Abstract: Metastatic progression of breast cancer is still a challenge in clinical oncology. Therefore, an elucidation how carcinoma cells belonging to different breast cancer subtypes realize their metastatic capacities is needed. The aim of this study was to elucidate a similarity of activated molecular pathways underlying an enhancement of invasiveness of carcinoma cells belonging to different breast carcinoma subtypes. Materials and methods. In order to reach this aim, parental and invasive (INV) MDA-MB-231 (triple-negative), T47D (hormone receptor-positive), and Au565 (Her2-positive) breast carcinoma cells were used and their molecular phenotypes were compared using a proteomic approach. Results. Independently from breast cancer subtypes, INV cells have demonstrated fibroblast-like morphology accompanied by enhancement of invasive and migratory capacities, increased expression of cancer stem cell markers, and delayed tumor growth in in vivo animal models. However, the global proteomic analysis has highlighted that INV cells were different in protein expressions from the parental cells, and Her2-positive Au565-INV cells showed the most pronounced molecular differences compared to the triple-negative MDA-MB-231-INV and hormone receptor-positive T47D-INV cells. Although Au565-INV breast carcinoma cells possessed the highest number of deregulated proteins, they had the lowest overlapping in proteins commonly expressed in MDA-MB-231-INV and T47D-INV cells. Conclusions. We can conclude that hormone receptor-positive cells with increased invasiveness acquire the molecular characteristics of triple-negative breast cancer cells, whereas Her2-positive INV cells specifically changed their own molecular phenotype with very limited partaking in the involved pathways found in the MDA-MB-231-INV and T47D-INV cells. Since hormone receptor-positive invasive cells share their molecular properties with triple-negative breast cancer cells, we assume that these types of metastatic disease can be treated rather equally with an option to add anti-hormonal agents. In contrast, Her2-positive metastasis should be carefully evaluated for more effective therapeutic approaches which are distinct from the triple-negative and hormone-positive metastatic breast cancers.

Abstract: Adolescents present a relevant stakeholder in international migrations since they comprise a large share of all migrants. Previous studies show that migration processes significantly affect the well-being of migrant adolescents. This article investigates how the school environment, with its pedagogical practices and interpersonal relationships established between migrant adolescents, their classmates, and teachers, affect migrant adolescents’ well-being. Our research draws on quantitative data collected as part of the MiCREATE project. The sample of migrant adolescents (N = 700) was surveyed in 46 schools in six countries: Austria, Denmark, Slovenia, Spain, Poland, and the United Kingdom. Results indicate that migrant adolescents like school and feel safe there, however, they tend to be more satisfied with relationships established with teachers than with peers. Furthermore, differences in self-perceived school well-being emerge when comparing countries with a longer tradition of high migration flows (Spain, Denmark, and the United Kingdom) and those less experienced (Poland and Slovenia), although slight exceptions were detected. The results lead to the conclusion that schools that foster intercultural education and fulfilling interpersonal relationships are essential for school well-being of migrant adolescents and present an important step toward successful integration of migrant youth.

Abstract: Based on field research in Slovenian schools, the article examines the role of the family in the integration process of migrant children. While migrant children perceive the family as the most important factor influencing their overall well-being and life satisfaction, research shows that parents of migrant children are often not involved in school activities and life. The article explores how the role of parents in the integration process of migrant children in the school environment is understood at the policy level and how it is perceived by migrant children and the educational community. It also explores what are the main barriers to the involvement of migrant parents in schools and what are the existing practices and experiences in Slovenian schools. The analysis is based on qualitative research in Slovenian schools with children and the educational community conducted as part of the Migrant Children and Communities in a Transforming Europe (MiCREATE) project.
