Mutual effect of homocysteine and uric acid on arterial stiffness and cardiovascular risk in the context of predictive, preventive, and personalized medicine. EPMA J 2022; 13:581-595. [PMID: 36505895 PMCID: PMC9727018 DOI: 10.1007/s13167-022-00298-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Accepted: 08/26/2022] [Indexed: 12/15/2022]
Abstract
Background Arterial stiffness is a major risk factor and effective predictor of cardiovascular diseases and a common pathway of pathological vascular impairments. Homocysteine (Hcy) and uric acid (UA) own the shared metabolic pathways to affect vascular function. Serum uric acid (UA) has a great impact on arterial stiffness and cardiovascular risk, while the mutual effect with Hcy remains unknown yet. This study aimed to evaluate the mutual effect of serum Hcy and UA on arterial stiffness and 10-year cardiovascular risk in the general population. From the perspective of predictive, preventive, and personalized medicine (PPPM/3PM), we assumed that combined assessment of Hcy and UA provides a better tool for targeted prevention and personalized intervention of cardiovascular diseases via suppressing arterial stiffness. Methods This study consisted of 17,697 participants from Beijing Health Management Cohort, who underwent health examination between January 2012 and December 2019. Brachial-ankle pulse wave velocity (baPWV) was used as an index of arterial stiffness. Results Individuals with both high Hcy and UA had the highest baPWV, compared with those with low Hcy and low UA (β: 30.76, 95% CI: 18.36-43.16 in males; β: 53.53, 95% CI: 38.46-68.60 in females). In addition, these individuals owned the highest 10-year cardiovascular risk (OR: 1.49, 95% CI: 1.26-1.76 in males; OR: 7.61, 95% CI: 4.63-12.68 in females). Of note, males with high homocysteine and low uric acid were significantly associated with increased cardiovascular risk (OR: 1.30, 95% CI: 1.15-1.47), but not the high uric acid and low homocysteine group (OR: 1.02, 95% CI: 0.90-1.16). Conclusions This study found the significantly mutual effect of Hcy and UA on arterial stiffness and cardiovascular risk using a large population and suggested the clinical importance of combined evaluation and control of Hcy and UA for promoting cardiovascular health. The adverse effect of homocysteine on arteriosclerosis should be addressed beyond uric acid, especially for males. Monitoring of the level of both Hcy and UA provides a window opportunity for PPPM/3PM in the progression of arterial stiffness and prevention of CVD. Hcy provides a novel predictor beyond UA of cardiovascular health to identify individuals at high risk of arterial stiffness for the primary prevention and early treatment of CVD. In the progressive stage of arterial stiffness, active control of Hcy and UA levels from the aspects of dietary behavior and medication treatment is conducive to alleviating the level of arterial stiffness and reducing the risk of CVD. Further studies are needed to evaluate the clinical effect of Hcy and UA targeted intervention on arterial stiffness and cardiovascular health.

BMC Cardiovasc Disord 2021; 21:484. [PMID: 34627150 PMCID: PMC8501702 DOI: 10.1186/s12872-021-02302-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Accepted: 09/27/2021] [Indexed: 11/25/2022] Open
Abstract
Background The prevalence of coronary artery disease (CAD) continues to increase among young Chinese adults. Current smoking has been recognized as a major risk factor for premature CAD, and hyperhomocysteinaemia (HHcy) has also been suggested to be associated with CAD progression. However, the combined effect of current smoking and HHcy on the severity of coronary artery stenosis in young adults is still uncertain. Methods We consecutively collected young patients (18–35 years of age), diagnosed with CAD and underwent coronary angiography (CAG) at Anzhen Hospital between January 2013 and May 2020. HHcy was defined as serum homocysteine (Hcy) level > 15 µmol/L. The severity of coronary artery stenosis was evaluated by Gensini Score. The co-effect of current smoking and HHcy on CAD severity as well as the relationship between plasma Hcy, pack-years of smoking and CAD severity were assessed by multivariate linear regression analysis. Results A total of 989 participants (mean age, 33 years; 96.2% male) fulfilling the criteria were enrolled in this study. Patients with both HHcy and current smoking accounted for 39.1% of all the subjects. Multivariate liner analysis indicated both serum Hcy levels (β 0.302; 95% CI 0.141–0.462; P < 0.001) and pack-years of smoking (β 0.523; 95% CI 0.265–0.781; P < 0.001) were independently associated with the severity of coronary artery stenosis after adjusting for other traditional confounders. In addition, serum Hcy levels were correlated with pack-years of smoking in young CAD patients (r = 0.116, P = 0.001). Moreover, combination of HHcy and current smoking was suggested to have higher risk for CAD severity (β 17.892; 95% CI 11.314–24.469; P < 0.001), compared with HHcy (β 7.471; 95% CI 0.009–14.934; P = 0.048) or current smoking (β 7.421; 95% CI 0.608–14.233; P = 0.033) alone. Conclusion Combination of HHcy and smoking is independently associated with the severity of CAD in young patients ≤ 35 years of age.

BMC Cardiovasc Disord 2021; 21:47. [PMID: 33485300 PMCID: PMC7825206 DOI: 10.1186/s12872-021-01869-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Accepted: 01/08/2021] [Indexed: 02/08/2023] Open
Abstract
Background The prevalence of acute coronary syndrome (ACS) continues to increase among young Chinese adults. Homocysteine (HCY) has been suggested as a promoter of atherosclerosis leading to coronary artery disease (CAD). Yet, it remains uncertain whether HCY is associated with the ACS and the severity of coronary artery stenosis in young adults. Methods Young patients (18–35 years of age) diagnosed with ACS who underwent coronary angiography (CAG) at Anzhen Hospital between January 2013 and June 2019 were assigned to the ACS group. As confirmed by CAG during the same period, an equivalent age-matched population without CAD was assigned to the non-CAD group. A serum HCY level > 15 µmol/L was defined as hyperhomocysteinemia (HHCY). The Gensini score assessed the severity of coronary artery stenosis. Results A total of 1103 participants, including 828 ACS patients and 275 non-CAD subjects, were enrolled in this study. Young ACS patients had higher level of serum HCY and greater prevalence of HHCY compared with non-CAD subjects [for HCY, 16.55 (11.93–29.68) vs 12.50 (9.71–17.42), P < 0.001; for HHCY prevalence, 62.08% vs 26.18%, P < 0.001]. Multivariate logistic regression analysis with the stepwise method indicated that HHCY was an independent predictor associated with the presence of ACS, after adjusting for traditional confounders (OR, 4.561; 95% CI, 3.288–6.327; P < 0.001). Moreover, young ACS patients with HHCY had increased prevalence of ST-segment elevation myocardial infarction (STEMI) (P = 0.041), multi-vessel disease (P = 0.036), and decreased value of left ventricular ejection fraction (LVEF) (P = 0.01). Also, the HCY level was significantly correlated with Gensini Score in ACS patients (r = 0.142, P < 0.001). Conclusion HHCY is significantly associated with the presence of ACS and the severity of coronary artery stenosis in young adults ≤ 35 years of age.

Abstract
Assesment of arterial stiffness the substantional prognostic factor for evaluating complications of cardiovascular diseases (CVD) in patients with atherosclerosis, hypertension and type 2 diabetes, may be performed using different parameters, including cardio-ankle vascular index (CAVI). The main purpose of this review is to analyze data from studies where CAVI is used to test the arterial wall stiffness in magistral vessels. CAVI measurement is non-invasive and performed by portable devices which makes it comfortable for ambulatory use in patients who come for a check-up and also in those who already are hospitalized. It does not require any special knowledge from investigator and the test lasts a couple of minutes long. CAVI does not depend on blood pressure changes and is more specific in structural changes of arterial wall assessment than brachial-ankle pulse wave velocity (baPWV). CAVI shows considerable correlation with markers of CVD like atherosclerotic plaques in vessels, diastolic disfunction of left ventricle and angina pectoris. CAVI may be used for early monitoring and assessing the lesions of target organs in patients with atherosclerosis, chronic hypertension and type 2 diabetes. Establishing CAVI as a standart parameter in assessing patients who are at risk of CVD can help to improve complications prevention, reduce mortality and prolong their lifespan.

Abstract
Psoriasis is caused by a complex interplay among the immune system, genetic background, autoantigens, and environmental factors. Recent studies have demonstrated that patients with psoriasis have a significantly higher serum homocysteine (Hcy) level and a higher prevalence of hyperhomocysteinaemia (HHcy). Insufficiency of folic acid and vitamin B12 can be a cause of HHcy in psoriasis. Hcy may promote the immuno-inflammatory process in the pathogenesis of psoriasis by activating Th1 and Th17 cells and neutrophils, while suppressing regulatory T cells. Moreover, Hcy can drive the immuno-inflammatory process by enhancing the production of the pro-inflammatory cytokines in related to psoriasis. Hcy can induce nuclear factor kappa B activation, which is critical in the immunopathogenesis of psoriasis. There may be a link between the oxidative stress state in psoriasis and the effect of HHcy. Hydrogen sulfide (H2S) may play a protective role in the pathogenesis of psoriasis and the deficiency of H2S in psoriasis may be caused by HHcy. As the role of Hcy in the pathogenesis of psoriasis is most likely established, Hcy can be a potential therapeutic target for the treatment of psoriasis. Systemic folinate calcium, a folic acid derivative, and topical vitamin B12 have found to be effective in treating psoriasis.

Abstract
Introduction: This study aimed to examine the association of smoking status with homocysteine levels and to determine whether the association is modified by oestradiol or cholesterol.Methods: Data (N = 4580) were obtained from National Health and Nutrition Examination Survey 2003-2004 with analysis done in 2018 on adults aged ≥20 years. The outcome was homocysteine; smoking status was the exposure variable and categorized as current, former or never smoker. Generalized linear models were used to examine the associations between smoking status and homocysteine levels, while assessing the impact of oestradiol and cholesterol.Results: After adjusting for age, sex, ethnicity, education and income level, homocysteine levels did differ by smoking status ((current smokers versus never smokers: β: 0.18 CI: 0.00, 0.36), (former smokers: β: 0.10 CI: -0.09, 0.28)). The addition of oestradiol as an interaction term in adjusted models was associated with a 16.6% increase in homocysteine levels when compared to models without the interaction term. Oestradiol but not cholesterol did moderate the association between smoking status and homocysteine levels.Discussion and conclusions: Homocysteine levels did differ across smoking status after adjusting for confounders. Oestradiol did moderate the relationship between homocysteine and smoking status.

Abstract
Hypertension and hyperhomocystinemia have a joint effect on the risk of stroke. We aimed to evaluate the relationship between plasma total homocysteine (tHcy) and blood pressure in two independent Chinese populations. Four thousand five hundred and fifty-five participants who underwent health examinations between March 2016 and September 2016 at Peking University First Hospital were enrolled as 'Population 1', and 2689 participants who were admitted to Peking University First Hospital between January 2014 and December 2015 were enrolled as 'Population 2'. None of the study participants were taking antihypertensive medication or vitamins, or had cardio-cerebrovascular disease or chronic kidney disease stages 4 or 5. In Population 1, a 5 μmol/L increase in tHcy was associated with a 0.47 mmHg (95% confidence interval [CI]: 0.23-0.70 mmHg, p < 0.01) increase in systolic blood pressure (SBP) and a 0.14 mmHg (95% CI: -0.02 to 0.30 mmHg, p = 0.08) increase in diastolic blood pressure (DBP). In Population 2, a 5 μmol/L increase in tHcy was associated with a 0.42 mmHg (95% CI: 0.13-0.72 mmHg, p < 0.01) increase in SBP and a 0.29 mmHg (95% CI: 0.09-0.49 mmHg, p < 0.01) increase in DBP. The prevalence of hypertension was significantly higher in Population 1 (by 47%; odds ratio [OR] 1.47, 95% CI: 1.09-1.98, p = 0.01) and in Population 2 (by 55%;OR 1.55, 95% CI: 1.15-2.08, p < 0.01) in participants with tHcy ≥ 15 μmol/l than in those with tHcy < 10 μmol/L. Stratified analysis showed that the association was stronger in women than in men.

Abstract
Homocysteine (Hcy) increases oxidation and inflammation; however, the mechanism of Hcy-induced bone fragility remains unclear. Because selective estrogen modulators (SERMs) have an anti-oxidative effect, SERMs may rescue the Hcy-induced bone fragility. We aimed to examine whether oxidative stress and pro-inflammatory cytokines such as interleukin (IL)-1β and IL-6 are involved in the Hcy-induced apoptosis of osteocytes and whether bazedoxifene (BZA) inhibits the detrimental effects of Hcy. We used mouse osteocyte-like cell lines MLO-Y4-A2 and Ocy454. Apoptosis was examined by DNA fragmentation ELISA and TUNEL staining, and gene expression was evaluated by real-time PCR. Hcy 5 mM significantly increased expressions of NADPH oxidase (Nox)1, Nox2, IL-1β, and IL-6 as well as apoptosis in MLO-Y4-A2 cells. Nox inhibitors, diphenyleneiodonium chloride and apocynin, significantly suppressed Hcy-induced IL-1β and IL-6 expressions. In contrast, an IL-1β receptor antagonist and an IL-6 receptor monoclonal antibody had no effects on Hcy-induced Nox1 and Nox2 expressions, but significantly rescued Hcy-induced apoptosis. BZA (1 nM-1 μM) and 17β estradiol 100 nM significantly rescued Hcy-induced apoptosis, while an estrogen receptor blocker ICI 182,780 reversed the effects of BZA and 17β estradiol. BZA also rescued Hcy-induced apoptosis of Ocy454 cell, and ICI canceled the effect of BZD. Moreover, BZA significantly ameliorated Hcy-induced expressions of Nox1, Nox2, IL-1β, and IL-6, and ICI canceled the effects of BZA on their expressions. Hcy increases apoptosis through stimulating Nox 1 and Nox 2-IL-1β and IL-6 expressions in osteocyte-like cells. BZA inhibits the detrimental effects of Hcy on osteocytes via estrogen receptor.

Both increased arterial stiffness and higher total homocysteine (tHcy) are associated with an elevated risk for cardiovascular disease. However, the relationship between tHcy and arterial stiffness is still inconclusive. The authors aimed to test the relationship of tHcy with carotid-femoral pulse wave velocity (cfPWV) and examine the possible effect modifiers in adults. A study was conducted from July to September 2016 in Jiangsu Province, China. A total of 16 644 participants were enrolled in the final analysis. Increased arterial stiffness is defined as a cfPWV ≥10 m/s. Overall, there was a positive association between tHcy and cfPWV levels (per 5-μmol/L tHcy increase: β = 0.10; 95% confidence interval [CI], 0.08-0.13) and increased arterial stiffness (per 5-μmol/L tHcy increase: odds ratio, 1.11; 95% CI, 1.07-1.14). Compared with participants with tHcy <10 μmol/L, the significantly higher cfPWV levels were observed in those with tHcy ≥15 μmol/L (β = 0.37; 95% CI, 0.28-0.47). Accordingly, a higher prevalence of increased arterial stiffness was found in patients with tHcy10 to <15 μmol/L (odds ratio, 1.18; 95% CI, 1.05-1.33) and tHcy ≥15 μmol/L (odds ratio, 1.50; 95% CI, 1.32-1.71) as compared with participants with tHcy <10 μmol/L. Furthermore, the stronger positive association was found in participants who were older (≥60 years, P for interaction = .008), had low body mass index (<25 kg/m2 , P for interaction = .026), high systolic blood pressure levels (≥145 mm Hg [median], P for interaction = .048), or diabetes mellitus (P for interaction = .045). The present study demonstrated that serum tHcy concentrations were positively associated with cfPWV and the prevalence of increased arterial stiffness. These results suggest that the cardiovascular effects of tHcy may partly be mediated through arterial stiffness.

Abstract
The results of multi-center trials of B vitamin supplementation reveal that, whereas moderately elevated homocysteine predicts increased risk for coronary disease, it does not play a mediating role in this regard. This essay proposes that interleukin-1beta can act on hepatocytes to suppress expression of the hepatocyte-specific forms of methionine adenosyltransferase; this in turn can be expected to decrease hepatic activity of cystathionine-β-synthase, leading to an increase in plasma homocysteine. It is further proposed that interleukin-1beta (IL-1β) is a true mediating risk factor for cardiovascular disease, and that elevated homocysteine predicts coronary disease because it can serve as a marker for increased IL-1β activity. Potent statin therapy may decrease IL-1β production by suppressing inflammasome activation - thereby accounting for the marked protection from cardiovascular events observed in the classic JUPITER study, in which the enrolled subjects had low-normal Low Density Lipoprotein cholesterol but elevated C-reactive protein.

Abstract
OBJECTIVE Hypothyroidism (HO) can induce metabolic dysfunctions related to insulin resistance and dyslipidemia. Our previous studies showed that homocysteine (Hcy) impaired the coronary endothelial function and that Hcy can promote chemokine expression and insulin resistance (IR) by inducing endoplasmic reticulum stress in human adipose tissue and hypothyroid patients. The aim of this study was to investigate the potential harmful correlation between plasma Hcy and low-density lipoprotein cholesterol (LDL-C) in patients with HO. METHODS A total of 286 subjects were enrolled. All subjects were divided into the following 3 groups: HO group, subclinical hypothyroidism (SHO) group, and control group. Statistical analyses were carried out to evaluate the correlation between the plasma levels of Hcy and LDL-C in HO patients. The changes in the plasma Hcy levels and other metabolic parameters were measured before and after levothyroxine (L-T4) treatment. The relationship between the changes in the plasma Hcy level and the LDL-C level was also evaluated after L-T4 treatment. RESULTS In the patients with HO, both the plasma Hcy and LDL-C levels were significantly higher than those of the controls. The plasma levels of Hcy were positively correlated with the LDL-C level in the HO group. L-T4 treatment resulted in a significant decrease in the BMI, total cholesterol (TC), LDL-C, triglycerides (TG), apolipoprotein B (ApoB), and Hcy levels. Moreover, the decrease in Hcy (ΔHcy) was positively correlated with decreased LDL-C (ΔLDL-C) levels after L-T4 treatment in HO patients. CONCLUSION Our results suggest that the increased Hcy level was positively correlated with the LDL-C in the HO group. A potential harmful interaction may exist between Hcy and LDL-C under the HO condition. In addition to reducing the plasma levels of Hcy, L-T4 treatment exerts beneficial effects on patients with HO by improving dyslipidemia, including a decrease in the LDL-C level.

Abstract
Vegetarian diets have been associated with a lower incidence of several chronic diseases. The benefits of plant-based diets are related mainly to the improvement of metabolic parameters that can indicate risk for such diseases. Some metabolic factors, such as oxidative balance, lipid profile, and glucose homeostasis, can be improved directly by diet, but paradoxically, some characteristics of vegetarian diets may promote a negative scenario that increases the risk of certain chronic diseases. Additionally, many benefits of a vegetarian diet are mediated by the gut microbiota, members of which not only have taxonomic and functional differences but also produce diverse, specific metabolites that vary according to whether the host consumes an omnivorous or a vegetarian diet. This review examines the modulation of human metabolism and gut microbiota by vegetarian and omnivorous dietary patterns and explores how this modulation may affect the risk of cardiovascular disease.

Abstract
AIM Observational studies have reported that elevated homocysteine (Hcy) levels are associated with the risk of cardiovascular disease (CVD). However, interventions that lower Hcy do not provide a corresponding risk reduction. Therefore, the causal role of Hcy in CVD remains unclear. This 5-year prospective study investigated the associations of Hcy levels, folate intake, and host factors with arterial stiffness among the general Japanese population. METHODS We prospectively recruited 658 participants (40-69 years old) from the general population during regular health checkup examinations. Arterial stiffness was evaluated using the cardio-ankle vascular index (CAVI) at baseline and the 5-year follow-up. Folate intake was estimated using a structured questionnaire. Genotyping was used to evaluate the MTHFR C677T and MS A2756G gene polymorphisms. Ultrafast liquid chromatography was used to measure total plasma Hcy levels. Association between these variables and CAVI values was evaluated using general linear regression and logistic regression models that were adjusted for atherosclerosis-related factors. RESULTS Men had higher Hcy levels and CAVI values and lower folate intake than women (all, p<0.001). At baseline, Hcy, folate intake, and the two genotypes were not associated with CAVI values for both sexes. Among men, Hcy levels were positively associated with CAVI values at the 5-year follow-up (p=0.033). Folate intake and the two genotypes were not associated with the 5-year CAVI values. CONCLUSION Plasma Hcy may be involved in arterial stiffness progression, as monitored using CAVI, among men.

Abstract
The authors investigated whether plasma total homocysteine (tHcy) is a predictive factor for arterial stiffness (carotid-femoral pulse wave velocity [cf-PWV] and carotid-radial PWV) in 1447 patients from a 4.8-year prospective study in Beijing, People's Republic of China. Baseline tHcy showed a significant relationship with follow-up cf-PWV (β=0.817, P=.015) in a multivariable linear regression analysis. A stepwise logistic regression model showed that baseline levels of tHcy were significantly associated with follow-up cf-PWV in the adjusted models. Furthermore, the baseline tHcy levels showed a significant association with increases in cf-PWV. There was no association between the change in tHcy and increase in PWV. The present study clearly demonstrated an association between tHcy levels and arterial stiffness, indicating that tHcy is an independent predictive factor for arterial stiffness in a community-based population.

Abstract
Background Arterial stiffness and homocysteine are both powerful predictors of cardiovascular disease, especially in older populations. Previous studies have investigated the association of homocysteine with arterial stiffness in human subjects, while the relationship between homocysteine and arterial stiffness in the elderly is still indefinite. The current study examined the association of homocysteine with arterial stiffness in Chinese community-based elderly persons. Methods We related serum levels of homocysteine to two measures of arterial stiffness (carotid-femoral pulse wave velocity (PWV) and carotid-radial PWV) in 780 participants (46.3% men, mean age 71.9 years (ranging 65–96 years old)) from two communities of Beijing, China. Arterial stiffness was measured within two days of the time of biomarker measurement. Results In multiple-adjusted models, homocysteine levels were strongly associated with the carotid-femoral PWV (standardized β = 0.13, P < 0.001), even after adjustment for classical risk factors of cardiovascular disease. The association is also stronger when the carotid-femoral PWV is elevated above normal, whereas no significant association with homocysteine was observed for carotid-radial PWV. Conclusions In Chinese elderly persons, serum homocysteine levels are associated with alterations of aortic stiffness.

Abstract
BACKGROUND Increased oxidative stress contributes to the development of arterial stiffness. Arterial stiffness, as measured by brachial-ankle pulse wave velocity (baPWV), has been known to be correlated with oxidative stress. Serum ceruloplasmin (CP), a copper-carrying protein, may indicate the overall level of oxidative stress in the body. The present study investigated whether serum CP levels are associated with baPWV in Korean men with type 2 diabetes mellitus (DM). SUBJECTS AND METHODS Serum CP levels and conventional risk factors were measured in 760 Korean men with type 2 DM. Arterial stiffness was assessed by baPWV obtained with an automatic device (model VP-1000; Colin, Komaki, Japan). RESULTS Correlation analysis indicated a significant positive association between serum CP and baPWV (r = 0.109, P = 0.003). Age-adjusted baPWV increased gradually according to serum CP quartiles (Q1, 1,500.3 ± 18.4 cm/s; Q2, 1,511.6 ± 17.8 cm/s; Q3, 1,551.8 ± 17.9 cm/s; Q4, 1,622.1 ± 17.8 cm/s; P for trend < 0.001). Multivariate linear regression analysis showed that serum CP was independently associated with baPWV in various models. CONCLUSIONS A positive relationship was identified between CP and baPWV in adult male subjects with type 2 DM, which was independent of conventional cardiovascular risk factors. Further studies are needed to confirm whether CP contributes to the pathogenesis of increased arterial stiffness in subjects with type 2 DM.

Abstract
The anti-inflammatory, antioxidative, and antiarteriosclerosis activities of simvastatin along with its protective effects on the endothelium suggest that it may also have antiaging effects. The aim of this study was to investigate the antiaging effects of simvastatin as well as its effects on sirtuin 1 (SIRT1) expression in endothelial cells. Aged rats and human umbilical vein endothelial cells were treated with simvastatin in the presence and absence of oxidized low-density lipoprotein (OX-LDL). Aortic β-galactosidase staining was undertaken to determine senescence, and SIRT1 protein expression was evaluated using Western blot analysis. After simvastatin therapy, arterial endothelial cell aging was significantly reduced, and SIRT1 expression was significantly increased. The OX-LDL significantly accelerated the senescence of umbilical vein endothelial cells and decreased SIRT1 expression. The OX-LDL-induced downregulation of SIRT1 was blocked by simvastatin. Simvastatin treatment also reduced umbilical vein endothelial cell aging and increased SIRT1 expression.
