Vezatin, a novel transmembrane protein, bridges myosin VIIA to the cadherin-catenins complex
2000
International audience; Defects in myosin VIIA are responsible for deafness in the human and mouse. The role of this unconventional myosin in the sensory hair cells of the inner ear is not yet understood. Here we show that the C-terminal FERM domain of myosin VIIA binds to a novel transmembrane protein, vezatin, which we identi®ed by a yeast two-hybrid screen. Vezatin is a ubiquitous protein of adherens cell±cell junctions, where it interacts with both myosin VIIA and the cadherin±catenins complex. Its recruitment to adherens junctions implicates the C-terminal region of a-catenin. Taken together, these data suggest that myosin VIIA, anchored by vezatin to the cadherin±catenins complex, cre…
PED in 2021: a major update of the protein ensemble database for intrinsically disordered proteins
2020
Abstract The Protein Ensemble Database (PED) (https://proteinensemble.org), which holds structural ensembles of intrinsically disordered proteins (IDPs), has been significantly updated and upgraded since its last release in 2016. The new version, PED 4.0, has been completely redesigned and reimplemented with cutting-edge technology and now holds about six times more data (162 versus 24 entries and 242 versus 60 structural ensembles) and a broader representation of state of the art ensemble generation methods than the previous version. The database has a completely renewed graphical interface with an interactive feature viewer for region-based annotations, and provides a series of descriptor…
Factors Associated With Fatigue After Surgery in Women With Early-Stage Invasive Breast Cancer
2013
Abstract Learning Objectives Describe the effect of worsening fatigue after breast cancer surgery on physical functioning and psychological distress. Better identify women at risk for developing cancer-related fatigue. Direct target interventions to patients most in need. Purpose. Fatigue is one of the most frequent symptoms in patients with cancer. However, the precise determinants of fatigue are still unknown. This study was conducted to investigate factors correlated with cancer-related fatigue before surgery and just before subsequent adjuvant therapy. Methods. Patients completed the Multidimensional Fatigue Inventory (MFI-20), the European Organization for Research and Treatment of Can…
The EORTC computer-adaptive tests measuring physical functioning and fatigue exhibited high levels of measurement precision and efficiency
2013
Objectives: The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group is developing a computer-adaptive test (CAT) version of the EORTC Quality of Life Questionnaire (QLQ-C30). We evaluated the measurement properties of the CAT versions of physical functioning (PF) and fatigue (FA) and compared these with the corresponding QLQ-C30 scales. Study Design and Setting: Based on international samples of more than 1,000 cancer patients, we simulated CAT administration of varying numbers of items and compared the resulting scores with those based on all items in the respective item pools. Furthermore, the relative validity (RV) of CATs was compared with that of th…
The neural feedback loop between the brain and adipose tissues
2009
Communication également publiée dans le livre "Adipose tissue development: from animal models to clinical conditions" (ISBN 978-3-8055-9450-9) de C. Levy-Marchal et L. Pénicaud (eds); There are more and more data supporting the importance of nervous regulation of both white and brown adipose tissue mass. This short paper will review the different physiological parameters which are regulated such as metabolism (lipolysis and thermogeneis), secretory activity (leptin and other adipokines) but also to plasticity of adipose tissues (proliferation differentiation and apoptosis). The sensory innervation of white adipose issue and its putative role will be also described. Altogether these results …
Using a Multi-Locus Microsatellite Typing method improved phylogenetic distribution of Candida albicans isolates but failed to demonstrate associatio…
2012
EA MERS CT3 Enjeu 3; International audience; The dimorphic yeast Candida albicans is a component of the normal microflora at the mucosal surfaces of healthy individuals. It possesses an array of phenotypic properties considered as virulence traits that contribute to pathogenicity of the yeast in immuno-compromised patients. We addressed the question of the pathogenicity of lineages of C. albicans with regard to their genotype in three series of C. albicans isolates (a series of commensal isolates collected in healthy individuals, a group of bloodstream isolates and a group of non-bloodstream clinical isolates) using a Multi-Locus Microsatellite Typing (MLMT) approach based on the analysis o…
Use of CDC2 from etoposide-treated cells as substrate to assay CDC25 phosphatase activity
1999
International audience; Cyclin-dependent kinases (CDKs) regulate the key transition of the cell cycle in all organisms. In response to Etoposide (VP-16) induced DNA damage, cells undergo a G2-phase arrest resulting in the accumulation of inactive CDK1 (CDC2) kinase complexes. Here we report that upon Etoposide treatment CDC2 is phosphorylated on tyrosine 15 and is dephosphorylated and activated in vitro by recombinant CDC25 phosphatase. We also show that inactive CDC2 kinase from Etoposide-treated cells can be used as a substrate in a sensitive two-step assay of CDC25 phosphatase. This assay, which is very simple to set-up, is based on the monitoring of CDC2 kinase activity after CDC25-depe…
[Exercices program and rehabilitation of motor disorders in Parkinson's disease].
2000
International audience; As long as motor disorders are controlled by DOPAtherapy, exercise programs and rehabilitation would not appear to be essential for patients suffering from Parkinson's disease. Such measures do become necessary however when secondary occurrence of motor decline develops. Physical medicine and rehabilitation have not been really involved in Parkinson's disease and few articles have assessed the value of these programs. In fact, controlled randomized studies have faced two kinds of methodological difficulties, those due to rehabilitation practices, and those due to Parkinson's disease specificity, especially similarities between groups for Hoehn and Yahr stage at study…
[Vaccination against papillomavirus : arguments and evidence of effectiveness].
2020
Vaccination against papillomavirus: arguments and evidence of effectiveness. Vaccination against human papillomavirus is a major advance in the prevention of cervical cancer. Evidence of its effectiveness has accumulated over the past thirty years since basic research has demonstrated the ability of viral pseudoparticles to induce immune responses in animals. Large human clinical trials followed to demonstrate the safety and efficacy of vaccination against targeted HPV infections and their associated lesions. After its approval and marketing the vaccine efficacy was measured at the level of entire populations, confirming its effectiveness and medical interest. Today, models predict a possib…
Bimodal Recovery Pattern in Human Skeletal Muscle Induced by Exhaustive Stretch-Shortening Cycle Exercise:
2007
Introduction/Purpose: Recovery of force and stretch reflex from exhaustive stretch-shortening cycle (SSC) exercise is usually bimodal, characterized as immediate exercise-induced performance reduction, with its quick recovery followed by a longer-lasting reduction in performance. A clear parallel exists between the respective changes in performance, neural activation, and metabolic or structural exercise-induced changes. This implies the existence of potential coupling between muscle failure and the induced neural adjustments that take place along its recovery. The present study was designed to explore the evidence of this coupling more thoroughly. Methods: H- and stretch reflexes were meas…
