Abstract
Aging is currently viewed as a result of multiple biological processes that manifest themselves independently, reinforce each other and in their totality lead to the aged phenotype. Genetic and pharmaceutical approaches targeting specific underlying causes of aging have been used to extend the lifespan and healthspan of model organisms ranging from yeast to mammals. However, most interventions display only a modest benefit. This outcome is to be expected if we consider that even if one aging process is successfully treated, other aging pathways may remain intact. Hence solving the problem of aging may require targeting not one but many of its underlying causes at once. Here we review the challenges and successes of combination therapies aimed at increasing the lifespan of mammals and propose novel directions for their development. We conclude that both additive and synergistic effects on mammalian lifespan can be achieved by combining interventions that target the same or different hallmarks of aging. However, the number of studies in which multiple hallmarks were targeted simultaneously is surprisingly limited. We argue that this approach is as promising as it is understudied.

Abstract
AIMS Chronic kidney disease (CKD) is widely prevalent and independently increases cardiovascular risk. Cardiovascular risk prediction tools derived in the general population perform poorly in CKD. Through large-scale proteomics discovery, this study aimed to create more accurate cardiovascular risk models. METHODS AND RESULTS Elastic net regression was used to derive a proteomic risk model for incident cardiovascular risk in 2182 participants from the Chronic Renal Insufficiency Cohort. The model was then validated in 485 participants from the Atherosclerosis Risk in Communities cohort. All participants had CKD and no history of cardiovascular disease at study baseline when ∼5000 proteins were measured. The proteomic risk model, which consisted of 32 proteins, was superior to both the 2013 ACC/AHA Pooled Cohort Equation and a modified Pooled Cohort Equation that included estimated glomerular filtrate rate. The Chronic Renal Insufficiency Cohort internal validation set demonstrated annualized receiver operating characteristic area under the curve values from 1 to 10 years ranging between 0.84 and 0.89 for the protein and 0.70 and 0.73 for the clinical models. Similar findings were observed in the Atherosclerosis Risk in Communities validation cohort. For nearly half of the individual proteins independently associated with cardiovascular risk, Mendelian randomization suggested a causal link to cardiovascular events or risk factors. Pathway analyses revealed enrichment of proteins involved in immunologic function, vascular and neuronal development, and hepatic fibrosis. CONCLUSION In two sizeable populations with CKD, a proteomic risk model for incident cardiovascular disease surpassed clinical risk models recommended in clinical practice, even after including estimated glomerular filtration rate. New biological insights may prioritize the development of therapeutic strategies for cardiovascular risk reduction in the CKD population.

Abstract
Bellidifolin (BEL), a xanthone compound, has significant therapeutic effectiveness in cardiac diseases such as arrhythmias. However, BEL is limited in clinical applications by its hydrophobicity. In this work, we used BEL as the active pharmaceutical ingredient (API), and polyethylene glycol 15-hydroxy stearate (Kolliphor HS15) as the carrier to prepare BEL nano-micelles by a solvent-volatilization method. According to an analysis by differential scanning calorimetry (DSC), BEL was successfully encapsulated in HS15 as BEL nano-micelles with a 90% encapsulation rate, and particle size was 12.60 ± 0.074 nm in the shape of a sphere and electric potential was −4.76 ± 4.47 mV with good stability and sustained release characteristics. In addition, compared with free drugs, these nano-micelles can increase cellular uptake capacity, inhibit the proliferation of human cardiac fibroblasts, and down-regulate the expression of Smad-2, α-SMA, Collagen I, and Collagen III proteins in myocardial cells to improve myocardial fibrosis. In conclusion, the BEL nano-micelles can provide a new way for the theoretical basis for the clinical application of anti-cardiac fibrosis. Bellidifolin (BEL), a xanthone compound, has significant therapeutic effectiveness in cardiac diseases such as arrhythmias.![]()

Abstract
The effects of environmental chemicals on health outcomes may be underestimated due to deficiency of knowledge regarding the actions of compounds on toxico-pathogenic mechanisms underlying biological systems outcomes. In this regard, the current study aimed to explore the potential target-pathway-disease relationship attributed to bisphenol A (BPA) responses in target tissues. Computational methods including reverse pharmacophore mapping approach, structural similarity based search and kinome wide interaction profiling were employed with molecular docking validation. Gene ontology (GO) enrichment analysis and protein-protein interaction (PPI) network based illustrations were utilized to prioritize target-pathway and disease relationships. Data illustrated that BPA possessed multi-target nature since this chemical potentially interacted with various protein targets where many of these were validated through docking. Potential BPA targets were significantly enriched to various cellular signaling pathways including steroid biosynthesis, peroxisome proliferator-activated receptor gamma (PPARℽ) and cancer. Further, hypertension was prioritized as disease target. In addition, BPA targeted 17 cell signaling kinases encompassed in the human kinome. In addition, inflammatory (5-LO) and apoptosis regulators (Bcl-X and Bcl-2) were also explored as novel targets. Evidence indicates that the multi-target nature and plausible mechanisms underlying BPA actions in a system wide manner aids toward understanding of adverse effects. This observation may lead us to more precise method to elucidate the toxico-pathogenic mechanisms of BPA with an environmental health perspective.

[PMID: 34389253 DOI: 10.1016/j.hlc.2021.06.524] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Revised: 05/26/2021] [Accepted: 06/02/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Lack of blood pressure control leads to a higher incidence of hypertension-mediated target organ damage (HMOD). One of the markers of HMOD is an increased arterial stiffness, an independent predictor of cardiovascular complications. However, abstract numbers showing the level of arterial stiffness do not give patients a clear understanding of the risk of their condition. In order to increase patient compliance, the term "vascular age" (VA) was introduced. Arteriosclerosis plays the main role in increasing VA. The greatest interest, according to the literature, in the study of this issue is in arteriosclerosis caused by transforming growth factor β1 (TGF-β1)-the effect of TGF-β1 on the culture of smooth muscle cells leads to their proliferation and growth; also, TGF-β1 increases the amount of collagen and accelerates the degradation of elastin. METHODS We included 140 people in the study: 80 patients with controlled arterial hypertension (CAH), 30 with uncontrolled arterial hypertension (UAH), and 30 patients who formed the control group. All patients underwent a determination of arterial stiffness and VA using the cardio-ankle vascular index (CAVI), a corrected (blood-pressure independent) cardio-ankle vascular index (CAVI0) and the concentration of TGF-β1 was measured. RESULTS The TGF-β1 value in the UAH group was 22.6 (25th percentile=20.6; 75th percentile=25.6) ng/mL, and in the control group it was 17.4 (25th percentile=11.8; 75th percentile=19.3) ng/mL. In the CAH group, an intermediate value was noted-19.2 (25th percentile=17.2; 75th percentile=24.7) ng/mL. The CAVI in the UAH group was 9.2 (25th percentile=8.5; 75th percentile=9.9), in the control group-7 (25th percentile=6.5; 75th percentile=7.5). In the CAH group, the average CAVI was 7.8 (25th percentile=7.0; 75th percentile=8.5). The CAVI 0 in the UAH group was 14.8 (25th percentile=12.0; 75th percentile=15.6), in the control group - 9.7 (25th percentile=8.8; 75th percentile=9.7). In the CAH group, the average CAVI was 11.1 (25th percentile=10.1; 75th percentile=13.6). Vascular age in the UAH group was 71.5 (25th percentile=64; 75th percentile=74) years, in the CAH group 59 (25th percentile=49; 75th percentile=69) years, and in both groups (UAH, CAH), VA was significantly higher than the chronological age (p<0.05). In the control group, the VA did not significantly differ from the chronological age (p>0.05) and it was 54 (25th percentile=44; 75th percentile=59) years. A significant relationship was found between the TGF-β1 level and CAVI (CAH r=0.777; UAH r=0.753; p<0.05), CAVI 0 (CAH r=0.625; UAH r=0.502; p<0.05) and VA in patients with AH (CAH r=0.649; UAH r=0.753; p<0.05). CONCLUSION In patients in the UAH group, there was an increase in the concentration of TGF-β1, an increase in the arterial stiffness and in VA in comparison with patients in the CAH group and the control group. The relationship between TGF-β1 and the arterial stiffness and VA was revealed in patients with hypertension.

Abstract
Pancreatic cancer is a common malignant digestive disease. Epidemiological and clinical studies have demonstrated that pancreatic cancer is closely related to diabetes mellitus. Diabetic patients are more likely to develop pancreatic cancer, which is linked with poor outcomes. Pancreatic cancer is complicated with abnormal blood sugar and insulin resistance and promotes the development of diabetes mellitus. Understanding the molecular mechanisms linking diabetes mellitus and pancreatic cancer is essential for the treatment of diabetes cancer patients. The transforming growth factor-β (TGF-β) signaling pathway is deregulated in cancer and has a dual role in different stages of cancer as a suppressor or a promoter. More important, The TGF-β signaling pathway is also another important reason for diabetic complications. This review summarizes the relationship between diabetes and pancreatic cancer, in particular, focusing on the role of the TGF-β signaling pathway. It is possible to find drugs like metformin that can prevent and treat pancreatic cancer by targeting the TGF-β signaling pathway.

Abstract
Human and animal longevity is directly bound to their health span. While previous studies have provided evidence supporting this connection, therapeutic implementation of this knowledge has been limited. Traditionally, diseases are researched and treated individually, which ignores the interconnectedness of age-related conditions, necessitates multiple treatments with unrelated substances, and increases the accumulative risk of side effects. In this study, we address and overcome this deadlock by creating adeno-associated virus (AAV)-based antiaging gene therapies for simultaneous treatment of several age-related diseases. We demonstrate the modular and extensible nature of combination gene therapy by testing therapeutic AAV cocktails that confront multiple diseases in a single treatment. We observed that 1 treatment comprising 2 AAV gene therapies was efficacious against all 4 diseases. Comorbidity is common as age increases, and currently prescribed treatments often ignore the interconnectedness of the involved age-related diseases. The presence of any one such disease usually increases the risk of having others, and new approaches will be more effective at increasing an individual’s health span by taking this systems-level view into account. In this study, we developed gene therapies based on 3 longevity associated genes (fibroblast growth factor 21 [FGF21], αKlotho, soluble form of mouse transforming growth factor-β receptor 2 [sTGFβR2]) delivered using adeno-associated viruses and explored their ability to mitigate 4 age-related diseases: obesity, type II diabetes, heart failure, and renal failure. Individually and combinatorially, we applied these therapies to disease-specific mouse models and found that this set of diverse pathologies could be effectively treated and in some cases, even reversed with a single dose. We observed a 58% increase in heart function in ascending aortic constriction ensuing heart failure, a 38% reduction in α-smooth muscle actin (αSMA) expression, and a 75% reduction in renal medullary atrophy in mice subjected to unilateral ureteral obstruction and a complete reversal of obesity and diabetes phenotypes in mice fed a constant high-fat diet. Crucially, we discovered that a single formulation combining 2 separate therapies into 1 was able to treat all 4 diseases. These results emphasize the promise of gene therapy for treating diverse age-related ailments and demonstrate the potential of combination gene therapy that may improve health span and longevity by addressing multiple diseases at once.

Abstract
Objective To demonstrate the underlying mechanisms of aortic dissection compared to
those of coronary artery disease in terms of the transforming growth
factor-beta (TGF-β) signaling pathway. Methods Twenty consecutive aortic dissection patients and 20 consecutive coronary
artery disease patients undergoing a surgical treatment in this hospital
were enrolled into this study. The aortic tissues were sampled and the
TGF-β1 and its receptor TGF-β receptor I
(TβRI) were detected by Western blotting assay. Results TGF-β1 and TβRI were positively expressed in the
aortic tissues in both groups by Western blotting assay. The expressions of
the two proteins were significantly higher in the aortic tissue of patients
with aortic dissection than in those with coronary artery disease. The
quantitative analyses of the relative gray scales of the proteins disclosed
close correlations between the expressions of TGF-β1 and TβRI
in both the study and control group patients. Conclusions The aortic remodeling of aortic dissection might differ from that of coronary
artery atherosclerosis concerning the nature, mechanism, mode, and
activities of TGF-β signaling pathway. The development of aortic
dissection could be associated with a significantly enhanced function of
TGF-β1/Smad signaling transduction as a result of
aortic remodeling incorporating both vascular injury and repair.

Elevated circulating TGF-β is not the cause of increased atherosclerosis development in biglycan deficient mice. Atherosclerosis 2017; 268:68-75. [PMID: 29182988 DOI: 10.1016/j.atherosclerosis.2017.11.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2017] [Revised: 10/14/2017] [Accepted: 11/09/2017] [Indexed: 11/20/2022]
Abstract
BACKGROUND AND AIMS Vascular biglycan contributes to atherosclerosis development and increased biglycan expression correlates with increased atherosclerosis. However, mice deficient in biglycan have either no reduction in atherosclerosis or an unexpected increase in atherosclerosis. Biglycan deficient mice have systemically elevated TGF-β, likely due to lack of sequestration of TGF-β in the extracellular matrix. The purpose of this study was to determine if prevention of TGF-β elevations in biglycan deficient mice affected atherosclerosis development. METHODS Biglycan deficient mice were crossed to Ldlr deficient mice. Diabetes was induced via streptozotocin and all mice were fed a high cholesterol diet. Diabetic biglycan wild type and biglycan deficient Ldlr deficient mice were injected with the TGF-β neutralizing antibody 1D11 or the irrelevant control antibody 13C4. RESULTS Biglycan deficient mice had significantly elevated plasma TGF-β levels, which was further increased by diabetes, and significantly increased atherosclerosis. There was a significant correlation between TGF-β concentrations and atherosclerosis. However, despite nearly complete suppression of plasma TGF-β levels in mice treated with the TGF-β neutralizing antibody 1D11, there was no significant difference in atherosclerosis between mice with elevated TGF-β levels and mice with suppressed TGF-β levels. CONCLUSIONS The increased atherosclerosis in biglycan deficient mice does not appear to be due to elevations in TGF-β.

Abstract
Recent evidence suggests that adventitial fibroblasts (AFs) are crucially implicated in atherosclerosis. However, the mechanisms by which AFs are dysfunctional and contribute to atherosclerosis remain unclear. This study aimed to investigate the role of regulator of G-protein signalling 3 (RGS3) in the regulation of AFs using apoE knockout mouse as the model. Pathological changes in aortic arteries of apoE knockout mice fed with hyperlipid diet were examined by Movat staining. The expression of RGS3, α-SMA, TGF-β1, Smad2, and Smad3 in the adventitia was detected by immunohistochemistry. Adventitial fibroblasts were isolated from aortic arteries of apoE knockout mice and infected with RGS3 overexpression lentivirus or empty lentivirus. The expression of RGS3, α-SMA, TGF-β1, Smad2, and Smad3 in AFs was detected by real-time polymerase chain reaction and Western blot analysis. We found that hyperlipidic diet caused significant aortic intima thickening and atherosclerotic plaques in 15-week-old apoE knockout mice. Compared to wild-type mice, RGS3 expression was lower while α-SMA, TGF-β1, Smad2, and Smad3 expression was higher in the adventitia of apoE knockout mice. In addition, lentivirus mediated overexpression of RGS3 caused decreased expression of α-SMA, TGF-β1, Smad2, and Smad3 in AFs derived from apoE(-/-) mice. In conclusion, these results suggest that RGS3 may provide protection against pathological changes of AFs and the development of atherosclerosis by inhibiting TGF-β1/Smad signalling. RGS3 may be a potential therapeutic target for atherosclerosis.

The Relationship between VEGFA and TGFB1 Polymorphisms and Target Lesion Revascularization after Elective Percutaneous Coronary Intervention. DISEASE MARKERS 2017; 2017:8165219. [PMID: 28811677 PMCID: PMC5546133 DOI: 10.1155/2017/8165219] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/23/2017] [Revised: 06/10/2017] [Accepted: 06/14/2017] [Indexed: 12/31/2022]
Abstract
Background and Aim The specific association between genetic variation and in-stent restenosis is still only partly understood. The aim of this study is to analyze the relationship between functional polymorphisms in the genes encoding vascular endothelial growth factor A (VEGF-A; rs699947) and transforming growth factor beta 1 (TGF-β1; rs1800470) and target lesion revascularization (TLR) risk. Methods A total of 676 patients (805 lesions) with stable coronary artery disease (SCAD) who received elective percutaneous coronary intervention (PCI) with at least one bare-metal stent implantation were included. The primary study endpoint was TLR at a 4-year follow-up. Results The TLR rate was higher in patients with the VEGFA A/A genotype (15.4%) than in patients with the VEGFA A/C (7.9%) and C/C (8.9%) genotypes (p = 0.009). The VEGFA A/A genotype, after adjustment for clinical and procedural covariates, remained significantly and independently associated with the TLR (hazard ratio—2.09 [95% confidence interval 1.32–3.33, p = 0.0017]). However, we found no association between TLR and the TGFB1 genotype. Conclusion The VEGFA A/A genotype is significantly and independently associated with TLR risk in Polish SCAD patients who received elective PCI with bare-metal stent implantation.

Abstract
Smad4, a key transcription factor in the transforming growth factor-β signaling pathway, is involved in a variety of cell physiologic and pathologic processes. Here, we characterized megakaryocyte/platelet-specific Smad4 deficiency in mice to elucidate its effect on platelet function. We found that megakaryocyte/platelet-specific loss of Smad4 caused mild thrombocytopenia and significantly extended first occlusion time and tail bleeding time in mice. Smad4-deficient platelets showed reduced agonist-induced platelet aggregation. Further studies showed that a severe defect was seen in integrin αIIbβ3-mediated bidirectional (inside-out and outside-in) signaling in Smad4-deficient platelets, as evidenced by reduced fibrinogen binding and α-granule secretion, suppressed platelet spreading and clot retraction. Microarray analysis showed that the expression levels of multiple genes were altered in Smad4-deficient platelets. Among these genes, spleen tyrosine kinase (Syk) and Rho-associated coiled-coil containing protein kinase 2 (ROCK2) were downregulated several times as confirmed by quantitative reverse-transcription polymerase chain reaction and immunoblotting. Further research showed that Smad4 directly regulates ROCK2 transcription but indirectly regulates Syk. Megakaryocyte/platelet-specific Smad4 deficiency caused decreased expression levels of Syk and ROCK2 in platelets. These results suggest potential links among Smad4 deficiency, attenuated Syk, and ROCK2 expression and defective platelet activation.

Abstract
BACKGROUND Prognosis in chronic kidney disease (CKD) for adverse outcomes differs substantially based on the etiology of CKD. We examined whether the biomarker profile differed based on CKD etiology and whether they were associated with mortality. METHODS Prospective observational study of 1,157 patients, 663 with diabetic kidney disease (DKD), 273 with glomerulonephritis (GN), and 221 with cystic/interstitial disease (polycystic kidney disease, pyelonephritis or chronic tubulointerstitial nephritis [PCK/TIN]) were identified in the Canadian Study of Prediction of Dialysis, Death and Interim Cardiovascular events over Time cohort. The outcome of interest was mortality before commencing dialysis. The biomarker profile consisted of N-terminal pro-brain natriuretic peptide (NT-proBNP), troponin I (TnI), asymmetric dimethylarginine (ADMA), interleukin (IL)-6, high sensitivity C-reactive protein, fibroblast growth factor-23 (FGF23), transforming growth factor-beta, 25-hydroxylvitamin D, and cystatin C (CysC). RESULTS The mean estimated glomerular filtration rate was 27 mL/min/1.73 m2 and median follow-up time was 44 months. Mortality before dialysis commencement was the greatest in DKD (20%), followed by PCK/TIN (13%), and was least in those GN (8%). The majority of deaths were cardiovascular in nature, 17, 9, and 5.5% for DKD, PCK/TIN, GN, respectively. Those with DKD had higher hazard for mortality, unadjusted (hazard ratio [HR] 2.7, 95% CI 1.7-4.3) and adjusted (HR 1.7, 95% CI 1.1-2.8). The biomarker profiles associated with mortality differed significantly by CKD etiology as follows: DKD was associated with CysC (HR 1.3, 95% CI 1.0-1.6), ADMA (HR 1.3, 95% CI 1.1-1.6), and NT-proBNP (HR 1.7, 95% CI 1.4-2.1), GN was associated with FGF23 (HR 1.8, 95% CI 1.1-2.8), TnI (HR 3.6, 95% CI 1.3-9.5), and transforming growth factor-beta (HR 0.6, 95% CI 0.4-0.9) and PCK/TIN was associated with ADMA (HR 1.5, 95% CI 1.3-1.8) and IL-6 (HR 2.1, 95% CI 1.5-3.1). CONCLUSIONS Biomarkers profiles differ according to the etiology of CKD and are associated with mortality.

Abstract
Introduction Numerous studies have demonstrated that plasma transforming growth factor-β1 (TGF-β1) may be involved in the pathogenesis of atrial fibrillation (AF), but some discrepancy remained. We performed a meta-analysis to evaluate the association between the plasma level of TGF-β1 and the risk of AF. Methods Published clinical studies evaluating the association between the plasma level of TGF-β1 and the risk of AF were retrieved from PubMed and EMBASE databases. Two reviewers independently evaluated the quality of the included studies and extracted study data. Subgroup analysis and sensitivity analysis were performed to evaluate for heterogeneity between studies. Results Of the 395 studies identified initially, 13 studies were included into our analysis, with a total of 3354 patients. Higher plasma level of TGF-β1 was associated with increased risk of AF when evaluated as both a continuous variable (SMD 0.67; 95%CI 0.29–1.05) and a categorical variable (OR 1.01, 95% CI 1.01–1.02). Conclusions This meta-analysis suggests an association between elevated plasma TGF-β1 and new onset AF. Additional studies with larger sample sizes are needed to further investigate the relationship between plasma TGF-β1 and the occurrence of AF.

Abstract
Sickle cell disease (SCD) represents a chronic inflammatory condition with complications triggered by the polymerization of hemoglobin S (Hb S), resulting in a series of cellular interactions mediated by inflammatory cytokines, as the transforming growth factor beta (TGF-β), which plays an important role in inflammation resolution. This study assessed the relation between SCD inflammation and the plasma concentration of TGF-β1, and also checked the influence of the presence of -509C/T polymorphism in TGFB1 gene on TGF-β1 plasma values. The plasma levels of TGF-β1 were quantified by ELISA in 115 patients with SCD (genotypes SS, SD-Los Angeles, Sβ-thalassemia and SC) and in 58 individuals with no hemoglobinopathies (Hb AA), as the control group. The -509C/T polymorphism in TGFB1 gene was screened by PCR-RFLP. The correlation between TGF-β1 plasma levels and the inflammation was based on its association with the count of platelets, total white blood cells (WBC) and neutrophils in the peripheral blood. Patients with SCD showed plasma levels of TGF-β1 higher than the control group, especially the Hb SS genotype, followed by the group with Hb SD. Polymorphism investigation showed no interference in the values obtained for the cytokine in the groups evaluated. All SCD groups showed TGF-β1 levels positively correlated to the platelets and WBC counts. The original data obtained in this study for SCD support the involvement of TGF-β1 in regulating of the inflammatory response and suggest that this marker possibly may become a potential therapeutic target in the treatment of the disease.

Frentzou GA, Drinkhill MJ, Turner NA, Ball SG, Ainscough JFX. A state of reversible compensated ventricular dysfunction precedes pathological remodelling in response to cardiomyocyte-specific activity of angiotensin II type-1 receptor in mice. Dis Model Mech 2015; 8:783-94. [PMID: 26092119 PMCID: PMC4527284 DOI: 10.1242/dmm.019174] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2014] [Accepted: 05/26/2015] [Indexed: 12/12/2022] Open
Abstract
Cardiac dysfunction is commonly associated with high-blood-pressure-induced cardiomyocyte hypertrophy, in response to aberrant renin-angiotensin system (RAS) activity. Ensuing pathological remodelling promotes cardiomyocyte death and cardiac fibroblast activation, leading to cardiac fibrosis. The initiating cellular mechanisms that underlie this progressive disease are poorly understood. We previously reported a conditional mouse model in which a human angiotensin II type-I receptor transgene (HART) was expressed in differentiated cardiomyocytes after they had fully matured, but not during development. Twelve-month-old HART mice exhibited ventricular dysfunction and cardiomyocyte hypertrophy with interstitial fibrosis following full receptor stimulation, without affecting blood pressure. Here, we show that chronic HART activity in young adult mice causes ventricular dysfunction without hypertrophy, fibrosis or cardiomyocyte death. Dysfunction correlated with reduced expression of pro-hypertrophy markers and increased expression of pro-angiogenic markers in the cardiomyocytes experiencing increased receptor load. This stimulates responsive changes in closely associated non-myocyte cells, including the downregulation of pro-angiogenic genes, a dampened inflammatory response and upregulation of Tgfβ. Importantly, this state of compensated dysfunction was reversible. Furthermore, increased stimulation of the receptors on the cardiomyocytes caused a switch in the secondary response from the non-myocyte cells. Progressive cardiac remodelling was stimulated through hypertrophy and death of individual cardiomyocytes, with infiltration, proliferation and activation of fibroblast and inflammatory cells, leading to increased angiogenic and inflammatory signalling. Together, these data demonstrate that a state of pre-hypertrophic compensated dysfunction can exist in affected individuals before common markers of heart disease are detectable. The data also suggest that there is an initial response from the housekeeping cells of the heart to signals emanating from distressed neighbouring cardiomyocytes to suppress those changes most commonly associated with progressive heart disease. We suggest that the reversible nature of this state of compensated dysfunction presents an ideal window of opportunity for personalised therapeutic intervention. Highlighted Article: A novel conditional mouse model was used to investigate early initiating stages of heart disease that are commonly overlooked, and identifies a ‘window of opportunity’ for personalised therapeutic intervention.

Abstract
Low-dose memantine might have anti-inflammatory and neurotrophic effects mechanistically remote from an NMDA receptor. We investigated whether add-on memantine reduced cytokine levels and benefitted patients with opioid dependence undergoing methadone maintenance therapy (MMT) in a randomized, double-blind, controlled 12-week study. Patients were randomly assigned to a group: Memantine (5 mg/day) (n = 53) or Placebo (n = 75). The methadone dose required and retention in treatment were monitored. Plasma tumor necrosis factor (TNF)-α, C-reactive protein (CRP), interleukin (IL)-6, IL-8, transforming growth factor (TGF)-β1, and brain-derived neurotrophic factor (BDNF) levels were examined during weeks 0, 1, 4, 8, and 12. General linear mixed models were used to examine therapeutic effect. After 12 weeks, Memantine-group required a somewhat lower methadone dose than did Placebo-group (P = 0.039). They also had significantly lower plasma TNF-α and significantly higher TGF-β1 levels. We provide evidence of the benefit of add-on memantine in opioid dependent patients undergoing MMT.

Delayed administration of allogeneic cardiac stem cell therapy for acute myocardial infarction could ameliorate adverse remodeling: experimental study in swine. J Transl Med 2015; 13:156. [PMID: 25964098 PMCID: PMC4458045 DOI: 10.1186/s12967-015-0512-2] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2014] [Accepted: 04/30/2015] [Indexed: 02/07/2023] Open
Abstract
Background The optimal timing of cardiac stem cells administration is still unclear. We assessed the safety of same-day and delayed (one week) delivery and the possible influence of the timing on the therapeutic outcomes of allogeneic porcine cardiac stem cells administration after acute myocardial infarction in a closed-chest ischemia-reperfusion model. Methods Female swine surviving 90 min occlusion of the mid left anterior descending coronary artery received an intracoronary injection of 25x106 porcine cardiac stem cells either two hours (n = 5, D0) or 7 days (n = 6, D7) after reperfusion. Controls received intracoronary injection of vehicle on day 7 (n = 6, CON). Safety was defined in terms of absence of major cardiac events, changes to the ECG during injection, post-administration coronary flow assessed using the TIMI scale and cardiac troponin I determination after the intervention. Cardiac Magnetic Resonance was performed for morphological and functional assessment prior to infarction, before injection (D7 and CON groups only), at one and 10 weeks. Samples were taken from the infarct and transition areas for pathological examination. Results No major adverse cardiac events were seen during injection in any group. Animals receiving the therapy on the same day of infarction (D0 group) showed mild transient ST changes during injection (n = 4) and, in one case, slightly compromised coronary flow (TIMI 2). Cardiac function parameters and infarct sizes were not significantly different between groups, with a trend towards higher ejection fraction in the treated groups. Ventricular volumes indexed to body surface area increased over time in control animals, and decreased by the end of the study in animals receiving the therapy, significantly so when comparing End Diastolic Volume between CON and D7 groups (CON: 121.70 ml/m2 ± 26.09 ml/m2, D7: 98.71 ml/m2 ± 8.30 ml/m2, p = 0.037). The treated groups showed less organization of the collagenous scar, and a significantly (p = 0.019) higher amount of larger, more mature vessels at the infarct border. Conclusions The intracoronary injection of 25x106 allogeneic cardiac stem cells is generally safe, both early and 7 days after experimental infarction, and alleviates myocardial dysfunction, with a greater limitation of left ventricular remodeling when performed at one week.

Abstract
Background Transforming growth factor beta (TGF-β1) is a pleiotropic cytokine, which is deregulated in atherosclerosis; however the role of age in this process is unknown. We aimed to assess whether TGF-β1 signaling is affected by age. Methods Vascular smooth muscle cells (VSMC) were obtained from patients undergoing abdominal surgery. Levels of TGF-β1 were measured by ELISA in sera from 169 patients undergoing coronary artery bypass grafting (CABG). The p27 expression was determined by Western blot from internal mammary arteries (IMA) obtained from CABG patients (n = 13). In VSMC from these patients undergoing abdominal surgery, secretion of TGF-β1 was determined by ELISA of cell-conditioned media. Results In VSMC from aged patients we observed a lower TGF-β1 secretion, measured as TGF-β1 concentration in cell conditioned medium (p < 0.001). This effect was correlated to an age-dependent decrease of p27 expression in IMA from aged CABG patients. In a similar manner, there was an age-dependent decrease of serum TGF-β1 levels in CABG patients (p = 0.0195). Conclusions VSMC from aged patients showed a higher degree of cellular senescence and it was associated to a lower TGF-β1 secretion and signaling.

Abstract
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in the general population; yet, the precise mechanisms resulting in AF are not fully understood. Caveolin-1 (Cav-1), the principal structural component of caveolae organelles in cardiac fibroblasts, is involved in several cardiovascular conditions; however, the study on its function in atrium, in particular, in AF, is still lacking. This report examines the hypothesis that Cav-1 confers an anti-AF effect by mediating atrial structural remodeling through its anti-fibrotic action. We evaluated the expression of Cav-1, transforming growth factor-β1 (TGF-β1), and fibrosis in atrial specimens of 13 patients with AF and 10 subjects with sinus rhythm, and found that the expression of Cav-1 was significantly downregulated, whereas TGF-β1 level, collagens I/III contents and atrial fibrosis were markedly increased, in AF. Western blot analysis demonstrated that treatment of human atrial fibroblasts (HAFs) with TGF-β1 resulted in a concentration- and time-dependent repression of Cav-1. Downregulation of Cav-1 with siRNA increased the TGF-β1-induced activation of Smad signal pathway and collagens production in HAFs. Furthermore, incubation of HAFs with the peptides derived from Cav-1 to achieve Cav-1 gain-of-function abolished the TGF-β1-induced production of collagens I/III and decreases of MMP-2/-9 expression. Therefore it was concluded that Cav-1 is an important anti-AF signaling mediator by conferring its anti-fibrotic effects in atrium.
