    The principle of promoting free mobility of citizens has been written into European educational policies. Additionally, the philosophy of educational equality has been clearly included into the educational regulation of most European countries. Furthermore, at the beginning of the twenty-first century the ideas of lifelong learning have been defined to be the goals of improving practice within the educational systems. This means that teachers all over Europe are increasingly facing students with various ethnic backgrounds of all ages and having varied educational backgrounds, life situations and work-experiences and accordingly, being in the need of diverse educational support within educational settings. The growth in demands for equal educational rights for all inevitably strengthens the demands for the development of each teacher’s and counsellor's the skills of the teaching and counselling staff for meeting the individual needs of learners emerging from diverse reasons and counselling them accordingly. However, with this new concentration on the needs of diverse students emerging on issues like immigration, age, race, gender, special educational needs or the like, there seems to be some uncertainty with regards to what the development of these skills might mean for the practices of educational settings, their teachers and other staff and, accordingly, for teacher education training professionals for educational settings. In this article we will provide the reader with a couple of examples of how these challenges have been met within educational settings. Besides offering some examples of good practice of working with immigrant adults we also focus on the challenge of training professionals and in particular to of training teachers working with immigrant adults in educational provisions institutions. With In putting the focus on teachers we would like to underline the importance of every teacher to have having the counselling attitude and skills in his/her everyday practice with immigrant adult learners besides the work done by actual counselling professionals. However, we start our article with by addressing briefly the subject of to adult learners and some grounds of working with immigrant adult learners in educational settings. This starting point provides the conceptual framework for the practical examples to be presented. The first two of these examples are dealing deal with counselling immigrant adult students. They are followed with by examples of some learning tools used in training teachers to work with multicultural adult students

    RNA Binding to CBP Stimulates Histone Acetylation and Transcription

    Get PDF
    CBP/p300 are transcription co-activators whose binding is a signature of enhancers, cis-regulatory elements that control patterns of gene expression in multicellular organisms. Active enhancers produce bi-directional enhancer RNAs (eRNAs) and display CBP/p300-dependent histone acetylation. Here, we demonstrate that CBP binds directly to RNAs in vivo and in vitro. RNAs bound to CBP in vivo include a large number of eRNAs. Using steady-state histone acetyltransferase (HAT) assays, we show that an RNA binding region in the HAT domain of CBP—a regulatory motif unique to CBP/p300—allows RNA to stimulate CBP’s HAT activity. At enhancers where CBP interacts with eRNAs, stimulation manifests in RNA-dependent changes in the histone acetylation mediated by CBP, such as H3K27ac, and by corresponding changes in gene expression. By interacting directly with CBP, eRNAs contribute to the unique chromatin structure at active enhancers, which, in turn, is required for regulation of target genes

    AbstractThis 36-month study aimed to determine whether exercise intervention added to weight loss treatment in the beginning or at 6 months is effective for weight loss and long-term weight maintenance. A total of 120 obese adults (body mass index >30) were randomly assigned to intensified behavioral modification (iBM), iBM+ additional exercise from 0 to 3 months (CWT1), iBM+ additional exercise from 6 to 9 months (CWT2), and a control group (CON). Questionnaires and measurements were collected at baseline, 3, 9, 24, and 36 months. The intervention consisted of an 12 months intensified weight-loss period followed by a 24 months weight-maintenance period. Eighty (67%) subjects (mean age 46.0 years, BMI 36.2) completed the trial.

The intervention consisted of an 12 months intensified weight-loss period followed by a 24 months weight-maintenance period. Eighty (67%) subjects (mean age 46.0 years, BMI 36.2) completed the trial. Compared with the control group, all three intervention groups had significant weight loss during the 36-month intervention period (p < 0.001). The achieved weight loss remained significant at 36 months in the iBM (−6.8%, p < 0.001), the CWT1 (−5.8%, p < 0.001), and the CWT2 group (−3.9%, p < 0.001). The CWT1 group showed significant reduction in waist circumference at 9 months (−11.3 cm, p < 0.001), at 24 months (−8.8 cm, p < 0.001), and at 36 months (−8.7 cm, p < 0.001). Intensified behavioral modification alone and with exercise resulted in clinically significant weight loss and long-term weight maintenance. The addition of exercise at the onset promoted greater reductions in waist circumference. In the treatment of obesity, including severe obesity, more intensive lifestyle interventions with exercise should be incorporated

    Epigenetic therapy has gained interest in treating cardiovascular diseases, but preclinical studies often encounter challenges with cell-type-specific effects or batch-to-batch variation, which have limited identification of novel drug candidates targeting angiogenesis. To address these limitations and improve the reproducibility of epigenetic drug screening, we redesigned a 3D in vitro fibrin bead assay to utilize immortalized human aortic endothelial cells (TeloHAECs) and screened a focused compound library with 105 agents. Compared to the established model using primary human umbilical vein endothelial cells, TeloHAECs needed a higher-density fibrin gel for optimal sprouting, successfully forming sprouts under both normoxic and hypoxic cell culture conditions. We identified two epigenetic enzyme inhibitors as novel regulators of sprouting angiogenesis: A196, a selective SUV4-20H1/H2 inhibitor, demonstrated pro-angiogenic effects through increased H4K20me1 levels and upregulation of cell cycle associated genes, including MCM2 and CDK4. In contrast TMP-269, a selective class IIa HDAC inhibitor, exhibited anti-angiogenic effects by downregulating angiogenesis-related proteins and upregulating pro-inflammatory signaling. These findings highlight the suitability of the modified TeloHAEC fibrin bead assay for drug screening purposes and reveal both pro-angiogenic and anti-angiogenic drug candidates with therapeutic potential

    Abstract α-Melanocyte-stimulating hormone (α-MSH) regulates diverse physiological functions by activating melanocortin receptors (MC-R). However, the role of α-MSH and its possible target receptors in the heart remain completely unknown. Here we investigate whether α-MSH could be involved in pathological cardiac remodeling. We found that α-MSH was highly expressed in the mouse heart with reduced ventricular levels after transverse aortic constriction (TAC). Administration of a stable α-MSH analog protected mice against TAC-induced cardiac hypertrophy and systolic dysfunction. In vitro experiments revealed that MC5-R in cardiomyocytes mediates the anti-hypertrophic signaling of α-MSH. Silencing of MC5-R in cardiomyocytes induced hypertrophy and fibrosis markers in vitro and aggravated TAC-induced cardiac hypertrophy and fibrosis in vivo. Conversely, pharmacological activation of MC5-R improved systolic function and reduced cardiac fibrosis in TAC-operated mice. In conclusion, α-MSH is expressed in the heart and protects against pathological cardiac remodeling by activating MC5-R in cardiomyocytes. These results suggest that analogs of naturally occurring α-MSH, that have been recently approved for clinical use and have agonistic activity at MC5-R, may be of benefit in treating heart failure.Abstract α-Melanocyte-stimulating hormone (α-MSH) regulates diverse physiological functions by activating melanocortin receptors (MC-R).

    RATIONALE: Atherosclerotic lesions are known for their cellular heterogeneity, yet the molecular complexity within the cells of human plaques has not been fully assessed. OBJECTIVE: Using single-cell transcriptomics and chromatin accessibility, we gained a better understanding of the pathophysiology underlying human atherosclerosis. METHODS AND RESULTS: We performed single-cell RNA and single-cell ATAC sequencing on human carotid atherosclerotic plaques to define the cells at play and determine their transcriptomic and epigenomic characteristics. We identified 14 distinct cell populations including endothelial cells, smooth muscle cells, mast cells, B cells, myeloid cells, and T cells and identified multiple cellular activation states and suggested cellular interconversions. Within the endothelial cell population, we defined subsets with angiogenic capacity plus clear signs of endothelial to mesenchymal transition. CD4+ and CD8+ T cells showed activation-based subclasses, each with a gradual decline from a cytotoxic to a more quiescent phenotype. Myeloid cells included 2 populations of proinflammatory macrophages showing IL (interleukin) 1B or TNF (tumor necrosis factor) expression as well as a foam cell-like population expressing TREM2 (triggering receptor expressed on myeloid cells 2) and displaying a fibrosis-promoting phenotype. ATACseq data identified specific transcription factors associated with the myeloid subpopulation and T cell cytokine profiles underlying mutual activation between both cell types. Finally, cardiovascular disease susceptibility genes identified using public genome-wide association studies data were particularly enriched in lesional macrophages, endothelial, and smooth muscle cells. CONCLUSIONS: This study provides a transcriptome-based cellular landscape of human atherosclerotic plaques and highlights cellular plasticity and intercellular communication at the site of disease. This detailed definition of cell communities at play in atherosclerosis will facilitate cell-based mapping of novel interventional targets with direct functional relevance for the treatment of human diseas

    Secreted frizzled-related protein 2 (SFRP2) expression promotes lesion proliferation via canonical WNT signaling and indicates lesion borders in extraovarian endometriosis

    Get PDF
    STUDY QUESTION: What is the role of SFRP2 in endometriosis?SUMMARY ANSWER: SFRP2 acts as a canonical WNT/CTNNBI signaling agonist in endometriosis, regulating endometriosis lesion growth and indicating endometriosis lesion borders together with CTNNBI (also known as beta catenin).WHAT IS KNOWN ALREADY: Endometriosis is a common, chronic disease that affects women of reproductive age, causing pain and infertility, and has significant economic impact on national health systems. Despite extensive research, the pathogenesis of endometriosis is poorly understood, and targeted medical treatments are lacking. WNT signaling is dysregulated in various human diseases, but its role in extraovarian endometriosis has not been fully elucidated.STUDY DESIGN, SIZE, DURATION: We evaluated the significance of WNT signaling, and especially secreted frizzled-related protein 2 (SFRP2), in extraovarian endometriosis, including peritoneal and deep lesions. The study design was based on a cohort of clinical samples collected by laparoscopy or curettage and questionnaire data from healthy controls and endometriosis patients.PARTICIPANTS/MATERIALS, SETTING, METHODS: Global gene expression analysis in human endometrium ( n = 104) and endometriosis (n = 177) specimens from 47 healthy controls and 103 endometriosis patients was followed by bioinformatics and supportive qPCR analyses. Immunohistochemistry, Western blotting, primary cell culture and siRNA knockdown approaches were used to validate the findings.MAIN RESULTS AND THE ROLE OF CHANCE: Among the 220 WNT signaling and CTNNBI target genes analysed, 184 genes showed differential expression in extraovarian endometriosis (P < 0.05) compared with endometrium tissue, including SFRP2 and CTNNI. Menstrual cycle-dependent regulation of WNT genes observed in the endometrium was lost in endometriosis lesions, as shown by hierarchical clustering. Immunohistochemical analysis indicated that SFRP2 and CTNNBI are novel endometriosis lesion border markers, complementing immunostaining for the known marker CD10 (also known as MME). SFRP2 and CTNNBI localized similarly in both the epithelium and stroma of extraovarian endometriosis tissue, and interestingly, both also indicated an additional distant lesion border, suggesting that WNT signaling is altered in the endometriosis stroma beyond the primary border indicated by the known marker CD10. SFRP2 expression was positively associated with pain symptoms experienced by patients (P < 0.05), and functional loss of SFRP2 in extraovarian endometriosis primary cell cultures resulted in decreased cell proliferation (P < 0.05) associated with reduced CTNNBI protein expression (P = 0.05).LIMITATIONS REASONS FOR CAUTION: SFRP2 and CTNNBI improved extraovarian endometriosis lesion border detection in a relatively small cohort (n = 20), although larger studies with different endometriosis subtypes in variable cycle phases and under hormonal medication are required.WIDER IMPLICATIONS OF THE FINDINGS: The highly expressed SFRP2 and CTNNBI improve endometriosis lesion border detection, which can have clinical implications for better visualization of endometriosis lesions over CD10. Furthermore, SFRP2 acts as a canonical WNT/CTNNBI signaling agonist in endometriosis and positively regulates endometriosis lesion growth, suggesting that the WNT pathway may be an important therapeutic target for endometriosis

    Reference values of whole-blood fatty acids by age and sex from European children aged 3-8 years

    OBJECTIVES: To establish reference values for fatty acids (FA) especially for n-3 and n-6 long-chain polyunsaturated FAs (LC PUFA) in whole-blood samples from apparently healthy 3-8-year-old European children. The whole-blood FA composition was analysed and the age-and sex-specific distribution of FA was determined. DESIGN AND SUBJECTS: Blood samples for FA analysis were taken from 2661 children of the IDEFICS (identification and prevention of dietary-and lifestyle-induced health effects in children and infants) study cohort. Children with obesity (n = 454) and other diseases that are known to alter the FA composition (n = 450) were excluded leaving 1653 participants in the reference population. MEASUREMENTS: The FA composition of whole blood was analysed from blood drops by a rapid, validated gas chromatographic method. RESULTS: Pearson correlation coefficients showed an age-dependent increase of C18:2n-6 and a decrease of C18:1n-9 in a subsample of normal weight boys and girls. Other significant correlations with age were weak and only seen either in boys or in girls, whereas most of the FA did not show any age dependence. For age-dependent n-3 and n-6 PUFA as well as for other FA that are correlated with age (16:0, C18:0 and C18:1n-9) percentiles analysed with the general additive model for location scale and shape are presented. A higher median in boys than in girls was observed for C20:3n-6, C20:4n-6 and C22:4n-6. CONCLUSIONS: Given the reported associations between FA status and health-related outcome, the provision of FA reference ranges may be useful for the interpretation of the FA status of children in epidemiological and clinical studies
