Underlying Pathogenesis

AbstractCardiovascular diseases in children comprise a large public health problem. The major goals of paediatric cardiologists and paediatric cardiovascular researchers are to identify the cause(s) of these diseases to improve treatment and preventive protocols. Recent studies show the involvement of microRNAs (miRs) in different aspects of heart development, function, and disease. Therefore, miR-based research in paediatric cardiovascular disorders is crucial for a better understanding of the underlying pathogenesis of the disease, and unravelling novel, efficient, preventive, and therapeutic means. The ultimate goal of such research is to secure normal cardiac development and hence decrease disabilities, improve clinical outcomes, and decrease the morbidity and mortality among children. This review focuses on the role of miRs in different paediatric cardiovascular conditions in an effort to encourage miR-based research in paediatric cardiovascular disorders.

It has been proposed that cardiac development in lower vertebrates is driven by the proliferation of cardiomyocytes. Similarly, cycling myocytes have been suggested to direct cardiac regeneration in neonatal mice after injury. Although, the role of cardiomyocyte proliferation in cardiac tissue generation during development has been well documented, the extent of this contribution as well as the role of other cell types, such as progenitor cells, still remains controversial. Here we used a novel stochastic four-color Cre-dependent reporter system (Rainbow) that allows labeling at a single cell level and retrospective analysis of the progeny. Cardiac progenitors expressing Mesp1 or Nkx2.5 were shown to be a source of cardiomyocytes during embryonic development while the onset of αMHC expression marked the developmental stage where the capacity of cardiac cells to proliferate diminishes significantly. Through direct clonal analysis we provide strong evidence supporting that cardiac progenitors, as opposed to mature cardiomyocytes, are the main source of cardiomyocytes during cardiac development. Moreover, we have identified quadri-, tri-, bi, and uni-potent progenitors that at a single cell level can generate cardiomyocytes, fibroblasts, endothelial and smooth muscle cells. Although existing cardiomyocytes undergo limited proliferation, our data indicates that it is mainly the progenitors that contribute to heart development. Furthermore, we show that the limited proliferation capacity of cardiomyocytes observed during normal development was enhanced following neonatal cardiac injury allowing almost complete regeneration of the scared tissue. However, this ability was largely absent in adult injured hearts. Detailed characterization of dividing cardiomyocytes and proliferating progenitors would greatly benefit the development of novel therapeutic options for cardiovascular diseases.

Progression Of Atherosclerosis

Cysteinyl leukotrienes (CysLTs) are potent lipid inflammatory mediators synthesized from arachidonic acid, through the 5-lipoxygenase (5-LO) pathway. Owing to their properties, CysLTs play a crucial role in the pathogenesis of inflammation; therefore, CysLT modifiers as synthesis inhibitors or receptor antagonists, central in asthma management, may become a potential target for the treatment of other inflammatory diseases such as the cardiovascular disorders. 5-LO pathway activation and increased expression of its mediators and receptors are found in cardiovascular diseases. Moreover, the cardioprotective effects observed by using CysLT modifiers are promising and contribute to elucidate the link between CysLTs and cardiovascular disease. The aim of this review is to summarize the state of present research about the role of the CysLTs in the pathogenesis and progression of atherosclerosis and myocardial infarction.

Knockout Animals

The multi-functional peptide adrenomedullin ( Adm = gene, AM = protein) plays important roles in embryonic development and disease. Previous studies demonstrated that Adm knockout mice die at embryonic day 13.5 with small, disorganized hearts and hypoplastic lymphatic vessels, highlighting the importance of this peptide in normal cardiovascular development. Since Adm knockout animals are embryonic lethal, our goal was to generate and characterize a novel model of Adm over-expression to study the role of Adm during development and disease processes. Through gene targeting techniques, we generated a novel mouse model of Adm over-expression, abbreviated as Adm hi/hi . When we assessed gene expression of Adm from 10 different tissues, we found Adm hi/hi mice express 3- to 15-fold more Adm than wildtype littermates. Additionally, peptide levels of AM in lung and kidney, as well as circulating plasma levels of AM were elevated 3-fold over wildtype mice, indicating a functional increase in AM. Our initial analysis revealed that adult Adm hi/hi mice have larger heart weight to body weight ratios than wildtype littermates (4.93±0.23 vs. 5.96±0.29, n = 11-12). We found that compared to wildtype, Adm hi/hi embryos have more proliferating cells during heart development (14.46±1.11 vs. 31.97±2.84, n=4), indicating that hyperplasia drives Adm hi/hi heart enlargement. By crossing the Adm hi/hi line to different tissue-specific Cre lines, we were able to excise the stabilizing bovine growth hormone 3’UTR, thereby returning Adm expression levels back to wildtype in cells with active Cre recombinase. Using this approach, we identified the epicardium as a major source of AM during cardiac development. In conclusion, we found that AM derived primarily from the epicardium drives cardiac hyperplasia during embryonic development resulting in persistent, enlarged hearts of adult Adm hi/hi mice. Since our Adm hi/hi mice recapitulate the 3-fold plasma elevation of AM observed during human disease, this mouse line will be a useful tool for studying the role of elevated AM during disease.

Chronic Morbidity

The only survey of migrant farmworkers’ health in California that used clinical exams to collect data found this occupational group had “startlingly” high rates of hypertension and risk factors for cardiovascular disease. Drawing upon the narratives of two migrant farmworking women who were both hospitalized for hypertension, this chapter explores the role of “immigration stress” and “work stress” in producing their chronic disease. While public health researchers have recently pointed to racial minorities’ physiological response to chronic discrimination as an explanation for their higher rates of hypertension, this chapter makes an analogous argument for legal minorities. It suggests that the recent trend towards heightened interior immigration enforcement subjects all noncitizens to forms of “everyday violence,” only increasing their chronic worry and “perseverative stress.” This chapter explores how the stress of being a legal minority gets under migrants’ skin, helping account for migrant farmworkers’ higher rates of chronic morbidity and mortality.

The zebrafish has become an established laboratory model for developmental studies and is increasingly used to model aspects of human development and disease. However, reviewers and grant funding bodies continue to speculate on the utility of this Himalayan minnow. In this chapter we explain the similarities and differences between the heart from this distantly related vertebrate and the mammalian heart, in order to reveal the common fundamental processes and to prevent misleading extrapolations. We provide an overview of zebrafish including their husbandry, development, peculiarities of their genome, and technological advances, which make them a highly tractable laboratory model for heart development and disease. We discuss the controversies around morphants and mutants, and relate the development and structures of the zebrafish heart to mammalian counterparts. Finally, we give an overview of regeneration in the zebrafish heart and speculate on the role of the model organism in next-generation sequencing technologies.

ObjectivesThe role of faecal haemoglobin as a colorectal cancer screening tool has been demonstrated. However, the association between the faecal haemoglobin concentration and the risk of cardiovascular disease events and deaths is still unclear.DesignCohort study design.SettingPopulation-based organised integrated service screening in Keelung City, TaiwanParticipantsA total of 33 355 healthy individuals aged over 40 years who were free of cardiovascular disease at study entry were followed up.Main outcomes and measuresNewly diagnosed cardiovascular disease events and deaths.ResultsAfter a median follow-up of 2.39 years, a total of 2768 participants developed cardiovascular events, and after a median follow-up of 8.43 years, 317 cases of cardiovascular deaths occurred. The risk of cardiovascular disease increased with baseline faecal haemoglobin in a dose–response manner, yielding a significant elevated risk of cardiovascular disease in parallel with the incremental concentration of faecal haemoglobin (adjusted HRs=1.04, 1.10, 1.40 and 1.23 for faecal haemoglobin concentrations of 1–19, 20–49, 50–99 and ≥100 ng/mL, trend test, p<0.0001, as compared with the reference group with undetectable faecal haemoglobin concentrations). A similar pattern was observed for the risk of cardiovascular disease deaths. In addition, the faecal haemoglobin improved the prediction performance of the model for the risk of cardiovascular diseases; the integrated discrimination improvement was 0.3% (p<0.001) for cardiovascular events and 0.1% (p=0.020) for cardiovascular deaths.ConclusionsOur data support that faecal haemoglobin concentrations may be associated with the risk of cardiovascular diseases. The biological mechanisms underlying the role of faecal haemoglobin as health outcomes should be investigated.
