Abstract
OBJECTIVE Follicle-stimulating hormone (FSH) level changes may be another reason for increasing the risk of cardiovascular disease. In this study, we aimed to investigate the role of FSH in atherosclerosis and its underlying mechanism. METHODS ApoE-/- mice were divided into 4 groups, namely, the sham group, bilaterally orchidectomized group, FSH group, and testosterone-only group. Blood lipid and hormone levels were tested, aorta Oil Red O staining; the levels of NF-κB, Akt, eNOS, and FSH receptors in the aorta were measured by Western blotting. Expression of VCAM-1 was detected via Western blotting and immunohistochemical staining. Human umbilical vein endothelial cells (HUVECs) were used to induce endothelial injury model by adding FSH, and the levels of NF-κB, Akt, eNOS, and FSHR were tested in HUVECs. RESULTS FSH treatment exacerbated atherosclerotic lesions in ApoE-/- mice. Moreover, FSH could promote the expression of VCAM-1 protein in HUVECs, and this effect was possibly mediated by the activation of NF-κB, while NF-κB activation was further enhanced by the activation of the PI3K/Akt/eNOS pathway. FSH failed to activate Akt and NF-κB in the presence of the PI3K inhibitor LY294002 in HUVECs. CONCLUSION FSH promoted the development of atherosclerosis by increasing VCAM-1 protein expression via activating PI3K/Akt/NF-κB pathway.

Abstract
The purpose of this study was to investigate the influence of C1QL1 on atherosclerosis as well as the transcriptomic alteration of the aorta. While complement C1ql-like 1 (C1QL1) is one of the C1q/tumor-necrosis-factor-related protein (CTRP) family members, also known as CTRP14, and is synthesized and secreted mainly by the brain and adipose tissues, the functional properties of the C1QL1/CTRP14 protein outside the brain and adipocytes remain, however, unknown. In this regard, apolipoprotein E (ApoE) knockout (KO) mice were fed a Western diet and injected with adenovirus (Ad) green fluorescent protein or Ad-C1QL1 through the tail vein for 12 weeks. In contrast with the control cohort, the area of atherosclerotic plaque in ApoE KO mice overexpressing C1QL1 showed no significant difference, and the RNA sequence revealed that there were only 111 differentially expressed genes (DEGs) enriched in 26 signaling pathways of the mRNA profile in the aortic atherosclerosis lesions. This analysis also revealed the expression of several genes related to metabolism, organismal system, and human diseases such as type II diabetes, which are not associated with the formation of atherosclerosis in the aorta. These findings illustrate that C1QL1 is largely dispensable for atherosclerosis formation in ApoE-deficient mice and does not improve atherosclerotic plaque formation in the aorta.

Abstract
Propamocarb is a systemic carbamate fungicide used to fight diseases. The effect of propamocarb on the formation of atherosclerosis was evaluated in wild-type (WT) and ApoE knockout (ApoE-/-) mice. C57BL/6 J WT mice were fed control diet or high-fat diet (HFD) with 20 mg/L propamocarb in drinking water for 24 weeks. Propamocarb significantly increased the serum levels of triglyceride, cholesterol and low-density lipoprotein cholesterol while decreasing high-density lipoprotein cholesterol. Simultaneously, propamocarb facilitated lipid accumulation in the liver and increased the expression of cholesterol synthesis and transport genes in the liver and ileum. Lipid accumulation was observed in the aortic roots of the propamocarb-treated mice fed HFD, and similar results were also observed with whole aorta staining. In addition, propamocarb exposure significantly increased the mRNA levels of IL-1β, TNF-α, ICAM-1, and VCAM-1 in the aorta and the serum IL-1β, IL-6, and TNF-α levels in HFD groups treated with propamocarb. In ApoE-/- mice, the results were consistent with those obtained in WT mice after exposure to 20 mg/L propamocarb for 10 weeks. Meanwhile, propamocarb significantly increased the levels of CD36, NF-κB, VCAM-1 and ICAM-1 proteins in the aortas of ApoE-/- mice. Propamocarb further disrupted cholesterol metabolism and enhanced atherosclerosis and inflammatory responses much more substantially, indicating that propamocarb has the potential to accelerate the formation of atherosclerosis. An analysis of gut microbiota revealed that propamocarb altered the composition of gut microbiota in both WT and ApoE-/- mice. Interestingly, propamocarb increased the abundance of Peptostreptococcaceae, Ruminococcaceae, and Clostridiales_VadinBB60_group, which are related to atherosclerosis at the family level. The abundance of Paeniclostridium, Allobaculum, and Clostridioides, which are closely related to atherosclerosis, was also increased by propamocarb exposure. Our findings indicate that propamocarb exposure may promote atherosclerosis by disrupting lipid metabolism, increasing the inflammatory response, and altering the structure of gut microbiota.

Abstract
Mercury (Hg) is one of the most toxic environmental pollutants, especially when methylated, forming methylmercury (MeHg). MeHg affects DNA repair, increases oxidative stress, and predisposes to cancer. MeHg neurotoxicity is well-known, but recently MeHg-associated cardiovascular effects were recognized. This study evaluated circulating lipids, oxidative stress, and genotoxicity after MeHg-chronic exposure (20 mg/L in drinking water) in C57BL/6J wild-type and APOE knockout (ko) mice, the latter, being spontaneously dyslipidemic. Experimental mice were assigned to four groups: non-intoxicated and MeHg-intoxicated wild-type mice and non-intoxicated and MeHg-intoxicated APOE ko mice. Plasma levels of triglycerides, total cholesterol (TC), HDL, and LDL were analyzed. Liver lipid peroxidation and splenic gene expression of xeroderma pigmentosum complementation groups A, C, D, and G (XPA, XPC, XPD, and XPG), X-ray repair cross-complementing protein 1 (XRCC1), and telomerase reverse transcriptase (TERT) were measured. Fur Hg levels confirmed chronic MeHg intoxication. MeHg exposure raises TC levels both in wild-type and APOE ko mice. HDL and LDL-cholesterol levels were increased only in the MeHg-challenged APOE ko mice. MeHg increased liver lipid peroxidation, regardless of the genetic background. Unintoxicated APOE ko mice showed higher expression of TERT than all other groups. APOE deficiency increases XPA expression, regardless of MeHg intoxication. Furthermore, MeHg-intoxicated mice had more cytogenetic abnormalities, effect which was independent of APOE deficiency. More studies are needed to dissect the interactions between circulating lipids, MeHg intoxication, and DNA-repair pathways even at young age, interactions that likely play critical roles in cell senescence and the risk for chronic disorders later in life.

Abstract
Capsanthin is the main carotenoid compound in red paprika (Capsicum annuum L.). However, little is known about the beneficial effects of capsanthin in nonalcoholic fatty liver disease (NAFLD). In this study, the hepatoprotective activity of capsanthin was investigated in a mouse model of NAFLD. Apolipoprotein-E knockout mice were fed with normal diet, Western-type diet (WD, NAFLD model), WD with capsanthin (0.5 mg/kg of body weight/day, CAP), WD with capsanthin-rich extract (25 mg/kg of body weight/day; CRE), or WD with red paprika powder (25 mg/kg of body weight/day, RPP) for 12 weeks. The carotenoid content in CRE or RPP was analyzed using ultraperformance liquid chromatography. The capsanthin concentration in CRE was 2067 mg/100 g of dry weight, which was 63% of total carotenoids. The oral administration of CRE or capsanthin significantly reduced the WD-induced increase in body weight and lipid accumulation in the liver (vs. the RPP group). In addition, CRE or capsanthin significantly inhibited the WD-induced increase in cholesterol and low-density lipoprotein levels. Furthermore, CRE or capsanthin showed reduced levels of plasma alanine and aspartate aminotransferase (ALT and AST, respectively), suggesting a steatohepatitis protective effect. Capsanthin regulated mRNA levels of peroxisome proliferator-activated receptor alpha (Pparα), carnitine palmitoyltransferase 1A (Cpt1a), acyl-CoA oxidase 1 (Acox1), and sterol regulatory element binding protein-1c (Srebp1c), which are associated with hepatic fatty acid metabolism. Overall, our results suggest that the capsanthin of red paprika plays a protective role against hepatic steatosis/steatohepatitis in NAFLD.

Abstract
BACKGROUND/OBJECTIVES Curcuma zedoaria R. (Zingiberaceae) has been used to treat headache, fever, and hypertension-related symptoms in Asian countries, including Korea, China, and Japan. We investigated whether dietary intake of a C. zedoaria extract (CzE) affected atherosclerosis in vivo. MATERIALS/METHODS Apolipoprotein E-deficient (ApoE−/−) mice (n = 32) were fed a normal diet (ND), a high-cholesterol diet (HCD), an HCD containing CzE (100 mg/kg/day), or an HCD containing simvastatin (10 mg/kg/day) for 12 weeks. The anti-atherosclerotic effects were evaluated by observing changes in fatty streak lesions, immunohistochemical analysis, ex vivo fluorescence imaging, lipid profiles, and western blot analysis. RESULTS The CzE-fed group showed a 41.6% reduction of atherosclerosis. Furthermore, CzE significantly reduced the levels of serum triglyceride, high-density lipoprotein, the chemokine (C-X3-C-motif) ligand 1, the adhesion molecules vascular cell adhesion molecule-1, intracellular adhesion molecule-1, and E-selectin; down-regulation of tumor necrosis factor-α, interleukin-6, high mobility group box-1, and cathepsin levels in the aortic sinuses and aortas of ApoE−/− mice were also observed. CONCLUSIONS The results suggest that the inclusion of a water extract of C. zedoaria in a HCD is closely correlated with reducing the risk of vascular inflammatory diseases in an ApoE mouse model.

Abstract
Atherosclerosis (AS), the underlying cause of most cardiovascular events, is one of the most common causes of human morbidity and mortality worldwide due to the lack of an efficient strategy for targeted therapy. In this work, we aimed to develop an ideal biomimetic nanoparticle for targeted AS therapy. Methods: Based on macrophage "homing" into atherosclerotic lesions and cell membrane coating nanotechnology, biomimetic nanoparticles (MM/RAPNPs) were fabricated with a macrophage membrane (MM) coating on the surface of rapamycin-loaded poly (lactic-co-glycolic acid) copolymer (PLGA) nanoparticles (RAPNPs). Subsequently, the physical properties of the MM/RAPNPs were characterized. The biocompatibility and biological functions of MM/RAPNPs were determined in vitro. Finally, in AS mouse models, the targeting characteristics, therapeutic efficacy and safety of the MM/RAPNPs were examined. Results: The advanced MM/RAPNPs demonstrated good biocompatibility. Due to the MM coating, the nanoparticles effectively inhibited the phagocytosis by macrophages and targeted activated endothelial cells in vitro. In addition, MM-coated nanoparticles effectively targeted and accumulated in atherosclerotic lesions in vivo. After a 4-week treatment program, MM/RAPNPs were shown to significantly delay the progression of AS. Furthermore, MM/RAPNPs displayed favorable safety performance after long-term administration. Conclusion: These results demonstrate that MM/RAPNPs could efficiently and safely inhibit the progression of AS. These biomimetic nanoparticles may be potential drug delivery systems for safe and effective anti-AS applications.

Abstract
The current study was designed to investigate effect of copper administration on oxidative damage to the brain in ApoE−/− mice and to explore the putative neuroprotective effects rendered by apolipoprotein E (ApoE). Male C57BL/6 ApoE−/− and wild-type mice were randomly assigned into four groups, ApoE−/− mice wild-type mice treated with either copper or saline. Copper sulphate pentahydrate or saline (200 µl) were administered intragastrically daily for 12 weeks. Expression of malondialdehyde, superoxide dismutase (SOD), hemeoxygenase 1 (HO-1), and NAD(P)H: quinone oxidoreductase 1 (NQO1) were determined by a combination of biochemical assays. The concentration of copper in the brain of C57BL/6 mice and ApoE−/− mice treated by copper significantly increased compared with mice treated by saline (P=0.0099 and P=0.0443). Compared with the C57BL/6 mice treated by copper, the level of the ApoE−/− mice treated by copper was higher (P=0.018). TBARS and SOD activities or the expressions of NQO1 and HO-1 in the brain were not significantly different amongst the four experimental groups of mice. The relative value of NQO1/β-actin expression in the brain of the ApoE−/− mice was similar in both saline and copper administration experimental groups. However, Western blot analysis showed that NQO1 expression was significantly higher in the ApoE−/− mice brain treated with saline compared with saline treated wild-type mice (P=0.0449). ApoE does not function in protecting the brain from oxidative damage resulting from copper build-up in Wilson’s disease, but may play a role in regulating copper accumulation in the brain.

Abstract
Atherosclerosis is an inflammatory disease of arterial walls and the rupturing of atherosclerotic plaques is a major cause of heart attack and stroke. Imaging techniques that can enable the detection of atherosclerotic plaques before clinical manifestation are urgently needed. Magnetic resonance imaging (MRI) is a powerful technique to image the morphology of atherosclerotic plaques. In order to better analyze molecular processes in plaques, contrast agents that can selectively bind to plaque receptors will prove invaluable. CD44 is a cell surface protein overexpressed in plaque tissues, the level of which can be correlated with the risks of plaque rupture. Thus, targeting CD44 is an attractive strategy for detection of atherosclerotic plaques. Herein, we report the synthesis of hyaluronan-conjugated iron oxide nanoworms (HA-NWs). A new purification and gel electrophoresis protocol was developed to ensure the complete removal of free HA from HA-NWs. Compared to the more traditional spherical HA-bearing nanoparticles, HA-NWs had an elongated shape, which interacted much stronger with CD44-expressing cells in CD44- and HA-dependent manners. Furthermore, the HA-NWs did not induce much inflammatory response compared to the spherical HA nanoparticles. When assessed in vivo, HA-NWs enabled successful imaging of atherosclerotic plaques in a clinically relevant model of ApoE knockout transgenic mice for noninvasive plaque detection by MRI. Thus, nanoprobe shape engineering can be a useful strategy to significantly enhance their desired biological properties.

Abstract
BACKGROUND Atherosclerosis and atherosclerosis-related complications are the main cause of death in the world. Vascular injury in response to inflammation and enhanced oxidant stress promotes endothelial dysfunction and leads to atherosclerotic lesions. OBJECTIVES Low-dose treatment with darbepoetin-α may be a potential therapeutic tool for endothelial injury and atherosclerosis. MATERIAL AND METHODS In order to study the effect of darbepoetin-α on endothelial injury and atherosclerosis, we used ApoE-/- mice as the atherosclerotic mice model. We monitored atherosclerosis and plaque formation histochemically in ApoE knockout mice at early and late stages of atherosclerosis. Darbepoetin-α was injected intraperitoneally at a dose of 0.1 μg/kg to ApoE-/- mice. The results of 2 ApoE-/- mice groups injected with darbepoetin-α (early and late stages of atherosclerosis) were compared to the results of the corresponding saline injected ApoE-/- mice groups and the control (C57BL/6) mice. RESULTS Lipid profile (total cholesterol, triglyceride), inflammation (CRP, IL-6, histamine), endothelial injury (ICAM-1, selectin) and oxidative stress markers (lipid peroxidation, protein oxidation) were significantly increased in 4 atherosclerotic groups compared to the control group. Short-term darbepoetin-α had no marked effects on indicators of inflammation and endothelial injury in the ApoE knockout mice groups compared to the ApoE knockout mice not treated with darbepoetin-α, however, darbepoetin-α significantly decreased 8-isoprostane and protein carbonyl content. Long term darbepoetin-α treatment reduced oxidative stress in ApoE-/- mice. CONCLUSIONS This study contributes to understanding and elucidating the biochemical changes occurring during early and late stages of atherosclerosis development regarding lipid profile, inflammation, endothelial injury and oxidative stress markers.

Abstract
BACKGROUND Air pollution is associated with significant adverse health effects including increased cardiovascular morbidity and mortality. However research on the cardiovascular effect of "real-world" exposure to ambient particulate matter (PM) in susceptible animal model is very limited. In this study, we aimed to investigate the association between Beijing ambient particle exposure and the atherosclerosis development in the apolipoprotein E knockout mice (ApoE(-/-) mice). METHODS Two parallel exposure chambers were used for whole body exposure among ApoE knockout mice. One of the chambers was supplied with untreated ambient air (PM group) and the other chamber was treated with ambient air filtered by high-efficiency particulate air (HEPA) filter (FA group). Twenty mice were divided into two groups and exposed to ambient PM (n=10 for PM group) or filtered air (n=10 for FA group) for two months from January 18th to March 18th, 2010. During the exposure, the mass concentrations of PM2.5 and PM10 in the two chambers were continuously monitored. Additionally, a receptor source apportionment model of chemical mass balance using 19 organic tracers was applied to determine the contributions of sources on the PM2.5 in terms of natural gas, diesel vehicle, gasoline vehicle, coal burning, vegetable debris, biomass burning and cooking. At the end of the two-month exposure, biomarkers of oxidative stress, inflammation and lipid metabolism in bronchoalveolar lavage fluid (BAL) and blood samples were determined and the plaque area on the aortic endothelium was quantified. RESULTS In the experiment, the concentrations of PM10 and PM2.5 in PM chamber were 99.45μg/m(3) and 61.0μg/m(3) respectively, while PM2.5 in FA chamber was 17.6μg/m(3). Source apportionment analysis by organic tracers showed that gasoline vehicle (39.9%) and coal burning (24.3%) emission were the two major sources contributing to the mass concentration of PM2.5 in Beijing. Among the ApoE knockout mice, the PM group were significantly higher than the FA group in terms of serum total cholesterol, low-density lipoprotein, tumor necrosis factor-alpha (TNF-alpha) and C-reactive protein as well as TNF-alpha and interleukin-6 in BAL. Also the total antioxidant capacity and oxidized low-density lipoprotein were significantly different between the two groups. In addition, pathological analysis of aortic arch reveals that the plaques area in the PM group increased significantly compared to the FA group. CONCLUSIONS Our results demonstrated that ambient PM exposure could induce considerable oxidative stress and systemic inflammation in ApoE knockout mice and contribute to the progression of atherosclerosis.

Abstract
Atherosclerosis is the major etiology underlying myocardial infarction and stroke, and strategies for preventing atherosclerosis are urgently needed. In the context of atherosclerosis, the deletion of the Nrf2 gene, which encodes a master regulator of the oxidative stress response in mammals, reportedly attenuates atherosclerosis formation. However, the precise mechanisms of protection against atherosclerosis are largely unknown. To further clarify the role of Nrf2 in atherosclerosis in vivo, we performed a time course analysis of atherosclerosis development utilizing an ApoE knockout (KO) mouse model. The results demonstrate that oil red O-stainable lesions were similar in size 5 weeks after the initiation of an HFC (high fat and high cholesterol) diet, but the lesions were markedly attenuated in the Nrf2 and ApoE double KO mice (A0N0 mice) compared with the lesions in the ApoE KO mice (A0N2 mice) at 12 weeks. Consistent with these results, the immunohistochemical analysis revealed that Nrf2 activation is observed in late-stage atherosclerotic plaques but not in earlier lesions. The RT-qPCR analysis of 12-week atherosclerotic plaques revealed that Nrf2 target genes, such as Ho-1 and SLPI, are expressed at significantly lower levels in the A0N0 mice compared with the A0N2 mice, and this change was associated with a decreased expression of macrophage M1-subtype genes Arginase II and inducible NO synthase in the A0N0 mice. Furthermore, the bone marrow (BM) transplantation (BMT) analysis revealed that the Nrf2 activity in the BM-derived cells contributed to lesion formation. Therefore, our study has characterized the positive role of Nrf2 in the BM-derived cells during the development of atherosclerosis, which suggests that Nrf2 may influence the inflammatory reactions in the plaques.
