The murine mCLCA3 (alias gob-5) protein is located in the mucin granule membranes of intestinal, respiratory, and uterine goblet cells. 总被引:8,自引:0,他引:8
The putative anion channel mCLCA3 (alias gob-5) is the third murine member of the recently discovered family of calcium-activated chloride channels (CLCA family). Preliminary data suggest that mCLCA3 may play a significant role in diseases with secretory dysfunctions, including asthma and cystic fibrosis. In this study, the mCLCA3 protein was characterized biochemically and its cellular and subcellular distribution pattern was established in normal murine tissues. Polyclonal rabbit antibodies were generated and affinity-immunopurified using synthetic oligopeptides corresponding to the extracellular amino terminus of the mCLCA3 polypeptide. After in vitro translation and glycosylation, proteinase K protection assay, and heterologous expression in COS-7 or HEK 293 cells, SDS-PAGE and immunoblotting revealed a protein structure similar to that of previously characterized CLCA proteins. A systematic light, confocal laser scanning, and transmission electron microscopic immunolocalization study, including virtually all murine tissues, identified the mCLCA3 protein exclusively associated with mucin granule membranes of gastrointestinal, respiratory, and uterine goblet cells and other mucin-producing cells. The results suggest that mCLCA3 may be involved in the synthesis, condensation, or secretion of mucins. 相似文献

ABSTRACT: BACKGROUND: Antithrombotic treatment is a continuous therapy that is often performed in general practice and requires careful safety management. The aim of this study is to investigate whether a best practice model that applies major elements of case management, including patient education, can improve antithrombotic management in primary health care in terms of reducing major thromboembolic and bleeding events. METHODS: This 24-month cluster-randomized trial will be performed in 690 adult patients from 46 practices. The trial intervention will be a complex intervention involving general practitioners, health care assistants and patients with an indication for oral anticoagulation. To assess adherence to medication and symptoms in patients, as well as to detect complications early, health care assistants will be trained in case management and will use the Coagulation-Monitoring-List (Co-MoL) to regularly monitor patients. Patients will receive information (leaflets and a video), treatment monitoring via the Co-MoL and be motivated to perform self-management. Patients in the control group will continue to receive treatment-as-usual from their general practitioners. The primary endpoint is the combined endpoint of all thromboembolic events requiring hospitalization, and all major bleeding complications. Secondary endpoints are mortality, hospitalization, strokes, major bleeding and thromboembolic complications, severe treatment interactions, the number of adverse events, quality of anticoagulation, health-related quality of life and costs. Further secondary objectives will be investigated to explain the mechanism by which the intervention is effective: patients' assessment of chronic illness care, self-reported adherence to medication, general practitioners' and health care assistants' knowledge, patients' knowledge and satisfaction with shared decision making. Practice recruitment is expected to take place between July and December 2012. Recruitment of eligible patients will start in July 2012. Assessment will occur at three time points: baseline (T0), follow-up after 12 (T1) and after 24 months (T2). DISCUSSION: The efficacy and effectiveness of individual elements of the intervention, such as antithrombotic interventions, self-management concepts in orally anticoagulated patients and the methodological tool, case-management, have already been extensively demonstrated. This project foresees the combination of several proven instruments, as a result of which we expect to profit from a reduction in the major complications associated with antithrombotic treatment. 相似文献
