The clinical course of Cystic Fibrosis is characterized by recurrent pulmonary infections which ultimately lead to death by respiratory failure. The most common CF causing mutation, deltaF508-CFTR, produces an incorrectly folded protein, which accumulates within the endoplasmic reticulum. However, the molecular mechanism by which the deltaF508-CFTR protein(More)
In a study of elderly AML patients treated with the hypomethylating agent decitabine (DAC), we noted a surprisingly favorable outcome in the (usually very unfavorable) subgroup with two or more autosomal monosomies (MK2+) within a complex karyotype (Lübbert et al., Haematologica 97:393-401, 2012). We now analyzed 206 myelodysplastic syndrome (MDS) patients(More)
In previous studies we established that human bone and human osteoblast-like cells (hOB cells) cultured from bone express 5alpha-reductase (5alpha-R) activity, as demonstrated by the conversion of testosterone and androstenedione to their corresponding 5alpha-reduced metabolites, 5alpha-dihydrotestosterone (DHT) and 5alpha-androstanedione. Two 5alpha-R(More)
In the European Organisation for Research and Treatment of Cancer (EORTC)/GMDSSG phase III trial 06011, we compared decitabine (15 mg/m2 every 8 h for 3 days) with best supportive care (BSC) in patients ≥60 years with myelodysplastic syndromes (MDS) by French-American-British (FAB) criteria. Here, we reinvestigate trial 06011 for the activity and efficacy(More)
In a 52-year-old Caucasian man osteopoikilosis had been misdiagnosed roentgenologically 2 years before his death. Gradually he developed Cushing's syndrome and ultimately superior vena caval obstruction. At autopsy a primary thymic carcinoid with extensive osteoblastic bone metastasis was found. Immunohistochemically the tumor was shown to be positive for(More)
Bronchiolitis obliterans syndrome (BOS) develops in one-third of lung transplant recipients. A fibroproliferative process involving mesenchymal cells is observed histopathologically. In order further to evaluate the pathomechanisms of BOS, the gene expression of platelet-derived growth factor (PDGF)-B and transforming growth factor (TGF)-beta 1 in(More)
c-kit functions as a tyrosine kinase receptor and represents a target for small molecule kinase inhibitors. The expression pattern for c-kit was studied in different human tumor types to their correlation with prognosis. Paraffin-embedded tumor tissues from 282 patients were analyzed immunohistochemically for c-kit expression. Survival and follow-up data(More)
=27) were measured on days −2, 2, and 10. Neutrophil function was enhanced in the Filgrastim-treated group by factor 1.2 for phagocytosis (p=0.016) and 1.4 for oxidative burst (p=0.154). Leukocyte counts increased from 7.6×109/l (day −2) to a maximum of 45×109/l on day 6. No infection was reported in the study group (mean age 59.7 years; 13 men, seven(More)
A combination of chromosomal translocations associated with bcl-2 re-arrangement (t(14;18)) and c-myc re-arrangement (t(8;14), t(8;22), or t(2;8)) is a rare event. We describe the first cell line exhibiting t(14;18) and t(8;22), which will enable us to study the interactions of bcl-2 and c-myc systematically. Cell culture was started with circulating(More)
Immunologically induced T-cell lymphomas were kept for long periods of time in isotransplantation and in tissue culture. Initially, a certain number of cells within the tumor showed differentiation towards histiocytes. These disappeared completely after about the twentieth graft generation when the tumor changed toward a more atypical and more uniform(More)
