Aspects fonctionnels, structuraux et évolutifs de la réponse transcriptionnelle à l’auxine
2017
Auxin is a plant hormone implicated in almost all plant developmental stages, since the embryo formation till flowering, determining the position of the organs in the plant and thus, its whole structure. As for any other hormone, auxin perception is followed by a signal transduction that finishes in a series of changes in a plant cell, including transcriptional changes. This thesis is divided in 3 chapters, each with a focus on the structural, molecular and evolutionary aspects of different proteins involved in the regulation of auxin genes response.First, we focused our studies on TOPLESS (TPL), a co-repressor implicated, not only in auxin responsive genes repression, but also in many othe…
La libertà sindacale fa irruzione in caserma
2021
Il commento analizza la recente giurisprudenza di merito sulla repressione della condotta antisindacale nell'ordinamento militare, alla luce dei principi costituzionali e dell'ordinamento sovranazionale, e del recente disegno di legge sul sindacato militare. The current work deals with the recent labour court decisions on anti-unions behaviours in the military legal framework, on the grounds of constitutional and international principles, and the recent bill on military unions.
ADR1 and SNF1 Mediate Different Mechanisms in Transcriptional Regulation of Yeast POT1 Gene
1994
We studied the consequences of adr1 and snf1 mutations on POT1 gene expression in different growth conditions. The results obtained reveal that ADR1 and SNF1 genes affect POT1 transcription in different ways: ADR1 has a minor role in derepression in low concentration of glucose but is essential for activation in stationary phase whereas SNF1 is essential for derepression and activation, although it does not seem to be directly involved in the molecular mechanism of activation in stationary phase.
The relative role of the T-domain and flanking sequences for developmental control and transcriptional regulation in protein chimeras of Drosophila O…
2004
optomotor-blind (omb) and optomotor-blind related-1 (org-1) encode T-domain DNA binding proteins in Drosophila. Members of this family of transcription factors play widely varying roles during early development and organogenesis in both vertebrates and invertebrates. Functional specificity differs in spite of similar DNA binding preferences of all family members. Using a series of domain swap chimeras, in which different parts of OMB and ORG-1 were mutually exchanged, we investigated the relevance of individual domains in vitro and in vivo. In cell culture transfection assays, ORG-1 was a strong transcriptional activator, whereas OMB appeared neutral. The main transcriptional activation fun…
Estrogen receptor (ER)-mediated transcriptional regulation of the human corticotropin-releasing hormone-binding protein promoter: differential effect…
2004
CRH-binding protein (CRH-BP) regulates activation of the hypothalamic-pituitary-adrenal (HPA) axis by binding and inhibiting CRH. We investigated for the first time transcriptional regulation of the human CRH-BP promoter using transient transfections. Estrogen receptors (ERs) contributed to ligand-independent constitutive activation of the promoter, whereas in the presence of estradiol ERalpha induced and ERbeta repressed promoter activity in a dose-dependent manner. TNFalpha inhibited promoter induction by ERalpha in the absence and presence of estradiol. Three ERE half-sites in the CRH-BP promoter bound ERalpha and ERbeta in an EMSA, and disruption of ERE half-sites by site-directed mutag…
The mediating role of emotion regulation in transdiagnostic cognitive behavioural therapy for emotional disorders in primary care: Secondary analyses…
2022
Background: Emotional disorders are highly prevalent in primary care. Transdiagnostic cognitive behavior therapy (TD-CBT) is a promising treatment of emotional disorders. In this study, we evaluated several emotion regulation strategies as potential mediators of treatment outcomes in a clinical sample of primary care. Methods: A total of 1061 primary care patients were included in a randomized clinical trial comparing treatment- as-usual (TAU) to TD-CBT+TAU. Of these, 631 (TAU=316; TD-CBT+TAU=315) completed the full treatment and all pre- and post-treatment scales to assess symptoms (anxiety, depression, somatization), emotion regulation strategies (worry, rumination, negative metacognition…
Efficacy and cost-effectiveness of guided and unguided internet- and mobile-based indicated transdiagnostic prevention of depression and anxiety (ICa…
2019
Background Depression and anxiety are highly prevalent and often co-occur. Several studies indicate the potential of disorder-specific psychological interventions for the prevention of each of these disorders. To treat comorbidity, transdiagnostic treatment concepts seem to be a promising approach, however, evidence for transdiagnostic concepts of prevention remains inconclusive. Internet- and mobile-based interventions (IMIs) may be an effective means to deliver psychological interventions on a large scale for the prevention of common mental disorders (CMDs) such as depression and anxiety. IMIs have been shown to be effective in treating CMDs, e.g. in reducing symptoms of depression and an…
Nursing students and depressive symptomatology: an observational study in University of Palermo
2019
Purpose Depression is a common and serious medical illness, considered as a public health issue because it interferes with the interpersonal, social and professional functioning of the individual, and its frequency is constantly increasing. According to a recent review, approximately 34 per cent of nursing students had experienced depression worldwide. The university period may represent a moment in which the mental well-being of students is subjected to stress with a relative predisposition to the development of diseases related to mood disorders. The purpose of this study is to estimate the prevalence and examine the socio-demographic correlates of depressive symptomatology. Design/metho…
Factors Differentiating Rural and Urban Population in Determining Anxiety and Depression in Patients with Chronic Cardiovascular Disease: A Pilot Stu…
2021
The aim of this cross-sectional study was to analyze selected variables differentiating rural from urban populations, as well as identify potentially increased levels of depression and anxiety in patients with chronic cardiovascular disease. The study was carried out in 193 patients. The study used the Camberwell Assessment of Need Short Appraisal Schedule (CANSAS), the Health Behavior Inventory Questionnaire (HBI), the WHOQOL-BREF Quality of Life Questionnaire, and the Hospital Anxiety and Depression Scale–Modified Version (HADS-M). Spearman’s rank correlation coefficient test and logistic regression were used for analyses. In rural patients, we observed a relationship between anxiety and …
Human Papilloma Virus-Dependent HMGA1 Expression Is a Relevant Step in Cervical Carcinogenesis
2008
HMGA1 is a member of a small family of architectural transcription factors involved in the coordinate assembly of multiprotein complexes referred to as enhanceosomes. In addition to their role in cell proliferation, differentiation, and development, high-mobility group proteins of the A type (HMGA) family members behave as transforming protoncogenes either in vitro or in animal models. Recent reports indicated that HMGA1 might counteract p53 pathway and provided an interesting hint on the mechanisms determining HMGA's transforming potential. HMGA1 expression is deregulated in a very large array of human tumors, including cervical cancer, but very limited information is available on the mole…
