs between human umbilical artery endothelial cells (HUAEC) and human umbilical vein endothelial cells (HUVEC). A total of 10 highly expressed miRNAs in endothelial cells were selected as candidate miRNAs, including miR-21, miR-126, let-7a, miR-23a, miR-221, miR-125b, miR-26a, miR-29a, miR-16, and miR-100. The plasma levels of let-7a, miR-126, miR-21, and miR-26a were significantly elevated in hyperlipidemic rats at 30 and 50 days after modeling, while the plasma level of miR-29a was significantly decreased. No significant change was found in the plasma levels of miR-125b, miR-23a, miR-221, miR-100, and miR-16. Interestingly, a significant reduction in plasma miR-29 level was detected as early as 20 days after modeling, which was earlier than for soluble intercellular adhesion molecule‑1 (sICAM-1). CONCLUSION The plasma levels of endothelial cell-enriched miRNAs were correlated with vascular endothelial injury induced by hyperlipidemia. miR-29a might serve as a potential early diagnostic biomarker of endothelial injury-related diseases.

Abstract
OBJECTIVE To investigate the effect of atorvastatin on the expression of lectin- like oxLDL receptor 1 (LOX-1) and endothelial nitric oxide synthase (eNOS) in collateral vessels of hypercholesterolemic rats. METHODS Forty male SD rats were randomized equally into 4 groups: femoral ligation group (L), hypercholesterolemia + femoral ligation group (HL), hypercholesterolemia+atorvastatin+femoral ligation group (AL), and hypercholesterolemia+normal saline+femoral ligation group (NL). The rats in the latter 3 groups were fed atherogenic diet for 8 weeks. At the end of the 8 weeks, the rats were subjected to femoral artery ligation with or without intraperitoneal injection of atorvastatin (AL group) or saline (NL group). Two weeks later, all the rats were euthanized and the expressions of LOX-1 and eNOS in the collateral vessels were detected with immunofluorescence assay. In the in vitro experiment, cultured human umbilical vein endothelial cells (HUVECs) were transfected with LOX-1 siRNA followed by treatment with oxLDL and/or atorvastatin. The expressions of LOX-1 and eNOS in the cells were detected with realtime PCR and Western blotting, and the cellular NO production was examined with Griess assay. RESULTS The collateral vessels of rats with normal feeding expressed LOX-1, which was significantly increased in the collateral vessels of hypercholesterolemic rats; atorvastatin treatment significantly lowered LOX-1 expressions in the hypercholesterolemic rats. In normally fed rats, the growing collateral vessels exhibited strong eNOS expressions, which were lowered in hypercholesterolemic rats and enhanced after atorvastatin treatment. In the cell experiment, HUVECs with oxLDL treatment showed a high LOX-1 expression and a low eNOS expression, and atorvastatin treatment of the cells down-regulated LOX-1 and up-regulated eNOS expressions. Inhibition of LOX-1 mediated by a specific LOX-1 siRNA abolished the effect of oxLDL stimulation on eNOS expression in the cells. CONCLUSIONS Both hypercholesterolemia and oxLDL can induce endothelial dysfunction and impair collateral vessel growth via the LOX-1/eNOS pathway in rats, and atorvastatin treatment can restore the LOX-1/eNOS pathway to promote the growth of the collateral vessels, suggesting the potential of atorvastatin as a therapeutic agent to promote repair of collateral vessel injuries in ischemic diseases.

Abstract
(Scolopendra subspinipes mutilans L. Koch. (SSLK) helps reduce the risk of coronary heart disease (CHD) but its effects on rheumatic heart disease (RHD) patients remain unclear. 80 RHD patients were recruited and randomly assigned into SG (to receive SSLK treatment) and CG (to receive placebo) groups, and the intervention lasted for 3 months. The following cardiac indexes were measured, including mean arterial pressure (MAP), heart rate (HR), central venous pressure (CVP), blood lactate, fatigue, shortness of breath, palpitation, and chest pain. ELISA kits were used to analyze creatine kinase isoenzyme (CK-MB), serum troponin T (cTnT), CRP, IL-1β, IL-6, and TNF-α, malondialdehyde (MDA), and superoxide dismutase (SOD). Relative percentages of CD4+CD25+FoxP3 regulatory (Treg) and CD4+IL-17 T cells were measured using flow cytometry. After 3-month therapy, SSLK intervention improved MAP, HR, CVP, fatigue, palpitation, and shortness breath of CHD patients, reduced the levels of blood lactate, CK-MB, cTnT, CRP, IL-1β, IL-6, TNF-α, MDA, and increased SOD level (p < 0.05). Meanwhile, SSLK treatment increased the percentages of CD4+CD25+FoxP3 Treg cells and reduced relative percentages of CD4+IL-17 T cells in a dose-dependent way (p < 0.05). Relative percentage of CD4+CD25+FoxP3 Treg cells had negative relationship while CD4+IL17 T cells had positive relationship with CK-MB, cTnT, CRP, and TNF-a (p < 0.01). SSLK ameliorated RHD by affecting the balance of CD4+CD25+FoxP3 Treg and CD4+IL17 T cells.

Shen-Yuan-Dan Capsule Attenuates Atherosclerosis and Foam Cell Formation by Enhancing Autophagy and Inhibiting the PI3K/Akt/mTORC1 Signaling Pathway. Front Pharmacol 2019; 10:603. [PMID: 31214032 PMCID: PMC6554665 DOI: 10.3389/fphar.2019.00603] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2018] [Accepted: 05/13/2019] [Indexed: 01/08/2023] Open
Abstract
Background and Aim: The phosphoinositide 3-kinase (PI3K)/Akt/mammalian target of rapamycin complex 1 (mTORC1) signaling pathway plays a crucial role in autophagy and inflammation. Our previous studies demonstrated that Shen-Yuan-Dan Capsule (SYDC), a Chinese medicine used for treating angina pectoris, has anti-atherosclerotic and anti-inflammatory effects in mice. However, its effects on autophagy and the PI3K/Akt/mTORC1 signaling pathway remain unclear. This study aimed to explore the effects of SYDC on autophagy and PI3K/Akt/mTORC1 signaling in the apolipoprotein E knockout (ApoE−/−) mouse model and in macrophage-derived foam cells to delineate the underlying mechanism. Methods: After 6 weeks of high-fat diet, ApoE–/– mice were randomly grouped into control, Lipitor, low-SYDC (SYDC-L), middle-SYDC (SYDC-M), and high-SYDC (SYDC-H) groups (n = 10). The mice were intragastrically administered the respective treatment for 6 weeks. Murine RAW264.7 cells were stimulated with oxidized low-density lipoprotein (ox-LDL) (80 µg/ml) for 24 h and then pretreated with SYDC freeze-dried powder for another 24 h. Cells treated with SYDC were co-cultured for 24 h with LY294002, tricirbine, and rapamycin to investigate the effects on the PI3K/Akt/mTORC1 signaling pathway. Results: SYDC ameliorated blood lipid levels, reduced the atherosclerotic index and plaque areas in the aortic root in mice, and inhibited total cholesterol (TC) levels and cholinesterase (ChE)/TC ratios in ox-LDL stimulated macrophages. Moreover, SYDC up-regulated Beclin1 and LC3II/I proteins in mice and in the ox-LDL–stimulated macrophages. Moreover, SYDC inhibited AKT phosphorylation at Ser473 and mTOR phosphorylation at Ser2448 in mice and in ox-LDL–stimulated macrophages. Furthermore, SYDC’s inhibitory of ChE/TC ratios in ox-LDL–stimulated macrophages was not changed by selective inhibition of the PI3K/Akt/mTORC1 pathway. Conclusions: Our results highlight that SYDC treatment attenuates foam cell formation by promoting autophagy via inhibiting activation of the PI3K/Akt/mTORC1 signaling pathway. This study provides new insights into the molecular mechanism underlying SYDC’s therapeutic potential for treating atherosclerosis.

Abstract
Background Sciatic nerve injury develops from a variety of pathological causes, including traumatic injury and neuroinflammatory disorders, which are accompanied by pathological changes that have a critical impact on neuropathic pain and locomotor activity. Extracts of Scolopendra subspinipes mutilans (SSM) are used in traditional medicine for the treatment of a wide range of neuropathic diseases, including lower back pain, peripheral neuropathy, and sciatic nerve injury. Although SSM shows anti-inflammatory, antibacterial, and anticonvulsant activities, its diverse mechanisms of action remain unclear. Thus, the present study examined the effects of SSM in vitro and in vivo. Methods To estimate the anti-inflammatory effects of SSM, inflammatory conditions were induced using lipopolysaccharide (LPS) in RAW 264.7 cells, and inflammatory-related factors were evaluated by enzyme-linked immunosorbent assay (ELISA) and western blotting analyses. Sciatic nerve crush injury (SNCI) was induced in rats using a surgical clip instrument. The effects of SSM in the SNCI model were evaluated in behavioral tests by calculating the sciatic functional index (SFI) and measuring thermal hyperalgesia sensitivity and by monitoring inflammatory factors expression in western blotting analyses. Results We observed the anti-inflammatory effects of SSM treatment both in vitro and in vivo. The PGE2 and NO production were suppressed by SSM. Protein analyses indicated that expression of NF-κB and degradation of IκBα were suppressed by SSM treatment. In addition, the levels of iNOS, TNF-α, IL-6, and COX-2 expression were reduced by SSM treatment in RAW 264.7 cells and in the SNCI-induced animals. In behavioral studies, SSM treatment enhanced the SFI and improved the thermal sensitivity test results. Conclusions Our results suggest that SSM suppresses the production of inflammatory factors via the NF-κB pathway and accelerates the morphological and functional recovery of the peripheral nervous system. Hence, SSM may be a useful therapeutic candidate for treatment of neuropathic pain diseases.

Effect of Tetramethylpyrazine on Atherosclerosis and SCAP/SREBP-1c Signaling Pathway in ApoE -/- Mice Fed with a High-Fat Diet. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 2017:3121989. [PMID: 28491104 PMCID: PMC5405370 DOI: 10.1155/2017/3121989] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/21/2016] [Revised: 02/27/2017] [Accepted: 02/27/2017] [Indexed: 12/03/2022]
Abstract
Lipid metabolism dysregulation plays a crucial role in the occurrence of atherosclerosis (As). SCAP/SREBP signaling is the main pathway for regulating lipid metabolism. Tetramethylpyrazine (TMP), a Traditional Chinese Medicine (TCM) for treating angina pectoris, has antiatherosclerotic effects and ameliorates blood lipids disturbance. However, its precise mechanism remains unclear. This study investigated the mechanism of TMP in ameliorating As in mice model. After six weeks of high-fat diet, 30 ApoE−/− mice were randomized (n = 10) and treated with Lipitor, TMP, or distilled water for six weeks. The serum blood lipids and insulin levels were measured. The expressions of PAQR3, Insig-1, SCAP, SREBP-1c, IRS-1, PI3K, Akt, and mTORC-1 in the adipose tissues were determined. The results showed that TMP could significantly decrease blood lipids levels, insulin, and corrected plaque area of the ApoE−/− mice as compared to the untreated mice (P < 0.05, P < 0.01). Moreover, TMP could significantly downregulate the expressions of SCAP, SREBP-1c, PAQR3, IRS-1, PI3K, Akt, and mTORC1 (P < 0.01). Thus, TMP may ameliorate lipid metabolism disorder and As by downregulating PAQR3 and inhibiting SCAP/SREBP-1c signaling pathway. In addition, PI3K/Akt/mTORC1 signaling pathway may be involved in this process.

Abstract
BACKGROUND Atherosclerosis is the leading cause of death worldwide. there are no effective approaches to regressing atherosclerosis due to not fully understood mechanisms. Recently, stem cell-based therapies have held promises to various diseases, including vascular diseases. AIM The present study aimed at investigating the possible effect of cord blood mesenchymal stem cell (MSC) therapy on atherosclerosis. MATERIAL AND METHODS Eighty adult male albino rats were divided into control group (I), atherogenic group (II): subjected to high cholesterol fed diet (200~300 mg/kg body weight) for 12 weeks and 1.8 million units of vitamin D / kg of diet for 6 weeks. Stem cell therapy group (III): injected with stem cells in the tail vein following confirmation of atherosclerosis. Histological, Immunohistochemical and morphometric studies were performed were conducted. RESULTS Atherogenic group (II) showed increased aortic thickness, intimal proliferation, smooth muscle proliferation and migration. Increased area % of collagen fibers, iNOS and vimentin immunoreactions were recorded and proved morphometrically. All findings regressed on stem cell therapy. CONCLUSION A definite therapeutic effect of mesenchymal stem cells was found on atherosclerosis.

Abstract
Venomous animals have evolved with sophisticated bio-chemical strategies to arrest prey and defend themselves from natural predators. In recent years, peptide toxins from venomous animals have drawn considerable attention from researchers due to their surprising chemical, biochemical, and pharmacological diversity. Similar to other venomous animals, centipedes are one of the crucial venomous arthropods that have been used in traditional medicine for hundreds of years in China. Despite signifying pharmacological importance, very little is known about the active components of centipede venoms. More than 500 peptide sequences have been reported in centipede venomous glands by transcriptome analysis, but only a small number of peptide toxins from centipede has been functionally described. Like other venomous animals such as snakes, scorpions, and spiders, the venom of centipedes could be an excellent source of peptides for developing drugs for treatments as well as bio-insecticides for agrochemical applications. Although centipede venoms are yet to be adequately studied, the venom of centipedes as well as their components described to date, should be compiled to help further research. Therefore, based on previous reports, this review focusses on findings and possible therapeutic applications of centipede venoms as well as their components.

Abstract
Scolopendra extracts were used for pharmacopuncture at the Kidney 1 acupoint to investigate the role of Scolopendra pharmacopuncture (SPP) in both the development and maintenance of neuropathic pain induced by L5 spinal nerve ligation in rats and the contribution of spinal glial cells. A single treatment and five once-daily treatments with SPP were given to evaluate its effects on the development and maintenance stages of neuropathic pain, respectively, which was followed by behavioral tests. Immunohistochemistry and Western blotting tests were also carried out. A single treatment of SPP delayed spinal nerve ligation-induced mechanical allodynia and thermal hyperalgesia and induced a profound decrease in the expression of ionized calcium binding adaptor protein in the lumbar spinal cord. Repeated SPP treatments reliably suppressed mechanical allodynia and thermal hyperalgesia at later time points, and these results correlated mainly with decreases in glial fibrillary acidic protein. Intriguingly, ionized calcium binding adaptor protein expression was also reduced after repeated SPP. These results illustrate that neuropathic pain in the development and maintenance stages is alleviated by SPP treatment, which may be ascribed principally to deactivations of microglia and astroglia, respectively. Additionally, microglial inactivation seems to be partially involved in preventing neuropathic pain in the maintenance stage.

Abstract
Centipedes have been used as traditional medicine for thousands of years in China. Centipede venoms consist of many biochemical peptides and proteins. Factor Xa (FXa) is a serine endopeptidase that plays the key role in blood coagulation, and has been used as a new target for anti-thrombotic drug development. A novel FXa inhibitor, a natural peptide with the sequence of Thr-Asn-Gly-Tyr-Thr (TNGYT), was isolated from the venom of Scolopendra subspinipesmutilans using a combination of size-exclusion and reverse-phase chromatography. The molecular weight of the TNGYT peptide was 554.3 Da measured by electrospray ionization mass spectrometry. The amino acid sequence of TNGYT was determined by Edman degradation. TNGYT inhibited the activity of FXa in a dose-dependent manner with an IC50 value of 41.14 mg/ml. It prolonged the partial thromboplastin time and prothrombin time in both in vitro and ex vivo assays. It also significantly prolonged whole blood clotting time and bleeding time in mice. This is the first report that an FXa inhibiting peptide was isolated from centipedes venom.

Abstract
High-density lipoprotein (HDL) is a key mediator in reverse cholesterol transport and is involved in a mechanism known as 'selective lipid uptake', a process mediated by scavenger receptor B type I (SR‑BI), which is a HDL receptor. The aim of the present study was to investigate the therapeutic effect of the SR‑BI gene when delivered by combining cationic liposomal microbubbles (CLMs) and ultrasound (US) in hypercholesterolemic rats. Hypercholesterolemia was induced by administration of excessive doses of vitamin D3 and cholesterol in rats. The CLMs consisted of perfluoropropane gas encapsulated in a phospholipid shell using the sonication‑lyophilization method. The SR‑BI gene, mixed with the self‑made microbubbles, was transfected into hypercholesterolemic rat arteries using therapeutic US. SR‑BI protein expression was determined by western blot analysis 2 days post-transfection. Two weeks after transfection, total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL) and HDL serum concentrations were measured. Transfection efficiency of the SR‑BI gene in the SR‑BI + US/CLM group increased 6‑7‑fold compared with the SR‑BI group. Two weeks after transfection, plasma lipid levels in treated hypercholesterolemic rats were observed to be significantly reduced compared with rats that did not receive treatment. However, no significant change was observed in the SR‑BI group compared with that in the SR‑BI + US/CLM group. Results of the present study indicate that the combination of US and CLMs loaded with the SR‑BI gene may exert a protective role in hypercholesterolemia.

Abstract
Exposure to lead (Pb) can induce kidney damage, which is related to induction of oxidative damage and disturbance of intracellular calcium homeostasis. Pb can readily permeate through dihydropyridine-sensitive L-type calcium channels and accumulate within cells. The objective of this study was to investigate protective effects of calcium channel blockers (CCBs) verapamil and nimodipine on nephrotoxicity induced by Pb acetate in mice. One hundred and twenty male mice were randomly divided into 6 groups: control, Pb, low-dose verapamil, high-dose verapamil, low-dose nimodipine and high-dose nimodipine (n=20 per group). Pb acetate was injected intraperitoneally (i.p.) at 40 mg/kg body weight/day for 10 days to establish the Pb toxicity model. While control mice received saline, mice of the treated groups simultaneously received i.p. injections of verapamil or nimodipine daily for 10 days. Both verapamil and nimodipine showed protection against Pb-induced kidney injury, including alleviation of renal pathological damage and decreasing the level of Pb in kidney homogenate and extent of apoptosis in nephrocytes. Moreover, verapamil and nimodipine significantly down-regulated levels of blood urea nitrogen and creatinine in the serum. In addition, verapamil and nimodipine administration decreased malondialdehyde content and increased activities of super oxide dismutase activity and glutathione peroxidase in the kidney homogenate. The findings in the present study implicate the therapeutic potential of CCBs for Pb-induced nephrotoxicity, which were at least partly due to the decrease of Pb uptake and inhibition of lipid peroxidation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The centipede has been prescribed for the treatment of cardiovascular diseases in Korea, China and other Far Eastern Asian countries for several hundred years. MATERIALS AND METHODS A novel antithrombotic peptide was isolated from Scolopendra subspinipes mutilans using a combination of ultrafiltration, Sephadex G-50 column, Source 15Q anion exchange column and RP-HPLC C18 column. RESULTS The molecular mass of the purified peptide is 346Da measured by Electrospray Ionization Mass Spectrometry (ESI-MS). The primary structure of the peptide is Ser-Gln-Leu (SQL) determined by Edman degradation. SQL potently prolonged the activated partial thromboplastin time (aPTT), and inhibited platelet aggregation. CONCLUSIONS These results help to clarify the mechanism of the antithrombotic activity of the centipede for effective treatment of cardiovascular and cerebrovascular diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Danshen (Salvia miltiorrhiza) has been widely prescribed in traditional folk medicine for treatment of hepatic and cardiovascular diseases in China and other Asian countries for several hundred years. MATERIALS AND METHODS Sixty male mice were randomly divided into five groups: control, iron overload, low-dose Danshen (L-Danshen, 3g/kg/day), high-dose Danshen (H-Danshen, 6g/kg/day) and deferoxamine (DFO) groups (n=12 per group). Iron dextran was injected intraperitoneally (i.p.) at 50mg/kg body weight/day to establish the iron overload model. While control mice received saline, mice of the treated groups simultaneously received (i.p.) injections of L-Danshen, H-Danshen or DFO daily for 2 weeks. At the end of the experiment, changes in alanine aminotransferase (ALT) and aspartate aminotransferase (AST), glutathione peroxidase (GSH-Px), superoxide desmutase (SOD) and malondialdehyde (MDA) were measured, and histological changes were observed by Prussian blue or hematoxylin and eosin staining of the liver. Apoptosis was detected by terminal-deoxynucleotidyl transferase mediated nick end labeling. RESULTS Treatment of iron overloaded mice with either low or high doses of Danshen not only significantly attenuated the hepatic dysfunction (ALT/AST levels), decreased the content of MDA and increased the activities of GSH-Px and SOD, it also suppressed apoptosis in hepatocytes. Histopathological examination showed that treatment with Danshen reduced iron deposition and ameliorated pathological changes in the liver of iron overloaded mice. CONCLUSIONS Danshen demonstrated significant protective effects in the liver of iron overloaded mice, which were at least partly due to the decrease of iron deposition and inhibition of lipid peroxidation and hepatocyte apoptosis.

Abstract
The protective effect Tulbaghia violacea rhizomes (TVR) against derangements in serum lipid profile, tissue antioxidant enzyme depletion, endothelium dysfunction and histopathological changes in the aorta and liver of rats fed with an atherosclerogenic (Ath) diet (4% cholesterol, 1% cholic acid and 0.5% thiouracil) was investigated in this study. Co-treatment with the TVR extracts (250 and 500 mg/kg body weight for two weeks significantly (p < 0.05) protected against elevated serum triglyceride (TG), total cholesterol (TC), LDL-cholesterol, VLDL-cholesterol and decreased HDL-cholesterol in a dose-dependent manner when compared with the atherogenic control. The extracts also reduced (p < 0.05) elevated thiobabutric reacting substance (TBARS) and reversed endothelial dysfunction parameters (fibrinogen and total NO levels) and tissue antioxidant enzyme activities to near normal. The protective ability of the extract was confirmed by the significant (p < 0.05) reduction in the activities of serum markers of liver (LDH, AST, ALT, ALP, bilirubin) and kidney damage (creatinine and bilirubin) in extract-treated groups compared with the atherogenic control group. Also, histopathology evaluations of aorta sections revealed that the extracts protected against the development of fatty streak plaques (aorta) and fatty changes in hepatocytes. The observed activities of the extracts compared favorably with standard drug atorvastatin. Our study thus showed that the methanolic extract of TVR could protect against the early onset of atherosclerosis.

CG extract supplementation to atherogenic diet fed rats significantly prevented increment in serum cholesterol, triglycerides, and lipoproteins, markers of LDL-C oxidation, auto-antibody titer and aortic lipids. Also, LDL-C isolated from ATH+CG rats recorded mimimal aggregation and susceptibility to undergo ex vivo LDL-C oxidation. Microscopic evaluation of thoracic aorta of ATH+CG rats reveled prevention of atheromatous plaque formation, accumulation of lipid laden macrophages, calcium deposition, distortion/defragmentation of elastin, accumulation of macrophages and, down regulation of cell adhesion molecules (VCAM-1 and P-selectin) expression. Further, in vitro monocyte to macrophage differentiation was significantly attenuated in presence of CG extract (200 µg/mL). It can be concluded from the present study that, CG extract is capable of controlling induction of experimental atherosclerosis and warrants further scrutiny at the clinical level as a possible therapeutic agent.

[PMID: 19931584 DOI: 10.1016/j.peptides.2009.11.007] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2009] [Revised: 11/10/2009] [Accepted: 11/10/2009] [Indexed: 10/20/2022]
Abstract
Growth hormone-releasing peptides (GHRP) and ghrelin are synthetic and natural ligands of growth hormone secretagogue receptor (GHSR) respectively and are shown to exert protective actions on cardiac dysfunction. Because ghrelin has been reported to inhibit proinflammatory responses in human endothelium and GHSR has been identified in blood vessels, we hypothesized that GHRP could alleviate the development of atherosclerosis (As). Atherosclearosis was induced by a short period (4 days) of vitamin D(3) and chronic (three months) intragastric feeding of high fat emulsion (containing 0.5% propylthiouracil) in adult SD rats. Some As rats received chronic hexarelin (a variant of GHRP) injection (SC BID, 30 days) and normal rats received placebo as control. Significant atherosclerosis developed in animals fed with the emulsion. Serum total cholesterol and LDL-c increased, and HDL-c and aortic nitric oxide (NO) decreased significantly in As group. Hexarelin suppressed the formation of atherosclerotic plaques and neointima, partially reversed serum HDL-c/LDL-c ratio and increased the levels of serum NO and aortic mRNAs of eNOS, GHSR and CD36 in As rats. Hexarelin also decreased [(3)H]-TdR incorporation in cultured vascular smooth muscle cell (VSMC) and calcium sedimentation in aortic wall. Furthermore, foam cell formation induced by ox-LDL was decreased by hexarelin. In conclusion, hexarelin suppresses high lipid diet and vitamin D3-induced atherosclerosis in rats, possibly through upregulating HDL-c/LDL-c ratio, vascular NO production and downregulating the VSMC proliferation, aortic calcium sedimentation and foam cell formation. These novel anti-atherosclerotic actions of hexarelin suggest that the peptide might have a clinical potential in treating atherosclerosis.
